HackMD MCP Server

This is a Model Context Protocol (MCP) server for interacting with the HackMD API. It allows AI assistants to perform operations such as:

• Get user information
• List user's notes
• Create, read, update, and delete notes
• View read history
• Work with team notes

Requirements

• Node.js 18+

Environment Variables

• HACKMD_API_TOKEN: [Required] Your HackMD API token
• HACKMD_API_URL: (Optional) HackMD API Endpoint URL. Default: https://api.hackmd.io/v1

You can get an API token from HackMD settings.

Install to Claude Desktop (or other MCP clients)

Example Usage

Can you help me manage my HackMD notes?

Then use commands like:

Please list all my notes.

Local Development

This project uses Bun as its package manager. You should install it if you haven't already.

Clone the repository and install dependencies:

git clone https://github.com/yuna0x0/hackmd-mcp.git
cd hackmd-mcp
bun install

Configuration

1. Create a .env file by copying the example:

cp .env.example .env

2. Edit the .env file and add your HackMD API token:

HACKMD_API_TOKEN=your_api_token

Debugging with MCP Inspector

You can use the MCP Inspector to test and debug the HackMD MCP server:

npx @modelcontextprotocol/inspector -e HACKMD_API_TOKEN=your_api_token npx hackmd-mcp

# Use this instead when Local Development
bun run inspector

Then open your browser to the provided URL (usually http://localhost:5173) to access the MCP Inspector interface. From there, you can:

1. Connect to your running HackMD MCP server
2. Browse available tools
3. Run tools with custom parameters
4. View the responses

This is particularly useful for testing your setup before connecting it to Claude or another AI assistant.
