Deep Research MCP

A Python-based agent that integrates research providers with Claude Code through the Model Context Protocol (MCP). It supports OpenAI (Responses API with web search and code interpreter, Chat Completions API for broad provider compatibility, or experimental ChatGPT subscription access through Codex OAuth), Gemini Deep Research via the Interactions API, Allen AI's DR-Tulu research agent, and the open-source Open Deep Research stack (based on smolagents).

Prerequisites

• Python 3.11+
• uv installed
• One of:
  • OpenAI API access (Responses API model gpt-5.6-sol)
  • ChatGPT subscription with Codex access (experimental openai-codex provider)
  • Gemini API access with the Interactions API / Deep Research agent enabled
  • DR-Tulu service running locally or remotely (see DR-Tulu setup)
  • Open Deep Research dependencies (installed via uv sync --extra open-deep-research)
• Claude Code, or any other assistant supporting MCP integration

Installation

Run Without Cloning

With uv and Git installed, run the packaged commands directly from GitHub. uvx builds an isolated environment and reuses it from the local uv cache:

uvx --from "git+https://github.com/pminervini/deep-research-mcp.git@main" \
  deep-research-cli --help

uvx --from "git+https://github.com/pminervini/deep-research-mcp.git@main" \
  deep-research-mcp --help

For reproducible installation, replace main with a release tag or commit SHA. The openai-codex device login is also available without a checkout:

uvx --from "git+https://github.com/pminervini/deep-research-mcp.git@main" \
  deep-research-cli auth login

Source Checkout

Recommended development setup (resolves the latest compatible versions):

# Install runtime dependencies + project in editable mode
uv sync --upgrade

# Development tooling (pytest, black, pylint, mypy, pre-commit)
uv sync --upgrade --extra dev

# Enable the pre-commit hook so black runs automatically before each commit
uv run pre-commit install

# Optional docs tooling
uv sync --upgrade --extra docs

# Optional Open Deep Research provider dependencies
uv sync --upgrade --extra open-deep-research

Compatibility setup (pip-based):

python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
pip install -e .

• cli/deep-research-cli.py: compatibility wrapper for source-checkout usage
• cli/deep-research-tui.py: interactive full-screen terminal UI for research, status checks, and saving output to disk
• tests/: pytest suite covering configuration, MCP integration, results, and UI flows

Configuration

Configuration File

Create a ~/.deep_research file in your home directory using TOML format.

Library note: ResearchConfig.load() explicitly reads this file and applies environment variable overrides. ResearchConfig.from_env() reads environment variables only.

Common settings:

[research]                                  # Core Deep Research functionality
provider = "openai"                         # Available options: "openai", "openai-codex", "dr-tulu", "gemini", "open-deep-research" -- defaults to "openai"
api_style = "responses"                     # Only applies to provider="openai"; use "chat_completions" for Perplexity, Groq, Ollama, etc.
model = "gpt-5.6-sol"                       # OpenAI: model identifier; Codex: "auto" or account model slug; Dr Tulu: logical provider id; Gemini: agent id; ODR: LiteLLM model identifier
api_key = "your-api-key"                    # API key, optional
base_url = "https://api.openai.com/v1"      # OpenAI: OpenAI-compatible endpoint; Codex uses a fixed endpoint; Dr Tulu: service base URL; Gemini: https://generativelanguage.googleapis.com; ODR: LiteLLM-compatible endpoint

# Task behavior
timeout = 1800
poll_interval = 30
cancel_on_timeout = false  # When true, cancel the provider task if it exceeds timeout. Default false: the task keeps running and the result can be recovered with research_status

[logging]
level = "INFO"

Note on precedence: [research] api_key and base_url map to the RESEARCH_API_KEY and RESEARCH_BASE_URL settings, which apply to every provider except openai-codex. The Codex subscription provider ignores API keys and endpoint overrides so its bearer token cannot be redirected. If you switch another provider via an environment override (e.g. RESEARCH_PROVIDER=openai) while the file is configured for a different provider, also override RESEARCH_API_KEY and RESEARCH_BASE_URL.

