WHAT IT DOES

What generate_call_graph does on Code2Flow MCP Server

AI agents use generate_call_graph to create or update resources in Code2Flow MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Code2Flow MCP Server environment.

WHY IT NEEDS A POLICY

Why generate_call_graph needs a policy

An AI agent can call generate_call_graph faster than any human can review — one bad instruction and it creates or modifies resources in Code2Flow MCP Server by the hundred, each call as confident as the last.
