Install

git clone https://github.com/azereki/ue-angelscript-mcp.git
cd ue-angelscript-mcp
npm install
npm link

npm install automatically builds via the prepare script.

Configure

Add to your project's .mcp.json:

{
  "mcpServers": {
    "ue-angelscript": {
      "command": "ue-angelscript-mcp"
    }
  }
}

That's it. The server auto-detects your project from the working directory.

Auto-detection

The server walks upward from cwd to find your project:

Game project — directory containing a .uproject file
Engine source tree — directory containing Engine/Plugins/Angelscript/

Once the project root is found, the editor binary is located automatically at Engine/Binaries/{platform}/UnrealEditor-Cmd.

Environment variable overrides

For non-standard layouts, set these in the .mcp.json env block or your shell:

Variable	Description
`UE_AS_PROJECT_PATH`	Path to UE project root
`UE_AS_EDITOR_CMD`	Path to `UnrealEditor-Cmd` binary
`UE_AS_EXTRA_SCRIPT_ROOTS`	Additional script directories (semicolon-separated)

Example with overrides:

{
  "mcpServers": {
    "ue-angelscript": {
      "command": "ue-angelscript-mcp",
      "env": {
        "UE_AS_PROJECT_PATH": "/path/to/my/project",
        "UE_AS_EXTRA_SCRIPT_ROOTS": "/shared/scripts;/mods/scripts"
      }
    }
  }
}

Documentation categories

as_get_context organizes 2,700+ lines of bundled reference docs into searchable categories:

Category	Covers
`scripting_basics`	Actors, components, UCLASS, UFUNCTION, BeginPlay
`language_fundamentals`	Types, containers, handles, casting, lambdas
`properties_events`	UPROPERTY specifiers, delegates, timers, input
`networking`	Replication, RPCs, net roles, authority
`testing`	Unit tests, integration tests, latent commands
`bindings`	C++ bindings, FUNC/METHOD macros, ScriptMixin
`advanced_features`	Hot reload, preprocessor, GAS, subsystems

Call with no arguments to see all categories. Use category for browsing or query for keyword search.

Development

npm run dev     # Watch mode (recompiles on save)
npm run build   # One-time build
npm start       # Run the server directly

Test interactively with MCP Inspector:
