Cdes Server

Cannabis Data Exchange Standard — Model Context Protocol Server

License: Apache-2.0 Python 3.12+ MCP

A public MCP server that exposes the Cannabis Data Exchange Standard (CDES) v1 JSON schemas, reference data libraries, and validation tools to AI agents and MCP-compatible clients.

What is CDES?

The Cannabis Data Exchange Standard is an open-source data standard for the cannabis industry, providing:

• 7 JSON Schemas — Strain, Terpene Profile, Cannabinoid Profile, Terpene, Certificate of Analysis (COA), Rating, Rating Aggregate
• 3 Reference Data Sets — Terpene Library (10 terpenes), Cannabinoid Library (9 cannabinoids), Terpene Color Palette (30 WCAG 2.1 AA colors)
• Validation Tools — Validate any cannabis data object against CDES schemas

Quick Start

Option 1: Use the Public Server (Recommended)

The CDES MCP Server is hosted publicly at https://mcp.cdes.world — no installation needed.

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "cdes": {
      "url": "https://mcp.cdes.world/sse"
    }
  }
}

VS Code (GitHub Copilot)

Add to .vscode/mcp.json in your project:

{
  "mcpServers": {
    "cdes": {
      "type": "sse",
      "url": "https://mcp.cdes.world/sse"
    }
  }
}

Cursor / Windsurf

{
  "mcpServers": {
    "cdes": {
      "url": "https://mcp.cdes.world/sse"
    }
  }
}

Health Check

curl https://mcp.cdes.world/health

Option 2: Run Locally (stdio)

Install from source for local/offline use:

git clone https://github.com/Acidni-LLC/cdes-mcp-server.git
cd cdes-mcp-server
pip install -e .
cdes-mcp-server

For local stdio transport, configure your MCP client:

{
  "mcpServers": {
    "cdes": {
      "command": "cdes-mcp-server",
      "args": []
    }
  }
}

Example Interactions

List all schemas

> Use the CDES server to list all available schemas

The CDES standard includes 7 schemas:
1. Strain — cannabis strain definition with type, effects, flavors
2. Terpene Profile — 21 named terpene measurements
3. Cannabinoid Profile — 13 cannabinoid measurements with computed totals
4. Terpene — individual terpene definition with CAS number, effects
5. COA — Certificate of Analysis with lab info, safety tests
6. Rating — user rating/review (CX extension)
7. Rating Aggregate — aggregated rating statistics

Validate data

> Validate this strain data against the CDES schema:
> {"id": "strain-001", "name": "Blue Dream", "type": "hybrid"}

✅ Valid! The data conforms to the CDES v1 strain schema.

Look up a terpene

> What is Myrcene? Use the CDES terpene library.

Myrcene (CAS: 123-35-3) is a monoterpene with an earthy, musky, herbal
aroma. It's the most common terpene in cannabis (~40% of strains).
Boiling point: 168°C. Key effects: relaxing, sedating, anti-inflammatory.
Found in mango, hops, lemongrass, and thyme.

Schema Structure

All schemas follow JSON Schema Draft 2020-12 with base URI:

https://schemas.terprint.com/cdes/v1/
