Bug: [Antigravity] Editing tools (add_cell, run_cell) fail to dynamically register after successful connection #50

Description

@hashib786

Describe the bug:
After successfully running the open_colab_browser_connection tool and seeing the "I have successfully re-established the connection" message, the MCP client (Cursor/Claude) does not list the other notebook editing tools (like add_cell, run_cell, etc.). The AI continues to say it doesn't have the tools to write directly to the notebook.

Steps to reproduce:
Configure colab-mcp in the MCP settings.
Open a Google Colab notebook in the browser.
Call the open_colab_browser_connection tool.
Attempt to ask the AI to "create code in colab".

Expected behavior:
After connection, the server should expose the full suite of notebook editing tools so the AI can write and run code directly.

Actual behavior:
The AI only sees the connection tool and suggests manual copy-pasting because it cannot find the hidden tools even after a successful handshake.

Environment:
OS: Windows 11
MCP Client: Google Antigravity
Browser: Chrome
