ApexVol MCP Server

A Model Context Protocol (MCP) server that gives AI assistants live access to ApexVol's options analytics platform: options chains, IV rank, volatility risk premium, Greeks, gamma exposure (GEX), expected moves, strategy building, and market screening. 44 tools, one connector.

Works with Claude Code, Claude Desktop, claude.ai (remote connector — no install), and any MCP-compatible client.

• Setup guide (step by step): https://apexvol.com/learn/claude-options-data-mcp
• REST API docs: https://apexvol.com/docs/api
• Single-file API reference, sized for LLM context windows: https://apexvol.com/docs/api/apexvol-api.md

Quickstart

Option A — Remote connector (no install)

Add a custom connector in claude.ai or Claude Desktop (Settings → Connectors → Add custom connector) with this URL:

https://apexvol.com/mcp-server

Sign in with your ApexVol account when prompted (OAuth). That's it — no Python, no config files.

Claude Code can use the remote server too:

claude mcp add --transport http apexvol https://apexvol.com/mcp-server

then authenticate when prompted (the /mcp command shows login state).

Option B — Local install (stdio)

pipx install apexvol-mcp
claude mcp add apexvol -e APEXVOL_API_TOKEN=avmcp_YOUR_TOKEN_HERE -- apexvol-mcp

Access requires any paid ApexVol plan (from $55/mo). Every tool returns the same data tier your web plan includes; Pro unlocks the full toolset. Tokens are self-served at apexvol.com/account → API Access.

Example session

Real output, 2026-08-15:

You: What's the IV rank for SPY?

Claude calls get_iv_rank("SPY"):

Metric	Value
Current IV	12.3%
IV Rank	7.8
IV Percentile	8.3%
52-Week Low	11.2%
52-Week High	25.0%

Assessment: LOW — consider buying premium rather than selling it.

Follow-ups like "so is a calendar spread better than an iron condor here?" work because Claude can pull the term structure, build both strategies, and compare the Greeks — in the same conversation.

The local server runs on your machine and calls the ApexVol platform API. The remote server is the same toolset hosted by ApexVol, authenticated with OAuth instead of a token.

Features

• 43 Analytics Tools — every /api/mcp/data endpoint is reachable from Claude
• Built-in reference — a help tool answers "which tool gives me X" from a bundled copy of the API docs, and 41 prompts appear in your client's prompt picker: 33 starters, three per data family, plus 8 whole-job recipes
• Natural Language Interface - Ask questions like "What's the IV rank for SPY?"
• Remote or local - hosted OAuth connector, or a pipx-installed stdio server
• Token Authentication - Secure API token validation (local mode)
• Built-in health check - apexvol-mcp --check verifies your install and token

Help and discovery (1 tool)

• help - The API reference inside the server. help() lists the families and how to ask; help("get_iv_rank"), help("gex") or help("/iv-rank/{ticker}") return the tool, family or endpoint record (question, parameters, units, basis, fields, plan, prompts, docs URL); any other words run a search. Bundled data, no request cost, works before a token is set.

Prompt starters

The server also registers 41 prompts, three per data family plus one per recipe, that show up in the prompt picker of Claude Desktop, Cursor and VS Code. Each one carries the ticker as an argument with a real default, names the tools that answer it and links the family page. The wording matches the prompt library.

Installation (local mode, in detail)

Prerequisites

• Python 3.10+
• Any paid ApexVol plan and an API token (see "Getting a Token" below)

Install the Package

We recommend pipx so the apexvol-mcp command is isolated and always on your PATH:

pipx install apexvol-mcp

Plain pip install apexvol-mcp also works.

Or install from source:

git clone https://github.com/ryansilk/apexvol-mcp.git
cd apexvol-mcp
pip install -e .

