Docs Fetch MCP Server

MCP server for fetching web page content with recursive exploration capability

What the server does

A Bun-based Model Context Protocol (MCP) server for fetching documentation pages and bounded documentation crawls.

• Fast static fetch path with axios
• Optional Puppeteer rendering for client-rendered or thin pages
• Markdown extraction with headings, lists, code blocks, tables, blockquotes, and links
• Real crawl depth semantics:
• depth: 1 returns only the root page
• depth: 2 includes direct child links

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

• depth — 1 returns only the root page
• sameOrigin — true rejects links whose origin differs from the normalized root URL
• includeLinks — false hides links in returned page objects but does not disable link discovery for crawling
• render — "never" uses only the HTTP fetch path
• url — string
• maxPages — number
• maxConcurrency — number
• timeoutMs — number
• perPageTimeoutMs — number
• pathPrefix — string
• contentLimit — number
• fetch_doc_content — The fetch_doc_content tool exposed by this server

Credentials and setup notes
