The Best MCP Servers for Social Media (2026)

Breakreach was built around its MCP server rather than adding a connector to an older product. Setup is short: find Breakreach in Claude under Customize → Connectors or in ChatGPT under Settings → Plugins, click Connect, sign in, and connect your social accounts once through each network's official OAuth. From then on the assistant has 23 tools, including list_accounts, create_post (publish now, schedule, next free slot or draft, with per-network settings such as TikTok privacy or the Reddit subreddit), upload_media, get_next_slot, get_analytics, get_post_comments and reply_to_comment. Scheduling runs on Breakreach's servers, so "schedule this for Tuesday 6pm" still publishes after you close the laptop.

Where it pulls ahead is the layer under the protocol and the reach of a single connector. TikTok's photo API accepts only JPEG and WebP, so Breakreach converts every photo to JPEG before publishing. Subreddits that require a flair get it set by name. The same connector reads and replies to comments on Instagram, Facebook, Threads and X (YouTube is pending Google's approval), and handles DMs on Instagram, Facebook and X. Buffer's and Metricool's MCP servers have no comment tools at all.

The honest limits: it's a young product with real format gaps (no X threads, no LinkedIn Company Pages), no approval workflows, and no free plan. If you need governance or ads, look elsewhere. For someone who wants to plan, write, schedule, publish, measure and reply from a conversation without writing code, it's the most complete option here, and the $23/month Starter (billed yearly, 5 accounts) already includes the MCP server and the REST API.

Buffer opened its public API and an MCP server on May 27, 2026, and made both available on every plan, including Free. The server runs at mcp.buffer.com/mcp, and Buffer is listed in Claude's connector directory: Customize → Connectors → Browse connectors, search for Buffer, click Connect and approve. In ChatGPT, Buffer's docs add it as a custom app in developer mode, also with OAuth. The tools cover channels, posts (list, create, edit, delete), ideas, post templates and aggregated post metrics, plus raw GraphQL query and mutation tools for everything else.

For a small presence that's a strong offer: three channels, a queue your assistant can fill and read, and post metrics, for $0. The limits show up with volume. The Free plan holds 10 scheduled posts per channel and 3,000 API requests a month, shared between API keys and MCP connections. The MCP has no comment or DM tools, and Reddit, Telegram and Discord aren't on Buffer's network list.

Price per channel is the other thing to model. Essentials is $5 per channel per month billed yearly: 5 channels cost $25, against $23 for Breakreach's Starter with 5 accounts, and 15 channels cost $75, against $39 for Breakreach Pro. Pick Buffer if you already schedule there or want to try an assistant workflow without paying. Its AI Assistant is included on the Free plan too.

Zernio is what this category looks like when designed API-first for agents: one auth model and one request shape across 16 social networks, with a hosted MCP server at mcp.zernio.com/mcp exposing the same capabilities to assistants. Beyond publishing it covers analytics, comments, DMs and ads on 7 ad networks, which makes it one of the broadest API surfaces on this page.

The pricing model is the strategic weapon. Two accounts are free to prototype, accounts 3 to 10 cost $6 each, 11 to 100 cost $3, and every account past 100 costs $1. Zernio's own example puts 100 accounts at $318/month, and 200 accounts come to $418. If your product's unit of growth is the connected account, price this one first. Breakreach's developer plan ($5 per account, no free accounts) costs more at every count, and its accounts also work in a full scheduling app.

What it deliberately isn't: a product your non-technical client can log into. The dashboard is for connecting accounts and managing API keys, with no calendar or composer on offer. Zernio assumes you (or your agent) build that layer. For developers that's the point; for everyone else it's the reason to look at Breakreach, Buffer or Metricool instead.

Postiz is the open-source answer, and a capable one: a full scheduler with a dashboard, team features, and an MCP server that lists channels, schedules and publishes posts with per-platform settings, reads analytics, uploads media, and generates images and videos. It now has official connectors in both assistants' directories. In Claude, the directory version covers posting, scheduling and analytics, and Postiz points you to its custom MCP link for image and video generation. In ChatGPT, the official plugin carries the full toolset.

The honest cost of self-hosting is operational, and it stays invisible until you hit it. A social scheduler is only as good as its platform credentials: to publish to Instagram you need a Meta developer app that has passed App Review; to post public TikToks you need TikTok's content-posting audit; each network has its own version of this process, with lead times in weeks. Hosted providers absorb this with their own reviewed apps. Self-hosting Postiz puts all of it on your desk, plus the upkeep every time a network changes its API.

The pragmatic path: start on Postiz cloud ($29/month, or $23 billed yearly, for 5 channels, with credentials handled), and only self-host once data ownership or cost becomes decisive. If you have the infrastructure skills and the patience for platform reviews, nothing else here offers this much control.

Metricool earned its position from the analytics side: for years it has packed near-enterprise reporting (competitor benchmarks, ads performance, growth curves, best-time heatmaps) into an indie price. Its MCP makes that data conversational: an assistant can pull your top posts, compare months, and use real performance numbers to plan the next batch. Since September 10, 2026 the connector sits in both Claude's directory and ChatGPT's, and Metricool says it works on every plan, Free included, within your plan's limits.

As a publishing MCP it's solid on the basics: the assistant can view the planner, pick a recommended time, create and edit scheduled posts on 10 networks, and send posts for review. What's missing, per Metricool's own docs, is the engagement side (no comments, no inbox messages) and ads campaign management, though ads analytics are readable. There's no Reddit, Telegram or Discord. The natural fit is the data-driven marketer who spends more time in reports than in the composer, or Metricool as the analytics half next to a publishing-focused tool. The free plan makes trying that combination costless.

Ayrshare defined the social-media-API category years before AI agents existed, and that head start is its moat: the documentation covers edge cases newer competitors haven't met yet, and the API has a long production record. On June 4, 2026 it added an action MCP at api.ayrshare.com/mcp that lets agents publish, read history and analytics, and manage comments, DMs and profiles, plus a Claude Code plugin. A separate docs MCP only searches the API reference, so check which one you're adding.

The calculus is about money. At $149/month for a single profile, Ayrshare costs more at entry than any other tool on this list, and working with profiles through the MCP needs the $599 Business plan. For a funded company shipping a product where a publishing failure costs real revenue, that premium buys risk reduction. For an indie developer or a creator, most of the same features cost far less elsewhere, minus some maturity. Know which buyer you are.

Blotato started as an AI content tool for creators and now runs a hosted MCP server at mcp.blotato.com/mcp with 36 tools. Per its docs, the assistant can publish and schedule on all 9 networks, read analytics on 8 of them (not LinkedIn), and handle comments and DMs on Instagram and Facebook. Blotato lists Claude Code, Claude Desktop, Claude.ai, Cowork, Cursor, OpenAI Codex, Antigravity and Replit Agent as supported clients.

Its angle is the content itself: visual templates and AI image and video generation sit next to the scheduler, so an assistant can make the visual and post it in one flow. Blotato's own docs say it isn't in Claude's directory, so you add it by URL, and the 7-day trial leaves out API and MCP access. Pick it if you want AI-made visuals and 20 accounts for $29; pick Breakreach, Zernio or Postiz if you need Reddit, Telegram or wider engagement tools.
