[gcgoncalves]

🐞 Bug Summary

The tables show more rows per page than allowed, and new pages are not created.

🧩 Affected Component

Select the area of the project impacted:

• mcpgateway - API
• mcpgateway - UI (admin panel)
• mcpgateway.wrapper - stdio wrapper
• Federation or Transports
• CLI, Makefiles, or shell scripts
• Container setup (Docker/Podman/Compose)
• Other (explain below)

---

🔁 Steps to Reproduce

1. Access the Admin UI
2. Make sure you have more than 10 servers registered (add them on the MCP Registry if needed)
3. Click the MCP Servers tab
4. Check the number of rows on the table versus the size of the page

This is one example, but applies to all tables.

🤔 Expected Behavior

The number of rows displayed should be the same as the page size, and then more pages should be enabled.
