Rings is a relationship intelligence platform for businesses that win on their networks — investment firms, banks, recruiters, and BD and partnerships teams anywhere relationships drive revenue. It unifies people, companies, communications, and deal activity into a live relationship graph. This documentation covers two ways to build on Rings:
  • REST API — programmatic read and write access to contacts, companies, opportunities, notes, and relationship data, scoped by your workspace permissions.
  • MCP server — connect Claude, ChatGPT, and other AI agents directly to Rings so they can search your network, prep meetings, and update records on your behalf.