OpenAI provider example:

[research]
provider = "openai"
model = "gpt-5.6-sol"                       # OpenAI model
api_key = "YOUR_OPENAI_API_KEY"             # Defaults to OPENAI_API_KEY
base_url = "https://api.openai.com/v1"      # OpenAI-compatible endpoint
timeout = 1800
poll_interval = 30

OpenAI Codex subscription provider example:

[research]
provider = "openai-codex"
model = "auto"                              # First picker-visible account model
timeout = 1800

Authenticate before starting the CLI or MCP server:

# Recommended: independent device-code session
uv run deep-research-cli auth login

# Optional short-lived import; never copies the Codex refresh token
uv run deep-research-cli auth login --import-codex

uv run deep-research-cli auth status

Credentials are stored independently in ~/.deep_research_auth.json with owner-only permissions. auth logout removes only this file. Model names are loaded from the signed-in account's /models catalogue; an explicit model must be present in that catalogue.

This provider uses the undocumented https://chatgpt.com/backend-api/codex consumer endpoint. It is not an official OpenAI API integration and can change or reject third-party clients without notice. It identifies itself as deep_research_mcp and does not impersonate the Codex CLI. Review the current OpenAI Terms of Use before enabling it.

Limitations:

• Native web search is enabled, but Code Interpreter is unavailable.
• Calls are synchronous SSE streams; research_status, completed-report recovery, background polling, and cancel_on_timeout are unavailable.
• Imported Codex credentials cannot refresh. Run auth login when the imported access token expires.

Gemini Deep Research provider example:

[research]
provider = "gemini"
model = "deep-research-preview-04-2026"     # Gemini Deep Research agent id
api_key = "YOUR_GEMINI_API_KEY"                # Defaults to GEMINI_API_KEY or GOOGLE_API_KEY
base_url = "https://generativelanguage.googleapis.com"
timeout = 1800
poll_interval = 30

Available Gemini Deep Research agent IDs:

Google's current Gemini Deep Research documentation lists the April 2026 standard and Max agents as the supported versions. The December 2025 Pro agent remains present in the Gemini API model catalogue and has a separate model page, but it is no longer listed among the current supported versions. Set any agent ID above as research.model; all are preview identifiers and may change.

Dr Tulu provider example:

[research]
provider = "dr-tulu"
model = "dr-tulu"                   # Logical provider model id; currently informational
base_url = "http://localhost:8080/"   # Dr Tulu service base URL; the backend calls /chat
api_key = ""                        # Optional; defaults to RESEARCH_API_KEY / DR_TULU_API_KEY if set
timeout = 1800
poll_interval = 30

Running Dr Tulu locally:

1. Clone and configure dr-tulu separately.
2. In dr-tulu/agent/.env, set at least:
   • SERPER_API_KEY
   • JINA_API_KEY
   • S2_API_KEY (optional but recommended)
3. Start the DR-Tulu model server:

cd /path/to/dr-tulu/agent
conda run -n vllm bash -lc '
  CUDA_VISIBLE_DEVICES=0 \
  vllm serve rl-research/DR-Tulu-8B \
    --port 30001 \
    --dtype auto \
    --max-model-len 16384 \
    --gpu-memory-utilization 0.60 \
    --enforce-eager
'

4. Start the Dr Tulu MCP backend:

cd /path/to/dr-tulu/agent
conda run -n vllm python -m dr_agent.mcp_backend.main --port 8000

5. Start the Dr Tulu app service:

cd /path/to/dr-tulu/agent
conda run -n vllm python workflows/auto_search_sft.py serve \
  --port 8080 \
  --config workflows/auto_search_sft.yaml \
  --config-overrides "search_agent_max_tokens=12000,browse_agent_max_tokens=12000"

6. Point deep-research-mcp at that service:

[research]
provider = "dr-tulu"
base_url = "http://localhost:8080/"
timeout = 1800

The dr-tulu backend calls POST {base_url}/chat, so if you front Dr Tulu behind a different host, port, or reverse proxy, update base_url accordingly.

