AI Game Developer — GameDev MCP Server

NuGet Docker Image License

Engine-agnostic Model Context Protocol server shared by the game-engine MCP plugins:

It is a thin host over the NuGet packages com.IvanMurzak.McpPlugin.Server and com.IvanMurzak.ReflectorNet, where all the real server logic lives. The server bridges MCP clients (Claude, Cursor, Copilot, …) and an engine plugin over SignalR:

MCP client  <->  gamedev-mcp-server  <-> (SignalR) <->  engine plugin (Unity / Godot / Unreal)

There is no engine-specific code in this package — one server binary serves all three engine plugins. Tools, resources and prompts are provided dynamically by whichever engine plugin connects.

Not to be confused with AI-Game-Dev-Server — the cloud LLM/billing proxy. This project is the local MCP stdio/http proxy host.

Install

dotnet tool (this package)

dotnet tool install --global com.IvanMurzak.GameDev.MCP.Server
gamedev-mcp-server --port 8080

Typical MCP client configuration (stdio):

{
  "mcpServers": {
    "GameDev-MCP": {
      "command": "gamedev-mcp-server",
      "args": ["--port=8080", "--client-transport=stdio"]
    }
  }
}

Docker

docker run -i --rm -p 8080:8080 aigamedeveloper/mcp-server

Pre-built executables

Download the zip for your platform from Releases — gamedev-mcp-server-<rid>.zip for win-x64, win-x86, win-arm64, linux-x64, linux-arm64, osx-x64, osx-arm64 — unzip, and run:

./gamedev-mcp-server --port 8080 --client-transport stdio

Configuration

CLI arguments override environment variables.

Environment variable CLI argument Default Description
MCP_PLUGIN_PORT --port 8080 Client to Server to Plugin connection port
MCP_PLUGIN_CLIENT_TIMEOUT --plugin-timeout 10000 Plugin to Server connection timeout (ms)
MCP_PLUGIN_CLIENT_TRANSPORT --client-transport stdio Client to Server transport: stdio or streamableHttp
MCP_PLUGIN_IDLE_TIMEOUT_SECONDS --idle-timeout-seconds 28800 streamableHttp idle-session eviction window (8h, so a local session survives a working day)
MCP_AUTH --auth transport-dependent Authentication mode: none or oauth (stdio → none; http → oauth when issuer + public-url set)
MCP_AUTH_ISSUER --auth-issuer — OAuth authorization-server URL. Required for oauth
MCP_PUBLIC_URL --public-url — Canonical public URL / token audience. Required for oauth
MCP_BIND --bind loopback Bind address: loopback, any (0.0.0.0), or a specific IP
MCP_ALLOWED_ORIGINS --allowed-origins — Additional allowed browser Origins (comma/semicolon-separated)
MCP_LOG_LEVEL — Info Log verbosity floor: Trace, Debug, Info, Warn, Error, Fatal. Read by NLog, so it has no CLI equivalent

In stdio mode console logging is redirected to stderr so stdout stays clean for the MCP JSON stream.

The default level is Info. MCP_LOG_LEVEL=Trace dumps every MCP message body for debugging; it is very high volume and rotates server-log.txt down to a few minutes of retained history, so set it only while reproducing an issue.

Write a pinned, URL-only MCP client config for an AI agent from the terminal: gamedev-mcp-server configure --agent claude-code (or --agent codex --url https://ai-game.dev/mcp; configure --help lists all agents).

Compatibility

GameDev-MCP-Server McpPlugin.Server ReflectorNet Engine plugins
9.2.4 (current) 7.5.2 5.4.0 engine plugins on McpPlugin 7.x
8.0.3 (legacy) 6.11.0 5.3.1 engine plugins on McpPlugin 6.x

Any 9.x server needs an engine plugin built on McpPlugin 7.x (the instance-metadata handshake + oauth mode); McpPlugin 6.x plugins pair with the 8.0.3 line. Every 9.x release since 9.0.0 builds against a released McpPlugin.Server 7.x — for the exact pins of an intermediate version see its entry on Releases.
