## Introduction

Cowork is Anthropic's AI agent for knowledge work. Think of it as Claude Code for everything else. It works autonomously with your computer, local files, and applications to accomplish complex tasks.
This guide walks you through the easiest and most secure way to connect your CarsXE account to Cowork via Composio Connect, enabling it to decode VIN and summarize vehicle specs, check recalls for a used car, estimate market value from license plate, and more such actions on your behalf without compromising your account security.

## Also integrate CarsXE with

- [ChatGPT Work](https://composio.dev/toolkits/carsxe/framework/chatgpt)
- [Hermes](https://composio.dev/toolkits/carsxe/framework/hermes-agent)

## Connect CarsXE to Claude Cowork

### Connecting CarsXE to Claude Cowork
1. Open Customize
In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.
2. Add the Composio MCP server
Click Add custom connector and paste in the Composio MCP server URL:

```bash
https://connect.composio.dev/mcp
```

## What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.
With Composio Connect, Cowork can securely access apps like CarsXE through MCP without you sharing account credentials directly with the agent.

## 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. |

## 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 Claude Cowork?

Yes, you can. Claude Cowork 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.
