[MCP] Crashlytics tools are not available for Unity projects

## Summary

When working in Cursor, there are no available Crashlytics MCP tools.
According to the docs , it's a known issue -
https://firebase.google.com/docs/crashlytics/ai-assistance-mcp#troubleshooting-faq

But still, i believe it should be tracked and handled soon.

## Bug Info

- **Affected Tool(s):**
- **MCP Client:**
- **Operating System:**

### Steps to Reproduce

1. Configure Firebase MCP according to the docs (Cursor)
2. Launch Cursor and observe the MCP list
3. List of tools doesn't include Crashlytics tools

No repository file or test is named. Start by reproducing the Firebase MCP setup in Cursor for a Unity project, then read the linked Crashlytics MCP troubleshooting FAQ and trace the relevant MCP entry point. Done means Crashlytics tools are listed and usable for Unity projects, with a regression check if the existing test structure supports one.
