\n\n---\n\n## Tools\n\nNine tools organized around three workflows — author disambiguation, researcher profiling, and cross-server identifier chaining:\n\n| Tool | Description |\n|:-----|:------------|\n| `orcid_search_researchers` | Search the ORCID registry using structured field params (name, affiliation, keyword, ROR ID, DOI, PMID). All params are ANDed into a Solr query against the expanded-search endpoint, returning ORCID iDs with inline name and institution data. |\n| `orcid_get_profile` | Fetch a researcher's public profile: name, biography, keywords, researcher URLs, and external identifiers (Scopus Author ID, ResearcherID, Loop, etc.). |\n| `orcid_get_works` | Retrieve works (publications, datasets, software, preprints) for a researcher. Returns summaries with put-codes, titles, types, dates, journal names, and external identifiers. Returns the first 50 by default with `workCount` and paging via `offset`/`nextOffset` (or `limit`); set `include_external_ids` false for a lighter payload. Pass put-codes to `orcid_get_work_detail` for abstracts and full contributor lists. |\n| `orcid_get_work_detail` | Fetch full detail records for 1–100 works by their put-codes in a single bulk request (from `orcid_get_works`). Returns abstracts, all contributors with CRediT roles, complete external IDs, citation metadata, journal title, and URL. Per-record errors are surfaced without failing the whole call. |\n| `orcid_get_affiliations` | Fetch affiliation records for a researcher. Accepts a `types` list to filter which sections to return: `employment`, `education`, `invited-positions`, `distinctions`, `memberships`, `qualifications`, `services`, or `all`. |\n| `orcid_get_funding` | Fetch funding records: grants, contracts, awards, and salary awards, with funder names, grant numbers, and funding periods. |\n| `orcid_get_peer_reviews` | Fetch peer review activity: convening organizations, reviewer role, review type, completion dates, and ISSN-keyed group identifiers. |\n| `orcid_get_research_resources` | List research resources associated with a researcher — compute allocations, equipment access, lab facilities, and data resources. Sparsely populated; most researchers have no entries. |\n| `orcid_resolve_researcher` | Disambiguate an ambiguous author name to a verified ORCID iD. Returns a ranked list of candidates (5 by default, up to 20 via `rows`) with transparent signals: name match type, institution overlap, and whether a DOI or PMID anchor was used. |\n\n### `orcid_search_researchers`\n\nSearch the ORCID registry with structured field parameters mapped to Solr field queries.\n\n- Structured params — `given_name`, `family_name`, `affiliation`, `keyword`, `ror_id`, `doi`, `pmid` — are ANDed into a Solr query automatically\n- `doi` and `pmid` translate to `doi-self` and `pmid-self` field queries: \"who has linked this work to their ORCID record?\"\n- `query` appends raw Solr to the generated clause for advanced use\n- `ror_id` values (full URLs like `https://ror.org/00f54p054`) are quoted internally to handle Solr's colon parsing\n- Returns expanded-search results with inline name and institution data — no follow-up profile fetch needed for basic discovery\n- Use this for precise field-anchored lookups; use `orcid_resolve_researcher` for ambiguous names needing ranked disambiguation\n\n---\n\n### `orcid_get_profile`\n\nFetch a researcher's public person section by ORCID iD.\n\n- Accepts bare ORCID iD (`0000-0001-2345-6789`) or full URI form\n- Returns name, biography, keywords, researcher URLs, addresses, and external identifiers (Scopus Author ID, ResearcherID, Loop, etc.)\n- External identifiers are embedded in the person response — no separate round-trip\n- Entry point for building a researcher dossier before fetching works or affiliations\n\n---\n\n### `orcid_get_works`\n\nRetrieve the works list for a researcher.\n\n- Returns work summaries: title, type, publication date, journal name, and all external identifiers (DOI, PMID, arXiv ID, ISBN, etc.)\n- Returns the first 50 works by default; `workCount` reports the total available, and prolific records are paged with `offset` plus the returned `nextOffset` (or raise `limit`, max 1000). `truncated` flags when more works remain\n- Set `include_external_ids` to `false` to drop identifier lists when only titles, types, and dates are needed\n- External IDs are returned in formats consumable by downstream servers (Crossref, PubMed, arXiv)\n- Works list is summaries only — chain to the relevant server for full metadata or abstracts\n\n---\n\n### `orcid_get_work_detail`\n\nFetch full detail records for 1–100 works in a single bulk request using the ORCID bulk works endpoint.\n\n- `put_codes` is an array of 1–100 put-codes from `orcid_get_works`\n- Single round-trip regardless of how many put-codes are requested\n- Returns abstracts, all contributors with CRediT roles, the complete external ID list, citation metadata (BibTeX or other formats when deposited), journal title, and URL for each work\n- Per-record errors (not-found or inaccessible put-codes) arrive as `errors` entries — the remaining works still resolve\n\n---\n\n### `orcid_get_affiliations`\n\nFetch affiliation records by type, using a single `/activities` call filtered client-side.