Perplexity (via Sonar Deep Research and Perplexity's OpenAI-compatible endpoint) provider example:

[research]
provider = "openai"
api_style = "chat_completions"              # Required for Perplexity (no Responses API)
model = "sonar-deep-research"               # Perplexity's Sonar Deep Research
api_key = "ppl-..."                         # Defaults to OPENAI_API_KEY
base_url = "https://api.perplexity.ai"      # Perplexity's OpenAI-compatible endpoint
timeout = 1800

Open Deep Research provider example:

[research]
provider = "open-deep-research"
model = "openai/qwen/qwen3-coder-30b"  # LiteLLM-compatible model id
base_url = "http://localhost:1234/v1"  # LiteLLM-compatible endpoint (local or remote)
api_key = ""                           # Optional if endpoint requires it
timeout = 1800

Ollama (local) provider example:

[research]
provider = "openai"
api_style = "chat_completions"
model = "llama3.1"                     # Any model available in your Ollama instance
base_url = "http://localhost:11434/v1" # Ollama's OpenAI-compatible endpoint
api_key = ""                           # Not required for local Ollama
timeout = 600

llama-server (local llama.cpp server) provider example:

[research]
provider = "openai"
api_style = "chat_completions"
model = "qwen2.5-0.5b"                 # Must match the --alias passed to llama-server
base_url = "http://127.0.0.1:8081/v1"  # llama-server OpenAI-compatible endpoint
api_key = "test"                       # Must match the --api-key passed to llama-server
timeout = 600

Generic OpenAI-compatible Chat Completions provider (Groq, Together AI, vLLM, etc.):

[research]
provider = "openai"
api_style = "chat_completions"
model = "your-model-name"
api_key = "your-api-key"
base_url = "https://api.your-provider.com/v1"
timeout = 600

Optional env variables for Open Deep Research tools:

• SERPAPI_API_KEY or SERPER_API_KEY: enable Google-style search
• HF_TOKEN: optional, logs into Hugging Face Hub for gated models

Install The Included Skill In Claude Code Or Codex

This repository also ships a repo-specific skill guide at skills/deep-research-mcp/SKILL.md.

Installing that file as a local skill gives Claude Code or Codex a focused playbook for this repository's CLI, Python API, providers, and MCP server. It does not install Python dependencies, start the MCP server, or replace the provider configuration in ~/.deep_research. Treat it as complementary to the MCP setup below, not a substitute for it.

Claude Code skill install

Claude Code's skills docs use these locations:

• personal skill: ~/.claude/skills/<skill-name>/SKILL.md
• project skill: .claude/skills/<skill-name>/SKILL.md

Personal install:

mkdir -p ~/.claude/skills/deep-research-mcp
cp /path/to/deep-research-mcp/skills/deep-research-mcp/SKILL.md \
  ~/.claude/skills/deep-research-mcp/SKILL.md

If you prefer to keep the installed skill linked to this checkout:

mkdir -p ~/.claude/skills/deep-research-mcp
ln -sf /path/to/deep-research-mcp/skills/deep-research-mcp/SKILL.md \
  ~/.claude/skills/deep-research-mcp/SKILL.md

Project-local install from the repository root:

mkdir -p .claude/skills/deep-research-mcp
cp skills/deep-research-mcp/SKILL.md .claude/skills/deep-research-mcp/SKILL.md

After that, restart Claude Code or open a new session if the skill does not appear immediately. The skill can be invoked directly as /deep-research-mcp, and Claude can also load it automatically when the task matches the skill description. For a reusable shared extension, package the same skill into a Claude Code plugin instead of copying it by hand.

Official docs:

• Claude Code skills: https://docs.claude.com/en/docs/claude-code/skills
• Claude Code plugins: https://docs.claude.com/en/docs/claude-code/plugins

Codex skill install

Current Codex docs describe skills as skill folders containing SKILL.md, stored globally in $HOME/.agents/skills or repo-locally in .agents/skills.

Personal install:

mkdir -p ~/.agents/skills/deep-research-mcp
cp /path/to/deep-research-mcp/skills/deep-research-mcp/SKILL.md \
  ~/.agents/skills/deep-research-mcp/SKILL.md

Or keep the installed skill linked to this checkout:

mkdir -p ~/.agents/skills/deep-research-mcp
ln -sf /path/to/deep-research-mcp/skills/deep-research-mcp/SKILL.md \
  ~/.agents/skills/deep-research-mcp/SKILL.md

Project-local install from the repository root:

mkdir -p .agents/skills/deep-research-mcp
cp skills/deep-research-mcp/SKILL.md .agents/skills/deep-research-mcp/SKILL.md

If your Codex setup still follows older CLI conventions that use ~/.codex/skills or .codex/skills, mirror the same directory structure there instead.

Codex can invoke the skill implicitly when the task matches its description, or explicitly by mentioning $deep-research-mcp in the prompt. If the skill does not show up immediately, restart Codex.

