Introduction

Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows.

This guide explains the easiest and most robust way to connect your Moneybird account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either.

What is Composio Connect?

Composio Connect is a consumer offering that lets anyone plug 1,000+ applications directly into their agent harness — including Hermes. It can:

  • Search and load tools from relevant toolkits on-demand, reducing context usage.
  • Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
  • Manage app authentication end-to-end with zero manual overhead.

Integrating Moneybird with Hermes

Using Composio Connect CLI

1. Install the Composio CLI

Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you.

bash
curl -fsSL https://composio.dev/install | bash
Hermes authenticating with Composio

2. Authenticate

Once the CLI is installed, ask Hermes to authenticate with Composio.

3. Connect to Moneybird

Ask your agent to connect to Moneybird, or simply request any Moneybird-related task. Hermes will prompt you to authenticate and authorize access.

4. Done. You're all set with a new Moneybird connection.

Using Composio Connect MCP

1. Get your MCP URL and API Key

Go to dashboard.composio.dev and copy your Connect MCP URL and API key.

Copy MCP URL and API key from Composio dashboard

2. Open the Hermes config file

bash
nano ~/.hermes/config.yaml

3. Add the Composio Connect MCP server

bash
mcp_servers:
  composio:
    url: "https://connect.composio.dev/mcp"
    headers:
      x-consumer-api-key: "YOUR_COMPOSIO_API_KEY"
    connect_timeout: 60
    timeout: 180

Save with Ctrl + O, Enter, then exit with Ctrl + X.

4. Restart your Hermes agent

Once restarted, ask your agent to connect to Moneybird or request any Moneybird-related task. It will prompt you to authenticate and authorize access.

5. Done!

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.

Way Forward

With Moneybird connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to.

From here, you can extend Hermes further:

  • Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you.
  • Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
  • Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

FAQ

What are the differences in Tool Router MCP and Moneybird MCP?

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 Hermes?

Yes, you can. Hermes 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.
