Frequently asked questions
Can I post a status with a content warning (spoiler text)?
Yes. When using the post_status tool, you can provide a spoiler_text string which will act as a content warning for your followers.
How do I verify if my access token is working correctly?
You can use the verify_credentials tool. It will test your current token and return your authenticated profile information if successful.
Is it possible to see what is currently trending on my instance?
Absolutely. Use the get_trending_tags tool to retrieve the most popular hashtags used on your instance recently.
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.
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.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
