Servers to run behind it

mcp-hub is server-agnostic: it serves any stdio MCP server whose entry fits Claude Code's mcpServers format, which is most of them, plus remote upstreams over Streamable HTTP. Nothing on this page is required — it is a starting point for a config file.

The nineteen below are built and maintained alongside the hub. Their documentation carries the hub entry you need, their tool filters line up with the hub's own allowTools / denyTools, and each of them speaks both protocol revisions, so the elicitation the hub forwards reaches a person rather than stopping at a server that only knows the older one.

Server	npm	What it reaches
audiobookshelf-mcp	audiobookshelf-mcp	Audiobookshelf — libraries, listening progress, collections and playlists
caldav-mcp	@ni-c/caldav-mcp	CalDAV — events, tasks and journal entries on any server that speaks it
calibreweb-mcp	calibreweb-mcp	Calibre-Web — read-only library access through the OPDS feed
carddav-mcp	@ni-c/carddav-mcp	CardDAV — contacts, groups and photos on any server that speaks it
freshrss-mcp	@ni-c/freshrss-mcp	FreshRSS — feeds, categories and articles as plain text, not stream ids
google-search-console-mcp	@ni-c/google-search-console-mcp	Google Search Console — properties, sitemaps, search analytics, URL inspection
healthchecks-mcp	healthchecks-mcp	Healthchecks — cron and uptime checks, and why one failed
hetzner-dns-mcp	hetzner-dns-mcp	Hetzner Cloud DNS — zones, record sets and BIND import/export
imap-mcp	@ni-c/imap-mcp	IMAP mailboxes — read, search, organise and draft mail; it cannot send
linkwarden-mcp	linkwarden-mcp	Linkwarden — bookmarks, collections and the article text it preserved
mealie-mcp	@ni-c/mealie-mcp	Mealie — recipes, meal plans, shopping lists and cookbooks
ntfy-mcp	@ni-c/ntfy-mcp	ntfy — publish and update notifications, manage users and topic access
opengist-mcp	opengist-mcp	Opengist — gists, revisions, commit history and raw files
osm-mcp	osm-mcp	OpenStreetMap — geocoding, routing, isochrones and POI search
rustpad-mcp	rustpad-mcp	Rustpad — collaborative pads edited through real OT, not overwrites
smtp-mcp	@ni-c/smtp-mcp	SMTP — sends mail, behind a recipient allowlist and a human confirmation
wg-easy-mcp	wg-easy-mcp	wg-easy v15+ — the full WireGuard client lifecycle
wikijs-mcp	@ni-c/wikijs-mcp	Wiki.js — search, read and edit pages, plus assets, users and groups
woodpecker-ci-mcp	@ni-c/woodpecker-ci-mcp	Woodpecker CI — repositories, pipelines, logs, secrets and crons

Adding one

Every entry is the one you already have in Claude Code, dropped into the hub's /config/mcp.json:

{
  "mcpServers": {
    "wikijs": {
      "command": "npx",
      "args": ["-y", "@ni-c/wikijs-mcp"],
      "env": {
        "WIKIJS_URL": "https://wiki.example.com",
        "WIKIJS_TOKEN": "…"
      },
      "denyTools": ["delete_*"]
    }
  }
}

It is then reachable at https://your-host/wikijs, and through the /hub aggregate alongside every other server. See Configuration for the fields the hub adds on top of Claude Code's, and Connecting clients for the client end.
