Linear MCP Server

A Model Context Protocol (MCP) server that provides AI assistants (Claude, Cursor, etc.) with a comprehensive interface to the Linear API via GraphQL. Supports both static API keys and OAuth2 authentication.

Overview

linear-mcp allows your AI assistant to directly interact with your Linear workspace. It enables powerful natural language queries like:

• "What are the open issues assigned to me in the 'Backend' team?"
• "Show me the details of issue LIN-1234."
• "List all active projects and their progress."
• "Which teams exist in our workspace?"

Features

• GraphQL API: Leverages Linear's GraphQL API for efficient, precise queries.
• OAuth2 Support: Browser-based OAuth flow with automatic token refresh, powered by @vineethnkrishnan/oauth-core.
• Static Token Support: Use a Linear API key for simple setups.
• Modular Architecture: Built with clean layered design for high maintainability.
• Type-Safe: Fully implemented in TypeScript with Zod schema validation.
• Comprehensive Coverage: Full access to Issues, Projects, and Teams.

Installation

Using npx (Recommended)

No installation required. Run directly:

npx -y @vineethnkrishnan/linear-mcp

Global Install

npm install -g @vineethnkrishnan/linear-mcp
linear-mcp

From Source

git clone https://github.com/vineethkrishnan/mcp-pool.git
cd mcp-pool
npm install
npm run build

Configuration

To use this server with an MCP client like Claude Desktop, add to your MCP client configuration file:

| Platform | Config file path | |----------|-----------------| | macOS | ~/Library/Application Support/Claude/claude_desktop_config.json | | Windows | %APPDATA%\Claude\claude_desktop_config.json | | Linux | ~/.config/Claude/claude_desktop_config.json |

Using a Static API Key

{
  "mcpServers": {
    "linear": {
      "command": "npx",
      "args": ["-y", "@vineethnkrishnan/linear-mcp"],
      "env": {
        "LINEAR_API_KEY": "lin_api_..."
      }
    }
  }
}

Using OAuth2

{
  "mcpServers": {
    "linear": {
      "command": "npx",
      "args": ["-y", "@vineethnkrishnan/linear-mcp"],
      "env": {
        "LINEAR_CLIENT_ID": "abc12345...",
        "LINEAR_CLIENT_SECRET": "lin_oauth_secret_..."
      }
    }
  }
}

Then run the OAuth setup:

linear-mcp auth login

This will:

1. Open a browser window where you'll log in to Linear and authorize the app
2. After you approve, the browser will show a success message
3. Your tokens are saved locally at ~/.mcp-pool/linear/ and refresh automatically

Environment Variables

| Variable | Required | Default | Description | |----------|----------|---------|-------------| | LINEAR_API_KEY | No* | - | Static Linear API key. | | LINEAR_CLIENT_ID | No* | - | OAuth2 client ID. | | LINEAR_CLIENT_SECRET | No* | - | OAuth2 client secret. |

*Either LINEAR_API_KEY or both LINEAR_CLIENT_ID and LINEAR_CLIENT_SECRET must be provided.

Getting Your Credentials

Option A: Personal API Key (Simpler)

1. Go to linear.app/settings/api
2. Under Personal API keys, click Create key
3. Copy the key (starts with lin_api_)

Option B: OAuth App

1. Go to linear.app/settings/api > OAuth applications
2. Click Create application
3. Copy the Client ID and Client secret
