Linear MCP Server: Connecting AI Applications to Linear's API Ecosystem

Overview: What is Linear MCP Server?

The Linear MCP Server is an infrastructure designed to facilitate seamless integration between popular AI applications and the Linear project management tool via Model Context Protocol (MCP). By leveraging MCP, this server ensures that AI applications like Claude Desktop, Continue, Cursor, and others can access and manipulate data from Linear with ease. The server supports a wide range of operations, making it ideal for developers working on sophisticated AI workflows and integrations.

🔧 Core Features & MCP Capabilities

The Linear MCP Server offers several essential features and corresponding MCP capabilities that enable robust integration:

1. Issue Management: Create, update, delete, search, and associate issues with projects.
2. Project Management: Manage project creation, get project information, and associate issues with the appropriate project.
3. Team Management: Access detailed team information, states, labels, and other relevant metadata.
4. Authentication: Support for personal access tokens (recommended) and OAuth flow (alternative).
5. Batch Operations: Handle bulk issue creation and deletion efficiently.
6. Bulk Updates: Implement parallel processing for bulk updates (currently in testing).

Detailed Protocol Implementation

The MCP protocol is implemented to ensure seamless communication between the server and various AI applications. Each API call is translated into a standardized MCP request, making it easier for both developers and AI applications to interact with Linear.

⚙️ MCP Architecture & Protocol Implementation

The architecture of the Linear MCP Server is designed to be scalable and robust:

1. Client-Side Communication: Communicates via MCP protocol using a defined set of commands.
2. Server-Side Processing: Manages API requests, ensures security, and implements logic for handling data.
3. Data Flow: Data flows through multiple layers to ensure integrity and security.
