Check the current authentication status.
AI agents call get_auth_status to retrieve information from Microsoft Graph MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool merely queries and returns the current authentication status. It performs a read-only operation without modifying, executing, or deleting any data. No irreversible actions or external command execution occurs. The low severity reflects minimal blast radius if misused — an agent checking auth status poses negligible risk.
From the tool's definition Tool named 'get_auth_status' with description 'Check the current authentication status' — retrieves authentication state information with no side effects.
Attacks that exploit this kind of access
Check the current authentication status. It is categorised as a Read tool in the Microsoft Graph MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Microsoft Graph MCP Server MCP server in PolicyLayer and add a rule for get_auth_status: 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 Microsoft Graph MCP Server. Nothing to install.
get_auth_status 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_auth_status 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_auth_status. 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_auth_status is provided by the Microsoft Graph MCP Server MCP server (sapientsai/microsoft-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
