2. Define bootstrapper config and build your application:

from fastmcp import FastMCP
from lite_bootstrap import FastMcpBootstrapper, FastMcpConfig


bootstrapper_config = FastMcpConfig(
    service_name="microservice",
    service_version="2.0.0",
    service_environment="test",
    sentry_dsn="https://testdsn@localhost/1",
    prometheus_metrics_path="/custom-metrics/",
    health_checks_path="/custom-health/",
    logging_buffer_capacity=0,
)
bootstrapper = FastMcpBootstrapper(bootstrap_config=bootstrapper_config)
application: FastMCP = bootstrapper.bootstrap()


@application.tool
def greet_person(person_name: str) -> str:
    return f"Hello, {person_name}!"

Set logging_turn_off_middleware=True on the config to disable the per-MCP-message access log middleware. Set health_checks_enabled=False to omit the health route.

Teardown is wired through FastMCP's provider lifecycle — bootstrapper.teardown() runs automatically when the FastMCP server's ASGI lifespan shuts down (i.e. when the application that serves application.http_app() shuts down).
