Check if the MCP server is running properly
AI agents call health_check to retrieve information from GASSAPI 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 health/status probe that retrieves system state without modifying, deleting, or executing any workflows or endpoints. It falls squarely into the Read category as it merely queries the operational status of the server. The blast radius of misuse is minimal; an AI agent calling this repeatedly causes no harm beyond minor resource overhead.
From the tool's definition Tool description states 'Check if the MCP server is running properly' — a diagnostic query operation with no side effects. The verb 'check' indicates information retrieval only.
Attacks that exploit this kind of access
Check if the MCP server is running properly. It is categorised as a Read tool in the GASSAPI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GASSAPI MCP Server 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 GASSAPI MCP Server. 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 GASSAPI MCP Server MCP server (martin-1103/mcp2). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
