List of production apps with MCP server support in 2026, what I've been testing and what's missing

Around 8-10 apps in the social/marketing space have shipped working MCP servers as of mid 2026. Buffer, Hootsuite, Later, Loomly, Sendible still don't have it. Been testing most of the shipped ones for a month, here's the honest breakdown. Vista Social has 35+ MCP tools and covers the widest surface (scheduling, analytics, inbox, team). Deepest integration by far. Downside is $120/mo entry which is steep for solo folks. Metricool ships around 10 MCP tools via ai.metricool.com/mcp, at $22/mo. Strong analytics, weaker on cross platform posting flow. SocialPilot at mcp.socialpilot.co/mcp is agency focused, works with Claude and ChatGPT out of the box, decent draft/approval flow. Outstand exposes 25 tools across 10 platforms via mcp.outstand.so/mcp. Blotato works with Claude Code specifically, starts $29/mo, 8 platforms, no built in analytics. On the smaller/newer side: PostFast has 11 platforms including Google Business Profile (nobody else keeps GBP now that Buffer dropped it), works with Claude, Claude Code, ChatGPT, n8n, Zapier and Make. Pricing is €10/mo which is the cheapest MCP-supporting one I found. Cons: analytics are basic vs Metricool, community is small since it's newer, no unified inbox. Postiz is open source and self hosted if you want full control, but you're running your own infra. OpenTweet is Twitter/X only with 12 tools, and Oktopost is a B2B specialist tied to CRM funnels. What's missing across the whole category: nobody has solved multi-client agency workspaces + MCP + fair pricing together. Vista Social has the workspaces but at $120/mo. SocialPilot has agency stuff but their MCP is thinner. The cheaper tools (PostFast, Metricool) skew toward solo/small team use. Also no MCP server has cracked long form YouTube uploads yet, everyone falls back to Shorts. For my case (running social for a few brands, mostly writing content in Claude anyway), the cheap MCP-first tools won since the workflow save mattered more than analytics depth. If I was doing enterprise reporting I'd go Vista or Metricool. Anyone found MCP servers I missed?? Curious what's actually being run in production vs demo-ware
