mcp-ge

What problem does it solve?

This Skill solves the problem of reliably deploying and authenticating custom MCP servers for Gemini Enterprise Agent Designer without GE surprises like unsupported transports, broken OAuth flows, or cached tool schemas.

Core Features & Use Cases

• Org-policy and data-store setup: Handles the required Google Cloud org policy override and GE data store configuration needed to register an MCP server endpoint.
• OAuth identity + production-ready token behavior: Specifies environment variables, exact redirect URI matching, and a token endpoint that supports both authorization_code and refresh_token with sufficiently long-lived JWTs.
• GE-compatible MCP architecture constraints: Ensures tools are registered directly (no meta-tool indirection), uses StreamableHTTP only, and supports zero-parameter identity resolution via JWT-derived email.
• Deployment guidance for production pitfalls: Includes checklist items for scaling constraints (in-memory OAuth state), Cloud Run build context gotchas, and common GE UI/log symptoms.

Quick Start

Activate the mcp-ge skill when you need to deploy a new MCP server for Gemini Enterprise that uses StreamableHTTP and implements the required GE OAuth double-flow with a /token endpoint that supports refresh_token.
