completeTodo · Remote MCP Server MCP: Risk & Policy

WHAT IT DOES

What completeTodo does on Remote MCP Server

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

WHY IT NEEDS A POLICY

Why completeTodo needs a policy

This tool updates data (changes a TODO's status) but is reversible since the sibling tool 'markIncomplete' can undo the change. It does not delete or destroy data (thus not Destructive), does not execute arbitrary code (thus not Execute), and does not involve financial transactions (thus not Financial).

From the tool's definition Tool named 'completeTodo' with description 'Make the TODO complete' modifies task state reversibly by marking an existing TODO item as complete.

Verdict

completeTodo Rate-limited

completeTodo stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
