Identify what an AI image carries (marks, metadata, watermarks), then clean it.

Overview

AI-generated overview

Lets an assistant inspect what an AI-generated image carries, such as marks, metadata and watermarks, and then clean it.

What you can do
Demarker exposes tools to identify what an AI image carries and to clean it. The tools are demarker_identify (free, works without a key), demarker_clean (spends credits), demarker_get_balance, demarker_get_pricing and demarker_get_job. Cleaning requires a maxCredits value and a hard per-call ceiling applies regardless of what the model requests. Results are written next to the input file and never overwrite an existing file.
When to use it
Use it when you need to check whether an image carries AI marks, metadata or watermarks, or to remove them before reuse. Identification alone is free and needs no account, so it is also useful for a quick inspection pass.
Requirements
Runs locally over stdio, typically via npx @demarker/mcp. Node.js is needed for the npm package. An API key in DEMARKER_API_KEY is optional but required to clean images and read balance; DEMARKER_API_URL and DEMARKER_MCP_MAX_CREDITS are also read. Desktop clients only.
Before you install
demarker_clean spends credits, so set DEMARKER_MCP_MAX_CREDITS deliberately; the default per-call ceiling is 2. The user must confirm a rights statement before cleaning, and clients without elicitation support must pass rightsAttested: true only after explicit agreement. The API key is a secret and should not be shared.

Installation

In SourceWeft

  1. Open Demarker in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

@demarker/mcp

MCP server for Demarker: identify what an AI image carries, then clean it.

Install

  • Claude Code: claude mcp add demarker -- npx -y @demarker/mcp
  • Cursor, VS Code: one-click buttons at https://demarker.io/developers
  • Claude Desktop, Windsurf, Cline:
json
{ "mcpServers": { "demarker": { "command": "npx", "args": ["-y", "@demarker/mcp"],  "env": { "DEMARKER_API_KEY": "sk_live_YOUR_KEY" } } } }

Tools: demarker_identify (free; works without a key), demarker_clean (spends credits), demarker_get_balance, demarker_get_pricing, demarker_get_job.

Safety

  • demarker_clean needs maxCredits, and a hard per-call ceiling applies whatever the model asks for (default 2, set DEMARKER_MCP_MAX_CREDITS).
  • The user must confirm the rights statement. Clients that support elicitation show it to the user; others must pass rightsAttested: true only after the user explicitly agreed.
  • Results are written next to the input and never overwrite a file.

Env: DEMARKER_API_KEY (to clean; create at https://demarker.io/app/settings/api), DEMARKER_API_URL, DEMARKER_MCP_MAX_CREDITS.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
