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-plugin

The 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_outline

Bold 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.

What this plugin includes

Manual install (no plugin)

If you'd rather configure the MCP server directly without the plugin (e.g., to share a config across projects via .mcp.json), see the MCP setup docs.

Updates

Plugin auto-updates whenever a new version is published. To pull the latest immediately, run claude plugin update superdocs.

Compatibility

For non-Claude-Code clients, install the MCP server directly per the SuperDocs MCP setup docs.
