SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Before invoking heavier Unity MCP tools, you need a fast way to confirm the CLI and SignalR transport are alive. This Skill provides a zero-dependency readiness probe that performs no I/O and no Unity API calls, so failures isolate transport issues rather than tool logic. ## Core Features & Use Cases - Readiness Probe: Returns 'pong' when called without arguments, confirming the MCP transport is responsive. - Echo Verification: Echoes any provided message string back verbatim, letting you validate round-trip serialization. - Latency Measurement: Pure echo with no side effects makes it ideal for timing round-trip latency before running heavier tools. - Use Case: Before running a batch of Unity editor commands in CI, call ping to confirm unity-mcp-cli connectivity and fail fast if the transport is down. ## Quick Start Ask the AI to run the ping system tool with an optional message to confirm the Unity MCP connection is alive.

Frequently Asked Questions about ping

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I check if unity-mcp-cli is connected and working?▼

Run the ping system tool via `unity-mcp-cli run-system-tool ping` with no input. If it returns 'pong', the MCP transport is alive and ready for heavier tool calls.

How to test SignalR connectivity before running Unity MCP tools?▼

Use the ping tool as a smoke test before invoking heavier tools. It performs no Unity API calls, so a successful echo confirms the SignalR transport layer is functioning.

What does the ping tool return when no message is provided?▼

It returns the string 'pong' in the result field. When a `message` string is provided, that message is echoed back verbatim instead.

Why is unity-mcp-cli not found when running ping?▼

The CLI is not installed or not on your PATH. Install it globally with `npm install -g unity-mcp-cli`, or prefix commands with `npx unity-mcp-cli` instead.

Can ping measure round-trip latency for the MCP transport?▼

Yes. Because ping performs no I/O and no Unity API calls, its execution time reflects pure transport overhead, making it suitable for measuring round-trip latency.
