## Description
First MCP for the European hemp & CBD market: real French CBD catalogue, producers, FR/EN wiki

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "lebonfoin": {
    "command": "npx",
    "args": ["-y","lebonfoin"]
  }
}
```

## 📚 Wiki encyclopedia

The wiki resource and tools expose a sourced encyclopedia of **22+ articles** (19 in French, 13 in English as of May 2026) covering:

- **Cannabinoids** : CBD, CBG, CBN (FR + EN), THC (in progress)
- **Health & Legality** : French regulation, EU Novel Food, Conseil d'État decisions, CJUE Kanavape, NPS / synthetic cannabinoids
- **Botany & chemistry** : trichomes, terpenes, entourage effect, extraction methods
- **French industry** : artisanal farmers, AFPC, InterChanvre, history of French hemp
- **Strategic context** : *Strategy Parmentier* (patient pedagogy, scientific demonstration, regulatory cooperation)
- **Institutions** : AFPC, InterChanvre, MILDECA, DGAL, INRAE
- **Recent events** : Plan de contrôle DGAL 2026 sur le chanvre alimentaire

**Sources** : Légifrance · PubMed · INRAE · AFPC · MILDECA · EUR-Lex · Wikipedia FR/EN · Conseil d'État

Each article is timestamped, versioned (Wikipedia-style revisions), and cross-referenced. YMYL articles (health, legal) carry an automatic disclaimer. **English articles** are accessible via the same wiki tools and resources — slugs follow the convention `<fr_slug>-en` and hreflang is set bidirectionally for SEO.

## 🚀 Use it from Claude Desktop

Add to `~/Library/Application Support/Claude/claude_desktop_config.json` :

```json
{
  "mcpServers": {
    "lebonfoin": {
      "url": "https://lebonfoin-mcp-production.up.railway.app/sse",
      "type": "sse"
    }
  }
}
```

Restart Claude. You can now ask :

**French queries** :
- *"Quel est le prix moyen de l'Amnesia CBD en France ce mois-ci ?"*
- *"Trouve un producteur de chanvre près de Bordeaux, certifié bio."*
- *"Où acheter du CBD en Dordogne (24) ?"*
- *"Recommande-moi une huile CBD pour le sommeil, budget 40 €."*

**English queries (v1.5.0+ — uses `lang: "en"` automatically when relevant)** :
- *"Is CBD legal in Germany? What about Switzerland?"* → `cbd_legal_by_country({country: "DE", lang: "en"})`
- *"How do I read a Certificate of Analysis from a French hemp producer?"* → `cbd_lab_analysis({lang: "en"})`
- *"Is CBD addictive? What does the WHO say?"* → `debunk_cbd_myth({topic: "addictive", lang: "en"})`
- *"What is the entourage effect?"* → `get_wiki_article({slug: "effet-d-entourage-en"})`
- *"What are the main hemp terpenes?"* → `get_wiki_article({slug: "terpenes-du-chanvre-en"})`

The MCP server **automatically responds in the calling LLM's apparent language** when the tool supports `lang` — no manual switching required for the user.

Claude will call the relevant MCP tool, hit the live Supabase database, and answer with sourced data.
