What it reaches, and what it needs
What it connects to
Unverified means a mention in the server’s own description, not a citation. A wrong claim here costs nothing to correct and nothing to trust yet.
Maintenance
MCP server that gives AI coding agents (Claude Code, Cursor, etc.) full control over Unreal Engine 5.7 projects — headless builds & tests, Blueprint editing, actor manipulation, procedural mesh generation, and UE API documentation lookup.
What mcp-unreal can do
27 tools documented in its README. An AI client calls these by name.

list_tests- List available automation test names matching a filter pattern.
get_test_log- Read raw UE log files with line limits, offsets, and keyword filtering.
get_level_actors- List all actors in the current level with class, path, location, rotation, and other properties.
spawn_actor- Spawn a new actor in the current level with specified class and location.
move_actor- Move an existing actor in the current level to a new location.
set_property- Set a property on an existing actor in the current level.
get_property- Get a property value from an existing actor in the current level.
blueprint_query- Query Blueprints for variables, functions, and nodes.
blueprint_modify- Modify Blueprints by adding, removing, or changing nodes, variables, and functions.
compile- Compile modified Blueprints.
material_ops- Create, modify, and manage materials.
save_level- Save the current level.
pie_control- Control Play In Editor (PIE) sessions.
capture_viewport- Capture the viewport during a PIE session.
player_control- Control the player pawn in a PIE session.
get_camera- Get the current camera position and rotation in a PIE session.
set_camera- Set the camera position and rotation in a PIE session.
lookup_docs- Lookup UE API documentation.
