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>`.
