Check authentication status, current mode, and available authentication methods
AI agents call passgage_auth_status to retrieve information from Passgage MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only tool that retrieves status information about the current authentication session. It does not modify state, execute operations, approve actions, or delete data. The worst-case misuse would be unauthorized discovery of available auth methods, which has minimal blast radius compared to approval or deletion tools also present on this server.
From the tool's definition Tool description states 'Check authentication status, current mode, and available authentication methods' — purely informational queries with no side effects, no data modification, no execution of commands or operations.
Attacks that exploit this kind of access
Check authentication status, current mode, and available authentication methods. It is categorised as a Read tool in the Passgage MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Passgage MCP Server MCP server in PolicyLayer and add a rule for passgage_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 Passgage MCP Server. Nothing to install.
passgage_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 passgage_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 passgage_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.
passgage_auth_status is provided by the Passgage MCP Server MCP server (passgage/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
