The Gamma MCP currently only supports creating new documents and presentations via the generate tool. There's no way to amend, update, or edit an existing Gamma after it's been created — the available tools are limited to generate, read_gamma, get_folders, and get_themes. This means any change, no matter how small, requires either manually editing in the Gamma web editor or regenerating the entire document from scratch (which creates a new file, loses any manual tweaks, and clutters the workspace).lease add tools to the Gamma MCP that allow: Updating an existing Gamma by ID — amend specific cards/sections, update text, replace tables, change dates, etc. without creating a new file Appending cards to an existing document or deck Replacing individual cards in place, so manual formatting on other cards is preserved This would make Gamma genuinely usable as part of an iterative AI-assisted workflow, rather than a one-shot generator.
