Check which services are currently authenticated.
AI agents call check_authentication_status to retrieve information from Activity Collector MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns the current state of authentication across integrated platforms (GitLab, GitHub, Google Calendar, Outlook Calendar). It performs no modifications, deletions, code execution, or financial transactions. It is purely informational and read-only in nature, making it a Read category tool with low severity.
From the tool's definition The tool 'check_authentication_status' retrieves the authentication status of integrated services. The description explicitly states it 'Check[s] which services are currently authenticated' - a query operation with no side effects or data modifications.
Attacks that exploit this kind of access
Check which services are currently authenticated. It is categorised as a Read tool in the Activity Collector MCP MCP Server, which means it retrieves data without modifying state.
Register the Activity Collector MCP server in PolicyLayer and add a rule for check_authentication_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 Activity Collector MCP. Nothing to install.
check_authentication_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 check_authentication_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 check_authentication_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.
check_authentication_status is provided by the Activity Collector MCP server (srdmathur/activity-collector-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
