Get the currently authenticated GitLab user.
AI agents call get_current_user_tool to retrieve information from MCP Gitlab without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about the currently authenticated user. It performs no data modification, deletion, code execution, or financial operations. The blast radius is minimal—an AI agent misusing this tool could only leak information about the current user's identity, which is typically already known in an authenticated session.
From the tool's definition Tool name 'get_current_user_tool' and description 'Get the currently authenticated GitLab user' indicate a read-only query operation that retrieves user identity information without modification or side effects.
Attacks that exploit this kind of access
Get the currently authenticated GitLab user. It is categorised as a Read tool in the MCP Gitlab MCP Server, which means it retrieves data without modifying state.
Register the MCP Gitlab MCP server in PolicyLayer and add a rule for get_current_user_tool: 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 MCP Gitlab. Nothing to install.
get_current_user_tool 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_current_user_tool 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_current_user_tool. 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_current_user_tool is provided by the MCP Gitlab MCP server (mcp-gitlab-crunchtools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
