Linear MCP Server: Connecting AI Applications to Linear Data

Overview: What is Linear MCP Server?

The Linear MCP Server is an essential component in establishing a seamless bridge between AI applications and the powerful data management system offered by Linear. Built specifically for integrating with Linear's API, it enables AI desktop clients like Claude Desktop, Continue, and Cursor to interact with teams, issues, projects, and cycles within Linear's ecosystem.

🔧 Core Features & MCP Capabilities

The Linear MCP Server is designed with a suite of core functionalities that significantly enhance the interaction between AI applications and Linear. Key features include:

• Team Management: Retrieve comprehensive information about all teams in your Linear account.
• Issue Search and Filtering: Conduct precise searches for issues, managing pagination and filtering to fetch relevant data.
• Cycle and Project Access: Identify and retrieve detailed cycle data for specific teams, as well as list projects within a team or across the entire organization.
• Issue Creation and Update: Support both creating new issues with customizable details such as title, description, state, and more; and updating existing issues to reflect ongoing changes.

These features are achieved through robust implementation of MCP (Model Context Protocol), ensuring that any MCP-compliant client application can leverage these functionalities seamlessly. By adhering to a standardized protocol, the server facilitates smooth data exchange and interaction between diverse AI desktop platforms and the Linear API.

⚙️ MCP Architecture & Protocol Implementation

The architecture of the Linear MCP Server is intricately designed around the principles of Model Context Protocol (MCP). Each function is built as an MCP client tool that adheres to strict specifications, ensuring compatibility across various AI application environments. The server utilizes TypeScript and the official Linear SDK for implementation, providing a secure and efficient means of communication between the AI applications and Linear's API servers.

🚀 Getting Started with Installation

Step 1: Install the Server

For users leveraging Cline MCP Marketplace, follow these steps to install the MCP server:

• Clone the repository:

  git clone https://github.com/cpropster/linear-mcp-server.git
  

• Navigate to the project directory:

  cd linear-mcp-server
  

• Install necessary dependencies:

  npm install
  

• Build the server execution package:

  npm run build
  

Step 2: Configuration

The MCP server requires setting up your Linear OAuth token, which is crucial for authentication. Follow these steps to obtain and integrate:

1. Create a Linear OAuth Application: Go to the Linear settings page.
2. Set Up OAuth Application Details:
   • Name the Application "Cline MCP".
   • Set the redirect URI to http://localhost:3000/callback.
   • Remember your client ID and secret.
3. Generate a User-Based Developer Token: Use it as part of your configuration.

Step 3: Verify Installation

Ensure that the server is properly configured and operational by testing its connection:

• Reload the MCP configuration:
• Test using the linear_search_issues tool:

  use_mcp_tool(
    server_name="github.com/cpropster/linear-mcp-server",
    tool_name="linear_search_issues",
    arguments={
      "query": "Optional search query",
      "teamIds": ["Optional team IDs"],
      "first": 10 // Number of issues to return (default: 50)
    }
  )
  

Upon a successful connection, you should receive a list of issues from your Linear account. Errors indicate configuration or credential issues that need addressing.

💡 Key Use Cases in AI Workflows

Real-World Scenario 1: Issue Management for Development Teams

AI-driven development teams can leverage the Linear MCP Server to streamline issue management within their projects. By integrating with tools like Claude Desktop, teams can easily track and manage bugs, feature requests, and tasks directly from AI-driven interfaces.

For example, when a developer identifies a bug, they use the linear_create_issue tool to log it into Linear through Claude Desktop. This integration ensures that all developers have access to real-time updates on issue status, assignments, and resolutions.

Real-World Scenario 2: Project Progress Monitoring

Artificial intelligence can also significantly enhance project management processes by providing visibility into ongoing projects via the Linear MCP Server. For instance, an AI application could utilize linear_get_projects to fetch a summary of all active projects in real-time. This capability enables informed decision-making and task prioritization.
