OpenAI Connector

OpenAI API connector for model discovery, chat completions, and embeddings.

Credential setup

bearer

Create a dedicated API key with spend limits; chat and embedding calls require approval.

Setup docs: https://platform.openai.com/api-keys

After adding this connector, attach the credential on the server page, then run astrail tools list.

Hosted MCP endpoint

/api/mcp/preset-openai

Private servers require an Astrail API key in the Authorization header.

Astrail does not evaluate generated TypeScript inside Next.js. Hosted calls are routed through stored tool metadata and endpoint maps.

Tools

openai_list_models

openai_retrieve_model

Retrieve an OpenAI model by id.

openai_create_chat_completion

Create an OpenAI chat completion after approval because this incurs provider usage.

openai_create_embedding

Create OpenAI embeddings after approval because this incurs provider usage.
