Why create_todo_list needs a policy

This tool creates new data (a todo list) in Basecamp, which is a reversible operation—todo lists can be deleted or modified later. It does not execute arbitrary code, delete data irreversibly, move money, or retrieve data.

From the tool's definition Tool name is 'create_todo_list' and description states 'Create a new todo list', which is a data creation operation. Basecamp is a project management platform where todo lists are core organizational data structures.

POLICY

How to control create_todo_list

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_todo_list": {
      "limits": [
        {
          "counter": "create_todo_list_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_todo_list 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.

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