VolunteerReminder authentication

VolunteerReminder lets an AI assistant start a free trial, import a volunteer roster, and preview upcoming shifts. New accounts start in test mode — nothing texts a real volunteer until a human turns live sends on from the dashboard.

Machine-readable metadata: /auth.md. This page is the HTML twin.

• Host-level (matches a scan of this origin): /.well-known/oauth-protected-resource
• REST v1: /.well-known/oauth-protected-resource/api/v1
• MCP: https://mcp.volunteerreminder.com/.well-known/oauth-protected-resource/mcp
• Authorization server: /.well-known/oauth-authorization-server

VolunteerReminder is the authorization server. There is no separate AS host.

1. Add the connector URL https://mcp.volunteerreminder.com (Streamable HTTP endpoint: https://mcp.volunteerreminder.com/mcp).
2. The client reads RFC 9728, then RFC 8414, and registers at https://volunteerreminder.com/oauth/register.
3. The coordinator signs in at https://volunteerreminder.com/oauth/authorize, then clicks Allow.
4. The client exchanges the code at https://volunteerreminder.com/oauth/token for a vra_ access token.

No vrk_ paste on this path.

1. Start a trial at /signup or with the create_account MCP tool. That tool does not return a key.
2. Mint a key at Account → Security.
3. Send Authorization: Bearer vrk_… on MCP and REST v1 calls.

• WorkOS agent-auth identity registration, ID-JAG, or claim ceremonies
• A second authorization server
• Live SMS from an agent. Import stays in test mode. A human turns live sends on from the dashboard.
