add_task · Mcp Tasks MCP: Risk & Policy

WHAT IT DOES

What add_task does on Mcp Tasks

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

WHY IT NEEDS A POLICY

Why add_task needs a policy

This tool creates a new record in the local SQLite database without deleting or overwriting existing data. The effect is reversible (tasks can be deleted), and there are no side effects outside the task tracker or financial implications. It is a straightforward Write operation with minimal blast radius—a misused agent would simply create unwanted tasks, which can be cleaned up.

From the tool's definition Tool name 'add_task' and description 'Insert a new task' indicate data creation. The action is reversible via delete_task.

Verdict

add_task Rate-limited

add_task 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.
