# LLM Documentation Scraper (`doc-scraper`) [](https://github.com/Sriram-PR/doc-scraper/actions/workflows/ci.yml) [](https://golang.org/) [](https://pkg.go.dev/github.com/Sriram-PR/doc-scraper/v2) [](https://github.com/Sriram-PR/doc-scraper/blob/main/LICENSE) [](https://glama.ai/mcp/servers/Sriram-PR/doc-scraper) > A configurable, concurrent, and resumable web crawler written in Go. Specifically designed to scrape technical documentation websites, extract core content, convert it cleanly to Markdown format suitable for ingestion by Large Language Models (LLMs), and save the results locally.  doc-scraper crawls documentation sites into clean Markdown and serves them to coding agents over MCP. Your agent searches and reads the docs you chose, offline, instead of guessing from training data or a live web search. Point `doc-scraper add` at any docs page and it detects the framework (30+ docs generators, including Docusaurus, Starlight, Sphinx, VitePress, Material for MkDocs, and mdBook), validates the content selector, and drafts the config for you. **Documentation: https://sriram-pr.github.io/doc-scraper/** ## Features - **Offline search for agents:** BM25 full-text search (`search_docs`) and page reads (`read_page`) over the stored corpus, with no network access - **Framework detection:** 30+ docs generators recognized, each selector validated on the page, Readability fallback, JavaScript-only shells reported instead of crawled empty - **Clean output:** GitHub-Flavored Markdown per page with frontmatter, plus `pages.jsonl`, `llms.txt`, and `llms-full.txt` - **Polite and resumable:** robots.txt and sitemaps, per-host rate limits, retries with backoff, resumable crawls, and staged output that never clobbers the last good copy - **Stays fresh:** incremental re-crawls, watch mode, and crawl history (`get_freshness`, `diff_crawl`) - **Many sites at once:** parallel crawls with shared limits ## Install Download a release binary (Linux, macOS, Windows; amd64 and arm64) from the [Releases page](https://github.com/Sriram-PR/doc-scraper/releases/latest), or: ```bash go install github.com/Sriram-PR/doc-scraper/v2/cmd/doc-scraper@latest ``` ```bash docker run --rm --user "$(id -u):$(id -g)" -v "$PWD":/data ghcr.io/sriram-pr/doc-scraper:latest crawl -site rust_cli_book ``` Claude Desktop users can install `doc-scraper.mcpb` from the latest release instead. Details: [Install](https://sriram-pr.github.io/doc-scraper/getting-started/install/). ## Quick start ```bash doc-scraper add -site rust_cli_book https://rust-cli.github.io/book/index.html # detect, preview, confirm doc-scraper crawl -site rust_cli_book # Markdown lands in ./crawled_docs/rust_cli_book/ doc-scraper search -site rust_cli_book "error handling" ``` Then give it to Claude Code: ```bash claude mcp add --transport stdio doc-scraper -- /path/to/doc-scraper mcp-server -config /path/to/config.yaml ``` See [Claude Code setup](https://sriram-pr.github.io/doc-scraper/mcp/claude-code/) for scopes and a first prompt. ## Docs - [Getting started](https://sriram-pr.github.io/doc-scraper/getting-started/install/): install, quick start, adding a site - [Use with agents (MCP)](https://sriram-pr.github.io/doc-scraper/mcp/overview/): Claude Code, Claude Desktop, any stdio client, and the 11 tools - [Docs frameworks](https://sriram-pr.github.io/doc-scraper/frameworks/overview/): how detection works, with guides for Docusaurus, Starlight, Sphinx, VitePress, Material for MkDocs, and mdBook - [Configuration](https://sriram-pr.github.io/doc-scraper/reference/configuration/) and [CLI](https://sriram-pr.github.io/doc-scraper/reference/cli/) reference - [Detection benchmark](https://sriram-pr.github.io/doc-scraper/benchmark/) ## Contributing Contributions are welcome.
