Social networking and community MCP servers let AI assistants post content, read feeds, manage communities, analyze engagement, and interact with social platforms. Instead of switching between apps or building custom integrations, you can wire social media capabilities directly into your AI workflow through the Model Context Protocol.

This review covers the social networking and community vertical — Twitter/X, Bluesky, LinkedIn, Reddit, Discord, Mastodon/Fediverse, YouTube, TikTok, and Hacker News. For communication platforms (Slack, Teams), see our Communication MCP review. For content creation tools, see our Content & Copywriting review.

The headline findings: Chinese social platforms exploded — xiaohongshu-mcp at 15,300+ stars is one of the highest-starred MCP servers in any category. Four major gaps filled since our initial review — Threads, Pinterest, Twitch chat, and Chinese platforms all now have MCP servers. Reddit grew substantially with reddit-mcp-buddy (795 stars) as the new leader. LinkedIn leadership changed — stickerdaniel’s server hit 3,100+ stars with 30+ tools. Cross-platform matured — Postiz (34,700+ stars) now has native MCP support (11 tools, per its own docs). ActivityPub grew its tool surface substantially, though we could not reverify a precise current total. This is now the deepest MCP category we’ve reviewed, with 80+ servers covering every major global social platform.

Category: Communication & Collaboration

Twitter / X

Server Stars Language License Tools
twitter-mcp 402 TypeScript 2

The most starred dedicated Twitter MCP server — enables posting tweets and searching Twitter through a clean TypeScript implementation. It remains the star leader for Twitter-specific servers. Correction (2026-08-16): star count updated to the current live figure (402), verified via GitHub.

crazyrabbitLTC/mcp-twitter-server (Most Tools)

Server Stars Language License Tools
mcp-twitter-server 25 TypeScript 53

The most feature-rich Twitter MCP server — 53 total tools combining standard Twitter API and enhanced research:

  • 33 Twitter API tools — post, delete, search tweets, analytics, user info, lists, likes, retweets, engagement
  • 20 SocialData.tools research tools — bypass typical API tier restrictions for deeper research
  • 5 workflow prompts — pre-built automation templates
  • 6 dynamic resources — real-time API documentation and status

Requires Twitter API credentials. SocialData.tools API key optional for enhanced research. The most complete Twitter MCP implementation by a wide margin.

adhikasp/mcp-twikit (No Official API Needed)

Server Stars Language License Tools
mcp-twikit 234 Python MIT 2

Uses the Twikit library to interact with Twitter without official API access — now at 234 stars, making it the second most-starred Twitter MCP server. Good for users who don’t want to pay for Twitter API tiers. Uses session-based authentication.

nirholas/XActions (Multi-Platform, Most Tools) — NEW

Server Stars Language License Tools
XActions 451 JavaScript Apache-2.0 140+

The most ambitious social MCP project — 140+ tools covering X/Twitter, Bluesky, Mastodon, and Threads. No API key required — uses browser extension + CLI + MCP architecture. A significant multi-platform entrant that blurs the line between Twitter-specific and cross-platform. Correction (2026-08-16): star count corrected from 228 to 451 (verified via GitHub); the “v3.1.0 / 58K+ lines of code” figures from the prior audit could not be reverified in the current README and have been removed rather than repeated unverified.

Infatoshi/x-mcp — NEW

Server Stars Language License Tools
x-mcp 51 TypeScript MIT 15

Created February 2026 — a clean 15-tool design covering the full Twitter API surface: post, read, engage, media, analytics, and bookmarks. Supports Claude Code, Codex CLI, and Cursor. The most modern Twitter-specific implementation.

Other Twitter/X Servers

  • rafaljanicki/x-twitter-mcp-server (30 stars) — Twitter API v2, rate limit handling, user/tweet/search/bookmarks
  • taazkareem/twitter-mcp-server (20 stars) — media upload support, MIT
  • lord-dubious/x-mcp — bridges LLMs to Twitter via Twikit
  • BioInfo/x-mcp-server — X API v2, posts and threads
  • Dishant27/twitter-mcp — CRUD operations via Twitter API

Correction (2026-08-16): a previously-listed entry, ryanmac/agent-twitter-client-mcp, has been removed from this review — GitHub has disabled the repository for a Terms of Service violation and it is no longer accessible.

Bluesky / AT Protocol

semioz/bluesky-mcp

Server Stars Language License Tools
bluesky-mcp 7 TypeScript ~6

A straightforward Bluesky MCP server. Supports:

  • Posting — create posts via AT Protocol
  • Engagement — like/unlike posts, repost
  • Timeline — read your feed
  • Profiles — view profile information

Requires BLUESKY_IDENTIFIER and BLUESKY_PASSWORD environment variables. Installable via Smithery. Correction (2026-08-16): the prior “featured in the official MCP server repository” claim came from the project’s own README and could not be independently verified — it does not appear in the modelcontextprotocol/servers reference README or the official MCP registry, so the claim has been removed rather than repeated unverified.

cameronrye/atproto-mcp (Full AT Protocol)

Server Stars Language License Tools
atproto-mcp 8 ~8

Broader AT Protocol access — not limited to Bluesky. Enables LLMs to interact with any AT Protocol-based social network through standardized MCP tools, resources, and prompts. Future-proof if the AT Protocol ecosystem grows beyond Bluesky.

brianellin/bsky-mcp-server

Server Stars Language License Tools
bsky-mcp-server 49 ~5

Search-focused Bluesky server — includes URL-to-AT-URI conversion, post search, people search, and time range filtering for fetching posts from timelines, lists, feeds, or profiles.

