This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Callingly account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Callingly with - [OpenAI Agents SDK](https://composio.dev/toolkits/callingly/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/callingly/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/callingly/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/callingly/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/callingly/framework/codex) - [OpenClaw](https://composio.dev/toolkits/callingly/framework/openclaw) - [Hermes](https://composio.dev/toolkits/callingly/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/callingly/framework/google-adk) - [LangChain](https://composio.dev/toolkits/callingly/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/callingly/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/callingly/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/callingly/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/callingly/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/callingly/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/callingly/framework/autogen) ## TL;DR ### How Atomic Agent connects to Callingly Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication. Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account. ## Connect Callingly to Atomic Agent ### Connect Callingly to Atomic Agent - Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key. - In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart. - Ask Atomic Agent to do something in Callingly. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Callingly account, then return to Atomic Agent to continue. ### Headless setup Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file. ```bash COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY ``` ## 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.

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 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.

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.

Supports partial updates - only provide fields you want to change. Note: When updating event-specific fields (call_status, call_lead_status, field, filter), you must also include the event field in your request. | ## Supported Triggers None listed. ## Troubleshooting ### Why is my API key rejected? Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying. ### Why are Composio tools unavailable after saving a key? Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk. ### Does Composio have a free plan? The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection. ## Complete Code None listed. ## Conclusion ### Use Callingly from Atomic Agent With your account connected, ask Atomic Agent to work with Callingly in natural language. You can connect more apps through the same Composio integration as you need them.

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 Atomic Agent? Yes, you can. Atomic Agent 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. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
