- Fetches the latest Node.js API documentation.
- Provides node-search tool to find modules or list methods.
- Provides node-list tool to summarize all available modules.
- Logs activity and errors to /tmp/mcp-server-nodejs-docs.log.
- Connects to MCP clients via stdio (e.g., Cursor, Qodo AI).
Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
MCP Server for Node.js API DocumentationCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Install dependencies with npm install, then start the server with npm run start. The server listens over stdio and provides tools like node-search and node-list. To enable debug logging, start with node index.js --debug.
Claude Desktop / Cursor
Paste into your MCP client config file to install this server.

}MCP Server for Node.js API Documentation
This project implements a Model Context Protocol (MCP) server that provides access to the official Node.js API documentation. It fetches the documentation from nodejs.org and exposes it through MCP tools.
Features
Fetches the latest Node.js API documentation.
Provides MCP tools to query documentation for specific modules, classes, or methods.
Offers a search tool (node-search) to find modules or list all available modules with their methods.
Offers a list tool (node-list) to get a summary of all available modules.
Logs activity and errors to /tmp/mcp-server-nodejs-docs.log using pino.
Installation
1. Clone the repository (if applicable):
git clone <repository_url>
cd <repository_directory>
2. Install dependencies:
This project requires Node.js and npm.
npm install
Usage
To start the MCP server, run the following command in your terminal:
npm run start
The server will initialize, fetch the documentation, create the necessary tools, and then listen for connections over standard input/output (stdio).
To enable debug logging, start the server with the --debug flag:
node index.js --debug
Debugging
The server logs detailed information about its operations, including fetches, tool executions, and errors, to the following file:
/tmp/mcp-server-nodejs-docs.log
You can monitor this file to debug issues:
tail -f /tmp/mcp-server-nodejs-docs.log
Testing with MCP Inspector
Use the built-in debug script:
npm run debug
Or directly via npx:
npx -y @modelcontextprotocol/inspector node index.js
Connecting to MCP Clients
This server communicates over standard input/output (stdio). To connect it to MCP clients like Cursor or Qodo AI, you need to configure the client to launch the server using its command.
Example Configuration (Conceptual):
Most clients will have a settings area where you can add custom MCP servers. You'll typically need to provide:
1. A Name: e.g., "Node.js API Documentation"
2. The Command: The command to execute the server. Make sure to provide the absolute path to node and the index.js file, or ensure node is in the PATH environment variable accessible by the client.
# Example - replace with your actual absolute paths
/path/to/your/node /path/to/your/project/index.js
Finding Node Path: Run which node in your terminal.
* Finding Project Path: Navigate to the project directory and run pwd.
Refer to your specific MCP client's documentation for the exact steps on adding a stdio-based server.
Example using Cursor:
1. Go to Settings -> Cursor Settings -> MCP Servers.
2. Click Add Server.
3. Enter a name (e.g., "NodeJS API Documentation").
4. In the Command field, enter the full command, like: /Users/youruser/.nvm/versions/node/v20.11.1/bin/node /Users/youruser/projects/mcp-server-nodejs-docs/index.js (replace paths with your actual paths).
5. Save the server configuration.
6. You should now be able to use the @NodeJS API Documentation tag (or whatever name you chose) in your chat prompts.
