TL;DR: MCP (Model Context Protocol) is an open standard that connects an LLM to external tools. Formula.'s MCP server ships mid-July 2026. It makes your prospecting agent steerable in natural language from Claude, ChatGPT or Gemini: change targets, read replies, adjust the pitch, pull a numbers report. Message validation stays on mobile, one swipe, under 5 minutes.

What is MCP, in plain English?

MCP, short for Model Context Protocol, is an open standard that lets an AI model like Claude, ChatGPT or Gemini connect to external tools and data. Anthropic released it in late 2024, and OpenAI and Google adopted it in 2025, which made it the common language between LLMs and the rest of the software world.

The simplest analogy: MCP is to AI what USB-C is to your phone. Before, every tool had to build a custom integration for every AI assistant. With MCP, a tool exposes one standardized socket, and any compatible LLM can plug into it.

An MCP server is that socket on the tool's side. It declares a list of available actions ("read conversations", "update the target persona", "give this week's stats") and the LLM uses them when you ask in natural language. You never see an API or a line of code. You type a question in your usual chat, and the action runs.

Why does plugging your prospecting agent into your LLM change the game?

Because your AI salesperson becomes reachable from the tool you already open ten times a day. No extra dashboard, no extra login, no new interface to learn: you steer your outbound where you already work.

Until now, the rule of B2B software was simple: every tool imposes its own interface. Your CRM has one, your email tool has another, your LinkedIn tool has a third. The result: you spend your day hopping between tabs, and half the features never get used because they are buried three menus deep.

MCP flips that logic. The interface is the conversation. You type "show me the prospects who replied this week" and you get the list, with the context of each exchange. You type "narrow the target to HR consulting firms with 10 to 50 people" and the agent rebuilds its prospecting list starting the next morning.

For a prospecting agent like Formula., this is the missing link. The agent already works on its own: 28 LinkedIn invitations per day (the limit every tool on the market shares), parallel email follow-up on the same qualified prospects, pre-written replies you approve with a swipe. What was left to streamline was the steering: the strategic conversation between you and your agent. That is exactly what MCP unlocks.

"Your agent already prospects without you. Mid-July, you will also manage it without leaving Claude, ChatGPT or Gemini."

What will you actually be able to do from Claude or ChatGPT?

Everything related to configuring, monitoring and adjusting your Formula. agent. Here are the use cases planned for the mid-July release, all in natural language, without opening the app:

The underlying logic: you talk to your agent the way you would talk to a salesperson you manage. Except this one applies the instruction within a minute, across the 840 prospects it contacts every month.

Does the mobile swipe go away with MCP?

No. MCP and the mobile app are two different gestures for two different moments. The mobile app, shipping in July 2026, handles the daily gesture: approving pre-written replies with a swipe, in seconds, so the prospect gets your answer in under 5 minutes, 24/7. That response speed multiplies conversion by 100 compared to answering the next day.

MCP handles the steering: strategy discussions, configuration, analysis. You do not swipe from Claude, and you do not rebuild your persona from your phone while standing in line. Each channel does what it does best.

If the agent's underlying mechanics are still fuzzy (the 28 invitations per day, the parallel email on the same prospects, the 50-60% reply rate versus the market's 7-11%), the full LinkedIn agent guide covers it all.

When does it ship, and who is it for?

Formula.'s MCP server ships mid-July 2026, a few days after the mobile app. It is included in the subscription, at no extra cost, for every client with an active agent.

The prerequisite does not change: Formula. is built for consultants, advisory firms and B2B SMBs that already validated their sales manually over 3 to 6 months, from €5,000 in monthly revenue, with no ceiling. An agent, MCP or not, amplifies what already works. It does not validate an offer for you.

On the data side: nothing moves. Your prospects, conversations and statistics stay hosted in Paris, under GDPR. The MCP server exposes authenticated actions tied to your account, not raw database access. Claude, ChatGPT or Gemini only see what you ask for, when you ask for it.

Confirmed timeline: mobile app with swipe validation in July 2026, MCP server mid-July 2026, WhatsApp, Instagram and X channels later this summer. LinkedIn and email are already live today.

How do you get ready before mid-July?

The best preparation is having an agent already calibrated the day MCP ships. Calibration takes a few dozen seconds: the agent ingests your LinkedIn profile, your website and your offer, then starts prospecting. Clients who activate their agent now will have a history of conversations and data to work with from their very first MCP session.

The trial runs for 2 weeks. That is enough to see the first replies come in and judge on evidence. If you are still weighing tools, we published an honest comparison of AI prospecting agents in 2026: strengths and limits of each, including our own.

Frequently asked questions about the Formula. MCP server

Does the MCP server replace the Formula. app?

No. The MCP server is an additional entry point, not a replacement. The mobile app with swipe validation remains the core daily gesture for approving replies in under 5 minutes. MCP is for steering: configuring the agent, reading replies, adjusting targeting, requesting reports, all by chatting from Claude, ChatGPT or Gemini.

Do I need a paid Claude or ChatGPT plan to use the Formula. MCP server?

You need an account on at least one of the three LLMs (Claude, ChatGPT or Gemini) that supports MCP connectors. Paid plans on those tools give more reliable connector access. On the Formula. side, MCP is included in the subscription at no extra cost.

Is my prospecting data safe when accessed through MCP?

Yes. Formula. prospecting data (prospects, conversations, statistics) stays hosted in Paris, under GDPR. The MCP server exposes authenticated, permissioned actions, not raw database access. Every request runs through your account with the same rights you have in the app.

What will I actually be able to do from Claude or ChatGPT?

Change your target persona in natural language, read this week's prospect replies, adjust the agent's pitch by discussing it, request a numbers report (invitations, conversations, meetings) and review prospects waiting for validation. Everything related to setup and monitoring, without opening a dashboard.

Which LLM should I pick to steer my Formula. agent?

The one you already use every day. Formula.'s MCP server works the same way with Claude, ChatGPT and Gemini. That is the point of an open standard: your agent follows you into the LLM of your choice, instead of forcing a new tool on you.
