create_todo · Math MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_todo does on Math MCP Server

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

WHY IT NEEDS A POLICY

Why create_todo needs a policy

This tool creates or adds a new todo item to a data structure, which is reversible (todos can be deleted or updated). This is a Write operation—it modifies state by inserting new data. The severity is low because todo management has minimal blast radius; misuse would only affect task lists, not critical systems, financial data, or irreversible deletions.

From the tool's definition Tool name 'create_todo' combined with sibling tools 'update_todo', 'delete_todo', and 'set_todo_tool_enabled' indicates a todo management system. The 'create_' prefix indicates data creation/addition. Description is empty, limiting certainty.

create_todo Rate-limited

create_todo 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.
