Acrisure Authentication

generated: '2026-08-06'
method: probed

description: >-
  Acrisure publishes no OpenAPI, so this profile is not derived from securitySchemes. It is
  read directly from the RFC 8414 authorization-server metadata that api.acrisure.com
  serves anonymously, plus the observed 302 from /oauth/authorize. The single protected
  resource this covers is the hosted MCP server at https://api.acrisure.com/v1/mcp.

notes:
- >-
  The authorization and token endpoints are Acrisure-branded proxies on api.acrisure.com;
  /oauth/authorize 302s to
  login.microsoftonline.com/c2ec94c0-ebd0-4630-aef2-2dcf0eb68ebd, so the actual
  authorization server is Microsoft Entra ID and the tenant is Acrisure's own.
- >-
  Client registration is not self-serve. There is no dynamic client registration endpoint
  in the metadata and no public sign-up for API credentials, so a client_id must be issued
  out of band by Acrisure.
- >-
  No OpenID Connect discovery document is served
  (/.well-known/openid-configuration returns 404 on api.acrisure.com), so this is OAuth 2.0
  authorization-server metadata only, not OIDC.
- >-
  No documentation page for authentication exists on any Acrisure host — this profile is
  built entirely from machine-readable discovery metadata, not from prose docs.
