Linear MCP Server

A Model Context Protocol (MCP) server implementation for the Linear GraphQL API that enables AI assistants to interact with Linear project management systems.

Features

• Access to Linear's GraphQL API through MCP tools
• Authentication via Linear API key
• Retrieve and modify data related to users, teams, projects, and issues
• Create, update and comment on issues
• Add and remove labels
• Create projects
• Comprehensive documentation of available tools

Available Tools

See TOOLS.md for a complete list of available tools and planned features.

Overview

Linear-MCP-Server bridges the gap between Claude (AI assistant) and Linear (project management tool) by implementing the MCP protocol. This allows Claude to:

• Retrieve issues, projects, teams, and other data from Linear
• Create and update issues
• Change issue status
• Assign issues to team members
• Add comments
• Create projects and teams

The server uses Linear's GraphQL API and authenticates via user tokens (not OAuth) for simplicity.

Using with Claude Desktop

To use this MCP server with Claude Desktop:

1. Enable Developer Mode in Claude Desktop (from the menu bar)
2. Go to Settings > Developer options
3. Click "Add Server"
4. Configure with the following settings:
   • Name: Linear MCP Server
   • Type: Local Process
   • Command: linear-mcp-server
   • Arguments: --token YOUR_LINEAR_API_TOKEN

Alternatively, manually edit the config file:

{
  "mcp": {
    "servers": [
      {
        "name": "Linear MCP Server",
        "transport": {
          "type": "stdio",
          "command": "linear-mcp-server",
          "args": ["--token", "YOUR_LINEAR_API_TOKEN"]
        }
      }
    ]
  }
}

5. Save the config
6. Restart Claude Desktop (quit completely and reopen)
7. You should now see Linear MCP Server available as a tool in Claude
