## OpenAPI

````yaml /api-reference/openapi.yaml post /api/prescriptions/{id}/pharmacy
openapi: 3.1.0
info:
  title: Arlo Health MCP Server
  version: 1.0.0
  description: >
    Healthcare infrastructure for AI agents. Everything an agent needs

    to act in healthcare for its user.


    ## Overview


    This server exposes two interfaces:

    - **MCP** (Model Context Protocol) over streamable HTTP at `/` for AI agents

    - **REST API** at `/api/*` for bots, skills, and direct HTTP clients


    Both interfaces use the same tool handlers and authentication.


    ## Authentication


    OAuth 2.1 with PKCE. All `/api/*` endpoints require a Bearer token.


    Discovery endpoints (no auth required):

    - `/.well-known/oauth-protected-resource`

    - `/.well-known/oauth-authorization-server`

    - `/.well-known/mcp.json` (MCP Server Card)


    ## Service Regions


    Available in Ontario, Canada (`CA-ON`) and California, United States
    (`US-CA`).
