## Introduction

This guide walks you through connecting Callingly to the Claude Agent SDK using the Composio tool router. By the end, you'll have a working Callingly agent that can activate a client account for onboarding, create an outbound call to new lead, get agent schedule for next week through natural language commands.
This guide will help you understand how to give your Claude Agent SDK agent real control over a Callingly account through Composio's Callingly MCP server.
Before we dive in, let's take a quick look at the key ideas and tools involved.

## What is Claude Agent SDK?

The Claude Agent SDK is Anthropic's official framework for building AI agents powered by Claude. It provides a streamlined interface for creating agents with MCP tool support and conversation management.
Key features include:
- Native MCP Support: Built-in support for Model Context Protocol servers
- Permission Modes: Control tool execution permissions
- Streaming Responses: Real-time response streaming for interactive applications
- Context Manager: Clean async context management for sessions

## What is the Callingly MCP server, and what's possible with it?

The Callingly MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Callingly account. It provides structured and secure access to your Callingly environment, so your agent can automate lead follow-ups, manage agents and clients, trigger outbound calls, and keep your sales workflows moving without manual intervention.
- Automated outbound call creation: Instantly generate outbound call records so your team can respond to new leads within seconds without lifting a finger.
- Agent and team management: Let your agent create, delete, or update agents and teams as your sales organization changes and grows.
- Client onboarding and offboarding: Seamlessly add, activate, deactivate, or remove client accounts as your business requires—no more manual data entry.
- Real-time webhook setup: Set up and delete webhooks to receive instant notifications for specific call or lead events, keeping your CRM and other tools in sync.
- Availability and scheduling insights: Retrieve agent schedules to optimize call assignments and guarantee leads get connected when agents are actually available.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CALLINGLY_ACTIVATE_DEACTIVATE_CLIENT` | Activate/Deactivate Client Account | Tool to activate or deactivate a client account. Use when you need to toggle client access after onboarding or offboarding. Example: "Activate client 123" or "Deactivate client 456". |
| `CALLINGLY_CREATE_AGENT` | Create Agent | Tool to create a new agent. Use when you need to register an agent in Callingly after gathering their account ID and contact details. |
| `CALLINGLY_CREATE_CALL` | Create Outbound Call | Creates a new outbound call record and initiates a real outbound call, which incurs cost — ensure explicit user authorization and compliance with applicable consent and telemarketing regulations before use. The call will be routed to available agents on the specified team based on account-level routing configuration. Use List Teams first to get valid account_id and team_id values. Returns a call_id that can be used with Get Call to retrieve call status, recordings, and other details. |
| `CALLINGLY_CREATE_CLIENT` | Create Client | Creates a new client account in Callingly. Clients are sub-accounts under your agency account that can have their own teams, agents, and billing. Use this when onboarding a new business customer to your Callingly agency. |
| `CALLINGLY_CREATE_TEAM` | Create Team | Tool to create a new team. Use when setting up a team configuration before adding agents. |
| `CALLINGLY_CREATE_WEBHOOK` | Create Webhook | Tool to create a new webhook for call or lead events. Use when you need to receive real-time notifications on specific events. Example: "Create a webhook for call_completed events to http://example.com/callback". |
| `CALLINGLY_DELETE_AGENT` | Delete Agent | Permanently delete an agent from a Callingly account. Use when removing an agent who should no longer receive calls. Requires both the agent ID and the account ID the agent belongs to. |
| `CALLINGLY_DELETE_CLIENT` | Delete Client | Tool to delete a client. Use when you need to remove an existing client from your account after confirming its ID. |
| `CALLINGLY_DELETE_LEAD` | Delete Lead | Tool to delete a lead by ID. Use when you need to permanently remove a lead from your account after confirming its ID. Returns a success confirmation. |
| `CALLINGLY_DELETE_WEBHOOK` | Delete Webhook | Tool to delete a webhook. Use when permanently removing a webhook by its ID. |
