Euipo MCP server

@pipeworx/euipo

EU trademark search, registered Community design search, the harmonised Nice goods-and-services classification, the Locarno product-indications classification, and the applicant/representative register, all from the European Union Intellectual Property Office (EUIPO).

Part of Pipeworx — an MCP gateway connecting AI agents to 1879+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

• euiposearchtrademarks(...) — search EU trademarks (EUTM) by verbal element, applicant, Nice class, or status.
• euipo_trademark(...) — retrieve a single EU trademark by application/registration number.
• euiposearchdesigns(...) — search registered Community designs (RCD) by indication, owner, or Locarno class.
• euiposearchgoods_services(...) — explore/search the harmonised Nice goods-and-services classification (useful for trademark clearance and filing prep).
• euipovalidategoods_services(...) — validate a list of goods-and-services terms against the harmonised database; flags invalid characters, duplicates, forbidden terms.
• euiposearchproduct_indications(...) — search the harmonised Locarno product-indications classification used in design filings.
• euiposearchpersons(...) — search applicants or representatives on record for EUIPO trademark/design procedures. No street/city/postal address for individuals — only country-level location is kept; every row carries a source and a role label.

Auth

BYO only. Register a free application at dev.euipo.europa.eu and pass apiKey = "clientid:client_secret". Subscribe the app to the "Trademark search", "Design Search", "Goods and Services", "Product Indications" and "Persons" API products (one free app covers all five). There is no platform key for this pack by design — Pipeworx does not hold or pay for an EUIPO credential.

Data sources

• EUIPO, EU trademark register (EUTM)
• EUIPO, Registered Community design register (RCD)
• EUIPO, harmonised Nice goods-and-services classification (used for trademark filings)
• EUIPO, harmonised Locarno product-indications classification (used for design filings)
• EUIPO, applicant and representative register

Notes

pack manifest, workspace dependencies, or catalog, so it logged zero external calls regardless of credential state. Wired in as part of fleet #3309 (2026-10-18), which also corrected the OAuth token endpoint (see below) and added the four tools above.

• Built 2026-07-14 and committed dormant — never added to the gateway's

(auth.euipo.europa.eu/oidc/accessToken, a dead host that returns a flat HTTP 502 — never a 401/403, so no credential could ever have worked against it). The corrected endpoint, confirmed against five independent EUIPO developer-portal OpenAPI specs, returns a proper CAS 401 challenge for bad/placeholder credentials.

• The token endpoint was wrong in the original build

(verbalElement=="nike";niceClasses=in=(9,25)); the newer three tools (Goods and Services, Product Indications, Persons) are plain query-param REST with no RSQL.

• The Trademark Search / Design Search tools use RSQL filter expressions

details for natural persons (individual applicants, employee/legal/EUIPO-professional representatives) and keeps only the country. Organisation-type rows (business applicants, legal-association representatives) keep their registered address, since that is public-register entity data rather than a personal address.

• Privacy: euiposearchpersons withholds street/city/postal-code address
