Check the current authentication status and session state.
AI agents call teams_status to retrieve information from Teams MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation to check authentication and session state. It retrieves information about the current state but does not create, modify, delete, or execute any actions. The blast radius of misuse is minimal—an attacker could only learn about the current authentication status, not access or modify Teams data or perform any operations.
From the tool's definition Tool name 'teams_status' and description 'Check the current authentication status and session state' indicate a query operation that retrieves status information without modification or side effects.
Attacks that exploit this kind of access
Check the current authentication status and session state. It is categorised as a Read tool in the Teams MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Teams MCP Server MCP server in PolicyLayer and add a rule for teams_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 Teams MCP Server. Nothing to install.
teams_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 teams_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 teams_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.
teams_status is provided by the Teams MCP Server MCP server (m0nkmaster/msteams-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
