概览

What is Gamma Watermark Remover?

Gamma Watermark Remover is an MCP (Model Context Protocol) server that allows AI agents and MCP-compatible clients to remove the "Made with Gamma" watermark from PDF and PowerPoint (.pptx) files exported from Gamma.app. It processes files entirely on the user's machine, deleting the watermark object structurally without rendering or uploading.

How to use Gamma Watermark Remover?

Install the server via uvx gamma-watermark-remover-mcp (or pipx run gamma-watermark-remover-mcp). For Claude Desktop add the configuration to claude_desktop_config.json; for Claude Code run claude mcp add gamma-watermark-remover -- uvx gamma-watermark-remover-mcp. A hosted streamable-HTTP endpoint is also available at https://gammaremover.com/mcp for clients that cannot run a local server.

常见问题

Which MCP clients does this work with?

Any client that speaks MCP over stdio or streamable HTTP: Claude Desktop, Claude Code, Cursor, Windsurf, Cline, and others.

Do my files get uploaded?

With the local stdio server, never — processing happens on your machine. The hosted endpoint receives file content (base64, up to 30MB), processes it in memory only, and stores nothing.

What file formats are supported?

PDF and PowerPoint (.pptx) exports from Gamma.app. Legacy .ppt must be converted to .pptx first.

What happens if the watermark cannot be removed?

Some exports flatten the badge into the page image. The tool reports `may_remain` honestly instead of degrading the file with pixel inpainting.

Is this free?

Yes — MIT-licensed open source, no account, no quota.
