OpenAI / ChatGPT
chatgpt supports mcp connectors natively for business and enterprise accounts; for free / plus accounts, wrap the endpoint as a custom gpt action.
Option 1: MCP connector (business / enterprise)
settings → connectors → add → “custom mcp server” → point at the url below. mcp connectors on chatgpt require streamable-http, which domainposture.com speaks natively.
https://domainposture.com/mcp/mcpOption 2: Custom GPT action
custom gpts accept openapi 3.1 action definitions. wrap domainposture.com's mcp endpoint with a minimal relay (any function-as-a-service works) that exposes each tool as an http post action, or use one of the mcp-to-openapi proxies available on github.
Tools advertised
see the mcp landing page for the full list of 21 tools. all of them are callable from both flows above.
