Every page also links its own mirror with ``, and serves markdown directly to a request sending `Accept: text/markdown`. HTML remains the default ## Authentication (for customer agents) Browsing mihu.ai requires no authentication. To use the Mihu API or MCP server, authentication is **per tenant**; each customer has a tenant at `.mihu.ai`: - [auth.md](https://mihu.ai/auth.md): agent registration and authentication guide; read this first - [OAuth discovery (RFC 8414)](https://mcp.mihu.ai/.well-known/oauth-authorization-server): authorization server metadata for mcp.mihu.ai - [Protected resource metadata (RFC 9728)](https://mihu.ai/.well-known/oauth-protected-resource) - Token endpoint: `https://mcp.mihu.ai/oauth/token`; grants: `client_credentials`, `authorization_code` (PKCE) - `client_id` = your tenant subdomain (e.g. `minders`); `client_secret` = a Mihu API token created in your tenant panel at `https://.mihu.ai` - Tokens are bound to one tenant, inherit that API key's panel permissions, and expire after 1 hour - Direct-header alternative (no OAuth): send `Authorization: Bearer ` and `X-Mihu-Tenant: ` - Not a customer yet?

No coding required; the API, MCP server, and n8n node drive the same platform programmatically. Mihu runs its own speech stack (STT → NLU → TTS in real time), and publishes some of those models openly on Hugging Face. - [Platform overview](https://mihu.ai/platform): the Mihu AI contact center platform, including the Agent Builder - [Voice agent](https://mihu.ai/voice-agent): AI agents for inbound and outbound phone calls - [WhatsApp](https://mihu.ai/whatsapp): WhatsApp Business automation and calling - [Messaging agent](https://mihu.ai/messaging-agent): Instagram, Messenger, and web chat automation - [CRM agent](https://mihu.ai/crm-agent): CRM-integrated AI workflows - [Quality coaching](https://mihu.ai/quality-coaching): AI-driven QA and agent coaching - [VoIP infrastructure](https://mihu.ai/voip-infrastructure): SIP trunking, PBX integration, phone numbers - [On-premise deployment](https://mihu.ai/on-premise): full agent stack (STT/TTS on CPU, self-hosted LLM, SIP, actions, data) inside customer infrastructure - [Integrations](https://mihu.ai/integrations): Zapier, n8n, CRMs, calendars, and more - [Assistants](https://mihu.ai/assistants): Mihu Assistant (run the platform by asking), Builder Assistant (build and deploy what the platform does not ship), Simulator Studio, Improvement Agent ## Resources - [Blog](https://mihu.ai/blog): guides on voice AI, WhatsApp API, IVR replacement, and integrations - [Case studies](https://mihu.ai/case-studies) - [Help center](https://mihu.ai/help-center) - [API reference](https://mihu.ai/api-reference) - [Documentation](https://mihu.ai/documentation) ## Company - [About](https://mihu.ai/about) - [Contact](https://mihu.ai/contact) - [Security](https://mihu.ai/security) - [Privacy](https://mihu.ai/privacy) ## Optional - [Audio demos](https://mihu.ai/audio-demo): sample AI voice agent calls in multiple languages and industries - [Solutions by industry](https://mihu.ai/solutions): healthcare, automotive, e-commerce, real estate, financial services - [Careers](https://mihu.ai/careers) - [Partners](https://mihu.ai/partners)
