Linear MCP Server

Linear's official hosted remote MCP server (mcp.linear.app) for finding, creating, and updating issues, projects, and comments. OAuth 2.1 with dynamic client registration (API key / Bearer token also accepted) over Streamable HTTP. Replaces the community dvcrn/mcp-server-linear listing. Note: scores other than authentication are a provisional assessment from Linear's documentation pending a live tool-level audit.

Authentication & Identity

LOWImplements MCP OAuth spec for per-user authentication

Official first-party remote MCP server at https://mcp.linear.app/mcp implementing OAuth 2.1 with dynamic client registration; a Linear API key or OAuth access token may also be passed via the Authorization header (including a restricted read-only key). Centrally hosted and managed by Linear over Streamable HTTP (SSE deprecated).

Remediation

Document the required OAuth scopes for each tool.

Tool Schema Quality

MEDIUMTool schemas not independently audited

The hosted server has no public source repository, so tool input schemas, required fields, and parameter constraints could not be verified directly. Provisional score pending a live tool-level audit.

Remediation

Run a live audit against the hosted endpoint to enumerate and score tool schemas.

Data Exposure

MEDIUMPagination and field selection not verified

Whether list operations paginate and support field selection could not be verified without a live audit of the hosted tool surface.

Remediation

Audit list operations for pagination and field-selection support.
