CallerKit MCP

The CallerKit MCP server enables AI assistants like Claude and Cursor to perform global caller ID lookups, assess fraud risk scores, and search for contact information by name or email. It supports both hosted connectors and local execution via npx, integrating directly with the CallerKit REST API using an API key for authentication and credit-based usage.
