An MCP server that places real sales calls, priced per minute.
FoxEra Calls gives any AI assistant the tools to originate UK sales calls with a named agent, read transcripts and manage campaigns. Pay only for connected minutes.
What this server does differently
Most MCP servers that handle communication stop at email or chat. FoxEra Calls originates real phone calls. Your AI assistant tells FoxEra who to call and when; a named AI calling agent (Cass, Alex or Andrea) picks up the phone, introduces your business, answers basic questions and records the full conversation. The assistant then reads back outcomes, transcripts and cost.
The calls are real UK outbound calls, made during the hours you set, with the UK calling rules handled for you. This is not a text-to-speech demo or a simulated dial. Prospects hear a voice and have a conversation.
Who this is for
Founders and small teams who want to add outbound sales calls to the tools they already use. If you work from ChatGPT, Claude, Cursor or a custom agent built on n8n, Make or your own code, you can now add real phone calls to your workflow without building a telephony stack or paying for a monthly seat.
It also suits developers building agents that need to originate calls as part of a larger pipeline, for example an agent that researches prospects, writes a pitch and then calls them with your approval. The developer guide covers the technical detail: Streamable HTTP, OAuth 2.1, API keys and an OpenAPI 3.1 spec.
The tools your assistant gets
Once connected, your assistant can:
- Check your account status and credit balance
- Add leads individually or as a folder of contacts
- Choose the AI calling agent for the campaign
- Preview the campaign: headcount, calling window and estimated cost
- Approve the campaign after you confirm the number of people
- Cancel or stop a live campaign immediately
- Read call outcomes, transcripts, recordings and total cost
- Set calling hours so calls only go out when you want
- Edit and approve the calling script
- Get a top-up link to add credit
For a complete reference, see the developer guide. The OpenAPI spec is at https://app.foxera.co.uk/api/public/openapi.json for tools that use GPT Actions or REST directly.
Pay-as-you-go pricing with no seat fee
Calls cost from 12p per connected minute. There is no monthly subscription, no seat fee, no setup charge and no minimum spend. Whether one assistant connects or five, the pricing stays the same. New accounts start with £7 of free calling credit, so you can test a short campaign before spending anything.
You are billed only for connected minutes, which means time when the prospect actually picks up and a conversation happens. Unanswered dials, voicemails and busy signals do not count toward your bill. Compare the numbers on the cost-per-minute page or estimate a campaign with the cost calculator.
Safety: every campaign needs your approval
Before anyone is phoned, two conditions must be met. The exact number of people to be called must be confirmed, and a separate approval step must be completed. Every assistant is told to show you these figures and wait for your yes.
Every action taken through the server is logged inside your workspace. API keys and connectors act only within your own account and can be revoked at any time. Changing your password disconnects everything. FoxEra Calls is built for outbound sales automation in the UK, with the rules and controls that entails.
Getting started
- In your AI assistant, add a custom connector or remote MCP server. Paste: https://app.foxera.co.uk/mcp
- Sign in with your FoxEra Calls account (or create one with £7 of free credit).
- Press Allow. Your assistant can now manage your calling.
If your tool uses REST instead of MCP, generate an API key inside the FoxEra dashboard and use the OpenAPI spec. Both routes reach the same tools and the same workspace. See the AI sales calling agent page for more on what the agents can do.
Frequently asked questions
Does the MCP server actually place phone calls?
Yes. When your assistant approves a campaign through the server, FoxEra's AI agents dial real UK phone numbers, have live conversations, and record every call. This is not a simulation.
Which AI assistants work with this server?
Any assistant that supports remote MCP or custom connectors: ChatGPT, Claude, Cursor, DeepSeek-based agents, n8n, Make, and custom code. REST API keys are also available for tools that do not support MCP.
Can an assistant spend my credit without asking?
No. FoxEra Calls requires you to confirm the exact headcount and approve the campaign separately. The assistant cannot bypass this step.
Do I pay a monthly fee?
No. Calls cost from 12p per connected minute with no subscription and no seat fee. New accounts start with £7 of free credit.
