## 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 CarsXE 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.

## TL;DR

### 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.

## Connect CarsXE to Hermes

### Integrating CarsXE 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 CarsXE MCP server, and what's possible with it?

The CarsXE MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your CarsXE account. It provides structured and secure access so your agent can perform CarsXE operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CARSXE_CHECK_LIEN_AND_THEFT` | Check Lien and Theft Records | Retrieve reportable US lien and theft events for a VIN. A no-data response means CarsXE has no reportable record and is not proof that the vehicle is clear. |
| `CARSXE_DECODE_LICENSE_PLATE` | Decode License Plate | Look up vehicle identity from a license plate using CarsXE's current global v2 decoder. |
| `CARSXE_DECODE_OBD_CODE` | Decode OBD Code | Translate an OBD-II diagnostic trouble code into a readable diagnosis. |
| `CARSXE_GET_MARKET_VALUE` | Get Vehicle Market Value | Estimate wholesale, retail, and trade-in values for a VIN using CarsXE's current v2 valuation, optionally adjusted for state, mileage, and condition. |
| `CARSXE_GET_RECALL_BATCH` | Get Recall Batch | Make exactly one read request for a CarsXE recall batch. The default status view returns current progress. The results view is available only when the batch is completed or partial and returns a bounded local page (100 rows by default, at most 1,000) from CarsXE's complete array; use result_offset to continue. CarsXE returns 409 while results are not ready. This tool makes one provider request and never polls internally. |
| `CARSXE_GET_VEHICLE_HISTORY` | Get Vehicle History | Retrieve title, brand, junk/salvage, insurance, VIN-change, and historical title records for a VIN. |
| `CARSXE_GET_VEHICLE_IMAGES` | Get Vehicle Images | Find up to 10 vehicle photos by make and model, with optional year, trim, angle, image type, size, color, quality, transparency, and license filters. |
| `CARSXE_GET_VEHICLE_RECALLS` | Get Vehicle Recalls | Find safety recall campaigns either for one VIN or for a year, make, and model. Supply exactly one lookup method. |
| `CARSXE_GET_VEHICLE_SPECS` | Get Vehicle Specifications | Decode a 17-character VIN into vehicle identity, specifications, equipment, colors, and warranty data. International decoding is used automatically when CarsXE needs it unless explicitly disabled. |
| `CARSXE_GET_YEAR_MAKE_MODEL_DATA` | Get Year Make Model Data | Look up detailed vehicle and trim information by year, make, and model without a VIN. Returns bounded trim summaries rather than large feature and color payloads. |
| `CARSXE_RECOGNIZE_LICENSE_PLATE` | Recognize License Plate | Analyze a publicly accessible vehicle image and return license-plate candidates, regions, confidence, bounding boxes, and detected vehicle details. |
| `CARSXE_SUBMIT_RECALL_BATCH` | Submit Recall Batch | Create one asynchronous CarsXE recall-check batch for 1 to 10,000 VIN entries. Submission charges one Recalls Batch unit per unique valid VIN after CarsXE normalizes and deduplicates the list. The action makes one submission request and does not poll or resubmit an ambiguous failure; use the returned batch ID to check progress or retrieve results later. |

## Creating MCP Server - Stand-alone vs Composio SDK

The CarsXE MCP server provides comprehensive access to CarsXE operations through Composio. Once connected, Hermes can perform all major CarsXE actions on your behalf using natural language commands.

## Conclusion

### Way Forward
With CarsXE 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 CarsXE MCP?

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

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

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