Show HN: PolyMCP Skills – Scalable Tool Organization for MCP-Based AI Agents

Curious how this integrates with LangGraph, specifically if these skills map to subgraphs. I've been managing context bloat by filtering tools manually, so I am wondering if the dynamic loading here actually lowers latency compared to that standard approach.

Hi thanks for the comment, Skills don’t map to LangGraph subgraphs; they just scope tool schemas per task. Latency gains come from smaller prompts (no large MCP schema serialization); if you already filter tools manually, the main benefit is simpler, reusable orchestration.
