No request limits are published, API tokens carry their user's full permissions, and 83 security advisories were published in the last twelve months, 13 rated critical.\n\n## Before you call either\n\n### Linear MCP\n\n1. Use `https://mcp.linear.app/mcp/readonly` for triage and reporting, it only exposes read tools\n2. Headless runs take `Authorization: Bearer \u003cAPI key\u003e`, and a key created with Read permission can't write\n3. Treat an HTTP 400 with RATELIMITED as a rate limit and wait for the X-RateLimit-Requests-Reset time\n4. Call `list_teams` first, since team visibility and retired teams come back in its output\n\n### OpenProject\n\n1. Send the API token as `Authorization: Bearer \u003ctoken\u003e`, or as the Basic auth password with the user name `apikey`\n2. Read the resource first and send its current `lockVersion` with every PATCH. A stale value returns 409 `UpdateConflict`\n3. POST to the `/form` endpoint of a work package to learn writable fields and allowed values before creating or updating\n4. URL-encode `filters` as a JSON array, and add `pageSize`, `offset` and `select` to keep work package lists small\n5. Run the agent as a dedicated user with a narrow project role, and treat work package text and comments as untrusted input\n\n## Questions\n\n### Which is better for AI agents, Linear MCP or OpenProject?\n\nOpenProject scores 57.4 (C) on agent readiness against Linear MCP's 53.8 (D), and leads in 4 of 7 scored categories. Linear MCP leads on reliability and security \u0026 auth.\n\n### Do Linear MCP and OpenProject need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Linear MCP and OpenProject without installing anything?\n\nLinear MCP has a hosted endpoint at https://mcp.linear.app/mcp. No hosted endpoint is listed for OpenProject.\n\n### Are Linear MCP and OpenProject open source?\n\nNo open-source release is listed for Linear MCP. OpenProject is open source (GPL-3.0 for the OpenProject source. Enterprise add-ons need a paid token, and OpenProject Enterprise cloud runs under OpenProject's Terms of Service).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/linear-mcp-vs-openproject.json, and with the fewest tokens: https://www.anchorterminal.com/compare/linear-mcp-vs-openproject.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"linear-mcp\", \"b\": \"openproject\"}`.
