add_task_tags · RTM MCP Server MCP: Risk & Policy

WHAT IT DOES

What add_task_tags does on RTM MCP Server

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

WHY IT NEEDS A POLICY

Why add_task_tags needs a policy

This tool creates or modifies task tags, which is a reversible data modification operation. It falls under Write rather than Read (it modifies, not just retrieves), Execute (it doesn't run arbitrary code), or Destructive (tag additions are reversible). Confidence is high despite empty description because the name and server context clearly indicate tag addition functionality.

From the tool's definition Tool name 'add_task_tags' indicates it adds/modifies tags on existing tasks. Server description states 'full API coverage for task manipulation, including priority settings, tags'.
