Who's it for?

One profession, un cas d'usage réel

Plug OneMCP into your favourite AI. Six profiles, six ways to cross-reference your apps (Notion, Slack, Drive) with FR/EU business data in real time — from a single connector, no scraping, no maintenance.

💼
The business developer
Before a cold call, your agent enriches the prospect in seconds: SIREN, BODACC, LEI, risks — and pushes the record straight into Lemlist or Apollo through the vault's native connector.
🏘️
The real estate agent
Geocode the property address, pull the neighbourhood's DVF transactions and Géorisques natural hazards — the pricing argument is ready before the client meeting.
⚖️
The corporate lawyer
Cour de cassation case law, up-to-date Légifrance texts, BODACC procedures and VAT/LEI verification for KYC — one question, one sourced answer on current law.
📈
The M&A analyst
Express due diligence on a target: officers, financial history, insolvency procedures, public contracts won — the complete profile in a single prompt.
🔬
The strategy consultant
Map a competitor's R&D across 100M+ EPO patents, cross-reference it with DECP public contracts won in a territory — competitive intelligence without a dedicated subscription.
🎓
The business school student
Case study, dissertation or pitch: research a real company, its local property market, its legal situation — official data, free up to 1000 calls/month.
Data included

Comparison

One connector, not ten to maintain

FAQ

Frequently asked questions

Is the data up to date?

Recherche d'entreprises data is refreshed daily by DINUM. INSEE Sirene is updated D+1. DVF is refreshed quarterly. Cache TTL is configured per source (1 hour to 30 days depending on volatility).

Est-ce légal de revendre ces données ?

Yes, all Layer 1 sources are under Licence Ouverte 2.0 (Etalab) or an equivalent license allowing commercial reuse with source attribution. Provenance is included in every response. For personal data (officers), dates of birth are truncated to YYYY-MM (GDPR compliance).

Does my Notion, Slack or Drive data pass through your servers?

OneMCP relays the call to the service's API and returns you the response — it neither stores nor copies your content. Nothing is kept on OneMCP's side after the response: no database of your documents, no index, no reuse for training. Each tenant is isolated: a connector is only reachable with your own API key.

Where are my tokens stored, and how do I revoke them?

Your tokens are encrypted at rest in your vault and are never returned in clear text, not even to you — the dashboard only shows an input hint. They are used solely to sign calls to the service concerned. You delete a connector from the dashboard and access is cut immediately. For Notion and Google Drive (1-click OAuth), you can also revoke the authorisation directly from your Notion or Google account.

Qu'est-ce que le mode BYOK ?

Bring Your Own Keys: you bring your own API keys (INSEE, INPI, EPO…). All these services offer free access with an account. We only charge for the orchestration and normalisation layer, hence the 50% reduction.

Comment fonctionne le schéma canonique ?

Each source returns data in a different format. The canonical schema (Zod) normalizes everything into common fields: siren, legal_name, officers, financials… Les données brutes restent accessibles via _raw. La provenance (source, URL, licence, date) est incluse dans chaque réponse.

Peut-on l'utiliser en self-hosted ?

Yes. Install via npx for local stdio use, or use the hosted server at https://api.onemcp.fr/mcp. La configuration est documentée dans la documentation.

Compatible ChatGPT et autres LLMs ?

Yes. In addition to the MCP transport (stdio/HTTP), OneMCP exposes a compact spec for ChatGPT at https://api.onemcp.fr/openapi-gpt.json et la spec complète sur https://api.onemcp.fr/openapi.json. Même schéma, même clé API.
