VS Code¶
Prerequisite: complete the Unity package installation.
Install¶
Install Visual Studio Code and a Chat extension that supports local MCP servers.
Configure¶
Unity Biome MCP creates .vscode/mcp.json in the Unity project. The file uses VS Code's servers root and typed stdio entry.
Open the Unity project as the VS Code workspace, accept the local-server trust prompt when appropriate, and run the first connection check.
For user-level configuration instead, use the global configuration command with client key vscode. The packaged CLI writes the platform-specific user mcp.json.
Client-specific Troubleshooting¶
| Symptom | Action |
|---|---|
| Server is not listed | Run MCP: List Servers from the Command Palette and confirm .vscode/mcp.json is loaded |
| Server is not trusted | Review the generated command, then accept the workspace trust prompt |
| Configuration changed | Run Developer: Reload Window |
| Tools cannot reach Unity | Keep Unity open and follow connection diagnostics |
