Connecting Your Unreal Project

Cosindra talks to Unreal through a native C++ plugin — but you never install it yourself. Point the app at your project and it handles the rest.

The flow

  1. In the desktop app, click Select Project and pick your .uproject file — recent Unreal projects on the machine are auto-detected.
  2. The app detects the project’s engine version and fetches the matching prebuilt CosindraMCP plugin for your platform, then places it in the project’s Plugins/ folder. The binaries come prebuilt per engine version, so no compiler is needed — Blueprint-only projects work as-is.
  3. Launch the editor from the app. The bundled local bridge starts automatically alongside.
  4. Verify: the editor’s Output Log shows CosindraMCP: Connected to MCP Server!

Supported engine versions

Unreal Engine 5.7 and 5.8. Each engine version gets its own plugin build, resolved automatically per project — a UE 5.7 and a UE 5.8 project can sit side by side.

If the editor doesn’t connect

  • Check the engine version — projects outside UE 5.7/5.8 aren’t supported yet.
  • In the editor, open Edit → Plugins and confirm CosindraMCP is listed and enabled, then restart the editor.
  • Make sure the desktop app is running — it hosts the local bridge the plugin connects to.
  • Still stuck? Contact us with the Output Log lines around the CosindraMCP entries.
