AI agents call get_group to retrieve information from Gitlab without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns group data. It has no side effects, does not modify any resources, and poses minimal risk if misused by an AI agent. Classification as Read is appropriate.
From the tool's definition Tool name is 'get_group' and description states 'Get details of a specific group' — retrieves group information without modification.
Documented attack patterns abuse exactly the kind of access get_group gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Gitlab, and nothing reaches the server without passing your rules. This is the rule we recommend for get_group:
{
"version": "1",
"default": "deny",
"tools": {
"get_group": {}
}
}get_group is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get details of a specific group. It is categorised as a Read tool in the Gitlab MCP Server, which means it retrieves data without modifying state.
Register the Gitlab MCP server in PolicyLayer and add a rule for get_group: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Gitlab. Nothing to install.
get_group is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_group rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_group. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_group is provided by the Gitlab MCP server (yoda-digital/mcp-gitlab-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
