VIN MCP Server

Give AI agents a direct VIN lookup tool.

VINState MCP wraps the existing VIN API in a Model Context Protocol endpoint, so agent clients can call one tool, decode one VIN, and stay inside the same free or paid account limits.

Transport

POST /mcp

One HTTP endpoint accepts MCP JSON-RPC requests and returns tool results.

Auth

Bearer API key

Use the same API key you already manage in the VINState console.

Billing

Successful lookup only

Valid successful VIN lookups consume included quota first, then credits.

Tools

Two MCP tools, one billing model

Both tools accept a single vin argument. The free tool is a friendly entry point for trials; production users can call vin.decode directly.

Tool

vin.decode_free

Best for free-tier testing, demos, and light agent workflows.
