addTodo · Remote MCP Server MCP: Risk & Policy

WHAT IT DOES

What addTodo does on Remote MCP Server

AI agents use addTodo 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 addTodo needs a policy

This tool creates new records in a database. It is a Write operation because it modifies data reversibly (todos can be deleted or updated later). Severity is medium because the blast radius depends on what an AI agent might add and how many records it creates; there is no authentication mentioned, increasing risk. Confidence is high because the name and description clearly indicate creation of database records.

From the tool's definition Tool name is 'addTodo' and description states 'Add TODO to the DB', indicating data creation/modification to a database.

Verdict

addTodo Rate-limited

addTodo 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.
