MCP for AI assistants

One MCP server for ChatGPT, Claude and Cursor — no separate integrations.

FoxEra Calls is a standard remote MCP server. The same URL works in every MCP-compatible assistant, and tools that do not support MCP can use the REST API instead.

Why one server matters

If you use more than one AI assistant — ChatGPT for quick tasks, Claude for longer work, Cursor while you code — keeping separate integrations for each is a chore. Different credentials, different setup steps, different dashboards. It slows you down and doubles the places where something can break.

A standard remote MCP server solves this. You point each assistant at the same URL, sign in once per assistant, and every tool works the same way in all of them. Your leads, campaigns and transcripts live in one account, not spread across separate plugins.

How the FoxEra MCP server works across clients

FoxEra Calls exposes a single remote MCP endpoint at https://app.foxera.co.uk/mcp. Any assistant that supports remote MCP servers can connect to it. The server advertises the same set of tools — adding leads, listing campaigns, previewing costs, reading transcripts — regardless of which client is calling.

Authentication uses OAuth. The first time you connect from a new assistant, you sign in with your FoxEra account. After that, the assistant remembers the connection until you revoke it. Every action is logged against your account, so you always know which assistant did what.

If your tool does not support MCP at all, a REST API offers the same capabilities. See the developer guide for endpoints and examples.

Connecting from ChatGPT

In ChatGPT, open Settings > Connectors and add a new MCP server. Paste the URL https://app.foxera.co.uk/mcp, give it a name, and sign in when prompted. ChatGPT then shows FoxEra tools alongside its built-in ones.

From that point you can ask ChatGPT to add leads, preview a campaign, or read back who answered — all in natural language. The assistant calls the MCP tools behind the scenes and shows you the result. Learn more in the ChatGPT connection guide.

Connecting from Claude

Claude supports remote MCP servers on the web, on Desktop and in Claude Code. On the web, go to Customize > Connectors and add the FoxEra URL. On Desktop, open Settings > Connectors and do the same. In Claude Code, run:

claude mcp add --transport http foxera https://app.foxera.co.uk/mcp

All three surfaces share your FoxEra account, so leads and campaigns stay in sync whichever you use. For a full walkthrough, see how to add a remote MCP server to Claude.

Connecting from Cursor and other MCP clients

Cursor reads its MCP configuration from a JSON file. Add a remote server entry pointing at the FoxEra URL, save, and Cursor picks it up on the next session. The OAuth sign-in step is the same as in any other client.

Any other editor or agent framework that implements the MCP client specification can connect in the same way. The protocol is open, so you are not locked into one assistant. If you move from Cursor to another tool next year, the same server URL still works.

What if my tool does not support MCP?

Some automation platforms, custom scripts and older assistants do not speak MCP yet. For those, FoxEra offers a REST API with the same capabilities: add leads, launch campaigns, read results. You authenticate with an API key instead of OAuth, and the endpoints return JSON.

This means every AI tool you use — whether it supports MCP or not — can operate your calling account. The developer guide documents both the MCP server and the REST API side by side.

Safety: one account, one approval gate

Whichever assistant you connect, the same safety rules apply. No one is phoned until you confirm the exact headcount in a campaign preview. Every action — adding a lead, starting a campaign, reading a transcript — is logged with the assistant that triggered it. You can revoke any assistant's access at any time by changing your password or removing the connection.

This is the same approval gate described in the AI cold calling software overview: your assistant prepares the campaign, you approve, FoxEra's AI agents (Cass, Alex or Andrea) make the calls. The cost is from 12p per connected minute with no subscription, and new accounts start with £7 of free calling credit.

Frequently asked questions

Do I need a separate FoxEra account for each assistant?

No. One FoxEra account works with every assistant you connect. Leads, campaigns and transcripts are shared across all of them.

Is the MCP server free to connect?

Connecting is free. You only pay for calls — from 12p per connected minute — and new accounts get £7 of free calling credit to start.

Can I revoke access for one assistant without affecting the others?

Yes. Remove the connection in that assistant's settings. Your other connections remain active. Changing your FoxEra password revokes all connections at once.

What happens if my assistant does not support MCP?

Use the REST API instead. It offers the same tools — adding leads, launching campaigns, reading results — authenticated with an API key. See the developer guide.
