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 Tomba account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Tomba with - [OpenAI Agents SDK](https://composio.dev/toolkits/tomba/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/tomba/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/tomba/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/tomba/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/tomba/framework/codex) - [OpenClaw](https://composio.dev/toolkits/tomba/framework/openclaw) - [Hermes](https://composio.dev/toolkits/tomba/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/tomba/framework/google-adk) - [LangChain](https://composio.dev/toolkits/tomba/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/tomba/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/tomba/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/tomba/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/tomba/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/tomba/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/tomba/framework/autogen) ## TL;DR ### How Atomic Agent connects to Tomba 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 Tomba to Atomic Agent ### Connect Tomba 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 Tomba. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Tomba 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 Tomba MCP server, and what's possible with it? The Tomba MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Tomba account. It provides structured and secure access to your B2B email finding, lead management, and account configuration tools, so your agent can perform actions like discovering leads, managing lists, validating domains, and monitoring account usage on your behalf. - Lead discovery and enrichment: Ask your agent to list available lead attributes or add new leads directly into your Tomba account for streamlined outreach. - Lead list management: Effortlessly retrieve, update, or delete lead lists, helping you stay organized and keep your data current. - Domain validation and status checks: Have your agent check if a domain is webmail or disposable to ensure better deliverability and lead quality. - API key and account management: Direct your agent to list, create, or revoke API keys, and review usage statistics to keep your Tomba integration secure and efficient. - Usage monitoring and reporting: Let your agent fetch up-to-date API usage statistics, keeping you informed about your plan limits and consumption. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `TOMBA_ATTRIBUTES_LIST` | List Lead Attributes | Retrieves all custom lead attributes defined in your Tomba account. Use this action to discover the available attributes that can be used when creating or updating leads. Returns attribute metadata including name, identifier, type, and timestamps. No input parameters required. | | `TOMBA_DOMAIN_STATUS` | Domain Status | Tool to check if a domain is webmail or disposable. Use when validating email deliverability constraints. | | `TOMBA_KEYS_DELETE` | Delete API Key by ID | Tool to delete an API key by its numeric ID. Use when you need to permanently revoke an API key before its expiration. Note: You can get the numeric key ID from the TOMBA_KEYS_LIST action. | | `TOMBA_KEYS_LIST` | List API Keys | Tool to list all API keys. Use when you want to retrieve information about your existing Tomba API keys. | | `TOMBA_LEADS_CREATE` | Create Lead | Create a new lead in Tomba's lead database. Use this to store contact information for a person you want to track. Returns the unique ID of the created lead. Required fields: first_name, email. All other fields are optional. | | `TOMBA_LEADS_LIST` | List Leads | Tool to list all leads. Use when you need to retrieve and paginate your leads list. | | `TOMBA_LISTS_DELETE` | Delete Leads List by ID | Tool to delete a leads list by ID. Use when you need to permanently remove a list after confirming its ID. | | `TOMBA_LISTS_LIST` | List Lead Lists | Tool to list all lead lists. Use when you need to retrieve and paginate your lead lists. | | `TOMBA_LISTS_UPDATE` | Update Leads List | Tool to update a leads list's name by ID. Use when renaming an existing list after obtaining its ID. | | `TOMBA_USAGE_STATS` | Get Usage Statistics | Tool to get API usage statistics. Use when you need to monitor account usage and avoid hitting limits. | ## 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 Tomba from Atomic Agent With your account connected, ask Atomic Agent to work with Tomba in natural language. You can connect more apps through the same Composio integration as you need them.

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