FAQ

Frequently asked questions

01

Can I verify if a non-profit is eligible for tax-deductible donations?

Yes! Use the verify_charity_status tool with the organization's EIN. Your agent will fetch the real-time compliance status from Candid's Charity Check API.

02

How do I find the EIN for an organization if I only have its name?

Simply ask the agent to search_nonprofits and provide the name. The search results will include the EIN for each matching organization, which you can then use for deeper lookups.

03

Does the integration allow accessing diversity and inclusion data?

Yes. Use the get_demographics tool. It will retrieve the DEI metadata provided by the organization to Candid, helping you understand their leadership and staff representation.

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.
