Pinax

Claude Desktop

Wire Pinax into Anthropic's official Claude Desktop client.

Claude Desktop reads MCP servers from a JSON config file. On macOS:

~/Library/Application Support/Claude/claude_desktop_config.json

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

1. Index a docs site

pinax add stripe

2. Add the server entry

{
  "mcpServers": {
    "pinax": {
      "command": "pinax",
      "args": ["serve"],
    },
  },
}

A single pinax serve covers every manifest you’ve added. To pin a single docs site:

{
  "mcpServers": {
    "stripe-docs": {
      "command": "pinax",
      "args": ["serve", "stripe"],
    },
  },
}

Or let Pinax write the snippet for you:

pinax config claude            # prints the unified snippet
pinax config claude --split    # one entry per manifest

3. Restart Claude Desktop

Quit and relaunch - the app only reads the config file at startup. You should see a small plug icon in the conversation header confirming the server is connected.

4. Try it

Ask Claude something only the docs would know:

Using the pinax tools, find the Stripe API method for confirming a PaymentIntent and quote its required parameters.

Claude will call list_sections → search_pages → get_page and answer from the live page.

Troubleshooting

  • “Failed to load tools” in the Claude UI usually means pinax isn’t on the PATH the desktop app inherits. Use an absolute path in command (the output of which pinax).
  • No tools listed at all - quit Claude Desktop fully (Cmd-Q on macOS, not just close the window) and relaunch.
  • For deeper debugging, run pinax serve --http in a terminal and watch the log UI at http://localhost:8423/ while Claude makes calls.