Official docs:

• Codex skills: https://developers.openai.com/codex/skills
• Codex customization and skill locations: https://developers.openai.com/codex/concepts/customization#skills

Claude Code Integration

1. Configure MCP Server

Choose one of the transports below.

Option A: stdio (recommended when Claude Code should spawn the server itself)

Clone-free user installation:

claude mcp add --scope user --transport stdio deep-research -- \
  uvx --from "git+https://github.com/pminervini/deep-research-mcp.git@main" \
  deep-research-mcp

For a source checkout with provider credentials already stored in ~/.deep_research, use:

claude mcp add deep-research -- uv run --directory /path/to/deep-research-mcp deep-research-mcp

If you want Claude Code to pass OPENAI_API_KEY through to the spawned MCP process explicitly, use:

claude mcp add -e OPENAI_API_KEY="$OPENAI_API_KEY" \
  deep-research -- \
  uv run --directory /path/to/deep-research-mcp deep-research-mcp

Option B: HTTP (recommended when you want to run the server separately)

Start the server in one terminal:

OPENAI_API_KEY="$OPENAI_API_KEY" \
uv run --directory /path/to/deep-research-mcp \
  deep-research-mcp --transport http --host 127.0.0.1 --port 8080

Then add the HTTP MCP server in Claude Code:

claude mcp add --transport http deep-research-http http://127.0.0.1:8080/mcp

Replace /path/to/deep-research-mcp/ with the actual path to your cloned repository. The verified Streamable HTTP endpoint is http://127.0.0.1:8080/mcp.

For multi-hour research, raise Claude Code's tool timeout before launching the CLI and rely on incremental status polls:

export MCP_TOOL_TIMEOUT=14400000  # 4 hours
claude --mcp-config ./.mcp.json

Kick off work with deep_research, note the returned job ID, and call research_status to stream progress without letting any single tool call stagnate.

Output size: Claude Code limits MCP tool output (about 25,000 tokens by default, configurable via MAX_MCP_OUTPUT_TOKENS). The research tools declare the anthropic/maxResultSizeChars annotation so recent Claude Code versions accept large reports without extra configuration; on older versions, raise the limit before launching the CLI:

export MAX_MCP_OUTPUT_TOKENS=50000
claude

Timeout recovery: if a research task exceeds the configured timeout, the server leaves the provider task running by default and returns its task ID; call research_status with that ID to retrieve the full report once it completes. Pass --cancel-on-timeout to deep-research-mcp (or set cancel_on_timeout = true in ~/.deep_research) to restore the old cancel behavior.

2. Use in Claude Code:
   • The research tools will appear in Claude Code's tool palette
   • Simply ask Claude to "research [your topic]" and it will use the Deep Research agent

OpenAI Codex Integration

1. Configure MCP Server

Choose one of the transports below.

Option A: stdio (recommended when Codex should spawn the server itself)

Clone-free installation:

codex mcp add deep-research -- \
  uvx --from "git+https://github.com/pminervini/deep-research-mcp.git@main" \
  deep-research-mcp

For a source checkout, add the MCP server configuration to ~/.codex/config.toml:

[mcp_servers.deep-research]
command = "uv"
args = ["run", "--directory", "/path/to/deep-research-mcp", "deep-research-mcp"]
# If your provider credentials live in shell env vars rather than ~/.deep_research,
# pass them through to the MCP subprocess explicitly:
env_vars = ["OPENAI_API_KEY"]
startup_timeout_ms = 30000  # 30 seconds for server startup
request_timeout_ms = 7200000  # 2 hours for long-running research tasks
# Alternatively, set tool_timeout_sec when using newer Codex clients
# tool_timeout_sec = 14400.0     # 4 hours for deep research runs

Replace /path/to/deep-research-mcp/ with the actual path to your cloned repository.

If your credentials are already configured in ~/.deep_research, env_vars is optional. It is required when you expect the spawned MCP server to inherit OPENAI_API_KEY from the parent shell.

Option B: HTTP (recommended when you want to run the server separately)

Start the server in one terminal:

OPENAI_API_KEY="$OPENAI_API_KEY" \
uv run --directory /path/to/deep-research-mcp \
  deep-research-mcp --transport http --host 127.0.0.1 --port 8080

Then add this to ~/.codex/config.toml:

[mcp_servers.deep-research-http]
url = "http://127.0.0.1:8080/mcp"
tool_timeout_sec = 14400.0

The verified Streamable HTTP endpoint is http://127.0.0.1:8080/mcp.

