MCP: the protocol that finally gives your AI a hand
A few months ago, a customer asked us if their AI could directly consult their Power BI reports to answer business questions. The technical answer was yes — but the road to get there was like a six-week construction site. Custom connections, authentication management, data format to be standardized... For each tool, we started from scratch.
That is exactly the problem that MCP is looking to solve.
AI is smart. But she is blind.
A language model like Claude or GPT is able to reason, synthesize, analyze. But he only sees what is given to him. Without access to your real data — your CRM, your ERP, your financial reports — it runs in a vacuum. It generates plausible text, not useful answers.
Until now, the solution was to develop custom connectors for each tool+model combination. Expensive, fragile, and not reusable. Each integration was a project in itself.
What is MCP exactly?
The Model Context Protocol is an open standard published by Anthropic at the end of 2024. Its objective: to define a common language between AI models and external tools.
The most accurate analogy is USB. Before USB, each manufacturer had its own connector. Afterwards, a single standard simplified everything.
The MCP does the same for the AI ecosystem: no matter the model, no matter the tool — if both speak MCP, they understand each other.
How does that work in practice?
The architecture is based on three components:
The customer — it's the AI model or the agent that needs information or actions.
The MCP server — it's the bridge you build (or install) on the tool side. It exposes “capabilities”: read an SQL table, retrieve a customer file, launch a calculation.
The host — it is the application that orchestrates the communication between the two (Claude Desktop, a custom agent, etc.).
Concretely: your model asks a question, the MCP server queries your database, returns the structured result, and the model integrates it into its response. All without having to rewrite the integration logic for each case.
What is changing for data and finance teams
The most immediate use cases are where data is rich but scattered.
In Business Intelligence, an agent connected via MCP to your Power BI semantic models can answer questions in natural language directly on your real KPIs — without exporting, without copying and pasting.
In Finance, imagine an assistant capable of consulting your ERP to check a budget balance, cross-check with a forecast file, and generate a variance comment. What took a manual half-day becomes a 30-second request.
In operations, an MCP agent connected to your CRM can qualify leads, update statuses, or prepare meeting minutes without human intervention on repetitive tasks.
It's not magic. It's clean automation, with an added layer of reasoning.
The limits you need to know
Let's be honest: MCP is still in its early stages.
Safety remains an open field. Giving an AI agent the ability to act in your real systems requires serious consideration of permissions, action logs and safeguards. It's not insurmountable, but it can't be improvised.
Adoption is fast but uneven. The big players (Anthropic, some software publishers) are moving quickly. The ecosystem of ready-to-use MCP servers is growing, but is still limited for very specific or legacy tools.
Finally, the complexity of implementation depends heavily on your existing stack. In modern and well-documented environments, it is accessible. On old systems, the background work remains substantial.
What to remember
MCP isn't revolutionizing AI—it's finally making it operational in your real environments.
What is changing is the friction.
Before : each AI-tool connection was a project.
After : it's a standard. And in a context where businesses seek to automate intelligently without exploding their IT budgets, reducing this friction has concrete value.
If you're working with business data and looking at AI from afar wondering how to integrate it without rebuilding everything — the MCP is worth your attention.
The door is open. It remains to be decided what to do there.
