Quickhelp

What is Quickhelp?

Quickhelp is a collection of 15 free developer tools — each with a browser UI, a REST API, and an MCP endpoint — so that AI agents (Claude, Cursor, Continue, etc.) and humans can access them without any sign-up. It is designed for developers who need quick, stateless utilities like JWT decoding, image conversion, or hashing, all accessible via the Model Context Protocol.

How to use Quickhelp?

Add the MCP server to Claude Desktop by installing the npm package quickhelp-mcp and configuring claude_desktop_config.json with the command npx -y quickhelp-mcp. For other MCP clients (including Claude Code CLI), use POST https://quickhelp.dev/mcp with JSON-RPC 2.0 requests, or run claude mcp add --transport http quickhelp https://quickhelp.dev/mcp. Tools can also be used directly via their REST API endpoints (POST /api/<slug>) or through the web UI at quickhelp.dev.

How does Quickhelp handle image processing?

Image processing (conversion, resizing, background removal) runs entirely in your browser using WebAssembly. No images are uploaded to any server.

Can I use Quickhelp with my own AI agent or application?

Yes. The MCP endpoint at POST https://quickhelp.dev/mcp works with any MCP‑compatible client. Additionally, every tool exposes a REST API (POST /api/<slug>) with JSON in/out, documented via OpenAPI 3.1 at /openapi.json.

Is there a rate limit or paid plan?

The free tier allows 30 requests per 60 seconds per anonymous user. Outputs may include a watermark. There is no paid plan mentioned — free tier is described as “always”.
