MCPlex intelligently routes only the tools your agent actually needs. --- The Problem Every developer building multi-agent AI systems with MCP hits the same wall: Pain Point Impact ----------- -------- 🧠 Context Bloat 20+ MCP servers = 50k+ tokens of tool definitions consuming your context window 🔓 No Security No RBAC, no audit trails, tool poisoning vulnerabilities 👁️ Blind Operations Can't track costs, latency, or debug wrong tool selection 🔄 Restart Required Config changes require full restart in production 🕸️ N×M Complexity Orchestrating dozens of servers is an integration nightmare The Solution MCPlex is a single-binary Rust gateway that sits between your AI agent and MCP servers: Transport Support MCPlex supports both MCP transport types as a first-class citizen: Transport Discovery Runtime Calls Connection Model ----------- ----------- --------------- ----------------- Stdio ✅ Full MCP handshake ✅ Multiplexed JSON-RPC Persistent child process (long-lived) Streamable HTTP ✅ Full MCP handshake ✅ Standard HTTP POST Stateless (connection pooling) Stdio servers are spawned at startup and kept alive for the gateway's lifetime. The MCP handshake ( initialize → notifications/initialized ) runs once, then all subsequent tools/call , resources/read , and prompts/get requests are multiplexed over t","default_branch":null,"files":null,"tree":[],"storefront":"/r/ModernOps888","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/ModernOps888/mcplex/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
