description	Control Google Colab notebooks from Claude Code via Chrome extension. Execute cells, run terminal commands, read outputs, and manage GPU compute remotely.

SCBE Colab Bridge

Execute code on Google Colab from the Claude Code terminal via the Chrome extension bridge.

Prerequisites

1. Chrome is open with Claude-in-Chrome extension connected
2. A Colab notebook is open in a Chrome tab
3. The Colab runtime is connected (green checkmark visible)

Capabilities

Terminal Commands (PREFERRED — handles multi-line code)

1. Click into the Colab terminal panel (right sidebar)
2. Type any bash/python command
3. Press Enter
4. Read output via screenshot

# Simple command
python3 -c "import torch; print(torch.__version__)"

# Write a script file then run it (avoids indentation issues)
cat > /content/my_script.py << 'EOF'
import torch
# ... multi-line Python with proper indentation
EOF
python3 /content/my_script.py

Cell Execution (single-line only)

1. Click + Code button at (170, 84) in toolbar
2. Click into the new cell editor
3. Type single-line Python with semicolons (NO indentation)
4. Press Ctrl+Enter
5. Read output via JS: document.querySelectorAll('.output_text')

Cell Search (viewport-limited)

Inject ColabBridge then search:

window.ColabBridge.findCell('search text')  // only finds rendered cells
window.ColabBridge.readOutput(cellIndex)     // read cell output
window.ColabBridge.runtimeStatus()           // check runtime

Full Notebook Index

Use local copy at notebooks/spiralverse_protocol_training_generator.ipynb Cell index at artifacts/colab_bridge/notebook_cell_index.json

Known Limitations

Issue	Workaround
Multi-line code in cells gets wrong indentation	Use terminal or write to .py file first
Cell search only finds viewport-rendered cells	Use local notebook index for full search
Focus can shift from terminal to notebook editor	Always click terminal panel before typing
Colab lazy-loads cells	Scroll to cell before reading via JS
No GPU on free tier by default	Use Runtime > Change runtime type > GPU

Proven Bridge Pattern

1. mcp__claude-in-chrome__tabs_context_mcp (get tab ID)
2. mcp__claude-in-chrome__navigate (open Colab URL)
3. mcp__claude-in-chrome__computer screenshot (verify state)
4. mcp__claude-in-chrome__computer left_click (click terminal)
5. mcp__claude-in-chrome__computer type (enter command)
6. mcp__claude-in-chrome__computer key Enter (execute)
7. mcp__claude-in-chrome__computer wait 5 (wait for output)
8. mcp__claude-in-chrome__computer screenshot (read result)

Training Data Generation

Every Colab bridge interaction generates potential SFT data:

• Command sent -> output received = (instruction, response) pair
• Error encountered -> fix applied = (problem, solution) pair
• Cell executed -> result analyzed = (task, completion) pair

These can be exported to training/sft_records/ for model training.
