About Skill Doc Generator

MCP server that turns any documentation URL into a Claude Code skill file. No API key required — the agent does the reasoning, the server handles fetching and saving

#claude-code #skills

Config

Add this server to your MCP-compatible client using the configuration below.

{
  "mcpServers": {
    "skill-doc-generator": {
      "command": "npx",
      "args": [
        "skill-doc-generator"
      ]
    }
  }
}

Tools

Fetches a documentation page and returns its text content and all same-domain links. Call this on the initial URL, then decide which linked pages to fetch next based on the returned links.

Saves a Claude Code skill markdown file to disk. Call this once you have generated the skill content from the documentation. IMPORTANT — 500-line limit: SKILL.md must never exceed 500 lines. If the full skill content would exceed 500 lines, split it into multiple files: keep the frontmatter and a concise overview in SKILL.md (under 500 lines), put detailed sections (API reference, examples, patterns, etc.) in separate .md files passed via extra_files, and add a '## Additional References' section in SKILL.md that links to them with relative paths, e.g. [API Reference](./reference.md).

Fetches key files from a GitHub repository (README, docs, examples) using the GitHub API. More reliable than web scraping for repos with good inline documentation. Set GITHUB_TOKEN env var to avoid rate limits (60 req/h unauthenticated, 5000 with token). Use this instead of fetch_doc_page when the user provides a GitHub URL.

Reads an existing skill file from disk. Call this before updating a skill to retrieve its current content, then fetch updated docs and call save_skill with the merged result.

Returns skill-creator instructions so you can create, improve, or evaluate Claude Code skills. Call with no arguments to get the main SKILL.md. Use the 'section' parameter to retrieve subagent instructions (grader, comparator, analyzer) or the JSON schema reference.

Overview

What is Skill Doc Generator?

Skill Doc Generator is an MCP server that converts any documentation URL into a Claude Code skill file and bundles the full skill‑creator workflow. It requires no API key and works with any MCP‑compatible IDE (Claude Code, Cursor, Windsurf, etc.).

How to use Skill Doc Generator?

Install directly from npm with Node.js 18+. Add it to your MCP config—either via claude mcp add --transport stdio --scope user skill-doc-generator npx skill-doc-generator or by adding the JSON entry to your IDE’s MCP config file. Then ask your agent to generate a skill from a documentation URL or GitHub repository. Tools include fetch_doc_page, fetch_github_repo, save_skill, read_skill, and get_skill_creator.

Saves generated skills as markdown files ready for Claude Code.
Bundles the complete skill‑creator workflow for testing and iteration.
No external AI API calls are made inside the server.

Use cases of Skill Doc Generator

Generate a Claude Code skill from any documentation URL (e.g., Laravel, Stripe, Python asyncio).
Create a skill from a GitHub repository’s README, docs, and examples.
Update an existing skill with the latest documentation changes.
Build or improve skills using the built‑in skill‑creator workflow (draft → test → grade → iterate).

FAQ from Skill Doc Generator

No. The server itself never calls external AI APIs; all reasoning is done by the AI agent. No API key is needed.

What runtime dependencies does Skill Doc Generator need?

Node.js 18+ and an MCP‑compatible agentic IDE (Claude Code, Cursor, Windsurf, or VS Code with Copilot).

How can I avoid rate limits when fetching GitHub repos?

Set the GITHUB_TOKEN environment variable. The fetch_github_repo tool uses the GitHub API, and a token helps avoid rate limits.

Where are generated skills saved?

By default, skills are saved to ~/.claude/skills/. You can specify a custom output_dir when using save_skill.

What transport does Skill Doc Generator use?

It connects using stdio transport, as shown in the installation commands.
