Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| UNREAL_VERSION | No | UE version to serve (e.g., '5.5', '5.7', '5.7.3'). Default: 5.7 | |
| UNREAL_INSTALL_PATH | No | Override UE install path (only used for ingest/local build) | |
| UNREAL_PROJECT_PATH | No | Path to Unreal project directory to auto-detect version from .uproject file |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| search_unreal_api | Search the Unreal Engine API by keyword. Args: query: Search terms (class name, function name, or keyword). n_results: Number of results to return (1-20, default 10). member_type: Filter by type: "class", "struct", "enum", "function", "property", or "delegate". Leave empty for all. |
| get_function_signature | Get the exact signature of an Unreal Engine function by fully-qualified name. Args: fqn: Fully-qualified name like "AActor::GetActorLocation" or "UGameplayStatics::SpawnActor". |
| get_include_pathA | Get the #include path for an Unreal Engine class, struct, or type. Args: name: Class or type name (e.g. "AActor", "FHitResult", "ECollisionChannel"). |

TDQS
Scored across 3 tools
Each tool has a clearly distinct purpose: retrieving class members, checking deprecation status, and getting include paths. No overlap or ambiguity.
All tool names follow a consistent 'get_<action>' pattern with clear noun suffixes ('reference', 'warnings', 'path'), making them predictable and easy to understand.
Three tools is an appropriate size for a focused API query server. Each tool addresses a common developer need without adding unnecessary complexity.
The tools cover core use cases for Unreal Engine API exploration, but could benefit from additional functionality like searching for APIs or listing available classes. Still, the surface is functional and satisfies the stated purpose.
