AI assistants
inboxmcp implements the Model Context Protocol with OAuth 2.1 and Dynamic Client Registration (RFC 7591). Any MCP-compatible AI assistant connects by pasting the MCP URL from the portal — client registration usually happens automatically.

Other MCP clients
Any MCP-compatible client can use inboxmcp — paste the MCP URL from Portal → Integrations and the client handles sign-in itself. For clients without Dynamic Client Registration support, you can provision a Client ID and Client Secret in the portal.
