## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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)

## MCP tools (3)

### `eps_publication_dates` (~185 tokens)

List EPO European Publication Server publication dates (almost always Thursdays, weekly since 1978) with a real document count per date. Filter by "year" (e.g. "2026") or a "from"/"to" range (YYYYMMDD or YYYY-MM-DD); omit both to get the most recent dates. Use a returned date with eps_list_publications to see what was published that day.

Input parameters:

- `from` (string): Start of a date range, inclusive, YYYYMMDD or YYYY-MM-DD.
- `limit` (number): Max dates to return, newest first (default 20, max 100).
- `to` (string): End of a date range, inclusive, YYYYMMDD or YYYY-MM-DD.
- `year` (string): Four-digit year, e.g. "2026". Filters to publication dates in that year.

### `eps_list_publications` (~271 tokens)

List every EP patent publication issued on one EPO publication date, with publication number, kind code, title and applicant(s). Returns the real total on that date before any filtering. "date" must be a real EPO publication date (get one from eps_publication_dates) — an arbitrary date fails loudly rather than silently returning nothing. "kind" filters to a kind code ("A1" newly-published application, "A2" application without search report, "A3" search report, "B1"/"B2"/"B3" granted-patent stages) or a bare letter ("A" or "B") for either family.

Input parameters:

- `date` (string, required): EPO publication date, YYYYMMDD or YYYY-MM-DD, e.g. "2026-10-14". Must be a real EPO publication date.
- `kind` (string): Kind-code filter: "A1", "A2", "A3", "B1", "B2", "B3", or bare "A" / "B".
- `limit` (number): Max publications to return with title/applicant detail (default 20, max 50). "total_on_date" and "total_matching_filter" always report the real counts regardless of this limit.

### `eps_get_document` (~271 tokens)

Fetch one EP patent publication as published by the EPO — bibliographic data, or the full text of its abstract, claims or description. Give "number" as a full id from eps_list_publications (e.g. "EP4819826NWA1", recommended) or a bare publication number ("EP4819826") plus "kind" ("A1", "B1", ...). Full claims/description text is reliably present for GRANTED (B-kind) patents and directly-filed (non-PCT) applications; a Euro-PCT national-phase entry (the common case) carries only the bibliographic record here because its full text was already published as a WIPO pamphlet — the response says which case it hit rather than returning an empty result.

Input parameters:

- `kind` (string): Kind code, e.g. "A1", "B1". Required if "number" is a bare publication number without one.
- `number` (string, required): Full publication-server id (e.g. "EP4819826NWA1") or bare publication number (e.g. "EP4819826").
- `part` (string): Which part to return: "biblio" (default — title, applicants, dates, classifications), "abstract", "claims", or "description".

## Common questions

### What is the Epo Publication Server MCP server?

Epo Publication Server is an MCP server listed in the public MCP registry as io.github.pipeworx-io/epo-publication-server. EPO European Publication Server (EPS) MCP. This page covers its npm package (@pipeworx/mcp-epo-publication-server).

### Is the Epo Publication Server MCP server safe to use?

Epo Publication Server scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Epo Publication Server MCP server expose?

Epo Publication Server exposes 3 tools: eps_publication_dates, eps_list_publications, eps_get_document. Their descriptions and schemas cost roughly 727 tokens of context every time the server is loaded.

### Is the Epo Publication Server MCP server still maintained?

Epo Publication Server is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Epo Publication Server MCP server under?

Epo Publication Server declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Epo Publication Server MCP server?

VerifyMCP ran 16 checks on Epo Publication Server, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
