Lobe Chat
LobeChat is a open-source, extensible (Function Calling), high-performance chatbot framework.It supports one-click free deployment of your private ChatGPT/LLM web application.
Project mention: MCP Proxy Pattern: Secure, Retrieval-First Tool Routing for Agents | dev.to | 2025-08-20It’s worth noting that the ecosystem of MCP servers is expanding very rapidly. There are already thousands of MCP servers available, covering everything from Slack bots to web scraping to code execution. Community-driven directories like Pulse MCP, Glama MCP server directory, Smithery, and LobeHub marketplace (see the LobeHub MCP index) list thousands of servers and provide usage stats. Anthropic and others are working on an official MCP registry to standardize how agents discover and install these servers dynamically. In short, the raw material (tools) is out there; the challenge is connecting the right tool at the right time. A middleware like MCPProxy, especially paired with an intelligent registry search, could let agents tap into this vast toolbox on demand without human micromanagement.
