### Description (declared)

# vin-decode-mcp

**Decode VINs and query vehicle data from a curated NHTSA vPIC database — powered by the Model Context Protocol.**

A standalone, offline-capable MCP server for LLMs to decode Vehicle Identification Numbers (VINs) and look up makes, models, and vehicle specifications using data from [NHTSA's vPIC](https://vpic.nhtsa.dot.gov/).

```
pip install vin-decode-mcp
vin-decode-mcp  # Start the MCP server
```

## Why?

- **Offline**: Works without internet access. The curated SQLite database (~4.5 MB) is self-contained.
- **No rate limits**: Unlike calling the vPIC API directly, local queries are unlimited.
- **Fast**: Pattern matching against the SQLite database takes microseconds.
- **LLM-native**: Tools with rich docstrings, schema resources, and structured JSON output.
- **Open data**: NHTSA vPIC is US government open data — free, no API key required.

## Data Coverage

- US-market vehicles, model year **1981 and forward**
- **536 makes**, **9,284 models**, **88,267 VIN patterns** (2026-08 vintage)
- Passenger Cars, Trucks, MPVs, Motorcycles, Off-Road Vehicles
- Excludes: Buses, Trailers, Low-Speed Vehicles, Incomplete Vehicles

> **Specifications only** — this database does not include title, accident, odometer,
> or theft history (those require NMVTIS/commercial data sources).

## Quick Start

### Installation

```bash
pip install vin-decode-mcp
```

Or from source:

```bash
git clone https://github.com/<org>/vin-decode-mcp.git
cd vin-decode-mcp
pip install -e .
```

### Running

```bash
# Default: stdio transport (for Claude Desktop, Cursor, etc.)
vin-decode-mcp

# HTTP transport
vin-decode-mcp --transport http --port 8765
```

### Using with Claude Desktop

Create a dedicated venv so the binary lands where you can reference it:

```bash
python3 -m venv ~/.local/venvs/vin-decode
source ~/.local/venvs/vin-decode/bin/activate
pip install vin-decode-mcp
deactivate
```

Add to `~/.config/claude-desktop/config.json` (or `~/Library/Application Support/cla…
