echo2 · Follow Plan MCP Server MCP: Risk & Policy

WHAT IT DOES

What echo2 does on Follow Plan MCP Server

AI agents call echo2 as a supporting operation in Follow Plan MCP Server workflows.

WHY IT NEEDS A POLICY

Why echo2 needs a policy

An echo tool performs no reads from external data stores, no writes, no execution of code, and no destructive or financial operations. It merely returns what was given to it, making it a rare 'Other' classification. Confidence is moderate because the description is minimal and 'approach 2' is unexplained, but the core function appears benign.

From the tool's definition 'Echo back the input (approach 2)' — the tool simply reflects input back to the caller with no data modification, execution, or external effects.
