Model Context Protocol (MCP) Client for Apify's Actors
Connects to MCP servers via HTTP streamable transport and orchestrates tool calls from LLM responses through a chat UI, supporting dynamic tool selection from remote servers. Bridges browser clients using Server-Sent Events (SSE) to MCP servers, with integrated Claude LLM inference and pay-per-event pricing on Apify's platform. Enables interactive testing of any MCP server or connects to Apify's MCP Server to dynamically access thousands of Actor tools for agent workflows.
About hoot
Portkey-AI/hoot
MCP Testing Tool — Like Postman, but for the Model Context Protocol.
Provides HTTP and SSE transport auto-detection for seamless server connection, plus OAuth 2.1 compliance testing with automatic token management and secure SQLite persistence. The architecture uses a Node.js/Express backend as an MCP client proxy, eliminating browser CORS constraints while enabling conversational tool testing through an AI-powered interface. Deployable locally via npm or to Cloudflare Workers, with shareable "Try in Hoot" links for collaboration.
