# Taggun — how to use (mcp.ai)

Connect your Taggun account and use 14 tools for document data extraction straight from your AI agent. Connect with your own API key. Taggun is an AI-powered receipt OCR API that extracts structured data from receipt and invoice images in real-time. It supports 85+ languages, fraud detection, and automated expense tracking.

## Option A — via MCP (recommended)
Remote MCP endpoint (HTTP, streamable): `https://api.mcp.ai/p_taggun?ms=1787296020000`
Add it as a custom/remote MCP connector in your client (Claude, Cursor, VS Code…), then authenticate when prompted. Once connected, ask the agent to use the server's tools (e.g. `taggun_add_merchant_name`).

## Option B — via direct REST API
Base URL: `https://api.mcp.ai/api/taggun`
Auth: `Authorization: Bearer sk_live_…` — create a workspace API key at https://mcp.ai/settings/api-keys
Discover endpoints: `GET https://api.mcp.ai/api/taggun/_endpoints`
