Volume's MCP works with Claude, ChatGPT, Cursor, Claude Code and Codex. Your agent can search the Volume Library (TikTok and Instagram posts that beat their account's average, the formats behind them, and long-running Meta ads, by niche), use eight social tools for live data (ads on Meta, Google, LinkedIn or TikTok; any post's details; a competitor's recent posts; what's trending; comments and Reddit; creators; TikTok Shop; and one search across TikTok, Instagram, YouTube, Reddit, Pinterest and more), then build slideshows with your brand and schedule them to TikTok.

Pricing: Core ($29.99/month) and Pro ($69.99/month) include Library search (1,000 searches a day), the social tools (1,000 or 3,000 calls a month) and making and scheduling slideshows. Both start with a 3-day free trial, which includes 50 social tool calls.

Ahrefs' official MCP is remote only, uses its own MCP key, and draws on your plan's API units; it's on Lite ($129/month) and up. Semrush's official MCP (OAuth by default) gives SEO API data, Trends API data and read-only Projects data, using API units on qualifying plans.

HubSpot's official remote MCP reads contacts, companies, deals, tickets and marketing content (campaigns, landing pages, blog posts) and can create and update CRM records, with OAuth so agents see only what your permissions allow. It's available to all HubSpot accounts.

Meta hosts its own Ads MCP, which can report on campaigns and create and manage ads, campaigns and catalogs, with Facebook Login for Business. Klaviyo's official MCP reads and manages campaigns, flows, profiles and reports, remotely with OAuth.

PostHog's hosted MCP runs analytics queries and SQL and manages flags and experiments; connecting and calling it is free. Google Analytics has an open-source MCP in the googleanalytics GitHub organization that runs GA4 reports, funnels and realtime reports.

Canva's AI Connector lets agents search, create, edit and export designs, on every Canva account including free. Buffer's MCP creates and schedules posts and manages your queue, on every plan including free.

Zapier's MCP runs actions across 9,000+ apps on any Zapier plan (each call uses two tasks). Composio connects 1,500+ apps through one MCP URL, free for up to 100,000 tool calls a month.

We checked each server's own documentation on November 5, 2026 for who makes it, how you sign in, what an agent can do, and what it costs. We favored official servers over community ones. Volume is our product; the rest we don't sell.
