# OpenCrab
**MetaOntology OS MCP Server Plugin**
> Carcinization is the evolutionary tendency for crustaceans to converge on a crab-like body plan.
> OpenCrab applies the same principle to agent environments:
> all sufficiently advanced AI systems eventually evolve toward ontology-structured forms.
OpenCrab is an MCP (Model Context Protocol) server that exposes the MetaOntology OS grammar
to any OpenClaw-compatible agent environment — Claude Code, n8n, LangGraph, and beyond.
