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+
HackMD API token

Installation

Clone the repository and install dependencies:

git clone https://github.com/yuna0x0/hackmd-mcp.git
cd hackmd-mcp
bun install  # or use npm, yarn, pnpm

Configuration

Option 1: Using a .env file

Create a .env file by copying the example:
```
cp .env.example .env
```
Edit the .env file and add your HackMD API token:
```
HACKMD_API_TOKEN=your_api_token
```

Option 2: Using environment variables inline

You can also provide the API token directly when running the server:

HACKMD_API_TOKEN=your_api_token bun start

You can get an API token from HackMD settings.

Usage

Start the MCP server

Local installation:

bun start  # or use npm, yarn, pnpm

Using bunx (without cloning):

HACKMD_API_TOKEN=your_api_token bunx hackmd-mcp

Debugging with MCP Inspector

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

# Using the package.json script
bun run inspector  # or use npm, yarn, pnpm

# Alternative: Direct use with bunx (or npx)
bunx @modelcontextprotocol/inspector -e HACKMD_API_TOKEN=your_api_token bunx hackmd-mcp

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

Connect to your running HackMD MCP server
Browse available tools
Run tools with custom parameters
View the responses

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