Linear MCP Server

> Note: This is a custom implementation. For the official Cline Linear MCP server, see cline/linear-mcp.

A Model Context Protocol (MCP) server that provides tools for interacting with Linear's API, enabling AI agents to manage issues, projects, and teams programmatically through the Linear platform.

Features

- Issue Management

- Create new issues with customizable properties (title, description, team, assignee, priority, labels)
- List issues with flexible filtering options (team, assignee, status)
- Update existing issues (title, description, status, assignee, priority)

- Team Management

- List all teams in the workspace
- Access team details including ID, name, key, and description

- Project Management
- List all projects with optional team filtering
- View project details including name, description, state, and associated teams

Prerequisites

- Node.js (v16 or higher)
- A Linear account with API access
- Linear API key with appropriate permissions

Quick Start

1. Get your Linear API key from Linear's Developer Settings

2. Run with your API key:

``bash
LINEAR_API_KEY=your-api-key npx @ibraheem4/linear-mcp
`

Or set it in your environment:

`bash
export LINEAR_API_KEY=your-api-key
npx @ibraheem4/linear-mcp
`

Development Setup

1. Clone the repository:

`bash
git clone [repository-url]
cd linear-mcp
`

2. Install dependencies:

`bash
npm install
`

3. Build the project:

`bash
npm run build
`

Running with Inspector

For local development and debugging, you can use the MCP Inspector:

1. Install supergateway:

`bash
npm install -g supergateway
`

2. Use the included run.sh script:

`bash
chmod +x run.sh
LINEAR_API_KEY=your-api-key ./run.sh
`

3. Access the Inspector:
- Open localhost:1337 in your browser
- The Inspector connects via Server-Sent Events (SSE)
- Test and debug tool calls through the Inspector interface

Configuration

Configure the MCP server in your settings file based on your client:

`json
{
"mcpServers": {
"linear-mcp": {
"command": "node",
"args": ["/path/to/linear-mcp/build/index.js"],
"env": {
"LINEAR_API_KEY": "your-api-key-here"
},
"disabled": false,
"alwaysAllow": []
}
}
}
`

$3

Location: ~/Library/Application Support/Code/User/globalStorage/rooveterinaryinc.roo-cline/settings/cline_mcp_settings.json

`json
{
"mcpServers": {
"linear-mcp": {
"command": "node",
"args": ["/path/to/linear-mcp/build/index.js"],
"env": {
