Linear MCP Server

A Model Context Protocol (MCP) server for Linear, providing AI assistants with access to Linear's project management capabilities.

Features

• Resources: Access issues, projects, teams, users, roadmaps, documents, initiatives, and more
• Tools: Create and update issues, manage projects, search, link projects to initiatives
• Prompts: Templates for issue creation, bug reports, feature requests, and more

Setup

Prerequisites

• Node.js 18 or later
• A Linear API key

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/linear-mcp.git
   cd linear-mcp

2. Install dependencies:

   npm install

3. Create a .env file with your Linear API key:

   LINEAR_API_KEY=your_linear_api_key_here
   

4. Build the project:

   npm run build

Usage

Command-line (stdio)

To run the server with stdio transport (for use with CLI tools that support MCP):

npm start

Or:

node dist/index.js stdio

HTTP Server (for remote connections)

To run the server as an HTTP service with Server-Sent Events (SSE):

node dist/index.js http

This will start an HTTP server on port 3000 (configurable via PORT environment variable).

Development Mode

To run in development mode with automatic reloading:

npm run dev

Claude Desktop Integration

To use this server with Claude Desktop:

1. Build the project:

   npm run build

2. In Claude Desktop, go to Settings → Advanced → MCP Configuration.

3. Add the following configuration (adjust paths to match your installation):

   {
     "mcpServers": {
       "linear": {
         "command": "node",
         "args": [
           "/path/to/linear-mcp/dist/index.js"
         ],
         "env": {
           "LINEAR_API_KEY": "your_linear_api_key_here"
         }
       }
     }
   }

4. Save the configuration and restart Claude Desktop.

Alternatively, you can copy the provided claude-desktop-config.json file and modify the paths to match your installation.
