Why get_changeset_details needs a policy

This tool performs a read-only query to fetch changeset information. It does not create, modify, delete, or execute any operations. The use of 'Retrieve' in the description and the 'get_' prefix are characteristic of Read category tools. The blast radius of retrieving changeset details is minimal, as it only exposes existing data without enabling destructive or executable actions.

From the tool's definition Tool name is 'get_changeset_details' and description states 'Retrieve full details for a single changeset' — this is a retrieval operation with no modification or side effects.

POLICY

How to control get_changeset_details

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_changeset_details": {}
  }
}

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

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