THE RISK

Critical Risk

Why todoist_comments needs a policy

The tool explicitly supports delete operations on comments, which is irreversible. Since the most severe applicable category applies, and deletion of comments cannot be undone, this falls under Destructive. Severity is medium as comments are relatively low-value data compared to tasks or projects, but misuse could still permanently remove important discussion history.

From the tool's definition create, read, update, delete comments with 15,000 character limit and file attachment support

POLICY

How to control todoist_comments

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Todoist, and nothing reaches the server without passing your rules. This is the rule we recommend for todoist_comments:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "todoist_comments"
  ]
}

todoist_comments disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Mcp Todoist — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
