FAQ

Frequently asked questions

01

What is the 'On-Behalf-Of' requirement?

Greenhouse requires write operations to be associated with a specific User ID for auditing. This ID is passed in the header to identify who performed the action.

02

Can I search for candidates by email?

Yes! Use the list_candidates tool and provide the email parameter to find a specific person's recruitment record and history.

03

How do I advance an application to the next stage?

The advance_application tool requires a valid application ID. It will automatically move the candidate to the next sequential stage defined in your job's workflow.

04

How does the OpenAI Agents SDK connect to MCP?

Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.

05

Can I use multiple MCP servers in one agent?

Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.

06

Does the SDK support streaming responses?

Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
