UK Companies House + Claude

Search and inspect the official UK companies register: company profiles, directors and secretaries, filing history. Free public API with a 600 requests / 5 minutes rate limit. The UK equivalent of the German Handelsregister.

Предварительные требования

Полные инструкции по настройке встроены в коннектор (видны в магазине при выборе коннектора). Требуемые переменные окружения:

COMPANIES_HOUSE_API_KEY

Шаг 1 — Получите учётные данные

Getting an API key: register a free account at https://developer.company-information.service.gov.uk → 'Manage applications' → 'Create an application' (pick Live or Test) → 'Create new key' → REST. Copy the generated key into COMPANIES_HOUSE_API_KEY.

Authentication quirk: Companies House uses HTTP Basic Auth where the API key is the username and the password is empty (the canonical curl shape is -u API_KEY:). This adapter mirrors that — leave the password configuration empty.

Company numbers: always 8 characters, zero-padded (e.g. 00006400 not 6400). The search endpoint returns matches with the canonical number you can feed into the other tools.

…(continued in the in-app connector instructions)

Шаг 2 — Установите адаптер

git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d

Шаг 3 — Добавьте коннектор в Claude

Рекомендуемый путь — работает в claude.ai web без редактирования конфигурационных файлов.

  1. Откройте claude.ai/customize/connectors.
  2. Нажмите "Add custom connector".
  3. Заполните:
    • Name: UK Companies House
    • URL: https://cloud.anythingmcp.com/mcp
    • Authentication: Bearer token → вставьте ваш MCP API key (из AnythingMCP → Profile → MCP API Keys → New Key)
  4. Нажмите Connect для авторизации.
