# Toolora

> Free online tools and a free MCP server for AI agents. Not a prompt wrapper — a real server that processes files, generates PDFs, runs OCR, and returns structured results. Used in Claude workflows across 15 countries. Listed in the Anthropic MCP Registry. Privacy-first: all browser tools run 100% client-side, nothing stored.

## Overview

Toolora (https://toolora.dev) provides three things:

1. **Free browser tools** — 28 utilities that run entirely in the browser. No uploads, no accounts, no data stored.
2. **Free MCP server** — 17 tools for Claude Desktop, Cursor, Windsurf, and any MCP-compatible AI agent. No API key required.
3. **Paid Agent API** — Server-side endpoints for document and web content processing, gated by the x402 micropayment protocol. Agents pay per request using Stellar XLM or Solana USDC.
