Validate the configured API token against GET /user.
AI agents call staticx_auth_check to retrieve information from StaticX 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 an authentication validation check by querying a user endpoint. The GET method and lack of any modification, creation, deletion, or execution semantics clearly place it in the Read category. The severity is low because it only retrieves authentication status and does not expose sensitive operations or data at scale. Confidence is high due to the explicit GET verb in the description.
From the tool's definition Tool description states 'Validate the configured API token against GET /user' — a GET request that retrieves user information for verification purposes with no side effects.
Attacks that exploit this kind of access
Validate the configured API token against GET /user. It is categorised as a Read tool in the StaticX MCP Server MCP Server, which means it retrieves data without modifying state.
Register the StaticX MCP Server MCP server in PolicyLayer and add a rule for staticx_auth_check: 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 StaticX MCP Server. Nothing to install.
staticx_auth_check 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 staticx_auth_check 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 staticx_auth_check. 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.
staticx_auth_check is provided by the StaticX MCP Server MCP server (madprodworks-coder/staticx-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
staticx_auth_check is one line of StaticX 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.