\n\n- `types` controls which sections to include: `employment`, `education`, `invited-positions`, `distinctions`, `memberships`, `qualifications`, `services`, or `all`\n- Default is `['employment', 'education']` (the 90% case)\n- Returns organization names, disambiguated org IDs (ROR/GRID/Ringgold), departments, roles, and date ranges\n- One upstream call regardless of how many types are requested — the `/activities` endpoint returns all sections at once\n\n---\n\n### `orcid_get_funding`\n\nFetch funding records for a researcher.\n\n- Returns grants, contracts, awards, and salary awards with funder names, grant numbers, and funding periods\n- Funding data is self-reported and often sparse — absence does not mean no funding\n- Useful when it exists; high-value (grant numbers, funder IDs) but a thin single-endpoint wrapper\n\n---\n\n### `orcid_get_peer_reviews`\n\nFetch peer review activity for a researcher.\n\n- Returns convening organizations (journals/publishers), reviewer role (`reviewer`, `editor`, `chair`, etc.), review type, completion dates, and ISSN-keyed group identifiers\n- Useful for assessing editorial activity and journal affiliations\n\n---\n\n### `orcid_get_research_resources`\n\nList research resources associated with a researcher.\n\n- Covers compute allocations, equipment access, lab facilities, data resources, and clinical study registrations\n- A newer ORCID section that is sparsely populated — most researchers have no entries, and absence does not imply none exist\n- Entries are typically deposited by resource-allocation systems (e.g. ACCESS, XSEDE) rather than self-reported\n- Returns resource title, hosting organization (with disambiguated org ID), external identifiers (often a portal URI), and access period\n\n---\n\n### `orcid_resolve_researcher`\n\nDisambiguate an author name to a verified ORCID iD.\n\n- Returns ranked candidates (5 by default, up to 20 via `rows`) with transparent disambiguation signals: name match type (`exact`/`partial`/`other-name`), institution overlap flag, and anchor type (`doi`/`pmid`/`none`)\n- When `doi` or `pmid` is provided, uses `doi-self` or `pmid-self` as an anchor — researchers who have linked that work to their ORCID record are near-deterministic matches\n- Falls back to a relaxed query (dropping affiliation) if the initial candidate set is empty\n- No synthetic scores — raw signal fields only, so callers can apply their own ranking logic\n\n## Resources\n\n| Type | Name | Description |\n|:-----|:-----|:------------|\n| Resource | `orcid://researcher/{orcid_id}/profile` | Researcher profile (person section: name, bio, keywords, external IDs). Prefer the tool when the response needs to flow into conditional logic. |\n| Resource | `orcid://researcher/{orcid_id}/works` | Works list for a researcher — the first 25 works plus `workCount` (the total available). Use the `orcid_get_works` tool to page the full list. DOIs and PMIDs in the response are ready for Crossref/PubMed chaining. |\n\nAll resource data is also reachable via tools. Use resources when injecting stable researcher context into a prompt; use tools when filtering or processing results is needed.\n\n## Features\n\nBuilt on [`@cyanheads/mcp-ts-core`](https://www.npmjs.com/package/@cyanheads/mcp-ts-core):\n\n- Declarative tool and resource definitions — single file per primitive, framework handles registration and validation\n- Unified error handling — handlers throw, framework catches, classifies, and formats\n- Pluggable auth: `none`, `jwt`, `oauth`\n- Swappable storage backends: `in-memory`, `filesystem`, `Supabase`, `Cloudflare KV/R2/D1`\n- Structured logging with optional OpenTelemetry tracing\n- STDIO and Streamable HTTP transports — HTTP serves MCP protocol revision `2026-07-28` alongside the `initialize`-negotiated 2025 revisions\n\nORCID-specific:\n\n- ORCID Public API v3.0 (`https://pub.orcid.org/v3.0/`) — no API key required for public read endpoints\n- `expanded-search` as the primary search backend — returns ORCID iD, name, and institution data inline, eliminating N+1 profile fetches\n- Single `/activities` call for affiliation queries, filtered client-side — eliminates up to 7 parallel upstream calls vs. per-section fetching\n- External identifiers (DOIs, PMIDs, arXiv IDs) surfaced in works responses in formats ready for cross-server chaining\n\nAgent-friendly output:\n\n- Transparent disambiguation signals in `orcid_resolve_researcher` — name match type, institution overlap, and anchor type are returned as raw fields, not a synthetic score, so agents can reason about match confidence\n- Known-limitation annotations — works list surfaces `num_found` so agents know when the 10,000-result public API cap was hit; funding and profile tools note when sections are empty due to researcher-controlled visibility\n- External identifier pass-through — DOIs, PMIDs, arXiv IDs, Scopus Author IDs are normalized to formats consumable by downstream servers without parsing\n\n## Getting started\n\n### Public Hosted Instance\n\nA public instance is available at `https://orcid.caseyjhand.com/mcp` — no installation required. Point any MCP client at it via Streamable HTTP:\n\n```json\n{\n \"mcpServers\": {\n \"orcid-mcp-server\": {\n \"type\": \"streamable-http\",\n \"url\": \"https://orcid.caseyjhand.com/mcp\"\n }\n }\n}\n```\n\n### Self-Hosted / Local\n\nAdd the following to your MCP client configuration file.

