## 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 Smol Machines 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.

- [Atomic Agent](https://composio.dev/toolkits/smol_machines/framework/atomic-agent)

## TL;DR

### What is Composio Connect?
Composio Connect is a consumer offering that lets anyone plug 1,500+ 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.

## Connect Smol Machines to Hermes

### Integrating Smol Machines 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
```

## What is the Smol Machines MCP server, and what's possible with it?

The Smol Machines MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Smol Machines account. It provides structured and secure access to isolated Smol Cloud machines, file transfer, bounded command execution, and account and usage information, so your agent can create, start, stop, inspect, and operate machines on your behalf.
- Machine lifecycle management: Have your agent create machines with defined resources, automatic stop and deletion settings, and network policies, then start, stop, or permanently delete them.
- Bounded command execution: Let the agent run foreground commands on a hosted machine for tasks such as setup, diagnostics, and controlled workloads.
- File transfer: Direct your agent to upload files to a machine or download files from it when moving code, data, or generated results.
- Machine inspection: Instruct your agent to list machines, filter them by labels, and check their configuration, lifecycle state, and readiness.
- Usage and account tracking: Have your agent review account limits, plan details, billing-period usage, and machine-level usage and costs.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `SMOL_MACHINES_CREATE_MACHINE` | Create Machine | Create one bounded Smol Cloud machine in the stopped state with explicit resources, a finite auto-stop interval and deletion TTL, and an explicit outbound network policy. Published ports remain authenticated by default. The conservative blocked default denies egress and may prevent uncached image pulls; unrestricted networking and unauthenticated public ingress each require explicit opt-in. |
| `SMOL_MACHINES_DELETE_MACHINE` | Delete Machine | Permanently delete one Smol Cloud machine by its exact machine ID. This irreversible operation removes all machine-local storage, ends its storage billing, and requires explicit confirmation. Export important data before calling this tool. Do not automatically retry after an ambiguous failure. |
| `SMOL_MACHINES_DOWNLOAD_FILE` | Download File | Download and offload one file from an exact cloud machine. Downloads are limited to 10 MB by Composio policy, and the read resets the machine's auto-stop idle timer. |
| `SMOL_MACHINES_EXEC_COMMAND` | Execute Command | Run one bounded foreground argv command on an exact hosted Smol Cloud machine. Execution can auto-start billable compute and can modify or delete guest data. Output is text-only, streaming and background execution are disabled, and the action never retries automatically. |
| `SMOL_MACHINES_GET_ACCOUNT` | Get Account | Get the connected account's status, plan, effective machine limits, billing-period usage, and spend in integer micros. |
| `SMOL_MACHINES_GET_ACCOUNT_USAGE` | Get Account Usage | Get metered usage for the connected account's provider-defined period, keeping the requested and consumed metric windows distinct. |
| `SMOL_MACHINES_GET_MACHINE` | Get Machine | Get configuration, lifecycle state, and readiness for one cloud machine by its exact machine id, not by name. |
| `SMOL_MACHINES_GET_MACHINE_USAGE` | Get Machine Usage | Get billing-period usage and cost in integer micros for one exact machine ID. CPU and memory metering can lag by several minutes while a machine is running, so mid-life usage and cost are a lower bound until metering rolls up; stop and delete trigger a final sample. Deleted machine usage remains available for the provider-documented 30-day lookup period. |
| `SMOL_MACHINES_LIST_MACHINES` | List Machines | List cloud machines owned by the connected account, optionally requiring all supplied labels to match. |
| `SMOL_MACHINES_START_MACHINE` | Start Machine | Start one stopped cloud machine by exact machine ID. A detached start returns before readiness and requires polling GET_MACHINE until ready=true. |
| `SMOL_MACHINES_STOP_MACHINE` | Stop Machine | Stop compute for one cloud machine by exact id while preserving its filesystem. Stopping does not delete the machine: stored disk can continue billing and the machine can continue occupying a plan slot until deletion. |
| `SMOL_MACHINES_UPLOAD_FILE` | Upload File | Upload a file of at most 8,000,000 bytes to a safe relative guest path on one cloud machine identified by its exact machine ID. This can replace existing guest data and resets the machine's auto-stop idle timer. |

## Conclusion

### Way Forward
With Smol Machines 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.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Smol Machines MCP?

With a standalone Smol Machines MCP server, the agents and LLMs can only access a fixed set of Smol Machines tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Smol Machines 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 Smol Machines tools.

### Can I manage the permissions and scopes for Smol Machines while using Tool Router?

Yes, absolutely. You can configure which Smol Machines 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 Smol Machines data and credentials are handled as safely as possible.
