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 Campayn account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Campayn with - [OpenAI Agents SDK](https://composio.dev/toolkits/campayn/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/campayn/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/campayn/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/campayn/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/campayn/framework/codex) - [OpenClaw](https://composio.dev/toolkits/campayn/framework/openclaw) - [Hermes](https://composio.dev/toolkits/campayn/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/campayn/framework/google-adk) - [LangChain](https://composio.dev/toolkits/campayn/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/campayn/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/campayn/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/campayn/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/campayn/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/campayn/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/campayn/framework/autogen) ## TL;DR ### How Atomic Agent connects to Campayn 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 Campayn to Atomic Agent ### Connect Campayn 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 Campayn. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Campayn 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 Campayn MCP server, and what's possible with it? The Campayn MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Campayn account. It provides structured and secure access to your contact lists, email campaigns, and subscriber management, so your agent can handle tasks like creating contacts, managing lists, fetching messages, and maintaining your email marketing automation—all on your behalf. - Effortless contact management: Easily add new contacts, update existing ones, or permanently delete subscribers from your Campayn lists through your agent. - Automated list organization: Ask your agent to create, retrieve, or clean up contact lists, making it simple to segment and manage your audience. - Campaign and message insights: Have your agent fetch the details of individual messages or retrieve all campaign messages to keep you up to date with your email marketing efforts. - Streamlined webform management: Direct your agent to delete outdated or unnecessary webforms, keeping your lead capture workflow tidy and current. - Bulk data retrieval: Let your agent pull all contacts in a specific list or fetch all available lists with a single command, saving you time and effort when working with large datasets. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `CAMPAYN_CREATE_CONTACT` | Create Contact | Tool to create a new contact in a specific list. Use when you need to add a contact after gathering details. | | `CAMPAYN_DELETE_CONTACT` | Delete Contact | Tool to delete a specific contact. Use when you need to remove a contact permanently after confirming it should be deleted. Example: "Delete contact 123". | | `CAMPAYN_DELETE_LIST` | Delete List | Tool to delete a specific contact list. Use when cleaning up unused lists after confirming they are no longer needed. Example: "Delete list 123". | | `CAMPAYN_DELETE_WEBFORM` | Delete webform | Delete a specific webform from a contact list. Use this to permanently remove a webform that is no longer needed. Requires both the list_id and webform_id - use Get Webforms action first to find these values. Note: The API returns success even for non-existent webform IDs (idempotent delete behavior). | | `CAMPAYN_GET_CONTACT` | Get Contact | Tool to retrieve a specific contact by ID. Use when you need to fetch full contact details after confirming the contact ID. | | `CAMPAYN_GET_CONTACTS` | Get Contacts | Retrieves all contacts from a specific contact list in Campayn. Returns contact details including email, name, address, and confirmation status. Use 'Get Lists' action first to obtain the list_id. Supports optional filtering by contact name/email/company. | | `CAMPAYN_GET_LISTS` | Get Lists | Tool to retrieve all contact lists. Use when you need to fetch available lists before performing list-specific actions. Example prompt: "List all my contact lists". | | `CAMPAYN_GET_MESSAGE` | Get Message Statistics | Tool to retrieve engagement statistics for a specific email message by ID. Returns views, positive responses (clicks), and negative responses (unsubscribes/bounces). Use GET_MESSAGES first to get the list of available message IDs. | | `CAMPAYN_GET_MESSAGES` | Get Messages | Tool to retrieve all email messages.

Example prompt: "List all webforms in list 123". | | `CAMPAYN_UNSUBSCRIBE_CONTACT` | Unsubscribe Contact | Tool to unsubscribe contacts from a list by contact id or email address. Use when you need to remove contacts from a mailing list. If id is provided, only that specific contact will be unsubscribed. If email is provided, all contacts on that list with that email will be unsubscribed. | | `CAMPAYN_UPDATE_LIST` | Update List | Tool to update a contact list. Use after confirming list ID and desired changes. Example: Update list 123 name to 'Newsletter Subscribers'. | ## 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 Campayn from Atomic Agent With your account connected, ask Atomic Agent to work with Campayn in natural language. You can connect more apps through the same Composio integration as you need them.

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