Gemini Tool-Use Training: 350+ Service Simulations (MCP)

• Created near-exact simulations of 350+ third-party services as MCP servers to train Gemini tool-use, replicating auth flows, endpoints, and edge cases.

• Built evaluation harnesses and golden test flows to iterate on reliability and reduce integration brittleness.

• Utilized ChromaDB and embeddings for semantic grounding on certain services, designed compact, efficient schemas.

• Composed multi-step LLM chains to coordinate actions across services with guardrails, retries, and robust error handling.
