MCP BORME

A Model Context Protocol (MCP) server for the BORME (Boletín Oficial del Registro Mercantil, Spain's commercial-registry bulletin), built on the public OpenMercantil API. It lets AI assistants like Claude search Spanish companies, read their registry history and officers, browse the daily bulletin, map sectors by CNAE, look at public procurement and consult the mercantile-law norms behind each registry act.

Independent and informational. OpenMercantil is not the BOE, the BORME or the

Registro Mercantil, and its data does not replace official certificates or registry

extracts. BORME material is re-used under Ley 37/2007; the official version is on

boe.es. Tool responses keep the source attribution

(_attributions) and the tool descriptions repeat the documentary, not-legal-advice caveats.

No account needed

The OpenMercantil API is public: this server works out of the box on its anonymous free tier (60 requests/minute and 200 requests/day per IP). An optional API key (OPENMERCANTILAPIKEY, omk_..., from openmercantil.es) selects your account's larger quota:

Plans change — see openmercantil.es and docs/api-notes.md. With 200 requests a day, the server is built to be frugal:

costs a request.

  • Every input is validated locally against the OpenAPI bounds, so a bad call never

big payloads are trimmed with an explicit notice (eventstotal, eventstruncated, total_acts...) so the assistant knows what it did not see and which tool pages the rest. A full company report (~60 KB) arrives as ~6 KB; a full day of the bulletin (~340 KB) as a per-province summary.

  • Result counts default to small numbers (10 results, 10 events, 10 acts per province) and

valid-JSON envelope that says it was cut.

  • Any response above OPENMERCANTILMAXRESPONSE_CHARS (default 60,000) is replaced by a

how to get a larger quota. Short Retry-After values are honoured automatically; long ones (the daily quota) are reported immediately instead of blocking.

  • Responses carry the API's rate-limit state; a 429 reports the plan, when to retry and
