Topcalls Now Works With Claude, ChatGPT and Your Terminal

Your calls, campaigns and leads used to live in one place: the Topcalls dashboard. Now 18 tools let you ask about them in Claude, in ChatGPT, or from a terminal. Topcalls now works with Claude, ChatGPT and your terminal through an MCP server and a command line tool, both live today.

Key Takeaways

• The Topcalls MCP server gives AI apps 18 tools: 10 that only read your data and 8 that can change things.
• Claude and ChatGPT connect by pasting one server address and signing in to Topcalls. No API key is copied anywhere.
• A read only connection can look at calls, campaigns and leads, and cannot launch, pause or change anything.
• A connection that sits unused for 30 days ends by itself, and you can end any connection earlier in Topcalls settings.
• The Topcalls CLI runs the same tools from your terminal and asks before any command that changes data.

1. What does it mean that Topcalls works with Claude and ChatGPT?

It means an AI app you already use can read your Topcalls account when you allow it. Topcalls runs an MCP server, a standard way for AI apps to talk to other software. You connect Claude or ChatGPT once, then ask in plain language: how did yesterday's campaign do, what did this lead say on the call.

Nothing is copied out of Topcalls into a spreadsheet first. The AI app asks Topcalls, and Topcalls answers from your live account. The full list of what it can do is on the Topcalls MCP server page.

2. What can an AI app do with my Topcalls account?

An AI app connected to Topcalls can use 18 tools. Ten only read: they show your balance, calls, call transcripts, campaigns, leads, lead counts by status, phone numbers and Integrations flows. Eight can change things: save a campaign draft, launch, pause, resume or cancel a campaign, start a test call, import leads and run an Integrations flow.

Here are three questions people ask the read tools:

• Calls: "Which calls from this morning ended without an answer?" The AI app lists calls, newest first, with status, cost and summary.
• Campaigns: "Is my reactivation campaign still running, and how many leads are left?" It reads the campaign and its lead lists.
• Leads: "How many leads are New, Contacted and Converted?" It counts leads by status.

3. How do I connect Claude or ChatGPT to Topcalls?

You paste one address and approve the connection in Topcalls. In Claude, open Settings, then Connectors, and choose Add custom connector. In ChatGPT, add a custom MCP server and set authentication to OAuth. Both send you to Topcalls to sign in, pick the account and approve.

There's no API key to copy and no token to paste. ChatGPT gets every tool except the two Integrations tools. The exact address and each step, including Claude Code, Cursor and Codex, are in the setup documentation.

4. What is read only mode, and when should I use it?

Read only mode is a switch on the approval screen. A read only connection can look at your calls, campaigns and leads but cannot change anything: no launching, no pausing, no imports. Use it whenever the question is "what happened", which is most of the time.

Turn it off only when you want the AI app to act, like saving a campaign draft. Even then a launch is refused when the launch checklist is incomplete, the safety review fails or your credit is too low.

5. How do I stay in control of what an AI app does?

You stay in control through the approval screen, limits and an end switch. Each connection belongs to one account. Launches, test calls and lead imports have hourly and daily caps, resumes have an hourly cap, and every AI app connected to the account counts toward the same caps. No tool changes prices, adds credit or touches billing settings.

You can end one connection or all of them in Topcalls settings, and the app stops on its next request. A connection also ends after 30 days without use. The security model is explained on the MCP server page.

6. What is the Topcalls CLI?

The Topcalls CLI is an npm package, @topcalls/cli, that runs the same tools from your terminal. It needs Node.js 20 or newer. You sign in with a browser, so it never asks for a password, and a command that changes data shows the account and the arguments, then asks before it runs.

One command, topcalls agent setup, can also add the Topcalls MCP server to Claude Code, Cursor, Codex and VS Code on your computer, after asking. Install steps and every command are on the Topcalls CLI page.

7. When is this not the right tool?

Use the dashboard, not an AI app, for work that needs your eyes on every step: writing and testing a campaign script, reviewing a call recording, or setting up billing. The MCP server doesn't return call recordings, and it never changes billing.

An AI app also can't promise the same answer twice, because it words things its own way. For anything an auditor will read, export the data from Topcalls. The AI voice agents still do the calling. The AI app is a new way to ask about it and steer it.

8. How do I get started?

Start with read only. Connect Claude or ChatGPT from the MCP server page, ask three questions about last week's calls, and see whether the answers match what you know. If you run lead-heavy campaigns, lead qualification is a good first thing to ask about.
