Google opens Gemini Agent SDK with first-party MCP server registry
The Agent SDK ships with a curated MCP registry, native long-running task support, and managed memory tied to Vertex AI.
Google released the Gemini Agent SDK in public preview, marking its first opinionated framework since the deprecation of Vertex AI Agent Builder’s classic flows. The SDK is built around the Model Context Protocol (MCP) and ships with a curated registry of vetted MCP servers spanning search, filesystem, code execution, and identity.
What changed. A first-party Gemini agent framework with native long-running task support, a managed memory store integrated with Vertex AI, and a curated MCP registry.
Why it matters. Three of the four hyperscalers now provide a first-party agent framework. The MCP registry, in particular, lowers the operational burden of maintaining custom tool servers.
Builder takeaway. Treat the registry as a security review surface, not a free pass. Vetted does not mean audited; pin specific server versions and isolate by trust tier before exposing them to a customer-facing agent.
