Best MCP Gateways for Google Workspace Integration 2026

MCP gateways provide a governed connection between AI agents and Google Workspace services such as Gmail, Calendar, Drive, and Chat, adding authentication, authorization, audit logging, policy controls, and monitoring beyond standard API integrations. Typical implementations use OAuth, with service accounts or domain-wide delegation in some enterprise cases, and require enabling relevant APIs, configuring consent scopes and redirect URIs, and limiting access through role-based and resource-specific permissions. The comparison highlights MintMCP as a production-oriented gateway for deploying and governing MCP servers with SSO, SCIM-based access controls, tool-level policies, observability, and credential management; Google Workspace Studio as a fast no-code, Gemini-based automation option; Gemini Enterprise with ADK as a Google-centric platform for custom agents; and Boomi Agentstudio as a multi-cloud governance solution. Organizations can use these tools for governed email search and response workflows, feedback analysis, calendar scheduling, and other Workspace automation, but are advised to validate vendor certifications, data-residency practices, permissions, and reported business outcomes through security reviews and pilot deployments.
