Remote (streamable-http)

https://registrum.co.uk/api/mcp Responded, but not as an MCP endpoint

Claude Code:

claude mcp add --transport http uk-companies-house-mcp https://registrum.co.uk/api/mcp

Or add to your MCP client config:

{
  "mcpServers": {
    "uk-companies-house-mcp": {
      "url": "https://registrum.co.uk/api/mcp"
    }
  }
}

Package (npm 2.0.15)

npx -y @registrum/[email protected]

Or add to your MCP client config:

{
  "mcpServers": {
    "uk-companies-house-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@registrum/[email protected]"
      ],
      "env": {
        "REGISTRUM_API_KEY": "<YOUR_VALUE>"
      }
    }
  }
}

REGISTRUM_API_KEY secret — Optional. Without it the server uses the keyless hosted endpoint https://registrum.co.uk/api/mcp, which has daily caps. A free key gives 60 days of full access (every endpoint, no monthly cap, no card), then stays free for light use. Get a free key at https://registrum.co.uk/?utm_source=mcp&utm_campaign=registry
