Return the user that owns the configured personal access token.
AI agents call get_current_user to retrieve information from GitLab MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about the authenticated user—a standard read-only operation. It queries existing data without creating, modifying, deleting, or executing any actions. The blast radius is minimal: the tool cannot be weaponized to cause harm beyond potentially exposing the authenticated user's identity, which is already implicit in token usage.
From the tool's definition Tool name 'get_current_user' and description 'Return the user that owns the configured personal access token' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
Return the user that owns the configured personal access token. It is categorised as a Read tool in the GitLab MCP MCP Server, which means it retrieves data without modifying state.
Register the GitLab MCP server in PolicyLayer and add a rule for get_current_user: 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 MCP. Nothing to install.
get_current_user 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 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. 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 is provided by the GitLab MCP server (shahabmosavi/gitlab_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
