What is the Markly MCP server?

Connect Markly to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Add text or logo watermarks to images via the Markly.cloud API. Batch supported. The markly mcp server is what makes that connection.

What the server does

MCP (Model Context Protocol) server for Markly.cloud - add watermarks to images via AI agents.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • markly_watermark_text — Add a text watermark to an image via URL
  • markly_watermark_logo — Add a logo watermark to an image via URL
  • markly_batch_watermark — Watermark up to 20 images, get a ZIP
  • markly_check_usage — Check API quota and usage stats (requires API key)

Credentials and setup notes

Configuration is passed through the environment: MARKLY_API_KEY, MARKLY_API_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Installation

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.

Where it fits

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Markly's toolset — markly_watermark_text, markly_watermark_logo, markly_batch_watermark and 1 more — is a fair guide to whether it matches your workflow. It is maintained by Whitemarmot; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Markly to MCP-compatible AI assistants such as Claude and Cursor, exposing 4 tools (markly_watermark_text, markly_watermark_logo, markly_batch_watermark, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Markly directly.
