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 Dropcontact account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Dropcontact with - [ChatGPT](https://composio.dev/toolkits/dropcontact/framework/chatgpt) - [Antigravity](https://composio.dev/toolkits/dropcontact/framework/antigravity) - [OpenAI Agents SDK](https://composio.dev/toolkits/dropcontact/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/dropcontact/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/dropcontact/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/dropcontact/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/dropcontact/framework/codex) - [OpenClaw](https://composio.dev/toolkits/dropcontact/framework/openclaw) - [Hermes](https://composio.dev/toolkits/dropcontact/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/dropcontact/framework/google-adk) - [LangChain](https://composio.dev/toolkits/dropcontact/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/dropcontact/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/dropcontact/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/dropcontact/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/dropcontact/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/dropcontact/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/dropcontact/framework/autogen) ## TL;DR ### How Atomic Agent connects to Dropcontact 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 Dropcontact to Atomic Agent ### Connect Dropcontact 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 Dropcontact. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Dropcontact 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 Dropcontact MCP server, and what's possible with it? The Dropcontact MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Dropcontact account. It provides structured and secure access to contact enrichment and B2B email finding, so your agent can perform actions like verifying professional email addresses, enriching contact lists, tracking enrichment status, and managing webhook subscriptions on your behalf. - Batch contact enrichment: Instantly enrich up to 250 contacts at once with validated email addresses and company details, letting your agent automate lead research and CRM updates. - Email verification and validation: Ensure the emails in your contact lists are professional and verified, reducing bounce rates and improving outreach quality. - Retrieve enrichment results: Have your agent fetch completed enrichment data for submitted requests, so you can quickly access up-to-date contact intelligence. - Manage webhook subscriptions: List and inspect your webhook subscriptions, making it easy to keep track of automated updates and integrations with your workflow. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `DROPCONTACT_CREATE_WEBHOOK_SUBSCRIPTION` | Create Webhook Subscription | Tool to create a new webhook subscription for receiving automatic notifications when enrichment results are ready. Use this instead of polling GET /v1/enrich/all to receive push notifications when contact enrichment processing completes. Currently only supports 'enrich_api_result' event type. | | `DROPCONTACT_DELETE_WEBHOOK_SUBSCRIPTION` | Delete Webhook Subscription | Tool to delete a webhook subscription. Use when you need to remove a configured webhook and stop receiving notifications. Alternatively, you can pause a subscription by setting it to inactive using the update endpoint. | | `DROPCONTACT_ENRICH_CONTACTS` | Initiate Contact Enrichment | Initiates asynchronous batch enrichment for up to 250 contacts with email finding, validation, and company information. Returns a request_id that must be used with the 'Retrieve Enrichment Results' action to fetch the enriched data. Each contact needs at least one of: email, OR (first_name + last_name + company), OR (full_name + company), OR LinkedIn URL. The enrichment typically completes within 30-60 seconds depending on batch size. | | `DROPCONTACT_LIST_WEBHOOK_SUBSCRIPTIONS` | List Webhook Subscriptions | Tool to list webhook subscriptions. Use when you need to inspect your configured webhooks. | | `DROPCONTACT_LIST_WEBHOOK_SUBSCRIPTIONS_V2` | List Webhook Subscriptions V2 | Tool to list all webhook subscriptions configured for the account. Returns webhook URLs, event types, and subscription details. Use when you need to inspect your configured webhooks. | | `DROPCONTACT_RETRIEVE_ENRICHMENT_RESULTS` | Retrieve Enrichment Results | Retrieves enriched contact data by request ID after submitting contacts for enrichment. Use this tool to fetch the results of a contact enrichment request created with the 'Batch Enrich Contacts' action. The enrichment process may take 30-60 seconds. If the request is still processing, the response will indicate 'success=false' with a reason message. Once complete, you'll receive enriched data including emails with qualification status, LinkedIn profiles, company information, phone numbers, and location details. Note: You can retrieve partial results even if all contacts haven't been processed yet. | | `DROPCONTACT_UPDATE_WEBHOOK_SUBSCRIPTION` | Update Webhook Subscription | Tool to update an existing webhook subscription. Use when you need to modify the callback URL, rate limiting settings, or active status. The event_type field cannot be changed after creation. | ## 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 Dropcontact from Atomic Agent With your account connected, ask Atomic Agent to work with Dropcontact in natural language. You can connect more apps through the same Composio integration as you need them.

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