Get current user information
AI agents call get_current_user to retrieve information from Grafana MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool simply reads and returns information about the current authenticated user. It has no side effects, cannot modify data, execute code, or affect external systems. While user information could theoretically be sensitive, the read-only nature and lack of operational impact makes this a low-severity Read operation.
From the tool's definition Tool is named 'get_current_user' and described as 'Get current user information' — this is a retrieval/query operation that returns data about the authenticated user without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
Get current user information. It is categorised as a Read tool in the Grafana MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Grafana MCP Server 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 Grafana MCP Server. 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 Grafana MCP Server MCP server (quanticsoul4772/grafana-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