| `CALLINGLY_GET_AGENT_SCHEDULE` | Get Agent Schedule | Tool to retrieve the availability schedule for a specific agent. Use when you need to know which days and times the agent is available. |
| `CALLINGLY_GET_CALL` | Get Call | Retrieves detailed information about a specific call by its unique ID. Returns comprehensive call metadata including status, duration, lead information, agent details, recording URLs, transcripts, and AI-generated insights. Use the LIST_CALLS action first to obtain valid call IDs. |
| `CALLINGLY_GET_LEAD` | Get Lead | Tool to retrieve details of a specific lead by its ID. Use when you need full lead details before follow-up actions. |
| `CALLINGLY_GET_TEAM` | Get Team | Tool to retrieve details of a specific team. Use after obtaining the team ID to fetch its configuration details. |
| `CALLINGLY_GET_WEBHOOK` | Get Webhook | Tool to retrieve details of a specific webhook by its ID. Use when you need to inspect a webhook's configuration before modifying or deleting it. |
| `CALLINGLY_LIST_CALLS` | List Calls | Tool to list calls. Use when you need to retrieve multiple call records with optional filters such as date range, team, and pagination after identifying the need for a collection of calls. |
| `CALLINGLY_LIST_CLIENTS` | List Clients | Tool to list clients. Use when you need to retrieve all clients associated with your account. |
| `CALLINGLY_LIST_LEADS` | List Leads | Tool to list leads based on provided filters like date range or phone number. Use after confirming filter criteria when bulk lead retrieval is needed. |
| `CALLINGLY_LIST_TEAMS` | List Teams | Tool to list teams. Use when you need to retrieve all teams associated with your account. |
| `CALLINGLY_LIST_TEAM_USERS` | List Team Users | Retrieve all agents assigned to a specific team in Callingly. Returns each agent's ID, name, priority, call cap, and any custom/integration identifiers. Use this to audit team composition or before performing agent management operations like updates or removals. |
| `CALLINGLY_LIST_USERS` | List Users | Tool to retrieve a list of agents. Use when you need to see all agents available under the authenticated account, optionally filtering by a specific client account. |
| `CALLINGLY_LIST_WEBHOOKS` | List Webhooks | Tool to list configured webhooks. Use when you need to retrieve all webhooks configured in your account to review or manage them. |
| `CALLINGLY_REMOVE_TEAM_AGENT` | Remove Team Agent | Tool to remove a specific agent from a team. Use when you need to disassociate an agent from a team after confirming both team and agent IDs. |
| `CALLINGLY_UPDATE_AGENT` | Update Agent | Tool to update an existing agent's details. Use when you need to modify agent information post-creation. |
| `CALLINGLY_UPDATE_LEAD` | Update Lead | Tool to update an existing lead's information. Use when you need to modify lead contact details, status, or blocking settings. |

## Creating MCP Server - Stand-alone vs Composio SDK

The Callingly MCP server is an implementation of the Model Context Protocol that connects your AI agent to Callingly. It provides structured and secure access so your agent can perform Callingly operations on your behalf through a secure, permission-based interface.
With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster.

## Step-by-step Guide

- Composio API Key and Claude/Anthropic API Key
- Primary know-how of Claude Agents SDK
- A Callingly account
- Some knowledge of Python

### 1. Getting API Keys for Claude/Anthropic and Composio

Claude/Anthropic API Key
- Go to the [Anthropic Console](https://console.anthropic.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models.
- Keep the API key safe.
Composio API Key
- Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs).
- Navigate to your API settings and generate a new API key.
- Store this key securely as you'll need it for authentication.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Callingly MCP?

With a standalone Callingly MCP server, the agents and LLMs can only access a fixed set of Callingly tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Callingly and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Claude Agent SDK?

Yes, you can. Claude Agent SDK fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Callingly tools.

### Can I manage the permissions and scopes for Callingly while using Tool Router?

Yes, absolutely. You can configure which Callingly scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Callingly data and credentials are handled as safely as possible.
