Connecting AI agents to a live production app via MCP: hands-on setup guide
Original: I gave an AI agent the keys to a live production app: here's the MCP setup
Short summary
A hands-on guide for connecting AI agents to a live production app via a hosted MCP server, with setup instructions for Claude Code, ChatGPT, and Codex. The server exposes namespaced operation tools (cms_, shop_, classic_) with OAuth scoping, structured schemas, and server-side policy blocks that guide agents to verify writes. Real examples include scheduling push notifications and publishing articles through agent tool calls.
- •Hosted MCP server at GoodBarber lets agents operate a live mobile app via OAuth-scoped tool calls
- •Server returns _mcp_policy.verification_required on every write, instructing agents to read back results before declaring success
- •Setup covers Claude Code, ChatGPT, and Codex clients with SSE and Streamable HTTP transports
Generated with AI, which can make mistakes.
