What is borme-registry-es?

A lookup skill for Spanish companies using the BORME, Spain's official commercial registry gazette. It uses an MCP server to find company notices, history, appointments, departures, tax IDs, and trademarks.

Use it to investigate a Spanish company's incorporation, history, management changes, registry events, or trademark and tax-ID records.

It avoids manually searching and interpreting scattered registry notices when checking a Spanish company. The skill says not to answer if its BORME server is unavailable.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00182	$0.02588
Opus 5.5	$0.00073	$0.01035
Sonnet 5.5	$0.00036	$0.00518
Haiku 4.5	$0.00018	$0.00259

Security

Grade A, and why

borme-registry-es scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 20d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.

BORME — el Boletín Oficial del Registro Mercantil

El servidor MCP borme contiene los anuncios de sociedades de la sección A del BORME desde 2009, convertidos en eventos tipados, y ofrece además consultas por NIF y por marca. Esta skill indica qué herramienta llamar, cómo encadenarlas y cómo presentar lo que devuelven. La descripción y el esquema de parámetros de cada herramienta explican sus parámetros; léalos también.

Conexión

El endpoint alojado es https://mcp.bormeapi.com/mcp (transporte Streamable HTTP). Funciona sin clave con el plan gratuito. Con clave, envíela en la cabecera X-API-Key:

Claude Code: claude mcp add --transport http borme https://mcp.bormeapi.com/mcp --header "X-API-Key: SU_CLAVE"
Clientes que se configuran con JSON (el mcp.json de Cursor y similares): {"mcpServers": {"borme": {"url": "https://mcp.bormeapi.com/mcp", "headers": {"X-API-Key": "SU_CLAVE"}}}}

Claves: https://bormeapi.com/es/account. Planes y precios: https://bormeapi.com/es/precios.

Si las herramientas de borme no están disponibles en esta sesión, diga que el servidor MCP de BORME no está conectado, facilite al usuario las líneas anteriores y no responda de memoria.

Qué incluye cada plan

Sin clave (free): search_events, company_history y daily_digest sobre los últimos 7 días; list_act_types y registry_stats. 50 llamadas al día por dirección IP.
basic: los últimos 365 días, más company_by_nif, brand_owner y company_brands.
pro: todo lo de basic, con todo el histórico desde 2009.
risk: todo lo de pro, más recent_signals.

Si la respuesta trae plan_window, se aplicó la ventana del plan (company_history lo incluye en todas las respuestas de los planes free y basic). Dígaselo al usuario una vez, en una frase, e indíquele qué cubre el resto: una clave para los últimos 365 días (basic) y pro para todo el histórico. No repita la llamada con fechas anteriores —el servidor las recorta igual— ni tome un resultado vacío como prueba de que antes no pasó nada.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
