FAQ

Questions

A production-grade Model Context Protocol (MCP) server for the Code-Fundi API: a codebase map and blast-radius engine for AI coding agents. Enables any MCP-compatible AI assistant (Claude, Claude Code, Cursor, Windsurf, VS Code Copilot, and more) to search, research, index, and scan code repositories through natural language, and see what a change breaks before it ships.

Built with FastMCP (TypeScript) and Zod for schema validation.

Getting started for AI agents

If you are an AI agent (or configuring one) and no CODEFUNDI_API_KEY is set, you must self-authenticate before using search, repos, chat, or other authenticated tools. The auth tools (code-fundi-auth-*) work without a pre-existing key.

Which path to use

Situation	Action
`CODEFUNDI_API_KEY` is set in MCP config	Use any tool immediately — the server sends it as `X-API-Key` on every request
No API key configured	Run the OTP self-auth flow below (recommended) or password sign-in

Zero-config MCP setup (no API key)

You can start the MCP server without CODEFUNDI_API_KEY and authenticate at runtime:

{
  "mcpServers": {
    "code-fundi": {
      "command": "npx",
      "args": ["-y", "@codefundi/code-fundi-mcp"]
    }
  }
}

Self-authenticate with OTP (recommended)

Code-Fundi uses Supabase-backed auth (POST /v2/auth/authenticate, /v2/auth/verify, /v2/auth/resend). OTP emails contain a 6-digit code — magic links are not supported on this path.

Ask the human user for their email address.
Call code-fundi-auth-authenticate with:
- auth_mode: "otp"
- email: the user's email
- should_create_user: true for a new account, false for a returning user
Tell the user to check their inbox for a 6-digit code. The API may return verification_required: true and api_key.key_state: "agent_pending" until verification completes.
Ask the user for the 6-digit OTP (human-in-the-loop — you cannot guess or bypass this step).
Call code-fundi-auth-verify with the same email and the token (6 digits).
On success, the MCP server automatically configures the API key in memory for all subsequent tool calls in this session.

If the code expired or was not received, call code-fundi-auth-resend with the same email, then repeat step 5.

Example dialogue:

Agent: What email should I use to sign in to Code-Fundi?
User:  [email protected]
Agent: [calls code-fundi-auth-authenticate] I've sent a 6-digit code to [email protected]. Please paste it here.
User:  482913
Agent: [calls code-fundi-auth-verify] You're signed in. I can now search and index your repositories.

Password sign-in (alternative)

For existing accounts with a password, call code-fundi-auth-authenticate with auth_mode: "password", the user's email, should_create_user: false, and the password parameter. The MCP client sends the password only in the X-CodeFundi-Auth-Password header (never in the JSON body). Production requires HTTPS. Returning users may receive an active API key immediately without a separate verify step.

After authentication

The API key is held in memory for the lifetime of the MCP server process. It is not persisted across IDE or MCP restarts.
Recommend the user add the key to their MCP config as CODEFUNDI_API_KEY so future sessions start authenticated.
A FREE-tier account and API key are created automatically on first signup.

Errors

HTTP status	What to do
401 Unauthorized	No valid key — run the OTP flow above, or set `CODEFUNDI_API_KEY`
429 Too many requests	Auth endpoints are rate-limited per IP; wait for `Retry-After` seconds, then retry

Quick Start

Install from npm (recommended)

Install the package (includes a pre-built dist/). The code-fundi-mcp binary is on your PATH when installed globally, or available via npx without cloning the repo:

npm install -g @codefundi/code-fundi-mcp

Or add it to a project:

npm install @codefundi/code-fundi-mcp

Install from source (this repository)

git clone https://github.com/Code-Fundi/code-fundi-mcp.git
cd code-fundi-mcp
npm install
npm run build

Configure

Option A — API key (fastest): set your key as an environment variable:

export CODEFUNDI_API_KEY=your_api_key_here

Option B — no API key: skip the env var and let the agent self-authenticate at runtime. See Getting started for AI agents.

Zero-config MCP example (no env block):

{
  "mcpServers": {
    "code-fundi": {
      "command": "npx",
      "args": ["-y", "@codefundi/code-fundi-mcp"]
    }
  }
}

Use with Claude Desktop

After a global install (npm i -g @codefundi/code-fundi-mcp), point MCP at the published binary (no path to dist/index.js required):

{
  "mcpServers": {
    "code-fundi": {
      "command": "@codefundi/code-fundi-mcp",
      "env": {
        "CODEFUNDI_API_KEY": "your_api_key_here"
      }
    }
  }
}

If the binary is not on your PATH, use npx (downloads or uses the local package and runs the same entrypoint):

{
  "mcpServers": {
    "code-fundi": {
      "command": "npx",
      "args": ["-y", "@codefundi/code-fundi-mcp"],
      "env": {
        "CODEFUNDI_API_KEY": "your_api_key_here"
      }
    }
  }
}

Use with Cursor

Same pattern as Claude: command plus optional args only, no manual path to the repo:

{
  "mcpServers": {
    "code-fundi": {
      "command": "npx",
      "args": ["-y", "@codefundi/code-fundi-mcp"],
      "env": {
        "CODEFUNDI_API_KEY": "your_api_key_here"
      }
    }
  }
}

When developing inside this repo, you can run npm run dev or npx tsx src/index.ts without building first.

Development Mode

npm run dev                          # Run with tsx (no build needed)
npx fastmcp inspect src/index.ts    # Open MCP Inspector UI
npx fastmcp dev src/index.ts        # Test with MCP CLI
