Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog) Scored 2026-11-04. - **Endpoint Security**: 83/100 - The endpoint's TLS certificate is valid, in date, and uses a strong key. - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. - HTTPS is enforced; there's no plaintext access path. - The HSTS (Strict-Transport-Security) header is present. - DNSSEC is configured correctly; the domain's records validate against the full chain to the root. - **Transport & Reachability**: 100/100 - Verified streamable-http transport via a live MCP handshake. - **Schema Quality & AI Usability**: 73/100 - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name). - AI-judged instruction clarity (excellent). - Context-footprint check failed: tool/resource definitions use about 3363 tokens (~480/item across 7 items; 6 tools + 1 resources), over budget; trim descriptions and params. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 58/100 - Stability check failed: schema churn in the 25 days we've observed: 0 tool removals, 3 breaking changes, 0 auth/transport breaks, 0 additions. - **Tool Coverage**: 100/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 100% of tool parameters carry a description. - Structured output schemas are declared (100% of tools); any adoption earns full credit. - **Tool Safety**: 100/100 - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured. - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation. - An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it. - **Capabilities**: 100/100 - Implements a current MCP spec version (2026-07-28). ## Install ### How do I install the io.github.cyanheads/datacite-mcp-server server? io.github.cyanheads/datacite-mcp-server is a hosted endpoint at https://datacite.caseyjhand.com/mcp, so there is nothing to install locally.

Long lists are capped with exact list/offset continuation recipes; select a list to retrieve later entries without losing the other metadata. datacite_trace_relations maps a bounded graph (at most 100 nodes and 1,000 edges). A DOI DataCite does not hold returns found: false naming the registration agency that does, or saying the DOI does not exist. Input parameters: - `doi` (string, required): The DOI, e.g. 10.5061/dryad.234: 10., a 4–9 digit registrant, a slash, and a suffix.

Accepts any DOI, including a journal article's DOI, to find the datasets and software it cites and those that cite, supplement, or derive from it. DataCite DOIs are hydrated with title, type, year, repository, and citation count; other identifiers stay leaf nodes. Depth 1 by default, at most 2, with a node cap (default 50, max 100) disclosed when it binds. An absent edge is not evidence that no relationship exists. Input parameters: - `depth` (integer): Hops from the root: 1 (default) or 2. Depth 2 expands at most 10 DataCite neighbours through their own and reverse metadata, and runs only while max_nodes has room after the first hop. - `doi` (string, required): The root DOI — any agency's, e.g. a DataCite dataset 10.5061/dryad.234 or a journal article's DOI. Bare, doi:, or a doi.org URL; case-insensitive. - `event_offset` (integer): Absolute zero-based Event Data position, 0–9,999.

Filled in order: own-metadata targets, records po… - `relation_types` (array): Only these relation types (IsVersionOf, HasPart, IsSupplementTo, IsDerivedFrom, Cites, IsCitedBy, …), any case, read from the traced DOI's side: HasPart keeps the DOI's own HasPart assertions and the… Output parameters: - `cap` (number): The max_nodes applied. - `coverage` (object): What each source contributed and how much of it was read. - `edges` (array): Edges between returned nodes, at most 1,000, the first found; identical edges from several sources are merged. - `edgesFound` (number): Edges between the returned nodes before the 1,000-edge cap; present only when the cap bound. - `error` (object): Present when the call failed. Absent on success. - `nodes` (array): Nodes, root first. - `notice` (string): Coverage caveats: non-DataCite root, no relations found, Event Data unavailable, records pointing at a DOI too large to read 100 of, Event Data objects left out and nodes left unhydrated because Data… - `root` (object): The root DOI. For another agency's DOI, title, type, and year come from DataCite's linking copy when it holds one. - `rootCounts` (object): DataCite's own counts for the root (DataCite roots only), to compare with the edges shown. - `shown` (number): Nodes returned, root included. - `truncated` (boolean): True when max_nodes or the 1,000-edge cap bound. ### `datacite_search_repositories` (~500 tokens) Search DataCite repositories Find DataCite repository accounts by name or description text, field of science, repository type, certification (e.g. CoreTrustSeal), software platform, client type, or parent provider, or look up known repository IDs. Returns each repository's repositoryId — the value datacite_search_works takes in repository_ids — with its providerId, name, type, certificates, software, subjects, homepage, and re3data link. To rank repositories by how many works they hold on a topic, run datacite_search_works with that topic and include_facets: true; its repositories facet lists the top ten with counts. Input parameters: - `certificates` (array): Certificates (any match): CoreTrustSeal, WDS, DSA, DINI, RatSWD, CLARIN, DIN 31644; any case. - `client_type` (string): Account type: repository, periodical, igsnCatalog, or raidRegistry.
