In-depth architectural comparison of the Claude MCP Bridge and Stellify MCP MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Claude MCP Bridge
Coding Agents · Local stdio
Quality: 64/100 (Good) | Auth: other
Stellify MCP
Coding Agents · Remote HTTP/SSE
Quality: 51/100 (Good) | Auth: No auth required
Verdict Summary: Choose Claude MCP Bridge if you need specialized Coding Agents tools running via a local process. Choose Stellify MCP if your workspace requires Coding Agents integration with remote web transport. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Claude MCP Bridge when:
You need dedicated capabilities in the Coding Agents domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: other (BYOK (Pay Provider Direct)).
Execute a prompt via Claude Code CLI with optional file context and session resume. Claude is an AI coding agent that can generate, analyze, refactor, and explain code.
Capabilities: code generation and refactoring, code analysis and explanation, file understanding (text and images), multi-turn conversations via sessionId.
Cost: Default model is Sonnet (~$0.01-0.10/call). Use effort="low" for simple tasks, effort="high" + model="opus" for complex analysis. Set maxBudgetUsd to cap per-call cost (recommended for effort="max" or model="opus").
Tips:
- Set workingDirectory to the target repo for project-aware responses.
- Break complex tasks into focused prompts rather than one large request.
- Resume multi-turn conversations with sessionId from a previous response's metadata.
- Include relevant files via the files parameter for targeted context (text files inlined in prompt, images trigger allowed-tools mode).
- Use noSessionPersistence=true for stateless one-shot calls.
structured
Generate JSON conforming to a provided JSON Schema. Uses Claude CLI's native --json-schema flag for validated output (not client-side validation).
Use for: data extraction from text/files, classification, entity parsing, or any task needing machine-parseable output.
Cost: Similar to query (~$0.01-0.10/call). Schema complexity doesn't significantly affect cost.
Tips:
- Pass the JSON Schema as a JSON string in the schema parameter.
- Schema max size: 20KB. Keep schemas focused for reliable output.
- For extraction tasks, include source text via the files parameter or inline in the prompt.

Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Claude MCP Bridge is categorized under Coding Agents and uses a local stdio subprocess. In contrast, Stellify MCP belongs to Coding Agents using remote streaming HTTP/SSE transport. Select Claude MCP Bridge when you need capabilities focused on coding agents and Stellify MCP when you require tools for coding agents.
Web search via Claude Code CLI using WebSearch and WebFetch tools. Searches the web and synthesizes a comprehensive answer with source URLs.
Use for: current information, documentation lookups, API references, comparing libraries, and research questions.
Cost: Typically ~$0.02-0.05/search with Sonnet.
Tips:
- Ask specific, focused questions for best results.
- Results include source URLs for verification.
- Use maxResponseLength to control response verbosity.
- Increase timeout for complex research queries that may require multiple web fetches.
listSessions
List active Claude CLI sessions tracked by this server. Returns session metadata (IDs, models, timing, turn counts, cumulative cost) for orchestration. Use to check available sessions before resuming with sessionId. No cost (local lookup only).
ping
Health check: verifies Claude CLI is installed and authenticated, reports versions, capabilities, and configuration. No cost (local check only).
Stellify MCP Tools (32)
get_project
Get the active Stellify project for the authenticated user. **Call this first before any other operations.**
get_directory
Get a directory by UUID to see its contents.
create_directory
Create a new directory for organizing files.
create_file
Create a new file in a Stellify project. This creates an empty file shell - no methods, statements, or template yet.
get_file
Get a file by UUID with all its metadata, methods, and statements.
save_file
Save/update a file with its full configuration. This finalizes the file after `create_file`.
search_files
Search for files in the project by name or type.
create_method
Create a method signature in a file (without implementation).
add_method_body
Parse and add code to a method body. Stellify parses the code into structured JSON statements.
search_methods
Search for methods in the project by name or within a specific file.
create_statement
Create an empty statement in a file. This is step 1 of 2 - you must call `add_statement_code` next.
add_statement_code
Add code to an existing statement. This is step 2 of 2 - call after `create_statement`.
