addTask · Knowledge MCP Server MCP: Risk & Policy

WHAT IT DOES

What addTask does on Knowledge MCP Server

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

WHY IT NEEDS A POLICY

Why addTask needs a policy

The tool creates new task entries in a version-controlled knowledge base. This is a Write operation because it modifies data reversibly—tasks can be edited, deleted, or archived later. It has medium severity because while task injection could clutter or misdirect a user's task list, the effects are reversible and don't cause financial harm or irreversible data loss.

From the tool's definition Tool name 'addTask' and description 'Add a new task to today' indicate creation of a new data entry in the knowledge base markdown files. This is a reversible write operation that creates content without deletion.

Verdict

addTask Rate-limited

addTask 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.
