DazPilot

Disclaimer: This plug‑in is not affiliated with, endorsed by, or sponsored by DAZ 3D.

MCP server for AI-driven DAZ Studio scene editing. Runs as a native DAZ Studio plugin (DLL) and exposes all scene control, rendering, dForce, asset, and animation commands through the Model Context Protocol.

How It Works

Claude Desktop  ──stdio──>  daz-mcp-client.py  ──HTTP POST /mcp──>  DazPilot (DLL inside DAZ Studio)

• The plugin hosts an HTTP server on 127.0.0.1:8765 serving a single endpoint POST /mcp
• Clients send JSON-RPC 2.0 messages with MCP methods: initialize, tools/list, tools/call
• Each command maps to DAZ Studio SDK calls executed on DAZ's main thread
• The Python shim daz-mcp-client.py translates MCP stdio transport to HTTP for Claude Desktop

196 Commands

All categories — scene, selection, properties, materials, morphs, cameras, lights, rendering, assets, animation, dForce simulation, poses, clothing, hair, environment, export, viewport, rigging, scripting, mesh queries.

Build

Prerequisites

• CMake 3.15+
• C++17 compiler (MSVC 2019+)
• DAZ Studio 4.5+ SDK (place the SDK in a folder named thirdparty at the repository root; obtain it from DAZ or your own source, it is not pulled automatically)

Quick Start

cmake -B build -DDAZ_SDK_ROOT="C:\Program Files\DAZ 3D\DAZStudio4\SDK"
cmake --build build --config Release

Header-only test build (no SDK):

cmake -B build -DBUILD_TESTS=ON
cmake --build build --config Release

Install

Copy DazPilot.dll to your DAZ Studio plugins directory:

C:\Program Files\DAZ 3D\DAZStudio4\plugins\

Restart DAZ Studio. The server starts automatically on port 8765.

Direct HTTP usage

If you prefer to talk to the MCP server directly (without the Python shim), you can POST JSON‑RPC requests to the plugin’s HTTP endpoint. The server runs at http://127.0.0.1:8765/mcp and follows the JSON‑RPC 2.0 specification.

Using curl

curl -X POST http://127.0.0.1:8765/mcp \
     -H "Content-Type: application/json" \
     -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'

The response will be a JSON object containing the list of available commands.

Using Python (requests)

import requests
payload = {"jsonrpc": "2.0", "id": 1, "method": "tools/list", "params": {}}
resp = requests.post('http://127.0.0.1:8765/mcp', json=payload)
print(resp.json())

Using JavaScript (Fetch API)

fetch('http://127.0.0.1:8765/mcp', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ jsonrpc: '2.0', id: 1, method: 'tools/list', params: {} })
})
  .then(r => r.json())
  .then(console.log);

All other methods described in the MCP Protocol section work the same way – just replace the method and params fields. The plugin will reply with a JSON‑RPC response containing either result or error.

{
  "mcpServers": {
    "dazpilot": {
      "command": "python",
      "args": ["path/to/daz-mcp-client.py"]
    }
  }
}

The shim forwards stdio JSON-RPC to http://127.0.0.1:8765/mcp.

MCP Protocol

The plugin implements Streamable HTTP transport:

• Endpoint: POST http://127.0.0.1:8765/mcp
• Content-Type: application/json
• Body: JSON-RPC 2.0 request object

Methods

Method	Purpose
initialize	Server capabilities & version
tools/list	List all 196 commands
tools/call	Execute a command

Example

{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"get_scene_info","arguments":{}}}
