CallerKit

Caller ID and phone lookup: names, spam reports, fraud risk score, name/email search.

What it does

CallerKit is a local MCP server that gives an assistant caller ID and phone lookup capabilities. According to its registry description, it can return names associated with a phone number, spam reports, a fraud risk score, and it supports searching by name or email. The manifest does not list individual tools, so the exact tool names and parameters are not documented here.

When to use it

Worth adding when an assistant needs to identify unknown callers, check whether a number has spam reports, or look up a phone number from a name or email. It is a desktop-only local process, so it suits individual workstations rather than shared or web-hosted environments.

Requirements

Runs as a local stdio process, installed from the npm package callerkit-mcp, so Node.js and npm are needed. A CallerKit API key is required and supplied through the environment variable CALLERKIT_API_KEY, obtained from the CallerKit dashboard. An optional CALLERKIT_BASE_URL variable can override the API base URL. Network access to the CallerKit API is required.
