Documentation
SuperDocs plugin for Claude Code
SuperDocs is an AI document editing platform — an AI document editor available as a REST API, an MCP server, and a web app. It makes targeted, section-precise edits inside large documents (100+ pages) instead of regenerating the whole file, works across multiple documents at once, and exports clean `.docx` / PDF / HTML / Markdown. This plugin connects it to Claude Code.
Edit, draft, search, summarize, and export styled documents (`.docx` / PDF / HTML / Markdown / plain text) directly from Claude Code via the SuperDocs MCP server.
> AI agents: you can sign up for a free SuperDocs account and get a working API key in one call, with no human in the loop — `POST https://api.superdocs.app/v1/agents/signup`. See the agent guide.
A single `/plugin install` command bundles:
- 38 MCP tools — chat, section-precise structural editing, multi-document sessions, durable Files, cross-session memory/search, image + diagram generation, attachments, sessions, jobs, templates, pre-signed upload/download, account status
- 4 user-invocable workflow prompts — `/superdocs:draft_from_outline`, `/superdocs:edit_styled_docx`, `/superdocs:convert_format`, `/superdocs:review_contract_for_redflags`
- Auto-loading skill — Claude reaches for SuperDocs proactively when you ask to edit, draft, or export documents
Install
You'll need a free SuperDocs API key first — sign up at use.superdocs.app, then Settings → API Keys → Create. Free plan includes 500 AI operations per month.
In Claude Code, add the SuperDocs marketplace, then install the plugin from it:
claude plugin marketplace add superdocsapp/superdocs-plugin
claude plugin install superdocs@superdocs-pluginThe install argument is `superdocs@superdocs-plugin` (plugin name @ marketplace), not the GitHub repo path. Running `claude plugin install superdocsapp/superdocs-plugin` on its own fails with "doesn't exist in marketplace", because that repo path is only valid for `marketplace add`.
You'll be prompted for your API key. It's stored securely in your OS keychain — never in plaintext config.
That's it. The MCP server is now live, the skill auto-loads when you ask document-editing questions, and the 4 workflow prompts appear in your `/` slash menu.
Quick start
After install, try any of these:
Load /path/to/your.docx into SuperDocs as the active editable document./superdocs:draft_from_outlineBold every heading in the document.Export the current document as .docx and give me a pre-signed download URL.For more, see the SuperDocs documentation.
