WHAT IT DOES

What list_commits does on Gitlab Mcp

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

RISK

Why list_commits is rated Low

This is a straightforward read operation that queries and returns commit data. It has no side effects—it does not create, modify, delete, or execute anything. The filtering options are parameters for the read operation itself, not triggers for external actions. Blast radius is minimal as an AI agent can only retrieve existing information.

From the tool's definition Tool name 'list_commits' and description 'List repository commits with filtering options' indicate a query operation that retrieves commit history without modifying or executing anything.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_commits safely

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

list_commits Allowed

list_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": {
    "list_commits": {}
  }
}

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

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