If you'd rather read the explained summary instead of this plain list, start with
**[Key concepts](/en/guides/conceptos/)**.

**Access to everything** — an agent switch that grants access to every resource in your account
(documents, templates, MCP servers) without needing tags. See **[AI agents](/en/guides/agentes-ia/)**.

**Account (tenant)** — your agency or business inside Nuntius, an isolated compartment. See
**[Key concepts](/en/guides/conceptos/)**.

**AI agent** — the configurable identity that handles your conversations: instructions, model and
assigned resources. See **[Key concepts](/en/guides/conceptos/)**.

**API key** — a secret credential for calling `/public/v1` from your own code. See
**[API keys and access media](/en/guides/claves-api/)**.

**Appointment** — a scheduled event in the Calendar, created by hand or by the AI, with a slot computed
by the availability engine. See **[Calendar and appointments](/en/guides/agenda/)**.

**Audience** — `Internal` or `Both`; decides whether an anonymous visitor on a public channel can reach an
action, template or document. See **[Agent control: resources and permissions](/en/guides/control-del-agente/)**.

**BYO-MCP** — an external MCP server you register yourself in Settings to give your agent access to a
system of your own with no native connector; under your own responsibility. See
**[Integrations](/en/integrations/)**.

**Campaign** — sending an approved WhatsApp template to a list or a selection of contacts. See
**[Contacts and marketing](/en/guides/contactos-marketing/)**.

**Channel** — the type of path your agent talks through (WhatsApp, Telegram, Web widget, Messenger /
Instagram Direct). See **[Channels](/en/guides/canales/)**.

**Confirmation (MCP)** — the `confirm: true` argument every write tool of the MCP server requires before
touching the API. See **[Confirmation on writes](/en/mcp/confirm/)**.

**Connector** — a first-party integration resolved live (HubSpot, for example): a token or credential,
a real verification, and actions enabled one at a time. See **[Integrations](/en/integrations/)**.

**Contact** — the customer's own record (phone, verification, marketing lists), shared across all their
leads and conversations. See **[Contacts and marketing](/en/guides/contactos-marketing/)**.

**Conversation** — the message thread with a customer on a channel instance; AI, HUMAN or QUEUED modes.
See **[Conversations](/en/guides/conversaciones/)**.

**Editor** (role) — a role with day-to-day operation (conversations, leads, appointments…) with no access
to billing. See **[Team and roles](/en/guides/equipo-roles/)**.

**Escalation** — when the AI stops answering and hands the conversation to someone on your team, either
because the customer asks or a rule fires. See **[Conversations](/en/guides/conversaciones/)**.

**Flow** — a multi-step process, with optional branching, that your digital team runs on its own. See
**[Jobs and flows](/en/guides/trabajos-flujos/)**.

**Funnel** — the sequence of stages a lead moves through, with its kanban board. See
**[Leads](/en/guides/leads/)**.

**Hand-off** (between agents) — passing a conversation from one agent to another, with configured rules
and destinations. See **[Hand-off between agents](/en/guides/derivacion-agentes/)**.

**Instance** — one concrete connection of a channel (a WhatsApp number, a widget); several instances of
the same type can coexist. See **[Channels](/en/guides/canales/)**.

**Instruction ("consigna")** — a flow you ask your assistant to build over chat, in your own words; it's
generated and edited exactly like one built by hand. See **[Jobs and flows](/en/guides/trabajos-flujos/)**.

**Job** — a standalone task your assistant runs, once or repeated, with its own step-by-step history. See
**[Jobs and flows](/en/guides/trabajos-flujos/)**.

**Lead** — an opportunity in your sales funnel, captured automatically by the AI or entered by hand. See
**[Leads](/en/guides/leads/)**.

**MCP (Model Context Protocol)** — the open standard used both by Nuntius's own MCP server and by
any external MCP server (BYO-MCP). See **[MCP](/en/mcp/getting-started/)**.

**MCP server** — a server that exposes tools over the MCP protocol; either Nuntius's own (exposes
your account to your external AI) or an external one you register (BYO-MCP, plugs third-party tools into
your agent). See **[MCP](/en/mcp/getting-started/)**.

**Memory (customer)** — the automatic summary the agent keeps per contact, shared across channels; visible,
editable and deletable from their record, with configurable retention in Settings. See **[Marketing and
contacts](/en/guides/contactos-marketing/)**.

**Mode: AI / HUMAN / QUEUED** — the three states a conversation can be in, depending on who is answering
right now. See **[Conversations](/en/guides/conversaciones/)**.

**On-screen assistant (Copilot)** — the assistant that navigates, highlights and, with your explicit
confirmation, fills in and clicks real buttons on your own website or Platform. See
**[Support and on-screen assistant](/en/guides/soporte-asistente/)**.

**Permission** — the fine-grained catalog that decides what an identified caller (person, channel
employee, API key) can do, per area of the account. See **[Agent control: resources and permissions](/en/guides/control-del-agente/)**.

**Plan** — your account's subscription tier (Starter, Pro, Enterprise), which decides what's available
(the public API and MCP, for example, only on Pro and Enterprise). See **[Billing and plans](/en/guides/facturacion/)**.

**Quality (lead)** — an interest rating: Hot, Warm, Cold or Unrated. See **[Leads](/en/guides/leads/)**.

**Resource** — anything an agent can use: a document, a template, or an MCP server. See
**[Key concepts](/en/guides/conceptos/)**.

**Responsible person** — the person (or whole team, if none is assigned) who's notified when a
conversation on a given channel escalates. See **[Channels](/en/guides/canales/)**.

**Role** — Admin, Editor or Viewer; decides which screens and actions each person on your team can reach.
See **[Team and roles](/en/guides/equipo-roles/)**.

**Scope** — the specific permission (read or manage, per resource) sealed into an API key. See
**[Authentication](/en/api/authentication/)**.

**Tag** — a word or phrase that groups resources (documents, templates, MCP servers) to decide which
agent can see them. See **[Key concepts](/en/guides/conceptos/)**.

**Task** — see **Job**.

**Template** — a WhatsApp message pre-approved by Meta for messaging outside an ongoing conversation, or
a reusable knowledge-base document. See **[Contacts and marketing](/en/guides/contactos-marketing/)** and
**[Knowledge and documents](/en/guides/conocimiento-documentos/)**.

**Tenant** — see **Account**.

**Ticket** (internal) — an internal case your team runs about a contact, linked to their lead or
conversation when relevant. Different from a Support ticket (to ask your provider for help). See
**[Tickets](/en/guides/tickets/)**.

**Viewer** (role) — a role that can see most screens but change nothing. See **[Team and roles](/en/guides/equipo-roles/)**.

**Web widget** — the chat embedded on your own website; each instance has its own snippet and language.
See **[Web widget](/en/guides/widget-web/)**.