Other Bluesky Servers

  • morinokami/mcp-server-bluesky — general Bluesky interaction
  • berlinbra/BlueSky-MCP — user profiles and social graph data

LinkedIn

Server Stars Language License Tools
linkedin-mcp-server 3,100+ Python 30+

The new star leader for LinkedIn MCP — explosive growth to 3,100+ stars, now at release v4.22.0. Covers profiles, companies, jobs, messages, and profile editing. Very active development with frequent releases. Previously listed as a scraping option in our March review — it has since become the dominant LinkedIn MCP server. Correction (2026-08-16): star count corrected from 1,100+ to 3,100+ and version from v4.9.3 to v4.22.0 (both verified live on GitHub); the language was also corrected from TypeScript to Python — the prior audit had this wrong.

Other LinkedIn Servers

  • alinaqi/mcp-linkedin-server (54 stars) — 5 tools, browser automation via FastMCP
  • fredericbarthelet/linkedin-mcp-server — LinkedIn Community Management API, MCP OAuth 2.0 third-party auth flow
  • felipfr/linkedin-mcpserver — official LinkedIn API with OAuth 2.0
  • anysiteio/anysite-mcp-server — multi-platform (LinkedIn + Instagram + Reddit + Twitter) via Anysite API

Correction (2026-08-16): a previously-listed entry, adhikasp/mcp-linkedin, has been removed — the repository now returns a 404 on GitHub (deleted or renamed) and could not be reverified.

Reddit — EXPLOSION

Server Stars Language License Tools
reddit-mcp-buddy 795 TypeScript MIT 5

The new Reddit MCP leader at 795 stars — zero-setup anonymous mode (no API key needed for basic use), 3-tier authentication (10/60/100 requests per minute), in-memory caching up to 50MB. Tools: browse_subreddit, search_reddit, get_post_details, user_analysis, reddit_explain. NPM installable. The fastest-growing Reddit MCP server.

Correction (2026-08-16): the previous “v1.0.0… expanded from 30 to 65 tools in the March 2026 release” detail could not be reverified against the current README/release history and has been removed.

v-3/discordmcp

Server Stars Language License Tools
discordmcp 224 TypeScript MIT 2

Minimal but popular — only 2 tools (send-message, read-messages) but 224 stars. Proof that simple, focused servers can attract adoption.

hanweg/mcp-discord

Server Stars Language License Tools
mcp-discord 163 Python MIT 14

14 tools across 4 categories (server info, messages, channels, roles). Python-based with 25 commits. Solid mid-range option.

HardHeadHackerHead/discord-mcp

Server Stars Language License Tools

barryyip0625/mcp-discord

Server Stars Language License Tools

discord-mcp 35 Python 128

Grew from 10 to 35 stars. 128 operations across 28 categories including dedicated moderation. Uses a 3-tool discovery pattern (discord_discover, discord_get_schema, discord_execute).

Fediverse / Mastodon — MAJOR UPGRADE

cameronrye/activitypub-mcp

Server Stars Language License Tools
activitypub-mcp 17 TypeScript MIT 20+

Expanded from a small read-only server into a much broader tool surface — the current README (verified 2026-08-16) lists public read tools (discover-actor, fetch-timeline, get-post-thread, get-instance-info, search, discover-instances, and more), authenticated read tools (list-accounts, get-home-timeline, get-notifications, get-bookmarks, get-favourites, and more), and an opt-in write tool set (post, reply, delete, boost, favourite, bookmark, follow, mute, block, vote, media upload, and scheduled posts):

  • Full write capabilities — create posts, reply, boost, favorite, bookmark (was read-only)
  • Multi-account support with secure credential storage
  • Media upload, poll voting, post scheduling
  • Content export, audit logging, rate limiting, instance blocklist support

Works with Mastodon, Pleroma, Misskey, and any ActivityPub-compatible platform. This is architecturally significant — one server covers the entire federated network. Correction (2026-08-16): the previous “v1.1.0 — 53 Tools” figures could not be reverified — the latest release is v3.2.1 and the current README does not state a total tool count, so the precise “53” and the “21/28/4” category breakdown have been removed rather than repeated unverified.

Groupthink-dev/mastodon-blade-mcp — NEW

Server Stars Language License Tools
mastodon-blade-mcp Python MIT 45

“Security-first, token-efficient MCP server for Mastodon” — 45 tools (25 read, 20 write) across timelines, statuses, notifications, search, and social interactions. Created April 2026. Notable for its tool count rivaling the ActivityPub server.