Important timeout configuration:

• startup_timeout_ms: Time allowed for the MCP server to start (default: 30000ms / 30 seconds)
• request_timeout_ms: Maximum time for research queries to complete (recommended: 7200000ms / 2 hours for comprehensive research)
• tool_timeout_sec: Preferred for newer Codex clients; set this to a large value (e.g., 14400.0 for 4 hours) when you expect long-running research.
• Kick off research once to capture the job ID, then poll research_status so each tool call remains short and avoids hitting client timeouts.

Without proper timeout configuration, long-running research queries may fail with "request timed out" errors.

2. Use in OpenAI Codex:
   • The research tools will be available automatically when you start Codex
   • Ask Codex to "research [your topic]" and it will use the Deep Research MCP server

Gemini CLI Integration

1. Configure MCP Server

Add the MCP server using Gemini CLI's built-in command:

gemini mcp add deep-research -- uv run --directory /path/to/deep-research-mcp deep-research-mcp

Or manually add to your ~/.gemini/settings.json file:

{
  "mcpServers": {
    "deep-research": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/deep-research-mcp", "deep-research-mcp"],
      "env": {
        "RESEARCH_PROVIDER": "gemini",
        "GEMINI_API_KEY": "$GEMINI_API_KEY"
      }
    }
  }
}

Replace /path/to/deep-research-mcp/ with the actual path to your cloned repository.

2. Use in Gemini CLI:
   • Start Gemini CLI with gemini
   • The research tools will be available automatically
   • Ask Gemini to "research [your topic]" and it will use the Deep Research MCP server
   • Use /mcp command to view server status and available tools

HTTP transport: If your Gemini environment supports MCP-over-HTTP, you may run the server with --transport http and configure Gemini with the server URL.

Usage

As a Standalone Python Module

import asyncio
from deep_research_mcp.agent import DeepResearchAgent
from deep_research_mcp.config import ResearchConfig

async def main():
    # Initialize configuration
    config = ResearchConfig.load()
    
    # Create agent
    agent = DeepResearchAgent(config)
    
    # Perform research
    result = await agent.research(
        query="What are the latest advances in quantum computing?",
        system_prompt="Focus on practical applications and recent breakthroughs"
    )
    
    # Print results
    print(f"Report: {result.final_report}")
    print(f"Citations: {result.citations}")
    print(f"Research steps: {result.reasoning_steps}")
    print(f"Execution time: {result.execution_time:.2f}s")

# Run the research
asyncio.run(main())

As an MCP Server

Two transports are supported: stdio (default) and HTTP streaming.

# 1) stdio (default) — for editors/CLIs that spawn a local process
uv run deep-research-mcp

# 2) HTTP streaming — start a local HTTP MCP server
uv run deep-research-mcp --transport http --host 127.0.0.1 --port 8080

Notes:

• HTTP mode uses streaming responses provided by FastMCP. The tools in this server return their full results when a research task completes; streaming is still beneficial for compatible clients and for future incremental outputs.
• The verified Streamable HTTP endpoint is /mcp, so the default local URL is http://127.0.0.1:8080/mcp.
• If you start the server outside the client and rely on environment variables for credentials, export them before launching the server process. If you use stdio and let the client spawn the server, make sure the client passes the required env vars through.

OAuth authentication for HTTP

HTTP OAuth is opt-in. Set both variables below before starting the server:

export MCP_AUTH_ISSUER_URL="https://firm-mermaid-02-staging.authkit.app"
export MCP_AUTH_RESOURCE_URL="http://127.0.0.1:8080/mcp"

uv run deep-research-mcp --transport http --host 127.0.0.1 --port 8080

MCP_AUTH_RESOURCE_URL must exactly match the Resource Indicator configured in WorkOS, including the /mcp path. When enabled, the server verifies each AuthKit access token's signature, issuer, expiration, and audience and publishes RFC 9728 protected-resource metadata for MCP clients. No WorkOS API key or client secret is required by the server. Local stdio usage is unchanged.

In WorkOS, enable Client ID Metadata Documents (CIMD), keep Dynamic Client Registration (DCR) enabled for older clients, and add the resource URL under Connect → Configuration. See the WorkOS MCP authentication guide.

