Check if authentication is configured for Sure API.
AI agents call check_auth_status to retrieve information from Sure MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves authentication status information and has no capacity to modify system state, execute code, or affect financial operations. It is a read-only diagnostic check with minimal security impact. The severity is low because even if an agent misuses this tool, it can only observe whether auth is configured, not perform unauthorized actions or access restricted data beyond this status flag.
From the tool's definition The tool 'check_auth_status' performs a status check on authentication configuration with no side effects.
Attacks that exploit this kind of access
Check if authentication is configured for Sure API. It is categorised as a Read tool in the Sure MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Sure MCP Server MCP server in PolicyLayer and add a rule for check_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 Sure MCP Server. Nothing to install.
check_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 check_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 check_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.
check_auth_status is provided by the Sure MCP Server MCP server (robcerda/sure-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
check_auth_status is one line of Sure MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
