Every entry below is confirmed against the vendor's own docs or an official launch announcement. A few servers marketers assume exist (a standalone Slack MCP server, Mailchimp, Airtable, Asana) returned no primary source, so they're flagged at the end instead of padding the list.
Content, docs, and collaboration
- Notion: official remote MCP server. Search, read, and create or update pages and databases (including a content calendar) after you authorize access.
- Google Drive, Gmail, Google Calendar, Microsoft 365: shipped as first-party "prebuilt integrations" inside Claude, ready after authentication, no separate setup.
- Slack: one of Anthropic's first-party Claude connectors. A standalone Slack-hosted MCP server couldn't be verified, so use the Claude connector instead.
Design and creative
- Figma Dev Mode MCP server: official, in beta. Pulls live component and layout data to turn a design into code, or a webpage back into editable layers.
- Canva: two different things. Canva is a launch partner app inside ChatGPT (the marketer-facing feature); its developer MCP server is a separate tool for building integrations.
CRM, sales, and e-commerce
- HubSpot MCP server: official. Read and write access to contacts, deals, and tickets, plus (for marketers) campaigns, landing pages, and blog posts, though the marketing content is read-only.
- Shopify MCP: official, two servers: one for catalog and checkout (an AI shopping agent), one for order tracking and returns.
Analytics
- Google Analytics MCP server: official, published by Google's GA engineering team, still labeled experimental. Pulls account and property data and runs GA4 reports conversationally.
Social and scheduling
- X: launched its own MCP server in June 2026 (per trade press) to open its platform to AI tools.
- Postey: MCP server for drafting, scheduling, and publishing across eight platforms directly from a Claude or ChatGPT chat, without leaving the chat.
- Buffer, Metricool: both confirmed shipping their own MCP servers as of 2026, joining a growing list of schedulers with agent access.
The universal-bridge option
- Zapier MCP: not a single-app integration but a meta-layer connecting roughly 9,000 apps and 30,000 actions through one setup, no code required.
Once connected, a community connector has the same capabilities and access as any connector you grant.
Source: Claude's connector directory documentation, which separates first-party, vendor-maintained MCP servers from community-built ones that are screened but not deeply reviewed. That matters more for account security than which logo is on a list. Check who built and maintains a connector before granting it access.
Not confirmed: don't treat these as live
Mailchimp's current developer docs describe only its standard Marketing API, with no MCP mention. A standalone Airtable MCP server, dedicated Asana MCP documentation, and Hootsuite MCP support couldn't be verified through primary sources. Several likely exist or are in progress. Check the vendor's own docs before building a workflow around any of them.
The useful takeaway isn't the length of this list. It's the split between vendor-maintained servers, which stay supported, and community-built ones, which carry real access with less review. Start with the first-party servers, and if scheduling is what you're connecting, Postey is the one built for it.
