Get information about the currently authenticated user.
AI agents call get_authenticated_user to retrieve information from GitHub MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries user information without modifying, deleting, or executing any external operations. It is a straightforward read operation that returns data about the authenticated user. The blast radius of misuse is minimal — an attacker gains only public/internal user profile information already accessible to authenticated API callers.
From the tool's definition Tool name is 'get_authenticated_user' and description states 'Get information about the currently authenticated user' — this is a retrieval operation with no side effects.
Attacks that exploit this kind of access
Get information about the currently authenticated user. It is categorised as a Read tool in the GitHub MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GitHub MCP Server MCP server in PolicyLayer and add a rule for get_authenticated_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 GitHub MCP Server. Nothing to install.
get_authenticated_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_authenticated_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_authenticated_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_authenticated_user is provided by the GitHub MCP Server MCP server (software-engineer-mj/github-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
