Can Your AI Assistant Handle French Admin? MCP, Explained for Expats

Large language models are trained on a snapshot of the internet. French administrative reality is not a snapshot: the IRL rent-revision index changes every quarter, the zone tendue list is set by decree and covers over 1,400 communes, DPE-based rental restrictions tighten on a fixed calendar, and cross-border tax thresholds move with each Franco-Swiss avenant.

So when you ask a bare chatbot "can I raise the rent on my Bordeaux flat?", it reconstructs an answer from training data that may be a year or more old — and it phrases that reconstruction with exactly the same confidence as a verified fact. For casual questions that is annoying. For a rent revision letter, a tenant's notice period or a health-insurance election with a legal deadline, it is genuinely risky.

The fix is not a smarter model. It is giving the model a way to look the rule up in a source that someone maintains.

The Model Context Protocol is best understood as a universal socket. On one side: your AI assistant — Claude, Mistral's Le Chat, or any of the growing list of MCP-capable clients. On the other: a server that exposes specific tools, each with a name, typed inputs and a documented output.

Once connected, the assistant stops improvising on topics the server covers. Ask about a notice period and it calls the `notice period` tool with your commune and situation; the server computes the answer from the actual legal rule and hands it back; the assistant explains the result in your language.

Anthropic published MCP as an open standard in late 2024, and it has since become the de facto way to connect assistants to real systems — the major assistant vendors support it, and public directories list thousands of servers. The important shift for non-technical users: connecting one is no longer a developer task. It is a URL pasted into your assistant's connector settings.

AdminLanding (the operational-tools platform behind this site) runs a public MCP server with its French rental and France–Switzerland cross-border calculators. The free endpoint requires no account and no API key:

`https://api.adminlanding.com/mcp`

What it answers, once connected:

• Zone tendue lookup — "Is Annecy in a zone tendue?" (the decree list, not a guess)
• Tenant notice period — 1 or 3 months, computed from commune and circumstances
• DPE rental restrictions — what a G, F or E energy class means for your right to rent and raise rent
• IRL rent revision — "Revise a 850 € rent with the Q2 2026 IRL index", with the published index value
• Net Swiss salary — gross-to-net for a frontalier, canton by canton
• LAMal vs CMU — the health-insurance comparison behind the droit d'option
• Frontalier family allowances — which country pays what
• Geneva quasi-resident check — whether the status is worth electing

Every tool description is bilingual English–French, and every response carries provenance: the legal source and the data vintage it was computed from, so you can verify rather than trust.

The exact clicks vary by assistant, but the shape is the same everywhere:

1. Open your assistant's settings and find the section called Connectors, Integrations or MCP servers.
2. Choose to add a custom connector and paste the URL: `https://api.adminlanding.com/mcp`
3. Save. The assistant discovers the available tools by itself.
4. Ask a question the tools cover — "Am I in a zone tendue in Lyon?" — and watch it call the tool instead of guessing.

There is nothing to install and nothing to pay for the free tier. If you prefer to vet the server first, it is listed in the official MCP registry as well as the main public directories (Glama, Smithery, mcp.so).

One honest caveat: MCP support differs by product and sometimes by subscription plan. If your assistant has no connector settings, that is a limitation of the client, not of the server.

The free endpoint answers questions. The authenticated endpoint — `https://api.adminlanding.com/mcp/account` — turns answers into documents. You sign in with your AdminLanding account through a standard OAuth flow (your assistant shows a login screen; no password ever passes through the AI), and the toolset expands:

• Generate a quittance de loyer (rent receipt) for one of your properties — free
• Generate a lease or another rental document — 4.90 € as a one-off, or from a Rental Pack (50 documents for 49 €; the first property is free with 10 documents included)
• Send a document for electronic signature to your tenant, using the platform's EU-certified e-signature provider

Generated files are delivered through one-time download links, and the documents themselves are the same French legal templates the platform produces on the web — the assistant is a new front door, not a new document engine. The French document remains the legally binding version; the assistant just makes producing it conversational.

Connecting an AI assistant to an account that holds tenant data deserves scrutiny, so here is the boundary as it is actually enforced server-side:

• A connected assistant can read your own property list — enough to say "generate the June receipt for the Villeurbanne flat".
• It cannot read tenant personal data, your stored documents, or anything in the encrypted Vault. Those simply have no MCP endpoint.
• The free endpoint is anonymous and holds no account data at all.

Just as important is what the answers are. None of the tool results are AI-generated: the zone tendue list, the notice-period logic, the IRL math and the document templates are deterministic, maintained rule engines — the same ones behind the platform's web calculators. The AI in the loop is your assistant, doing what it is good at (understanding your question, explaining the result), while the legal substance comes from a source with a named maintainer and a stated legal reference on every response.

A connected assistant is dramatically more reliable on covered topics, but three limits are worth keeping in view:

• The assistant can still paraphrase badly. The tool returns the correct number; the model writes the sentence around it. Check the provenance line the tool attaches rather than the prose alone for anything consequential.
• Coverage is finite. Eight calculators and a document generator do not cover succession law, visa edge cases or your tax audit. Off-tool questions get the same old confident guessing — the connector does not make the model honest, it only gives it somewhere to look.
• Information is not advice. Like every calculator and template discussed on this site, tool results are legal information, not legal advice. Deadlines with real stakes — droit d'option elections, congé notices, tax elections — deserve a professional's review.

Used within those limits, this is the most meaningful change in expat-admin tooling in years: the assistant you already talk to every day can finally check the actual rule.
