MCPgraphy
MCPgraphy is a proxy for Model Context Protocol servers that maps tool states and blocks invalid agent calls.
MCPgraphy sits between an AI agent and any Model Context Protocol server. It passively reads touched resources before and after each call to build a behavior graph of observed states and outcomes. The proxy uses this graph to offer valid tool candidates, attach warning notes to risky calls, and block destructive actions before they reach the server. It persists decisions and graph data in a local SQLite file for auditing. Ready-made adapters include the filesystem and bundled simulators.
