WHAT IT DOES

What mee_reason does on memro MCP Server

AI agents invoke mee_reason to trigger actions in memro MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why mee_reason needs a policy

This tool executes a reasoning operation on internal data structures (knowledge graph) whose effects depend on the query argument provided. It is not a simple Read (which would be passive retrieval), nor Write/Destructive (no data modification stated), nor Financial. The execution of a reasoning engine with variable query inputs fits Execute.

From the tool's definition Tool description states 'Trigger the Memory Evolution Engine to reason about a specific query' — the verb 'Trigger' and reference to executing a reasoning engine indicates this tool runs a process that executes logic on internal knowledge structures based on…
