WHAT IT DOES

What get_diff does on GitHub

AI agents call get_diff to retrieve information from GitHub without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why get_diff is rated Low

The tool purely retrieves information (the diff of an existing pull request) without creating, modifying, deleting, or executing any operations. It is a read-only query operation with minimal security impact even if misused.

From the tool's definition Tool name is 'get_diff' and description states 'Get the diff of a pull request' — this retrieves and displays differences between code versions with no modification or execution.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs get_diff safely

PolicyLayer is an MCP gateway: it sits between your AI agents and GitHub, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_diff, this is the rule to start with:

get_diff Allowed

get_diff is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect GitHub, apply this rule, and every get_diff call is checked against it from then on.
