UK Companies House + Gemini
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.
Prerequisites
See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:
COMPANIES_HOUSE_API_KEY
Step 1 — Get credentials
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)
Step 2 — Install the adapter
git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d
Step 3 — Add the connector in Gemini
Gemini CLI reads MCP servers from ~/.gemini/settings.json (or %APPDATA%\gemini\settings.json on Windows). Add:
{
"mcpServers": {
"anythingmcp": {
"httpUrl": "https://cloud.anythingmcp.com/mcp",
"headers": { "Authorization": "Bearer YOUR_MCP_API_KEY" }
}
}
}
- Get your MCP API key from AnythingMCP → Profile → MCP API Keys → New Key.
- Save the file and restart
gemini. - Run
/mcpinside the Gemini CLI —UK Companies Houseshould be listed as available. - Vertex AI Studio: pass
https://cloud.anythingmcp.com/mcpto thetoolsarray of your request with the same Bearer header.
