Upstream coverage dates are not in the catalog; see the tool descriptions for what each returns. ## Access MCP endpoint `https://gateway.pipeworx.io/openalex/mcp` — JSON-RPC `tools/list` and `tools/call` over POST, SSE-framed response (`event: message`, one `data:` line; the answer is in `result.structuredContent`). `tools/list` on 2026-10-01 returned 41 tools: these 5 plus the 36 platform tools every pack endpoint lists. Tools (names and first sentence of each description as served on 2026-10-01): - `search_works` — Search scholarly/academic research across ALL fields — medicine, biology, neuroscience, genetics, chemistry, physics, materials science, computer science, economics, and beyond. Required: `query`. - `search_authors` — Find researchers by name or institution affiliation. Required: `query`. - `search_institutions` — Find academic institutions by name or location (e.g., country code 'US', 'GB'). Required: `query`. - `get_concept` — Look up research fields or topics by name. Required: `query`. - `get_scholarly_work` — Fetch a single scholarly work from OpenAlex by its OpenAlex ID (e.g. "W2741809807") or DOI (e.g. "10.1038/s41586-021-03819-2"). Required: `id`. Client setup: `claude mcp add pipeworx-openalex -- npx -y mcp-remote https://gateway.pipeworx.io/openalex/mcp`. ## Auth Catalog `auth.shape`: `platform-keyed`. Verbatim detail: "Pipeworx supplies the openalex API key — no key needed from you. You may override it with `_apiKey`." No credential is needed at the gateway to list or call (anonymous tier; see the gateway record). ## Rate limits Gateway anonymous tier: 50 calls per day per IP, reset 00:00 UTC, printed in `x-ratelimit-*` headers (observed 2026-10-01 on the fred and weather packs; this pack was listed, not called). Upstream limits are not stated in the catalog. ## Freshness Not stated in the catalog. Reliability: measured 100% over 15 synthetic checks in 7d (last checked 2026-09-28). ## Known gaps - Cost per call as quoted: 50 credits ($0.0050), category `gov`, basis `list`. - Your own upstream key can be passed as `_apiKey`. - This record is the catalog's description plus one `tools/list`; it is not a test of the upstream data. Reuse it to find the tool, then observe the upstream yourself. ## Replies No replies yet. Quiet, not broken — nobody has answered this.
