Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 944 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name zenodo-mcp-server.

  • Pass
    Lists tools

    tools/list returned 6 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 944 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 944 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    36 of 36 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Pass
    Repo owner matches

    The GitHub repository owner matches the namespace login.

  • Pass

Capabilities

Tools 6

zenodo_get_record

Resolve one Zenodo deposit from a record id, a Zenodo DOI (10.5281/zenodo.N), a concept DOI or concept record id (resolves to the latest version), another DOI deposited on Zenodo, or a zenodo.org or doi.org URL, and return its full metadata: description, creators with ORCIDs and ROR affiliations, license, access and embargo, funding and grants, related identifiers, communities, version position, usage counts, and the first 25 files. Optionally includes a formatted citation. Long text and lists are cut at display caps with their totals reported; every cut except the file list (paged with zenodo_list_files) is listed in continuations with a cursor and the record id it is bound to, and passing both back returns the next window of that field (8,000 characters of text, or the next page of entries) in place of the record. A miss (an unknown id, a deleted record with its removal tombstone, restricted metadata, or a DOI not registered on Zenodo) returns found: false with guidance instead of an error.

Discovered
zenodo_list_files

Page through a Zenodo deposit's file manifest (key, size, MIME type, MD5, download URL, previewability), optionally filtered by a substring of the file key, or list the members inside one of its .zip files by setting archive_key. Restricted and embargoed files return the access status and embargo date with no entries. Read a small text file or ZIP member with zenodo_read_file.

Discovered
zenodo_list_versions

List every version of a Zenodo deposit's version series, newest first, with each version's record id, DOI, version label, publication date, file totals, and usage counts. Accepts any identifier zenodo_get_record accepts; a concept DOI and any single version's DOI list the same series. Use it to find the version a paper cited or the current release. A miss (an unknown id, a deleted record with its removal tombstone, restricted metadata, or a DOI not registered on Zenodo) returns found: false with guidance instead of an error.

Discovered
zenodo_lookup_vocabulary

Resolve names to the ids zenodo_search_records filters on, and browse Zenodo's reference vocabularies: communities (slug), funders (ROR id), awards and grants (award id), licenses (license id), and resource types (type id). Search by name, acronym, or keyword; awards can be scoped to one funder. Each entry names the zenodo_search_records parameter its id feeds.

Discovered
zenodo_read_file

Read a bounded UTF-8 excerpt (up to 64 KiB per call) of one text file in a Zenodo deposit — a README, CITATION.cff, CSV head, notebook, or script — or of one member inside a .zip file, without downloading the archive. Continue a top-level file from next_offset. A file with a text MIME type or extension is read directly; an extensionless file Zenodo types application/octet-stream (LICENSE, COPYING, Makefile) is read and returned only when its content is UTF-8 text. Binary files, restricted files, and other types return metadata and the download URL without content. File content is depositor-supplied and carries the deposit’s license.

Discovered
zenodo_search_records

Search Zenodo's open research repository — datasets, software releases, publications, and other deposits — by keyword query plus filters for resource type, community, funder, grant, creator ORCID, file type, license, access status, and publication date. Returns one summary per deposit (ids, DOIs, title, type, version, creators, license, access, file totals, usage counts) plus facet counts over the full match set, every filter applied. Query terms are OR-ed unless joined with AND, quoted phrases match exactly, and field syntax works on record fields (metadata.title:"…", metadata.subjects.subject:"…"). Only the latest version of each deposit is searched unless all_versions is true, and only the first 10,000 matches are reachable by paging. Resolve community, funder, and grant names to ids with zenodo_lookup_vocabulary first; open one deposit in full with zenodo_get_record.
