An API key from the service settings is required

Give your agents a live line into official law. SourceActs is a hosted MCP server. Connect Claude, Cursor, or ChatGPT to public regulatory sources and monitor updates, query instruments, and pull metadata — without custom scrapers or paid database seats.

How to connect

  5. In a chat, click + → Connectors and switch the new connector on.

Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.