Command-Line Interface

The installed deep-research-cli command provides direct access to all research functionality from the terminal. Its implementation lives in src/deep_research_mcp/cli.py, while cli/deep-research-cli.py remains a source-checkout compatibility wrapper. It supports two modes of operation: agent mode (default) which runs DeepResearchAgent directly, and MCP client mode which connects to a running MCP server over HTTP.

Configuration is loaded from ~/.deep_research by default. Every ResearchConfig parameter can be overridden via CLI flags, which take precedence over both the TOML file and environment variables.

Terminal UI

The repository also ships with a full-screen terminal UI at cli/deep-research-tui.py. It presents the same core functionality as the CLI in a dark, keyboard-driven interface for running deep research, task status checks, and saving output to disk.

The TUI features a split-panel layout:

• Left panel: Configuration controls for mode selection (Agent/MCP), provider settings, model configuration, query input, and system prompt
• Right panel: Output display showing research results or status information

The animation above demonstrates the TUI workflow: loading a research query, running it through a local Dr Tulu-compatible demo endpoint, viewing the result in the output panel, and saving the output to a file.

Quick Start

# Start in direct agent mode
uv run python cli/deep-research-tui.py

# Start in MCP client mode
uv run python cli/deep-research-tui.py --mode mcp \
  --server-url http://127.0.0.1:8080/mcp

# Start with Gemini selected
uv run python cli/deep-research-tui.py --provider gemini

TUI Workflow

• Use the left control panel to edit provider settings, query text, system prompt, and save path.
• The TUI starts focused on the Mode selector rather than inside the query editor.
• Use Tab / Shift+Tab to move through all controls.
• Use Up / Down to move between non-editor controls, including single-line inputs.
• Use Left / Right to toggle booleans and cycle through choice fields when a Switch or Select has focus.
• Press Enter to activate buttons, toggle switches, cycle selects, or move forward from a single-line input.
• TextArea widgets such as Query and System Prompt keep normal cursor-key editing behavior.
• Use r to run deep research, t to check task status, s to save the current output, and q to quit.
• The right panel shows the latest research report or status response.

Provider Defaults

In agent mode, the TUI applies provider-aware defaults:

• openai + responses: model gpt-5.6-sol, base URL https://api.openai.com/v1
• openai + chat_completions: model gpt-5-mini, base URL https://api.openai.com/v1
• openai-codex: model auto, fixed base URL https://chatgpt.com/backend-api/codex
• dr-tulu: model dr-tulu, base URL http://localhost:8080/
• gemini: model deep-research-preview-04-2026, base URL https://generativelanguage.googleapis.com
• open-deep-research: model openai/qwen/qwen3-coder-30b, base URL http://localhost:1234/v1

Switching provider or OpenAI API style automatically refreshes the model and base URL defaults. You can still override those fields manually afterward.

Research and Saving Output

• Run Deep Research executes either the direct agent flow or the MCP client flow, depending on the selected mode.
• Save Output writes the current contents of the output panel to the configured path, creating parent directories if needed.

Notes

• In mcp mode, set MCP Server URL to a running Streamable HTTP endpoint such as http://127.0.0.1:8080/mcp.
• The TUI reuses the same config-loading behavior as deep-research-cli, so ~/.deep_research and any startup overrides still apply.
• Direct-agent JSON rendering is available through the JSON Output toggle; MCP mode saves the textual tool response exactly as returned by the server.
• The current layout is designed for terminals at least 100 columns wide and 28 rows tall.

Quick Start

Gemini Deep Research:

uv run deep-research-cli \
  --provider gemini \
  --model deep-research-preview-04-2026 \
  --base-url https://generativelanguage.googleapis.com \

Tested local OpenAI-compatible backends

The unified CLI works with local servers that expose an OpenAI-compatible Chat Completions API. The commands below were tested against local Ollama and local llama-server (from llama.cpp).

