## Introduction

This guide walks you through connecting Callingly to the OpenAI Agents 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 OpenAI Agents 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 OpenAI Agents SDK?

The OpenAI Agents SDK is a lightweight framework for building AI agents that can use tools and maintain conversation state. It provides a simple interface for creating agents with hosted MCP tool support.
Key features include:
- Hosted MCP Tools: Connect to external services through hosted MCP endpoints
- SQLite Sessions: Persist conversation history across interactions
- Simple API: Clean interface with Agent, Runner, and tool configuration
- Streaming Support: Real-time response streaming for interactive applications

## 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_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. |

## 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

### 1. Prerequisites

Before starting, make sure you have:
- Composio API Key and OpenAI API Key
- Primary know-how of OpenAI Agents SDK
- A live Callingly project
- Some knowledge of Python or Typescript

### 1. Getting API Keys for OpenAI and Composio

OpenAI API Key
- Go to the [OpenAI dashboard](https://platform.openai.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models, or you can connect to another model provider.
- 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).
- Go to Settings and copy your API key.

### 2. Install dependencies

Install the Composio SDK and the OpenAI Agents SDK.
```python
pip install composio_openai_agents openai-agents python-dotenv
```

```typescript
npm install @composio/openai-agents @openai/agents dotenv
```

### 3. Set up environment variables

Create a .env file and add your OpenAI and Composio API keys.
```bash
OPENAI_API_KEY=sk-...your-api-key
COMPOSIO_API_KEY=your-api-key
USER_ID=composio_user@gmail.com
```

### 4. Import dependencies

What's happening:
- You're importing all necessary libraries.
- The Composio and OpenAIAgentsProvider classes are imported to connect your OpenAI agent to Composio tools like Callingly.
```python
import asyncio
import os
from dotenv import load_dotenv

from composio import Composio
from composio_openai_agents import OpenAIAgentsProvider
from agents import Agent, Runner, HostedMCPTool, SQLiteSession
```

```typescript
import 'dotenv/config';
import { Composio } from '@composio/core';
import { OpenAIAgentsProvider } from '@composio/openai-agents';
import { Agent, hostedMcpTool, run, OpenAIConversationsSession } from '@openai/agents';
import * as readline from 'readline';
```

### 5. Set up the Composio instance

No description provided.
```python
load_dotenv()

api_key = os.getenv("COMPOSIO_API_KEY")
user_id = os.getenv("USER_ID")

if not api_key:
    raise RuntimeError("COMPOSIO_API_KEY is not set. Create a .env file with COMPOSIO_API_KEY=your_key")

# Initialize Composio
composio = Composio(api_key=api_key, provider=OpenAIAgentsProvider())
```

```typescript
dotenv.config();

const composioApiKey = process.env.COMPOSIO_API_KEY;
const userId = process.env.USER_ID;

if (!composioApiKey) {
  throw new Error('COMPOSIO_API_KEY is not set. Create a .env file with COMPOSIO_API_KEY=your_key');
}
if (!userId) {
  throw new Error('USER_ID is not set');
}

// Initialize Composio
const composio = new Composio({
  apiKey: composioApiKey,
  provider: new OpenAIAgentsProvider(),
});
```

### 6. Create a Tool Router session

What is happening:
- You give the Tool Router the user id and the toolkits you want available. Here, it is only callingly.
- The router checks the user's Callingly connection and prepares the MCP endpoint.
- The returned session.mcp.url is the MCP URL that your agent will use to access Callingly.
- This approach keeps things lightweight and lets the agent request Callingly tools only when needed during the conversation.
```python
# Create a Callingly Tool Router session
session = composio.create(
    user_id=user_id,
    toolkits=["callingly"]
)

mcp_url = session.mcp.url
```

```typescript
// Create Tool Router session for Callingly
const session = await composio.create(userId as string, {
  toolkits: ['callingly'],
});
const mcpUrl = session.mcp.url;
```

### 7. Configure the agent

No description provided.
```python
# Configure agent with MCP tool
agent = Agent(
    name="Assistant",
    model="gpt-5",
    instructions=(
        "You are a helpful assistant that can access Callingly. "
        "Help users perform Callingly operations through natural language."
    ),
    tools=[
        HostedMCPTool(
            tool_config={
                "type": "mcp",
                "server_label": "tool_router",
                "server_url": mcp_url,
                "headers": {"x-api-key": api_key},
                "require_approval": "never",
            }
        )
    ],
)
```

```typescript
// Configure agent with MCP tool
const agent = new Agent({
  name: 'Assistant',
  model: 'gpt-5',
  instructions:
    'You are a helpful assistant that can access Callingly. Help users perform Callingly operations through natural language.',
  tools: [
    hostedMcpTool({
      serverLabel: 'tool_router',
      serverUrl: mcpUrl,
      headers: { 'x-api-key': composioApiKey },
      requireApproval: 'never',
    }),
  ],
});
```

### 8. Start chat loop and handle conversation

No description provided.
```python
print("\nComposio Tool Router session created.")

chat_session = SQLiteSession("conversation_openai_toolrouter")

print("\nChat started. Type your requests below.")
print("Commands: 'exit', 'quit', or 'q' to end\n")

async def main():
    try:
        result = await Runner.run(
            agent,
            "What can you help me with?",
            session=chat_session
        )
        print(f"Assistant: {result.final_output}\n")
    except Exception as e:
        print(f"Error: {e}\n")

    while True:
        user_input = input("You: ").strip()
        if user_input.lower() in {"exit", "quit", "q"}:
            print("Goodbye!")
            break

        result = await Runner.run(
            agent,
            user_input,
            session=chat_session
        )
        print(f"Assistant: {result.final_output}\n")

asyncio.run(main())
```

```typescript
// Keep conversation state across turns
const conversationSession = new OpenAIConversationsSession();

// Simple CLI
const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout,
  prompt: 'You: ',
});

console.log('\nComposio Tool Router session created.');
console.log('\nChat started. Type your requests below.');
console.log("Commands: 'exit', 'quit', or 'q' to end\n");

try {
  const first = await run(agent, 'What can you help me with?', { session: conversationSession });
  console.log(`Assistant: ${first.finalOutput}\n`);
} catch (e) {
  console.error('Error:', e instanceof Error ? e.message : e, '\n');
}

rl.prompt();

rl.on('line', async (userInput) => {

  if (['exit', 'quit', 'q'].includes(text.toLowerCase())) {
    console.log('Goodbye!');
    rl.close();
    process.exit(0);
  }

  if (!text) {
    rl.prompt();
    return;
  }

  try {
    const result = await run(agent, text, { session: conversationSession });
    console.log(`\nAssistant: ${result.finalOutput}\n`);
  } catch (e) {
    console.error('Error:', e instanceof Error ? e.message : e, '\n');
  }

## Conclusion

This was a starter code for integrating Callingly MCP with OpenAI Agents SDK to build a functional AI agent that can interact with Callingly.
Key features:
- Hosted MCP tool integration through Composio's Tool Router
- SQLite session persistence for conversation history
- Simple async chat loop for interactive testing
You can extend this by adding more toolkits, implementing custom business logic, or building a web interface around the agent.

## 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 OpenAI Agents SDK?

Yes, you can. OpenAI Agents 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.
