RingDNA MCP Server is one of 2 APIs that [RingDNA](https://apis.io/providers/ringdna/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include MCP and AI Agents. The published artifact set on APIs.io includes authentication docs.

A live, remotely hosted Model Context Protocol server operated by Revenue.io at https://app.ringdna.com/mcp. An MCP client can POST to it today with no local install. It is protected by OAuth 2.1 with PKCE (S256) and advertises the full modern discovery chain - RFC 9728 protected resource metadata, RFC 8414 authorization server metadata, and RFC 7591 dynamic client registration, which returns 201 to an anonymous POST. The server is entirely undocumented: it appears nowhere in the 753-page Revenue.io Knowledge Center, nowhere in the marketing llms.txt, and in no release note through July 2026. It was found by probing the well-known surface. Its tool list is auth-gated (tools/list returns HTTP 401 with a bearer challenge) and is deliberately not recorded rather than guessed.
