Google's Colab MCP server was put through a demanding real-world test: an AI agent was tasked with building a complete quantum chemistry workflow from scratch inside a blank Google Colab notebook. The agent installed dependencies, resolved version compatibility errors (Qiskit V1/V2 primitives mismatch, transpiler plugin issues), ran a 15-point hydrogen molecule potential energy surface scan using VQE, and submitted a job to IBM's 156-qubit ibm_fez quantum processor. The experiment demonstrates that Colab MCP enables agents to actively operate cloud notebooks — creating cells, executing code, reading tracebacks, and iterating on fixes — rather than just reading them. The full debug cycle and actual IBM Quantum job submission are shown with real outputs.
