Developer implements novel 'door credentials' for AI model authentication

By PulseAugur Editorial · [1 sources] ·

A developer encountered an unexpected authentication challenge when integrating multiple AI models with a new MCP server. The issue stemmed from the server's strict requirement for a specific token presentation, which some clients, like ChatGPT, Gemini, and Copilot, could not provide. To resolve this, a new system of "door credentials" was implemented, allowing each AI seat to use a unique, revocable secret presented in various formats, including URL parameters, while maintaining a single, consistent identity verification process on the server side. AI

    One MCP server, five auth shapes: per-seat door credentials when a client can't send a header

    <p>Here's a problem I didn't expect to be the blocker.</p> <p>I had three model seats — ChatGPT, Gemini, Copilot — already working against one MCP server (my Canonical Vault, which does no transport credential check; governance lives server-side in branch rules). Those surfaces c…
