CallerKit MCP

The CallerKit MCP server enables AI assistants to perform global caller ID lookups, assess fraud risk scores for phone numbers, and search for contact information by name or email. It supports bulk lookups and integrates directly with CallerKit's API credentials, offering tools for phone lookup, risk assessment, and contact search.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http callerkit-mcp https://mcp.caller-kit.com/mcp
