gomddoc MCP sunucusu

Gomddoc

A production-ready HTTP server and static site generator for Markdown documentation, with content negotiation, full-text search, SEO output and a built-in MCP server.

Status

Released and in use: v0.5.1 (2026-11-05) is on GitHub Releases, the Homebrew tap (monolithiclab/tap) and ghcr.io/monolithiclab/gomddoc, and it publishes Monolithic Lab's own sites. Pre-1.0: configuration keys can still change between minor versions (since v0.1.2 an unknown key in .gomddoc/config.yml is a load error, so check a site with gomddoc doctor before bumping a pinned version). Open bugs and the ranked backlog are in ROADMAP.md.

Features

• Universal Content Serving: Renders Markdown to HTML inside a theme; serves HTML, CSS, JS, images and every other file type with its detected MIME type
• Content Negotiation: Accept header support; Accept: text/markdown returns the raw Markdown source, an unsatisfiable Accept gets 406
• Clean URLs: .md is stripped from URLs by default (/guide serves the page for guide.md); links between pages written as guide.md point at the clean URL
• Markdown URLs: every page's .md URL (/guide.md) serves its Markdown with generated frontmatter, in serve and in static builds, and each HTML page links it as rel="alternate"
• llms.txt: /llms.txt indexes the site for AI agents from the navigation, each page linked by its Markdown URL
• Git-Native Content: Serve a local directory or a git+https:// / git+ssh:// repository URL (in-memory or on-disk clone)
• Static Site Generation: gomddoc build writes a static site with clean-URL directories, 404.html, sitemap, feed and redirect stubs
• Full-Text Search: TF-IDF inverted index built at startup, tag: filter syntax, GET /api/search, and a Ctrl+K search dialog in every theme
• SEO: Canonical URLs, sitemap.xml, robots.txt, Atom feed.xml, Open Graph and Twitter tags, JSON-LD, per-page robots, redirect_from and rel="prev/next", enabled by setting a domain
• Tags: Frontmatter tags rendered as chips, /tags/ and /tags/{tag} pages, a see-also section and /api/tags
• Internationalization: BCP 47 language directories (fr-FR/) served under /{lang}/, translated UI strings, a language switcher and hreflang tags
• MCP Server: gomddoc mcp (stdio) and /_mcp/ (Streamable HTTP) expose read-only search, page, section and navigation tools to AI agents; every stable release is listed in the MCP Registry as io.github.monolithiclab/gomddoc, running the container image
• Themes: One bundled theme (default) plus seven more in gomddoc-themes; feature toggles and CSS variables in config
• Review Annotations: Select text on a rendered page, attach a note, and copy every note of the page as Markdown naming the source file, ready to paste into an LLM harness; notes stay in the browser's localStorage
• Self-Documenting: gomddoc help, gomddoc info, gomddoc schema and gomddoc doctor read the embedded guide, list every setting, print the config JSON Schema and check a site for problems
• Secure Defaults: Path jail, hidden-file and exclude blocking (404), GET/HEAD-only content routes, security headers, optional htpasswd Basic Auth
• Operations: Graceful shutdown, configurable timeouts, gzip, ETags, Prometheus metrics, health endpoints, optional pprof, and a separate admin listener

Install

# Install script (Linux / macOS, amd64 / arm64): checksum-verified, cosign-verified when cosign is installed
curl -fsSL https://raw.githubusercontent.com/monolithiclab/gomddoc/main/scripts/install.sh | sh

# Homebrew (macOS / Linux)
brew install monolithiclab/tap/gomddoc

# Go toolchain
go install github.com/monolithiclab/gomddoc/cmd/gomddoc@latest

# Docker (multi-arch image on GitHub Container Registry)
docker run --rm -p 8080:8080 -v "$PWD:/site" ghcr.io/monolithiclab/gomddoc serve /site

Release archives carry an SPDX SBOM each and a Sigstore-signed SHA256SUMS; the Quick Start explains the install script's options and how to verify a release by hand.

Use

gomddoc serve ./docs                       # production server on :8080 (also git+https:// and git+ssh:// URLs)
gomddoc preview ./docs                     # dev mode, first free port from 8080, opens the browser
gomddoc build ./docs -d docs.example.com   # static site into build/site
gomddoc doctor ./docs                      # every configuration and content problem, with fixes
gomddoc help                               # the user guide, embedded in the binary

Development

Requirements: Go (the exact toolchain is pinned by go.mod's toolchain line and fetched automatically) and Make. Lint and benchmark tools are pinned in tools/go.mod; nothing needs installing globally.

make help   # every command
make ci     # the gate CI runs: golangci-lint, govulncheck, go mod tidy -diff, action/image pin checks,
            # then tests with -race and 87% minimum coverage (needs network for govulncheck)
make run    # serve ./testsite locally

Contributions: branch, make lint-fix, make ci, then a pull request. Coverage stays at 87% or above.
