DAML Coder MCP Server

Model Context Protocol server for DAML Coder AI - bringing AI-powered DAML development to Claude Desktop, VSCode, Cursor, Zed, and other MCP-compatible applications.

Version: 1.1.0
Model: DAML Coder v1.1.3

Developed by Tenzro Labs

Installation

npm install -g @tenzro/daml-coder-mcp

Or install locally in your project:

npm install @tenzro/daml-coder-mcp

Quick Start

1. Get an API Key

2. Configure Your Editor

Claude Desktop

Add to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "daml-coder": {
      "command": "daml-coder-mcp",
      "env": {
        "DAML_CODER_API_KEY": "YOUR_API_KEY_HERE"
      }
    }
  }
}

VSCode

Add to .vscode/mcp.json or your global settings:

{
  "mcpServers": {
    "daml-coder": {
      "command": "npx",
      "args": ["@tenzro/daml-coder-mcp"],
      "env": {
        "DAML_CODER_API_KEY": "${env:DAML_CODER_API_KEY}"
      }
    }
  }
}

Enable agent mode: Set chat.agent.enabled to true in VSCode settings.

Cursor

Add to Cursor settings:

{
  "mcp.servers": {
    "daml-coder": {
      "command": "npx",
      "args": ["@tenzro/daml-coder-mcp"],
      "env": {
        "DAML_CODER_API_KEY": "your-api-key-here"
      }
    }
  }
}

3. Restart Your Editor

Completely quit and reopen your editor. The MCP server will appear as a local integration.

Usage

Simply ask your AI assistant in natural language. The MCP server automatically selects the right tool:

Generate contracts:

Generate a DAML Token template with Transfer choice

Create an Escrow contract with buyer, seller, and arbiter

Build a CIP-0056 compliant token with two-step transfer pattern

Explain concepts:

What are consuming choices in DAML?

Explain the difference between signatories and observers

How does Canton Protocol v7 handle smart contract upgrades?

Debug code:

I'm getting error: Choice Transfer is consuming but does not archive self

Help me fix this authorization issue: [paste code]

Review this DAML contract for security vulnerabilities

Available Tools

The MCP server provides six tools that your AI assistant uses automatically:

generate_daml_code - Generate DAML smart contracts from natural language descriptions
review_daml_code - Comprehensive security review and analysis
explain_daml_concept - Get detailed explanations of DAML concepts and patterns
debug_daml_error - Debug errors with AI-powered root cause analysis and fix suggestions
generate_daml_tests - Automatic generation of comprehensive Daml.Script test cases
chat_with_daml_coder - Conversational AI assistant with context awareness

Supported Applications

Claude Desktop - Native MCP support
VSCode (v1.99+) - Agent mode with MCP tools
Cursor - Full MCP integration
Zed Editor - Built-in MCP support
Windsurf - MCP compatible
Cline - VSCode extension with MCP
Any MCP-compatible client

Troubleshooting

MCP server not appearing

Verify config file location and JSON syntax is correct
Ensure API key is set correctly (no quotes if using environment variable)
Completely quit your editor (not just close the window)
Check for typos in the server name and command

For Claude Desktop: Check logs at ~/Library/Logs/Claude/mcp*.log (macOS)

For VSCode: Open Command Palette → "MCP: List Servers" to see registered servers

API key errors

# Verify your API key is set
echo $DAML_CODER_API_KEY

# Test API connectivity
curl -H "Authorization: Bearer $DAML_CODER_API_KEY" \
  https://api.damlcoder.tenzro.network/health

Ensure your API key is valid and properly set in the config. Contact [email protected] if you need a new key.

Tool not being called

The MCP server should invoke tools automatically when you ask DAML-related questions. Make sure you're:

Asking clear, DAML-specific questions
Using agent mode (in VSCode)
Have the DAML Coder tools enabled in the tools picker

Connection issues

# Test the MCP server directly (if installed globally)
daml-coder-mcp

# Should show:
# DAML Coder MCP Server v1.1.0 running
# Using DAML Coder Model v1.1.3
# Ready to assist with DAML development!
