What it took to ship a production remote MCP server with OAuth 2.1

Minds shipped a production remote MCP server with OAuth 2.1 for its synthetic market research platform.

The server was connected to multiple clients, including ChatGPT, Claude, Cursor, and Google Antigravity, to test interoperability.

The team documented practical lessons on transport URLs, response formats, OAuth discovery, and live tool schemas.

They also highlighted durable job handling and research limits for building reliable agent workflows over remote MCP.

The launch underscores the real operational challenges of exposing MCP services across different client ecosystems.
