Overview

AI-generated overview

Remote PNG.now server that lets an assistant compress PNGs and convert images to or from other image and document formats via a hosted API.

What you can do
  • Search the live converter catalog for valid converter slugs such as png-to-jpg, png-to-webp, png-to-pdf or compress-png
  • Submit a publicly accessible image URL to a chosen converter and optionally wait for the result
  • Check the status of a conversion job and get a temporary download URL when it completes
  • Review the caller's API credits, usage and rate limit
When to use it
Useful when an assistant needs to compress PNG files or convert images between formats like JPG, WebP or PDF without running conversion software locally, and the images are reachable over the public web.
Requirements
A remote endpoint at png.now over streamable HTTP; no local package. A PNG.now API key supplied in the X-API-Key header. The source image must be at a publicly accessible URL; private-network URLs and URLs with embedded credentials are rejected.
Before you install
The API key in X-API-Key is a secret and should be kept out of logs and shared transcripts. Conversions consume API credits, so usage and rate limits are worth checking. Image URLs are sent to the PNG.now service, so avoid pointing it at sensitive or internal resources; download links returned for completed jobs are temporary.

Installation

In SourceWeft

  1. Open PNG.now MCP Server in the dashboard and add it to a workspace.
  2. Connect X-API-Key credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.chrisyau83%2Fpng-now/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
