Harbinger Health MCP Server is one of 37 APIs that [Harbinger Health](https://apis.io/providers/harbinger-health/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include MCP, Agents, Authentication, and WordPress.

A live Model Context Protocol server namespace published on Harbinger Health's own host at https://harbinger-health.com/wp-json/mcp/, exposing two servers - mcp-oauth-server and mcp-adapter-default-server - over POST/GET/DELETE. It is protected by a real OAuth 2.1 deployment: https://harbinger-health.com/.well-known/oauth-authorization-server returns RFC 8414 metadata (authorization code with PKCE S256, refresh tokens, public clients, client ID metadata documents) and https://harbinger-health.com/.well-known/oauth-protected-resource returns RFC 9728 metadata naming the MCP server as the protected resource with a single mcp scope. An anonymous tools/list JSON-RPC call returns HTTP 401 mcp_unauthorized, so the tool catalogue and its input schemas require an authenticated introspection; the tool set is almost certainly drawn from the WordPress Abilities API registered at wp-abilities/v1, which is likewise 401 to anonymous callers. This is a site-content agent surface, not a clinical or diagnostic one.
