# MCP Server
vatcheckapi ships a hosted Model Context Protocol (opens new window) (MCP) server, so AI agents and assistants can call the API as native tools — no SDK or glue code required.
https://api.vatcheckapi.com/mcp
The endpoint speaks the streamable HTTP transport. Listing the available tools works without authentication; executing a tool requires your API key, sent as the apikey header. You can get a free API key here (opens new window).
# Connect
Using Claude Code:
claude mcp add --transport http vatcheckapi https://api.vatcheckapi.com/mcp --header "apikey: YOUR_API_KEY"
Or add the server to any MCP-capable client (Claude Desktop, Cursor, VS Code, ...):
{
"mcpServers": {
"vatcheckapi": {
"url": "https://api.vatcheckapi.com/mcp",
"headers": { "apikey": "YOUR_API_KEY" }
}
}
}
# Available tools
The tools are generated from the same OpenAPI specification (opens new window) that describes the REST API, so they always match the documented endpoints, parameters and responses.
| Tool | Endpoint | Description |
|---|---|---|
check | GET /v2/check | Check a VAT number |
listBatches | GET /v2/batches | List batches |
createBatch | POST /v2/batches | Create a batch |
getBatch | GET /v2/batches/{batchId} | Get a batch |
getBatchValidations | GET /v2/batches/{batchId}/validations | List batch validations |
getStatus | GET /v2/status | Account quota status |
# Quotas and errors
Tool calls are metered exactly like REST requests: they consume your plan quota and return the same status codes and error responses (401, 422, 429, ...). If a call fails, the tool result contains the API's error message including hints on how to proceed.
