Get health status of the FastAPI application
AI agents call get_health to retrieve information from FastAPI 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 query/retrieval operation that returns diagnostic information about the application's health. It does not modify, delete, execute commands, or commit financial transactions. It is purely informational and read-only, consistent with standard health check endpoints.
From the tool's definition Tool named 'get_health' with description 'Get health status of the FastAPI application' — retrieves application status information with no side effects.

Get health status of the FastAPI application. It is categorised as a Read tool in the FastAPI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the FastAPI MCP Server 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 FastAPI MCP Server. 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 FastAPI MCP Server MCP server (teeps-heisenberg/mcp-server-fast-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
