WHAT IT DOES

What list_watchers does on GitHub Repos Manager MCP Server

AI agents call list_watchers to retrieve information from GitHub Repos Manager MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why list_watchers needs a policy

This tool only retrieves information about users subscribed to a repository. It has no side effects, does not modify data, and does not execute external operations. It falls squarely within the Read category as a data retrieval operation. The severity is low because inadvertent exposure of watcher lists poses minimal risk compared to destructive or financial operations.

From the tool's definition Tool name is 'list_watchers' and description states it 'List users watching/subscribed to the repository' — this is a query operation that retrieves repository metadata without modifying or executing anything.

POLICY

How to control list_watchers

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

policy.json

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

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