One MCP server for cold calling, usable from any AI assistant.
FoxEra Calls exposes a standard remote MCP endpoint. Connect ChatGPT, Claude, Cursor or any MCP-compatible agent and run campaigns by chatting.
What this MCP server does
FoxEra Calls runs a remote MCP server at a single URL. When your AI assistant connects to it, the assistant gains the ability to manage your cold calling: add leads, choose a calling agent, preview and approve campaigns, read call transcripts and recordings, and pull cost reports. The calls themselves are made by FoxEra's named AI calling agents (Cass, Alex or Andrea), not by the assistant.
The server follows the standard remote MCP protocol (Streamable HTTP with OAuth 2.1), so any assistant that supports custom connectors or remote MCP servers can use it without extra code.
Which assistants can connect
Any assistant that supports the remote MCP protocol or custom connectors. That currently includes:
- ChatGPT (Plus, Team, Enterprise) via custom connectors
- Claude (Pro, Team) via custom connectors, and Claude Code or Claude Desktop via remote MCP server
- Cursor and other code editors that support MCP
- DeepSeek-based agents, n8n, Make and any tool that can call a Streamable HTTP MCP endpoint
If your tool does not support MCP but can make REST calls, FoxEra Calls also offers API keys (bearer tokens starting fxk_) and an OpenAPI 3.1 spec that works with GPT Actions. See the developer guide for both options.
The tools the server exposes
Once connected, your assistant can use these tools inside a normal conversation:
| Tool | What it does |
|---|---|
| Account status | Check your balance, credit and workspace details |
| Add leads | Add contacts one by one or upload a folder |
| Choose agent | Pick Cass, Alex or Andrea for the campaign |
| Preview campaign | See headcount, calling window and estimated cost before approving |
| Approve campaign | Confirm the headcount and start the calls |
| Read outcomes | Pull transcripts, recordings, cost and call status |
| Calling hours | Set or change the hours calls go out |
| Edit pitch | Update or approve the script the agent follows |
| Top-up link | Get a payment link to add credit |
How to connect in three steps
- In your assistant, find the option to add a custom connector or remote MCP server. Paste this URL: https://app.foxera.co.uk/mcp
- Sign in with your FoxEra Calls account when redirected. If you do not have one, you can create it on the spot with £7 of free calling credit.
- Press Allow. Your assistant now has access to your workspace.
Nothing to install, no server to host, no webhook to configure. The endpoint is already running.
The safety rule: no call without your approval
FoxEra Calls enforces a two-step check before anyone is phoned. The assistant must confirm the exact number of people to call, and a separate approval must be given. Every assistant is told to show you these figures and wait for your yes. You cannot be billed for calls you did not approve.
Every action taken through the MCP server is logged in your workspace. Keys and connectors act only inside your own account. You can revoke access at any time, and changing your password disconnects all connected assistants immediately. Learn more about how FoxEra Calls handles safety.
What it costs
Connecting to the MCP server is free. You pay only for calling: from 12p per connected minute, with no subscription, no seat fee and no minimum spend. Every new account starts with £7 of free calling credit.
Whether you connect one assistant or five, the pricing is the same. For a full breakdown, see the pricing page. To estimate a campaign before you run it, try the cost calculator.
Frequently asked questions
What is an MCP server in plain terms?
It is a standard way for an AI assistant to connect to an outside service. Instead of you switching between apps, the assistant talks to FoxEra Calls directly and acts on your instructions.
Do I need to host anything?
No. The MCP server is already running at app.foxera.co.uk/mcp. You just paste the URL into your assistant's connector settings.
Can one account be used from multiple assistants?
Yes. You can connect ChatGPT, Claude and any other MCP-compatible assistant to the same FoxEra account. They all see the same leads, campaigns and results.
Is the MCP server free to use?
Connecting is free. You pay only for calling, from 12p per connected minute with no subscription. New accounts start with £7 of free credit.
What if my tool does not support MCP?
FoxEra Calls also provides API keys and an OpenAPI 3.1 spec. Any tool that can make a REST call or use GPT Actions can connect. See the developer guide.
