Why list_timelines needs a policy

This tool performs a read-only operation that queries and returns a list of existing timelines. It has no side effects, does not modify data, execute code, delete resources, or involve financial operations. The blast radius of misuse is minimal—an AI agent could only retrieve information about timelines that already exist in the project.

From the tool's definition Tool name 'list_timelines' and description 'List all timelines in the current project' indicate a query operation that retrieves information without modifying state.

How to control list_timelines

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_timelines": {}
  }
}

list_timelines is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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