Auggie MCP Server

Minimal MCP server exposing Auggie CLI as tools for Q&A and code implementation.

Tools

• ask_question: Repository Q&A via Auggie’s context engine.
• implement: Implement a change in the repo; dry-run by default.

Requirements

• Node.js 18+
• Python 3.10+ available on the system (used internally; no manual setup needed)
• Auggie CLI installed (check by running auggie --version) - _see installation guide_

Authentication (AUGMENT_API_TOKEN)

Retrieve your token via the Auggie CLI:

# Ensure Auggie CLI is installed and on PATH
auggie --version

# Sign in (opens browser flow)
auggie login

# Print your token
auggie --print-augment-token

Provide the token in either of these ways:

• Cursor/Claude config (recommended): set it under env for the server

{
  "mcpServers": {
    "auggie-mcp": {
      "command": "npx",
      "args": ["-y", "auggie-mcp@latest"],
      "env": { "AUGMENT_API_TOKEN": "YOUR_TOKEN" }
    }
  }
}

• Shell environment (macOS/Linux)

One-off for a single command:

AUGMENT_API_TOKEN=YOUR_TOKEN npx -y auggie-mcp --setup-only

Persist for future shells (zsh):

echo 'export AUGMENT_API_TOKEN=YOUR_TOKEN' >> ~/.zshrc
source ~/.zshrc

Security tip: never commit tokens to source control. Prefer per-machine environment variables or your client's secure config store.

Configure Clients

Cursor via npx

Use this MCP config in Cursor (global or per-project):

{
  "mcpServers": {
    "auggie-mcp": {
      "command": "npx",
      "args": ["-y", "auggie-mcp@latest"],
      "env": { "AUGMENT_API_TOKEN": "YOUR_TOKEN" }
    }
  }
}

This will:

• download the wrapper package,
• create a local Python venv inside the package,
• install requirements.txt, and
• launch the Python server in stdio mode.

Quick test via npx (terminal)

# Install deps into the package's local venv (no global installs)
npx -y auggie-mcp --setup-only

# Run the server (stdio). Useful for quick smoke-tests.
npx -y auggie-mcp

# Optional: start HTTP mode for manual debugging
npx -y auggie-mcp -- --http

Claude Desktop (macOS)

Edit ~/Library/Application Support/Claude/claude_desktop_config.json and add:

{
  "mcpServers": {
    "auggie-mcp": {
      "command": "npx",
      "args": ["-y", "auggie-mcp@latest"],
      "env": { "AUGMENT_API_TOKEN": "YOUR_TOKEN" }
    }
  }
}

Security and permissions

• Default: implement runs in dry‑run mode. No files are written, no shell runs; you get a proposed diff.
• Enable writes: set dry_run: false.
• Recommendation: use a feature branch and review the diff before merging.
