WHAT IT DOES

What check_gitlab does on Mcp Nettools

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

RISK

Why check_gitlab is rated Low

This is a health check that retrieves status information about a GitLab instance without side effects. It queries the application state but does not create, modify, delete, or execute anything. The operation is read-only and non-intrusive, making it a Read category tool with low severity since even unauthorized access only reveals that a service is running.

From the tool's definition Tool performs a GET request to /-/health endpoint to confirm GitLab application is running and can accept requests. No data modification, deletion, or code execution occurs.

RECOMMENDED RULE

The rule that runs check_gitlab safely

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

check_gitlab Allowed

check_gitlab 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": {
    "check_gitlab": {}
  }
}

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

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