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 Moneybird account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Moneybird with - [OpenAI Agents SDK](https://composio.dev/toolkits/moneybird/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/moneybird/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/moneybird/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/moneybird/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/moneybird/framework/codex) - [OpenClaw](https://composio.dev/toolkits/moneybird/framework/openclaw) - [Hermes](https://composio.dev/toolkits/moneybird/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/moneybird/framework/google-adk) - [LangChain](https://composio.dev/toolkits/moneybird/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/moneybird/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/moneybird/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/moneybird/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/moneybird/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/moneybird/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/moneybird/framework/autogen) ## TL;DR ### How Atomic Agent connects to Moneybird 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 Moneybird to Atomic Agent ### Connect Moneybird 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 Moneybird. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Moneybird 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 Moneybird MCP server, and what's possible with it? The Moneybird MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Moneybird account. It provides structured and secure access to your invoicing and accounting data, so your agent can perform actions like creating contacts, sending invoices, managing notes, and keeping your financial records up to date on your behalf. - Automated contact creation and management: Instantly add new clients or companies, update existing records, archive unused contacts, or remove outdated information—without manual entry. - Easy invoice generation: Direct your agent to create detailed sales invoices for any contact, including custom line items, for fast and accurate billing. - Contact note and to-do tracking: Record comments, assign to-dos, and manage notes on contacts, ensuring follow-ups and client history are always at your fingertips. - Contact filtering and segmentation: Effortlessly filter and retrieve contacts based on criteria like creation date or name, making it easy to target communications or review segments of your client base. - Comprehensive contact person management: Add or remove individual contact persons linked to organizations, keeping your records detailed and up to date for every client relationship. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `MONEYBIRD_ADD_NOTE_TO_CONTACT` | Add Note to Contact | Tool to add a note or to-do to a contact.

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

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