Implementation Reference
- src/APIMarketMCPServer.ts:195-322 (handler)This is the execution handler for all MCP tools, including "getWhoisInfo". It finds the tool by name or ID, reconstructs the HTTP method and path from the tool ID, builds the request using axios, handles GET params and POST body, and returns the API response as text content.