The ORCID Public API is open for public read access. Non-commercial use only under [ORCID Public API ToS §2](https://info.orcid.org/public-client-terms-of-service/).\n\n### Installation\n\n1. **Clone the repository:**\n\n```sh\ngit clone https://github.com/cyanheads/orcid-mcp-server.git\n```\n\n2. **Navigate into the directory:**\n\n```sh\ncd orcid-mcp-server\n```\n\n3. **Install dependencies:**\n\n```sh\nbun install\n```\n\n4. **Configure environment:**\n\n```sh\ncp .env.example .env\n# edit .env if needed — no required vars\n```\n\n## Configuration\n\nAll configuration is validated at startup via Zod schemas in `src/config/server-config.ts`. Key environment variables:\n\n| Variable | Description | Default |\n|:---------|:------------|:--------|\n| `ORCID_API_BASE_URL` | Override the ORCID API base URL. Useful for pointing at the sandbox (`https://pub.sandbox.orcid.org/v3.0/`). | `https://pub.orcid.org/v3.0/` |\n| `MCP_TRANSPORT_TYPE` | Transport: `stdio` or `http` | `stdio` |\n| `MCP_HTTP_PORT` | HTTP server port | `3010` |\n| `MCP_HTTP_ENDPOINT_PATH` | HTTP endpoint path | `/mcp` |\n| `MCP_SESSION_MODE` | HTTP session mode: `auto`, `stateful`, or `stateless`. This server holds no per-session state and ships `stateless`. | `auto` (resolves to `stateful`) |\n| `MCP_PUBLIC_URL` | Public origin for TLS-terminating reverse-proxy deployments | none |\n| `MCP_AUTH_MODE` | Authentication: `none`, `jwt`, or `oauth` | `none` |\n| `MCP_LOG_LEVEL` | Log level (`debug`, `info`, `warning`, `error`, etc.) | `info` |\n| `MCP_GC_PRESSURE_INTERVAL_MS` | Opt-in Bun-only forced-GC pressure loop (ms). Try `60000` if heap growth is observed under sustained HTTP load. | `0` (disabled) |\n| `LOGS_DIR` | Directory for log files (Node.js only) | `/logs` |\n| `STORAGE_PROVIDER_TYPE` | Storage backend: `in-memory`, `filesystem`, `supabase`, `cloudflare-kv/r2/d1` | `in-memory` |\n| `OTEL_ENABLED` | Enable OpenTelemetry | `false` |\n\nSee [`.env.example`](./.env.example) for the full list of optional overrides.\n\n## Running the server\n\n### Local development\n\n- **Build and run:**\n\n ```sh\n # One-time build\n bun run rebuild\n\n # Run the built server\n bun run start:stdio\n # or\n bun run start:http\n ```\n\n- **Run checks and tests:**\n\n ```sh\n bun run devcheck # Lint, format, typecheck, security\n bun run test # Vitest test suite\n bun run lint:mcp # Validate MCP definitions against spec\n ```\n\n### Docker\n\n```sh\ndocker build -t orcid-mcp-server .\ndocker run --rm -p 3010:3010 orcid-mcp-server\n```\n\nThe Dockerfile defaults to HTTP transport, stateless session mode, and logs to `/var/log/orcid-mcp-server`. OpenTelemetry peer dependencies are installed by default — build with `--build-arg OTEL_ENABLED=false` to omit them.\n\n## Project structure\n\n| Directory | Purpose |\n|:----------|:--------|\n| `src/index.ts` | `createApp()` entry point — registers tools and resources, inits services. |\n| `src/config` | Server-specific environment variable parsing and validation with Zod. |\n| `src/mcp-server/tools` | Tool definitions (`*.tool.ts`). Nine tools across search, disambiguation, profile, works, work detail, affiliations, funding, peer reviews, and research resources. |\n| `src/mcp-server/resources` | Resource definitions (`*.resource.ts`). Profile and works resources. |\n| `src/services/orcid` | ORCID Public API v3.0 service layer — search, record section fetchers, retry/backoff. |\n| `tests/` | Unit and integration tests mirroring `src/`. |\n\n## Development guide\n\nSee [`CLAUDE.md`](./CLAUDE.md) for development guidelines and architectural rules. The short version:\n\n- Handlers throw, framework catches — no `try/catch` in tool logic\n- Use `ctx.log` for request-scoped logging, `ctx.state` for tenant-scoped storage\n- Register new tools and resources in the `createApp()` arrays\n- Wrap ORCID API calls: validate raw response → normalize to domain type → return output schema; never fabricate missing fields\n\n## Contributing\n\nIssues and pull requests are welcome.
