SuperDocs Plugin for Claude Code

The fastest way to install SuperDocs in Claude Code. One command, one prompt for your API key, three things installed at once: the MCP server, the workflow prompts, and the skill.

​
What you get

ComponentCountWhat it does
MCP tools21Chat, structural editing, attachments, sessions, jobs, templates, pre-signed upload/download
Workflow prompts4/superdocs:draft_from_outline, /superdocs:edit_styled_docx, /superdocs:convert_format, /superdocs:review_contract_for_redflags
Skill1Auto-loads when you ask Claude to edit, draft, or export documents — no need to think about which tool to use

​
Install

claude plugin install superdocsapp/superdocs-plugin
You’ll be prompted for your sk_… API key. Get one from use.superdocs.app → Settings → API Keys → Create. Free plan includes 500 AI operations per month. The key is stored in your OS keychain (macOS Keychain, Windows Credential Manager, Linux Secret Service) — never in plaintext config.

​
Verify

claude plugin list
You should see superdocs in the list. Then in a Claude Code session, type / and you’ll see the 4 workflow prompts in the slash menu. To test the connection:
“Use the SuperDocs health tool to check the API”
If you see {"status": "healthy"}, everything works.

​
Use it

After install, just ask Claude to do document work. The skill auto-loads and Claude reaches for SuperDocs: 
"Edit /Users/me/contracts/draft.docx — make all H2 headings bold and add a new section at the end called 'Approvals'."

"Draft an NDA between Acme Corp and Globex Industries, governed by Delaware law, 2-year term."
Or invoke a workflow prompt directly: 
/superdocs:draft_from_outline

​
Updates

The plugin auto-updates when a new version is published. To pin a specific version: 
claude plugin install superdocsapp/superdocs-plugin@1.0.0
To uninstall: 
claude plugin uninstall superdocs

​
Troubleshooting

“No commands match /superdocs:” — The plugin didn’t load. Check claude plugin list and reinstall if missing. Restart Claude Code (the plugin loads at session start). “401 Unauthorized” on tool calls — API key is wrong or revoked. Reinstall the plugin or update the key with claude plugin config superdocs api_key. Tools work but skill doesn’t auto-load — The skill loads probabilistically based on your prompt phrasing. If you want to force it, mention “use SuperDocs” explicitly. Stale prompt content after a SuperDocs backend update — Run claude plugin update superdocs to pull the latest plugin version.

​
What’s bundled vs. backend-served

The plugin itself is small — just the manifest + the skill markdown. The 21 tools and 4 prompts are served live from https://api.superdocs.app/mcp/ (Streamable HTTP, sk_ Bearer auth). Tool descriptions, prompt templates, and behavior changes ship from the backend instantly — no plugin update needed for those. The plugin’s job is to make install painless. The smarts live on the server.

​
Source

The plugin is open source under MIT. Browse, clone, fork, or report issues at github.com/superdocsapp/superdocs-plugin.

​
Manual install (without the plugin)

For cases where you can’t use plugins (older Claude Code, project-scoped .mcp.json shared via git, etc.), see the Claude Code manual setup section.
