Feature Request: MCP Server for AI Agent Express.js App Introspection

## Feature Request ### Description An MCP server for Express.js applications would let AI agents introspect and interact with Express apps via the Model Context Protocol. ### Use Case AI coding assistants working with Express apps could: - List registered routes and middleware - Test endpoints with structured tool calls - Query app configuration - Monitor request/response patterns ### Context The MCP ecosystem (8M+ downloads) enables AI agent tool discovery. Tools like [ToolPipe MCP Server](https://github.com/COSAI-Labs/toolpipe-mcp-server) demonstrate the pattern for Node.js-based MCP servers. ### References - [Model Context Protocol](https://modelcontextprotocol.io)
