Search ORCID researcher profiles, works, affiliations, funding, peer reviews, and disambiguate authors via @cyanheads/orcid-mcp-server

@cyanheads/orcid-mcp-server v0.2.6 — ORCID researcher registry: profiles, works, disambiguation

Install: npm install @cyanheads/orcid-mcp-server Entry: node dist/index.js (stdio transport, ESM) Engine warning: requires Node ≥24 per package.json, but works fine on Node 22. Auth: None required — uses public ORCID API (no client_id/secret needed for public profile data).

Key Gotchas

1. ⚠️ Affiliation org names may show as "Unknown organization" — ORCID public API returns org data only if the researcher made it public AND the org is linked. LeCun's profile shows 3 affiliations but all say "Unknown organization" (his org names are in the search index but not in the public activity endpoint). This is an ORCID data permission issue, not a server bug.
2. ⚠️ `types` param for `get_affiliations` uses hyphenated plurals — valid values: employment, education, invited-positions, distinctions, memberships, qualifications, services, all. Using singular form (e.g. distinction) is rejected.
3. ⚠️ Search by DOI uses `doi-self` Solr field — finds researchers who claimed the DOI on their ORCID profile. Not all authors of a paper will appear (only those who added it to ORCID).
4. `resolve_researcher` returns disambiguation signals — each candidate includes nameMatch (exact/fuzzy), institutionOverlap (yes/no), anchorType (doi/pmid/none). Excellent for author disambiguation in citation matching.
5. `get_works` returns ALL works — Doudna has 523 works. Response can be very large (168KB+). Use get_work_detail with specific put-codes for targeted retrieval.
6. `search_researchers` raw Solr query — pass arbitrary Solr syntax via the query param (e.g. ringgold-org-id:1363). All structured params are ignored when query is provided.
7. Nonexistent ORCID iD → graceful MCP error -32001 with profile_not_found reason.
8. `get_funding` returns structured grant data — includes funder name, funder city/country, grant numbers, and date range (start–end).
9. `get_peer_reviews` returns review activity — organized by convening organization (journal/publisher), with role, type, and completion date.
10. Empty data fields return 0 counts — affiliations, funding, research_resources all return Total: 0 when the researcher hasn't made that data public. No error, just empty result.
