AI agents call get_health to retrieve information from Refinex without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on naming convention, 'get_health' most likely retrieves health/status information about the refinex-mcp server or its AWS spot price arbitrage signal system. This is a read-only query operation with no side effects. Confidence is slightly lowered (0.75) due to the empty description, but the name strongly indicates a non-destructive information retrieval operation.
From the tool's definition Tool name 'get_health' with no description suggests a health check or status query operation typical of monitoring endpoints that retrieve system state without modification.
Attacks that exploit this kind of access
get_health. It is categorised as a Read tool in the Refinex MCP Server, which means it retrieves data without modifying state.
Register the Refinex MCP server in PolicyLayer and add a rule for get_health: 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 Refinex. Nothing to install.
get_health 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 get_health 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 get_health. 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.
get_health is provided by the Refinex MCP server (keithrawlingsbrown/refinex-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
