Linear

The system for product development, built for planning and building with AI agents.

Updated Sep 27, 2026

Overview

Linear is where product teams and AI agents plan and build: issues, projects, cycles, initiatives and documents, plus Customer Requests that tie feedback from customers to the work it asks for. Its hosted MCP server finds, creates and updates issues, projects, comments and documents. It signs in with OAuth, and also accepts a Linear API key as a bearer token; connect to https://mcp.linear.app/mcp/readonly for read tools only.

The API is GraphQL only: every call is a POST to https://api.linear.app/graphql with a query or mutation in the body. A personal API key goes in the Authorization header as is, without Bearer; an OAuth access token is sent as Bearer <token>.