Verify the install

Before touching any Claude config, confirm the command works and your token authenticates:

APEXVOL_API_TOKEN=avmcp_YOUR_TOKEN_HERE apexvol-mcp --check

--check prints the client version, auth result, and your remaining rate-limit/monthly budget. If it says OK, the only step left is wiring it into Claude.

Configuration

Claude Code (CLI)

One command:

claude mcp add apexvol -e APEXVOL_API_TOKEN=avmcp_YOUR_TOKEN_HERE -- apexvol-mcp

Or add to your project's .mcp.json or global ~/.claude.json by hand:

{
  "mcpServers": {
    "apexvol": {
      "command": "apexvol-mcp",
      "env": {
        "APEXVOL_API_TOKEN": "avmcp_YOUR_TOKEN_HERE"
      }
    }
  }
}

Claude Desktop App

macOS: Edit ~/Library/Application Support/Claude/claude_desktop_config.json

Windows: Edit %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "apexvol": {
      "command": "apexvol-mcp",
      "env": {
        "APEXVOL_API_TOKEN": "avmcp_YOUR_TOKEN_HERE"
      }
    }
  }
}

(Claude Desktop also supports the remote connector under Settings → Connectors — see Quickstart Option A.)

Environment Variables

Rate limits

60 requests/min, 1,000/hour, 10,000/month per account — shared across local and remote modes. apexvol-mcp --check shows your remaining budget.

Usage

After configuration, restart Claude Code or Claude Desktop to load the MCP server.

Agent Skill

The repo ships an Agent Skill that teaches an AI assistant how to combine these tools into complete analyses — rich/cheap volatility assessment, earnings setups, premium-selling screens, GEX regime reads, and strategy stress-testing — with interpretation thresholds and error handling.

To use it with Claude Code, copy the skill into your skills directory:

mkdir -p ~/.claude/skills/options-analysis
curl -o ~/.claude/skills/options-analysis/SKILL.md \
  https://raw.githubusercontent.com/ryansilk/apexvol-mcp/main/skills/options-analysis/SKILL.md

Claude then loads it automatically whenever an options-analysis question comes up (the MCP server itself must also be connected).

Response Format

All tools return structured data with a markdown summary:

{
  "success": true,
  "data": { ... },
  "summary": "## AAPL IV Analysis\n\n| Metric | Value |\n...",
  "metadata": {
    "timestamp": "2025-01-08T10:30:00",
    "ticker": "AAPL"
  }
}

Authentication

Local mode uses token-based authentication; the remote connector uses OAuth (sign in with your ApexVol account, no token handling at all).

Token Format

• Prefix: avmcp_
• Length: 38 characters total

Getting a Token

API and MCP access are included with every paid ApexVol plan (Basic $55/mo, Premium, Pro). Each tool returns the same data tier your web plan includes; Pro unlocks the full toolset.

1. Create and manage tokens at apexvol.com/account → API Access — issuance, rotation, and revocation are all self-service.
2. Questions or issues: support@apexvol.com.

The token is sent with every request, so treat it like a password. If it leaks, revoke it on the account page and create a new one.

Troubleshooting

Start with the health check — it diagnoses most issues in one shot:

APEXVOL_API_TOKEN=avmcp_YOUR_TOKEN_HERE apexvol-mcp --check

"Invalid or missing API token"

• Verify your APEXVOL_API_TOKEN environment variable is set correctly
• Ensure your token hasn't been revoked (check apexvol.com/account → API Access)
• Check that the token starts with avmcp_

"Request timed out"

• Check your internet connection
• The ApexVol platform may be temporarily unavailable

MCP Server Not Loading

• Restart Claude Code/Desktop after configuration changes
• Check that apexvol-mcp is in your PATH (which apexvol-mcp; pipx installs handle this automatically)
• Verify the configuration JSON syntax is valid

Remote connector won't authorize

• Confirm your ApexVol account has an active paid plan, then remove and re-add the connector
• The connector URL is exactly https://apexvol.com/mcp-server (no trailing slash)
