quickdocs

Instant documentation fetcher for any developer service. One command — get the docs.

Powered by llms.txt. Works as a CLI, MCP server (Claude Code, Cursor, Windsurf), and Claude Code hook (/docs).

Install

npm install -g quickdocs

Or without installing:

npx quickdocs stripe webhooks

CLI Usage

quickdocs stripe webhooks           # fetch docs — trimmed to relevant sections
quickdocs nextjs app-router
quickdocs supabase auth
quickdocs react useEffect
quickdocs vercel environment-variables

Interactive mode

quickdocs

Arrow-key picker → select service → select topic → docs printed.

Options

quickdocs stripe webhooks --full    # full doc, no trimming
quickdocs stripe webhooks --fresh   # skip cache, fetch live
quickdocs stripe --list             # browse all topics for a service
quickdocs list                      # list all supported services
quickdocs cache:clear               # clear ~/.quickdocs/cache/

Smart Trimming

By default, quickdocs returns only the relevant sections for your topic — not the entire doc page.

Splits the page by headings → scores each section against your query → returns top matches (~4000 chars).

quickdocs stripe webhooks           # relevant sections only
quickdocs stripe webhooks --full    # full page

Claude Code Hook (/docs)

Type /docs directly in Claude Code input. The hook pre-fetches docs and injects them into context — no AI tool calls needed.

Setup:

1. Add to ~/.claude/settings.json:

{
  "hooks": {
    "UserPromptSubmit": [
      {
        "matcher": "^/docs",
        "hooks": [
          {
            "type": "command",
            "command": "bash \"/path/to/quickdocs/plugin/hooks/on-prompt.sh\"",
            "timeout": 20
          }
        ]
      }
    ]
  }
}

2. Copy skill:

cp -r plugin/skill ~/.claude/skills/docs

Usage:

/docs stripe webhooks        → fetches + injects docs instantly
/docs nextjs app-router
/docs                        → shows all services
/docs stripe                 → shows all stripe topics

MCP Server (Claude Code / Cursor / Windsurf)

claude mcp add-json quickdocs '{"command":"npx","args":["-y","quickdocs","mcp"]}'

Or add to .mcp.json:

{
  "mcpServers": {
    "quickdocs": {
      "command": "npx",
      "args": ["-y", "quickdocs", "mcp"]
    }
  }
}

Cursor → ~/.cursor/mcp.json | Windsurf → ~/.codeium/windsurf/mcp_config.json

MCP Tools

| Tool | Description | |------|-------------| | get_docs(service, topic) | Fetch docs — trimmed by default, full=true for complete | | list_services() | List all supported services | | list_topics(service) | Browse all topics for a service | | search_topics(service, query) | Search topics by keyword |

Supported Services

All services use the official llms.txt standard — no scraping.

| Service | Aliases | |---------|---------| | Stripe | stripe | | Vercel | vercel | | Next.js | nextjs, next | | Supabase | supabase | | Anthropic | anthropic, claude | | GitHub | github, gh | | Drizzle ORM | drizzle | | Cloudflare | cloudflare, cf | | Docker | docker | | Astro | astro | | Svelte / SvelteKit | svelte, sveltekit | | Hono | hono | | Bun | bun | | Deno | deno | | Prisma | prisma | | Clerk | clerk | | Neon | neon, neondb | | Upstash | upstash | | Turso | turso | | shadcn/ui | shadcn, shadcn-ui | | Model Context Protocol | mcp | | Vercel AI SDK | ai-sdk, aisdk | | LangChain | langchain | | Turborepo | turborepo, turbo | | Replicate | replicate | | PostHog | posthog | | Cursor | cursor | | Better Auth | better-auth |

How it works

Fetch official llms.txt index → fuzzy-match topic → fetch .md doc directly.

Caching

Cached at ~/.quickdocs/cache/ for 24h. Use --fresh to bypass.

Contributing

Add a service — one object in src/registry/services.ts:

myservice: {
  name: 'My Service',
  aliases: ['myservice', 'ms'],
  baseUrl: 'https://docs.myservice.com',
  llmsTxtUrl: 'https://docs.myservice.com/llms.txt',
  strategy: 'llmstxt',
  description: 'What this service does',
},
