WHAT IT DOES

What compare_commits does on Code MCP Server

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

RISK

Why compare_commits is rated Low

Comparing commits is a non-destructive read operation that fetches and analyzes existing Git history without modifying any data or state.

From the tool's definition "Compare two commits with detailed analysis" — this is a read/query operation that retrieves and displays diff information between two Git commits

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs compare_commits safely

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

compare_commits Allowed

compare_commits 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": {
    "compare_commits": {}
  }
}

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

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