The Best Claude Plugins and Connectors for Marketing in 2026

Plugins vs connectors

• A plugin bundles skills, commands, agents and connector settings, so you add a whole way of working at once. You add plugins in Customize > Plugins, and they work in Cowork, Claude Code and, for skills and commands, in chat. Directory plugins show up on Pro, Max, Ultra, Team and Enterprise.
• A connector links Claude to one app or service through MCP. You add connectors in Customize > Connectors. They work on every plan, including Free, though the app behind one may need its own paid account.
• Adding a plugin doesn't connect anything. Anthropic's Marketing plugin, for example, comes set up for Canva, HubSpot, Ahrefs and others, and you still connect each one yourself.

The list

We list only what we found in Claude's marketplace on November 4, 2026. Anthropic doesn't publish a count; its sitemap has about 1,000 connector pages and 500 plugin pages.

Marketing (Anthropic)

Anthropic's own plugin for marketers, built for Cowork. It adds commands for the jobs that fill a marketer's week:

• /draft-content for blog posts, social posts, newsletters, landing pages, press releases and case studies
• /campaign-plan for a full campaign plan
• /brand-review to check a draft against your voice and style guide
• /competitive-brief, /performance-report, /seo-audit and /email-sequence

It comes set up for Slack, Gmail, Google Calendar, Canva, Figma, HubSpot, Amplitude, Notion, Ahrefs, Similarweb, Klaviyo and Supermetrics, and gets more useful with each one you connect. It doesn't post anywhere by itself. Sources: marketplace listing, source on GitHub.

Add it if you want one place to start. In the Claude app it's under Customize > Plugins. In Claude Code:

claude plugin marketplace add \
  anthropics/knowledge-work-plugins
claude plugin install \
  marketing@knowledge-work-plugins

Brand Voice (Tribe AI)

A partner plugin, verified by Anthropic, that reads your existing brand documents and call notes from connected tools such as Notion and Gong, writes brand guidelines from them, and holds every draft to those guidelines with its enforce-voice command. Source: marketplace listing.

Add it if a team writes for one company brand. For posts that sound like you as a person, Postel's voice profile is built from your own posts instead.

Postel

Postel is our product, so weigh this section accordingly. It's a connector in Claude's connector directory and a Claude Code plugin. It does the part the Marketing plugin leaves out: it looks up posts that did well in your niche, writes your version in the voice it learned from your own posts, and schedules it to X, LinkedIn, Bluesky and Mastodon after you approve. On LinkedIn it posts to your personal LinkedIn profile. On YouTube and TikTok, the agent saves the video post as a draft, and you choose the settings those networks ask for on every post, such as title and privacy, in Postel's editor before it's scheduled. TikTok posts go out as Only me from a private account until TikTok finishes reviewing Postel.

In Claude Code, the plugin adds the server and a writing skill:

/plugin marketplace add robinfaraj/postel-mcp
/plugin install postel@postel

Its listing in Anthropic's plugin directory is still in review, so in chat and Cowork you add Postel as a connector. It doesn't read comments, analytics or your feed.

Add it if you post as yourself on LinkedIn or X and want Claude's drafts to sound like you. Setup: Claude for social media.

Typefully

Typefully's connector, made by Typefully, drafts, schedules and publishes posts to X, LinkedIn, Substack, Threads, Bluesky and Mastodon, and nothing goes live until you confirm. Source: marketplace listing. See Postel vs Typefully.

Add it if you already write in Typefully.

Metricool

Metricool's connector schedules posts to Instagram, Facebook, X, LinkedIn, TikTok, YouTube, Pinterest, Bluesky, Threads and more, and reads analytics, best times to post and Meta and TikTok ad results. Metricool's free plan doesn't include LinkedIn or X. Sources: marketplace listing, pricing.

Add it if you want Claude to tell you how posts did, not only schedule them.

Canva

Canva has both a connector and a Claude Code plugin. Claude can search your designs, generate and fill templates, and export them; the plugin adds resizing for Facebook, Instagram and LinkedIn and checks against your brand kit. Sources: connector, plugin.

SEO, CRM, email and reporting

• Ahrefs and Semrush: keyword, backlink and competitor research; Ahrefs also tracks how often AI answers mention your brand. Ahrefs, Semrush.
• Similarweb: competitors' traffic and keywords. Listing.
• HubSpot: CRM records and campaign attribution. Listing.
• Klaviyo and Mailchimp: email reports, and Mailchimp can save a planned campaign. Klaviyo, Mailchimp.
• Supermetrics: data from Google Ads, Meta Ads, Google Analytics, LinkedIn, TikTok and 200+ other sources for performance reports. Listing.
• Socialinsider: social analytics and competitor benchmarks for Instagram, Facebook, TikTok, YouTube, LinkedIn and X. Listing.

Postiz

Postiz is a Claude Code plugin, not a chat connector: a command-line tool that schedules posts and reads analytics across 28+ networks. It's open source, so you can host it yourself. Source: marketplace listing. See Postel vs Postiz.

Not in Claude's marketplace

• Buffer and Hootsuite run their own MCP servers but have no listing in Claude's directory (checked November 4, 2026); add them with Customize > Connectors > Add custom connector and their server URL. Buffer's works on its free plan. Buffer MCP, Hootsuite MCP.
• LinkedIn. LinkedIn's own connector in Claude's directory, LinkedIn Hiring Pro, drafts and posts one free job listing; it doesn't write, schedule or publish posts to your feed.

How to pick

1. Start with the Marketing plugin. It's free on paid Claude plans and covers drafting, planning and audits.
2. Add connectors for the accounts you already pay for. A connector is only as useful as the account behind it.
3. For social posts, decide who writes. Typefully, Metricool and Buffer schedule what Claude writes. Postel also writes the post itself, in your voice.
4. Keep approvals on for anything that publishes. Claude asks before it runs a connector's tool unless you choose "Always allow". In Claude, Research can run connector tools without asking, so switch off Postel's schedule and publish tools before you use it.

Frequently asked questions

Updated Nov 4, 2026.

What is the best Claude plugin for marketing?

Anthropic's own Marketing plugin is the best place to start: it drafts content, plans campaigns, reviews copy against your brand and runs SEO audits, and it's free on paid Claude plans. Add connectors such as Canva, HubSpot or Ahrefs for the tools you use.

What's the difference between a Claude plugin and a connector?

A connector links Claude to one app through MCP. A plugin bundles skills, commands and connector settings into one install. Plugins work fully in Cowork and Claude Code, and their skills and commands work in chat; connectors work everywhere, including the free plan.

Is there a Claude plugin that posts to social media?

Yes. Postel, Typefully and Metricool are connectors in Claude's directory that schedule and publish posts, and Postiz is a Claude Code plugin. Postel is the one that also writes the post in your voice.

Do Claude plugins cost anything?

Anthropic's plugins are free, but the plugin directory only shows on paid Claude plans. Most connectors are free to add, but the service behind each one may need its own paid account.

Can I use these on the free Claude plan?

Connectors, yes: directory connectors on every plan, and one custom connector on Free. Directory plugins need Pro, Max, Ultra, Team or Enterprise.
