DocsForAI

MCP Tools

Crawl and read documentation websites using DocsForAI. Use when you need to learn a new library, framework, or tool by reading its official docs; when you want to look up how something works from documentation; when writing or debugging code that requires understanding of a specific SDK/API; when the user asks you to "read the docs", "check the documentation", or "learn how to use X". Supports VitePress, Docsify, Mintlify, Docusaurus, mdBook, MkDocs, Starlight, GitBook, Feishu Docs, and generic sites. Auto-detects framework type.

DocsForAI — Documentation Crawler Skill

Crawl any documentation website into structured, persistent Markdown files and read them on demand — so you always work from accurate, up-to-date documentation rather than training-data guesses.

Source: https://pypi.org/project/docsforai/ | https://github.com/dx2331lxz/DocsForAI | Latest: 0.6.0

Install (one-time)

uv tool install docsforai   # recommended: isolated, no system Python pollution
pip install --break-system-packages docsforai  # fallback if uv unavailable

Verify: docsforai --version

Core Principles

Always use multi-md format. It preserves the site's original chapter hierarchy as individual files, so you can navigate to exactly the section you need without loading the entire documentation into context.

Output rule: docsforai writes directly to <output>/<site-name>/ — no extra subdirectory is created.

Docs are persistent. Once crawled, they live on disk across sessions. Check before crawling; never re-crawl what already exists.

Workflow

Step 1 — Check if docs already exist

Before doing anything else, check both the local filesystem and MEMORY.md:

ls ~/.openclaw/workspace/skills/docsforai/docs/

Also look up the 「已下载文档（DocsForAI）」 section in MEMORY.md for a record of previously crawled sites and their paths.

If the site folder already exists → skip to Step 3.

Step 2 — Crawl (only if not already downloaded)

Always pass the skill's docs/ directory as -o. DocsForAI creates <site-name>/ inside it automatically.

docsforai crawl <URL> -f multi-md \
  -o ~/.openclaw/workspace/skills/docsforai/docs

Common examples:

URL	Site name	Final path
https://vitepress.dev/guide	`vitepress`	`docs/vitepress/`
https://docs.pydantic.dev	`pydantic`	`docs/pydantic/`
https://docusaurus.io/docs	`docusaurus`	`docs/docusaurus/`
https://react.dev/learn	`react`	`docs/react/`
https://docs.python.org/3	`python`	`docs/python/`

After crawling completes, proceed to Step 2b.

Step 2b — Record to MEMORY.md (required)

Append a row to the 「已下载文档（DocsForAI）」section in MEMORY.md. Create the section if it doesn't exist yet:

## 已下载文档（DocsForAI）

| Site | Local path | Crawled |
|---|---|---|
| vitepress | ~/.openclaw/workspace/skills/docsforai/docs/vitepress/ | 2026-04-02 |

Never overwrite existing rows — always append.

Step 3 — Map the structure

Before reading any file, get a full picture of the directory tree:

find ~/.openclaw/workspace/skills/docsforai/docs/<site-name> -name "*.md" | sort

Scan the output. Identify which subdirectories and files correspond to the topic you need. This costs nothing and saves you from loading irrelevant chapters.

Step 4 — Read on demand (the most important step)

Load only what is directly relevant to the current task. Follow this decision tree:

4a. You need a quick orientation

Read the top-level index first:

read ~/.openclaw/workspace/skills/docsforai/docs/<site-name>/index.md

4b. You know roughly what you need

Read the specific chapter file directly:

read ~/.openclaw/workspace/skills/docsforai/docs/<site-name>/guide/configuration.md
read ~/.openclaw/workspace/skills/docsforai/docs/<site-name>/reference/api.md

4c. You need to find where something is documented

Search across all files for a keyword, then read only the matching file:

# Find which file covers a specific topic
grep -rl "defineConfig\|plugin\|vite" \
  ~/.openclaw/workspace/skills/docsforai/docs/<site-name>/ | head -10

4d. You need to understand a full feature area

Read the section index, then follow up with the specific sub-pages you need:

# Read section overview
read ~/.openclaw/workspace/skills/docsforai/docs/<site-name>/guide/index.md

# Then read only the sub-pages that apply
read ~/.openclaw/workspace/skills/docsforai/docs/<site-name>/guide/routing.md

Rules:

Never read the entire docs tree in one go
Stop reading once you have enough to proceed
If you read something and it's not what you needed, search more precisely rather than loading more files

When to Consult Docs (decision guide)

Use this skill proactively whenever you are about to:

Situation	Action
Use an API you haven't used in this session	Read the relevant API reference page
Write configuration for a framework	Read the configuration guide
Debug an unexpected behavior	Search docs for the error or behavior, read matching section
Use a CLI tool you're unfamiliar with	Read the CLI reference page
Implement a non-trivial feature	Read the feature's guide page before writing code
Upgrade a library version	Check migration or changelog docs first

Do not guess at API signatures, config options, or CLI flags when the docs are available on disk. A 2-second read beats a hallucinated parameter.

CLI Reference

# Standard crawl
docsforai crawl <URL> -f multi-md -o <output-dir>

# Force framework type (skip auto-detection)
docsforai crawl <URL> --type nextdocs -f multi-md -o <output-dir>
docsforai crawl <URL> --type mkdocs -f multi-md -o <output-dir>

# Polite crawling (for rate-sensitive sites)
docsforai crawl <URL> -f multi-md --concurrency 2 --delay 0.5 -o <output-dir>

# Limit pages (generic mode only)
docsforai crawl <URL> -f multi-md --max-pages 100 -o <output-dir>

Supported Frameworks (auto-detected)

Framework	Detection signal
VitePress	`.VPSidebar` CSS class / generator meta
Docsify	`$docsify` global variable — fetches raw `.md` source
Mintlify	`x-llms-txt` response header — single request for full content
Docusaurus	generator meta / `.theme-doc-sidebar-container`
mdBook	`#mdbook-sidebar` / `ol.chapter`
MkDocs	generator meta / `.md-nav--primary` (Material + default themes)
Starlight	`#starlight__sidebar` / `.sl-markdown-content`
GitBook	generator meta `GitBook` / sitemap-based discovery
NextDocs	`/_next/` assets + `.mdx-content` — sitemap discovery + sidebar fallback
Feishu Docs	`open.feishu.cn` domain — internal API
Generic	BFS link traversal — fallback for any other site

Tips

Mintlify sites fetch everything in one request — near-instant
Cloudflare-protected sites — DocsForAI auto-retries with system curl
Count total pages: find ~/.openclaw/workspace/skills/docsforai/docs/<site> -name "*.md" | wc -l
Re-crawl to refresh: delete the site folder first, then crawl again