Ollama

Basic research flow:

uv run deep-research-cli \
  --provider openai \
  --api-style chat_completions \
  --base-url http://localhost:11434/v1 \
  --api-key test \
  --model qwen3.5:0.8b \
  --timeout 180 \
  research "Reply with exactly: ok"

Observed output:

HTTP Request: POST http://localhost:11434/v1/chat/completions "HTTP/1.1 200 OK"

ok

llama-server

Start a local OpenAI-compatible server and let it download a small GGUF model from Hugging Face automatically:

llama-server \
  --host 127.0.0.1 \
  --port 8081 \
  --api-key test \
  --ctx-size 4096 \
  --alias qwen2.5-0.5b \
  -hf Qwen/Qwen2.5-0.5B-Instruct-GGUF:Q4_K_M

Then point the CLI at the server:

uv run deep-research-cli \
  --provider openai \
  --api-style chat_completions \
  --base-url http://127.0.0.1:8081/v1 \
  --api-key test \
  --model qwen2.5-0.5b \
  --timeout 120 \
  research "Reply with exactly: ok"

Observed output:

HTTP Request: POST http://127.0.0.1:8081/v1/chat/completions "HTTP/1.1 200 OK"

research QUERY --server-url URL -- use MCP client mode.

Instead of running the agent directly, connect to a running Deep Research MCP server over Streamable HTTP.

# First, start the MCP server in another terminal:
uv run deep-research-mcp --transport http --host 127.0.0.1 --port 8080

# Then run queries against it:
uv run deep-research-cli research "AI trends" \
  --server-url http://127.0.0.1:8080/mcp

status TASK_ID -- check the status of a running research task.

# Agent mode
uv run deep-research-cli status abc123-def456-ghi789

# MCP client mode
uv run deep-research-cli status abc123-def456-ghi789 \
  --server-url http://127.0.0.1:8080/mcp

config -- display the resolved configuration.

Shows the final configuration after merging the TOML file, environment variables, and any CLI overrides.

# JSON output (default), with secrets masked
uv run deep-research-cli config

# Human-readable output
uv run deep-research-cli config --pretty

# Show full API keys
uv run deep-research-cli config --pretty --show-secrets

# See the effect of CLI overrides
uv run deep-research-cli --provider gemini --timeout 600 config --pretty

# Skip config validation
uv run deep-research-cli config --no-validate

auth {login,status,logout} -- manage the independent OpenAI Codex subscription session.

uv run deep-research-cli auth login
uv run deep-research-cli auth status
uv run deep-research-cli auth logout

Configuration Overrides

All global flags are placed before the subcommand and override the corresponding ResearchConfig field:

Configuration precedence (highest to lowest): CLI flags > environment variables > TOML config file (~/.deep_research) > built-in defaults.

  • callback_url: optional webhook notified when research completes
  • Returns: Dictionary with final report, citations, and metadata

• get_task_status(task_id)

  • Check the status of a research task
  • Returns: Task status information

ResearchConfig

Configuration class for the research agent.

Parameters

• provider: Research provider (openai, openai-codex, dr-tulu, gemini, or open-deep-research; default: openai)
• api_style: API style for the openai provider (responses or chat_completions; default: responses). Ignored for openai-codex, dr-tulu, gemini, and open-deep-research.
• model: Model identifier
  • OpenAI: Responses model (e.g., gpt-5-mini)
  • OpenAI Codex subscription: auto (default) or an account catalogue slug
  • Dr Tulu: logical provider id (default: dr-tulu)
  • Gemini: Deep Research agent id (for example deep-research-preview-04-2026)
  • Open Deep Research: LiteLLM model id (e.g., openai/qwen/qwen3-coder-30b)
• api_key: API key for the configured endpoint (optional). Defaults to env OPENAI_API_KEY for openai, DR_TULU_API_KEY for dr-tulu, GEMINI_API_KEY / GOOGLE_API_KEY for gemini. Ignored for openai-codex.
• base_url: Provider API base URL (optional). Defaults to https://api.openai.com/v1 for openai, the fixed https://chatgpt.com/backend-api/codex endpoint for openai-codex, http://localhost:8080/ for dr-tulu, https://generativelanguage.googleapis.com for gemini, and http://localhost:1234/v1 for open-deep-research.
• timeout: Maximum time for research in seconds (default: 1800)
• poll_interval: Polling interval in seconds (default: 30)

Development

Running Tests

# Install dev dependencies
uv sync --extra dev

# Run all tests
uv run pytest -v

# Run with coverage
uv run pytest --cov=deep_research_mcp tests/

# Run specific test file
uv run pytest tests/test_agents.py

When ~/.deep_research_auth.json contains a current or refreshable openai-codex session, a normal uv run pytest tests/ run automatically executes the live Codex end-to-end test and consumes subscription allowance. Without that session, the test is skipped. Use -m "not api" to exclude all live provider tests explicitly.
