Frequently asked questions
Where do I find my API Token?
Your API Token can be found in your Placetel web portal under Integrations > Web API.
What access does this MCP need?
It requires the REST API Token, giving access to users, calls, numbers, and devices.
Can I initiate phone calls using this server?
Currently, this integration supports retrieving Placetel data like CDRs and configurations. Call initiation via CTI will be added in a future update.
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.
