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 Engage account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Engage with - [OpenAI Agents SDK](https://composio.dev/toolkits/engage/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/engage/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/engage/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/engage/framework/claude-cowork) - [Grok Bot](https://composio.dev/toolkits/engage/framework/grok-bot) - [Codex](https://composio.dev/toolkits/engage/framework/codex) - [OpenClaw](https://composio.dev/toolkits/engage/framework/openclaw) - [Hermes](https://composio.dev/toolkits/engage/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/engage/framework/google-adk) - [LangChain](https://composio.dev/toolkits/engage/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/engage/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/engage/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/engage/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/engage/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/engage/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/engage/framework/autogen) ## TL;DR ### How Atomic Agent connects to Engage 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 Engage to Atomic Agent ### Connect Engage 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 Engage. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Engage 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 Engage MCP server, and what's possible with it? The Engage MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Engage account. It provides structured and secure access so your agent can perform Engage operations on your behalf. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `ENGAGE_ADD_CUSTOMER_TO_ACCOUNTS` | Add Customer to Accounts | Tool to add a customer to one or more account entities. Use when you need to associate a user with accounts and optionally assign roles. | | `ENGAGE_ADD_USER_TO_LISTS` | Add User to Lists | Tool to add a Customer or Account to one or more Lists in Engage.so.

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 Engage from Atomic Agent With your account connected, ask Atomic Agent to work with Engage in natural language. You can connect more apps through the same Composio integration as you need them.

With a standalone Engage MCP server, the agents and LLMs can only access a fixed set of Engage tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Engage 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 Engage tools. ### Can I manage the permissions and scopes for Engage while using Tool Router? Yes, absolutely. You can configure which Engage 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 Engage data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
