WHAT IT DOES

What list_webhooks does on Gitlab Mcp

AI agents call list_webhooks 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_webhooks is rated Low

This is a read-only operation that retrieves webhook data. It performs no side effects, creates no resources, executes no code, and does not delete or modify data. The blast radius of misuse is minimal—an agent could enumerate webhooks to understand notification flows, but cannot trigger destructive actions through this tool alone.

From the tool's definition Tool name 'list_webhooks' and description 'List webhooks for a project or group' indicate a retrieval operation that queries existing webhook configurations without modifying them.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_webhooks 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_webhooks, this is the rule to start with:

list_webhooks Allowed

list_webhooks 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_webhooks": {}
  }
}

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_webhooks call is checked against it from then on.