YouTube — Leaders Emerged

Server Stars Language License Tools

The most comprehensive YouTube MCP server — 20+ command categories covering nearly all YouTube API resources: videos, playlists, captions, channels, comments, subscriptions, search, members, i18n, and channel banners. CLI + MCP server + AI agent in one package. Correction (2026-08-16): star count updated from 440 to 616; the prior “ranked 19th among all MCP servers” claim does not appear in the current README and no independent ranking source could be found, so it has been cut.

dannySubsense/youtube-mcp-server

Server Stars Language License Tools
youtube-mcp-server 12 Python 14

14 tools via YouTube Data API v3 — search, analyze, retrieve video/channel/playlist info. Includes technology freshness scoring. Feature-rich but low adoption at 12 stars.

erithwik/mcp-hn leads at 75 stars. Multiple implementations for fetching stories, discussions, and comments.

Chinese Social Platforms — EXPLOSION (Gap Filled)

This is the biggest story in this refresh. Chinese social platforms went from zero MCP servers to having one of the highest-starred MCP servers in any category.

xpzouying/xiaohongshu-mcp (15,300+ Stars — Breakout)

Server Stars Language License Tools
xiaohongshu-mcp 15,300 Go 11

iFurySt/RedNote-MCP

Server Stars Language License Tools

1,100 stars — auth management, keyword search, CLI init, note retrieval, comment access. Uses Playwright for browser automation.

Correction (2026-08-16): star count updated from 28,000+ to 34,700+ and license corrected from Apache-2.0 to AGPL-3.0 (both verified live on GitHub) — the prior license was wrong.

The gap list has shrunk dramatically since March:

  • No ThreadsFILLED (baguskto/threads-mcp, mikusnuz/meta-mcp)
  • No PinterestFILLED (collactivelabs/pinterest-mcp-server)
  • No Chinese platformsFILLED (xiaohongshu-mcp 15,300+ stars, RedNote 1,100, Douyin 1,200, WeChat, Weibo)
  • No Twitch chatFILLED (mtane0412/twitch-mcp-server 13 tools)
  • No community moderationPARTIALLY FILLED (SaseQ/discord-mcp moderation tools, facebook-mcp-server comment moderation)
  • No social listeningEMERGING (socialanalytics-mcp, mcp-social-listening)
  • No Snapchat consumer — ads-only integration exists, no Stories/messaging
  • No unified cross-platform analytics dashboard — analytics exist per-platform but no aggregator
  • No influencer management — no dedicated outreach, campaign tracking, or creator tools
  • No WhatsApp — despite being the world’s most-used messaging app

The Bottom Line

Rating: 5/5 — This is now the deepest and most complete MCP category we’ve reviewed. The transformation since March 2026 is remarkable:

Chinese social platforms exploded from zero to 15,300+ stars — xiaohongshu-mcp is one of the highest-starred MCP servers in any category. Four major gaps filled — Threads, Pinterest, Twitch chat, and Chinese platforms all now have working MCP servers. Reddit grew substantially with reddit-mcp-buddy hitting 795 stars. LinkedIn got a new leader at 3,100+ stars with 30+ tools. Cross-platform matured — Postiz (34,700+ stars) now has native MCP support (11 tools) for multi-platform scheduling. ActivityPub expanded its tool surface to full read/write/multi-account capability, though we could not reverify a precise current tool total.

The category now covers every major global social platform — Western (Twitter/X, LinkedIn, Reddit, Discord, YouTube, TikTok, Bluesky, Mastodon, Facebook, Threads, Pinterest, Twitch) and Eastern (Xiaohongshu, Douyin, WeChat, Weibo, Bilibili). With 80+ servers, this is an extraordinary level of ecosystem coverage. The only remaining gaps are Snapchat consumer features, unified cross-platform analytics, and dedicated influencer management tools.

Best for Twitter/X: nirholas/XActions (451 stars, 140+ tools, multi-platform) or EnesCinr/twitter-mcp (402 stars, simpler) Best for LinkedIn: stickerdaniel/linkedin-mcp-server (3,100+ stars, 30+ tools, v4.22.0) Best for Reddit: karanb192/reddit-mcp-buddy (795 stars, zero-setup) or Arindam200/reddit-mcp (298 stars, write support) Best for Discord: SaseQ/discord-mcp (452 stars, 60+ tools, Java) Best for Fediverse: cameronrye/activitypub-mcp (v3.2.1, full read/authenticated/write tool set) Best for YouTube: eat-pray-ai/yutu (616 stars, 20+ tools, full API) or kimtaeyoon83/mcp-server-youtube-transcript (582 stars, transcripts) Best for Chinese platforms: xpzouying/xiaohongshu-mcp (15,300+ stars) or runesleo/x-reader (953 stars, multi-platform reader) Best for cross-platform: Postiz (34,700+ stars, open source scheduler + MCP)
