Profile

I built MCPlexor to solve a token waste problem I kept running into with MCP-based agents.The Problem: MCP (Model Context Protocol) is great for giving LLMs access to external tools. But if you connect multiple servers (GitHub, Linear, Postgres, Slack), you end up with 40-50k tokens of tool definitions injected into every request – before the agent even does anything.On a 200k context model, that's 25% gone. On smaller models, it's worse. And most runs only use 1-2 tools.The Solution: MCPlexor sits between your agent and your MCP servers. Instead of loading all tool definitions upfront:Agent asks for a capability ("create an issue") MCPlexor routes to the right server using semantic matching

MCPlexor – MCP multiplexer that cuts agent context usage by 95% is positioned in show hn launch, a segment that rewards a clear, focused offering.

The company is listed at the Show HN launch stage of development.
