🚀 Use it from Claude Desktop

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

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

Restart Claude. You can now ask :

"What's the average price of Amnesia CBD flower in France this month?"
"Find a hemp producer near Bordeaux, certified bio."
"What did the Conseil d'État decide about CBD flowers in 2022?"
"Recommend me a CBD oil for sleep, budget €40."
"What is the AFPC?"

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