health_check
AI agents call health_check to retrieve information from SpeechPulse without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
A health_check tool typically retrieves or verifies the operational status of a system without modifying any state. Despite the empty description lowering confidence slightly, the name strongly indicates a read-only diagnostic operation. This carries minimal risk if misused by an AI agent, as it merely reports system state.
From the tool's definition Tool name 'health_check' suggests a status query operation with no side effects. Description is empty, but naming convention is consistent with non-destructive monitoring utilities.
Attacks that exploit this kind of access
health_check. It is categorised as a Read tool in the SpeechPulse MCP Server, which means it retrieves data without modifying state.
Register the SpeechPulse MCP server in PolicyLayer and add a rule for health_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 SpeechPulse. Nothing to install.
health_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 health_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 health_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.
health_check is provided by the SpeechPulse MCP server (sophiemiao/speechpulse). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
