# Tools Overview

> Available tools in the Bizzy MCP Server

The Bizzy MCP server provides tools for managing your business communications
and contacts. Tools are organized by resource type and require appropriate
[permissions](/mcp-server/authentication) to access.

## Available Tool Categories

The MCP server exposes 116 tools across 11 resource categories. Each category
has a dedicated reference page listing every tool, its parameters, permission,
and return shape.

| Category                                             | Tools | Description                                                           |
| ---------------------------------------------------- | ----- | --------------------------------------------------------------------- |
| [Automations](/mcp-server/tools/automations)         | 7     | Create, update, and inspect automations and their executions          |
| [Businesses](/mcp-server/tools/businesses)           | 20    | Business profile, offerings, and online/physical presences            |
| [Contacts](/mcp-server/tools/contacts)               | 20    | Contacts and their emails, phones, and addresses                      |
| [Customers](/mcp-server/tools/customers)             | 10    | Customer records and customer transactions                            |
| [Domains](/mcp-server/tools/domains)                 | 24    | Domains, DNS records, search, registration, verification, and renewal |
| [Email Addresses](/mcp-server/tools/email-addresses) | 2     | List and read connected email addresses                               |
| [Email Templates](/mcp-server/tools/email-templates) | 7     | Manage templates, render previews, and send templated email           |
| [Files](/mcp-server/tools/files)                     | 8     | Upload, download, search, and delete files; manage folders            |
| [Messages](/mcp-server/tools/messages)               | 6     | Read messages, threads, and attachments; update status                |
| [Phone Numbers](/mcp-server/tools/phone-numbers)     | 2     | List and read connected phone numbers (only when phone is enabled)    |
| [Tasks](/mcp-server/tools/tasks)                     | 10    | Task CRUD, search, and assignee management                            |

<Note>
  Phone numbers are not yet generally available, so the 2 tools in that
  category are advertised only to organizations with phone enabled. Every
  other category is always available. The contact phone-number tools under
  [Contacts](/mcp-server/tools/contacts) are unaffected.
</Note>

## Permission Model

Each tool requires specific permissions to execute. Permissions follow the
pattern `resource:action` (e.g., `contacts:read`) or
`resource.subresource:action` for nested resources (e.g.,
`contacts.emails:write`).

**Permission levels:**

| Action   | Description                 |
| -------- | --------------------------- |
| `read`   | View and list resources     |
| `write`  | Create and update resources |
| `delete` | Remove resources            |

**Examples:**

* `contacts:read` - List and view contacts
* `contacts:write` - Create and update contacts
* `contacts.emails:write` - Add or update contact email addresses
* `messages:read` - View and search messages

<Note>
  You grant these permissions on the MCP server's consent screen during the
  OAuth handshake. The set of tools advertised over `tools/list` is filtered
  against the categories you approve. See
  [Authentication](/mcp-server/authentication) for the full flow.
