Linear Connector

Executable Linear connector for issue search, teams, projects, and approved issue creation.

Credential setup

bearer

Attach a Linear OAuth access token (Bearer). Personal API keys use a different Authorization format and are intentionally not accepted by this preset.

Setup docs: https://linear.app/settings/api

After adding this connector, attach the credential on the server page, then run astrail tools list.

Hosted MCP endpoint

/api/mcp/preset-linear

Private servers require an Astrail API key in the Authorization header.
