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

VerifiedSSEWeb executableLocation & LifestyleKnowledge & MemoryBusiness & Commerce

Overview

AI-generated overview

Read-only MCP server for the French and European hemp/CBD market: product search, producer geolocation, market prices, legal and wiki reference.

What you can do
  • Search, compare and get recommendations for artisanal French CBD products, with live stock and shipping checks
  • Look up producers by city, postal code, department or region, with certifications, ratings and GPS
  • Read market price data per variety, trends and price checks, plus CBD news
  • Search and read a sourced FR/EN wiki encyclopedia, guides, myth-busting answers, country-by-country legality and terpene profiles
  • Explain how to read a certificate of analysis (CoA) for cannabinoids, THC thresholds and contaminants
  • Browse catalog, producer map and legal reference resources, and run discovery or producer-comparison prompts
When to use it
Useful when answering questions about French or EU CBD products, prices, local hemp producers, or CBD legality and health topics, and when you want sourced, read-only reference material rather than general web results.
Requirements
A remote Streamable HTTP endpoint; the README lists a public endpoint with no authentication. Self-hosting requires Node.js, npm install and SUPABASE_URL plus SUPABASE_ANON_KEY in a .env file.
Before you install
All tools are described as read-only, but the server logs anonymous per-tool calls (tool, parameters, result count, latency) and adds UTM tags to outbound links. Health, dosage and legality content is documentary, not medical or legal advice. The manifest lists an SSE endpoint while the README says that host is offline and points to a different HTTP endpoint, so verify the URL before connecting.

Installation

In SourceWeft

  1. Open LeBonFoin in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.POP24%2Flebonfoin-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

Herbe en France MCP Server

[License: MIT] [MCP] [Hosted] [EU]

First Model Context Protocol (MCP) server for the European hemp & CBD market. Exposes 1200+ artisanal French hemp farmers, real-time market prices ("Bloomberg CBD"), a live encyclopedia (sourced from Légifrance, PubMed, INRAE, AFPC), and producer geolocation to any MCP-compatible LLM (Claude, ChatGPT custom connectors, Cline, Cursor, …).

🌐 Live endpoint : https://www.herbeenfrance.com/mcp (Streamable HTTP, public, no authentication, all tools read-only) 📦 Marketplace : https://herbeenfrance.com 🏛️ Wikidata : Q139847939

curl https://www.herbeenfrance.com/mcp# {"name":"L'Herbe en France MCP Server","version":"1.8.0","transport":"streamable-http","tools":15,"resources":4,"prompts":2,...}

v1.8.0 (31/10/2026) : the hosted server moved from Railway (SSE, now offline) to the herbeenfrance.com app itself, on the Streamable HTTP transport, with readOnlyHint annotations on every tool. This repository keeps the stdio / SSE build for self-hosting.

📚 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, Cursor or any MCP client

  • Claude (web / desktop) : Settings → Connectors → Add custom connector → https://www.herbeenfrance.com/mcp
  • Claude Code : claude mcp add --transport http herbeenfrance https://www.herbeenfrance.com/mcp
  • Any client with a JSON config :
json
{  "mcpServers": {    "herbeenfrance": {      "type": "http",      "url": "https://www.herbeenfrance.com/mcp"    }  }}

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.
