Use the product MCP address
CallUltra's remote Model Context Protocol (MCP) server belongs to your app account. Copy the server address from Developers → Connect to Claude & ChatGPT after signing in. For the hosted app, it is:
https://app.callultra.com/api/mcpConnect an assistant
- 1Open Developers in CallUltra
Sign in to the app, open Developers, and copy the MCP server URL shown in the connection panel.
- 2Add a remote MCP connection
In your assistant's connector settings, create a connection using that URL. Choose the account you intend to use.
- 3Sign in and review access
The assistant opens CallUltra's sign-in and consent flow. Read the requested permissions carefully before approving them.
- 4Check the connection
Ask a read-only question such as which agents are available. The connected app appears in CallUltra's Developers panel.
For ChatGPT, custom MCP connections are configured through its current developer-mode plugin flow where available. See OpenAI's current connection guide for the latest steps and account requirements.

get_agent | agents.read | Read one agent's configuration. |

Call transcript resource
With calls.read access, an MCP client can also attach a call transcript as a read-only resource. The resource template is spedrix://calls/{call_id}/transcript. Find the call ID with list_calls or get_call first. The URI uses the product server's current internal scheme; it is not a web URL.
Permissions and safe use
- A connection can see only the tools covered by its granted scopes and your CallUltra role. Read-only connections do not receive write tools in their tool list.
place_callrings a real phone and is billed.resume_campaigncan start dialing queued contacts, andsend_whatsapp_messagemessages a real number. Review these requests before allowing them.- The MCP connector cannot delete data, manage API keys, add funds, or change team and billing settings through these tools.
- Do not paste an API key into an assistant. The remote connector uses a separate sign-in and consent flow.
Review or disconnect a connection
Open Developers → Connect to Claude & ChatGPT in CallUltra to see connected apps and their granted scopes. Disconnect an app there to revoke its access. The server checks whether the grant is still active on each request, so a revoked connection stops working immediately.
