Choosing an MCP Client

MCP for Unity auto-configures every client the package detects on your machine. The differences below decide which one fits your workflow.

Capability matrix

Client	Transport	Auto-config	Streaming reasoning	Free tier	Notes
Claude Desktop	stdio only	yes	yes	yes (rate-limited)	Easiest setup. Stdio is silently chosen even if HTTP is selected globally.
Claude Code	HTTP	yes	yes	needs Anthropic plan	First-party. Strong with multi-tool workflows.
Cursor	HTTP	yes	yes	partial	Requires an MCP toggle in Cursor's own settings after auto-config.
VS Code (Copilot)	HTTP	yes	yes	with Copilot	Configures under servers (not mcpServers).
Windsurf	HTTP	yes	yes	yes	Auto-connects after config.
Cline	HTTP	yes	yes	yes	Auto-connects after config.
GitHub Copilot CLI	HTTP	yes	yes	with Copilot	Terminal-based agent.
Codex	HTTP	yes	yes	with OpenAI	Auto-connects.
Qwen Code	HTTP	yes	yes	yes	Auto-connects.
Gemini CLI	HTTP	yes	yes	yes	Auto-connects.
OpenClaw	HTTP / stdio	yes	yes	yes	Requires openclaw-mcp-bridge plugin enabled. Follows MCP for Unity's transport choice.
Antigravity	HTTP	yes	yes	varies	Requires an MCP toggle in Antigravity settings.

How to pick

• You want it to just work: Claude Desktop. Stdio means no port conflicts and no firewall prompts.
• You're building a multi-agent or remote workflow: anything HTTP. Multiple clients can share one Python server; see Multi-Instance Routing.
• You're already in your IDE: Cursor, VS Code Copilot, or Cline — keeps you in flow.
• You want a terminal: Claude Code, Copilot CLI, Codex, Gemini CLI, or Qwen Code.

Manual configuration

If auto-config doesn't run (offline machine, sandboxed install, etc.), copy the snippet under Manual MCP client configuration in Install into your client's MCP config file.

Per-client toggle locations

A few clients need an MCP toggle flipped on after the configurator writes their config. Find it here:

• Cursor → Settings → MCP → enable the unityMCP server
• Antigravity → Settings → MCP servers → enable
• OpenClaw → enable the openclaw-mcp-bridge plugin

Everything else just connects on next launch.

When you update the package

Run Window → MCP for Unity → Configure All Detected Clients any time. It's safe to re-run — the configurator writes idempotently.
