UE-MCP by db-lyon: Unreal Engine MCP Server for Claude, Cursor and Other Apps

• One entry point to every Unreal Editor action

  Lets the assistant search for an action, read its parameters, then call it. Through it the assistant reaches about 30 areas of the editor, such as levels, Blueprints, materials, assets, animation and builds.

  Try: “Place a point light 300 units above the player start, warm white.”

• Runs a saved multi-step recipe from your project

  Runs, plans or lists named flows from the ue-mcp.yml file next to your project. A flow chains editor actions and can include shell commands, with optional rollback when a step fails.

  Try: “Run the build_and_check flow.”

Watch out for

• It can run Python and console commands in the editor

  execute_python, run_python_file and execute_command run code inside Unreal Editor. The docs call execute_python a gated last resort, but it is still reachable. Keep the project under source control. github.com

• Flows can run shell commands on your computer

  A flow written in ue-mcp.yml can include a shell step that runs any command through the system shell. Review flows before you let the assistant run them. github.com

• It can delete actors, assets and other content

  The catalog has many delete and remove actions across levels, assets and Blueprints. Turn on write guards and the source control guard in ue-mcp.yml, and commit before long sessions. github.com

• Setup copies a C++ plugin into your project

  The init and update commands deploy the bridge plugin, enable several Unreal plugins and compile on first launch. Run them on a project you can restore. github.com

• It can start, stop and restart the editor

  The editor actions control the Unreal Editor process, which can lose unsaved work. Save before asking for builds or restarts. github.com

• Feedback reports go to GitHub only after you approve

  By default the feedback action asks you, not the assistant, to approve the exact text before it posts a GitHub issue. The feedback mode setting also has an auto-approve option, so leave it on interactive. github.com

• The README config always fetches the newest release

  The manual config uses ue-mcp@latest with --min-release-age=0, so each start can pull a brand-new version. Pin a version if you want updates on your schedule. github.com

• Setup can add a Claude Code hook and skills

  npx ue-mcp init can optionally install Claude Code skills and a feedback prompt hook (a PostToolUse hook in Claude Code settings.json), and run a GitHub sign-in. Decline them if you only want the server. npx ue-mcp uninstall-hooks removes the hook. github.com
