Frequently asked questions
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.
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.
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.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
