What should I use if I need to connect agents to databases and APIs?

If you need agents to connect to databases and APIs, you should typically use a tool layer / integration layer rather than letting the agent talk directly to everything.
Good options:
- Function calling / tools: Best if your agent framework supports it. Define safe, structured tools like:
query_database(sql)get_customer(id)create_ticket(data)
- Middleware / orchestration layer: A backend service that the agent calls, which then handles auth, validation, rate limits, and logging.
- API gateway or service wrapper: Expose databases and internal systems through clean REST/GraphQL endpoints instead of direct DB access.
- Workflow automation tools: If you need multi-step integration, use something like n8n, Zapier, Make, or LangChain/LangGraph-style tools.
Best practice:
- Don’t give the agent raw database credentials.
- Put access behind controlled tools with validation and permissions.
- Use read-only access where possible.
If you tell me your stack (e.g. Python, OpenAI, LangChain, FastAPI, Postgres), I can suggest the most suitable setup.
