ChatGPT / GPT Builder

Transport: OpenAPI Action
Authentication: API key (header X-Agent-Api-Key) — ChatGPT does NOT yet implement MCP transport.

Limitations

MCP transport is not supported in ChatGPT custom GPTs. Use the REST API via OpenAPI Action; the chatgpt-app PostMessage build runs at agenticmcpstores-production.up.railway.app and is for ChatGPT Apps SDK only, not Claude.ai.

Configuration — GPT Builder → Actions → Import OpenAPI

OpenAPI URL: https://api.trusteed.xyz/api/v1/openapi.json
Auth: API key, custom header "X-Agent-Api-Key"
