CMS platforms with an MCP server Claude can use in 2026
A CMS without an MCP server is a shop with no staff entrance, and these five give Claude a proper door.
A plain-text version of this site for AI assistants is at https://contengi.com/llms.txt, with the full product documentation in one file at https://contengi.com/llms-full.txt. Every page is also available as markdown by adding .md to its URL.
TL;DR
- The CMS platforms with an MCP server Claude can use in 2026 are Contengi, WordPress.com, Webflow, Sanity, and Contentful, and all five let Claude read and write content once you sign in.
- WordPress.com's MCP server works on every site, free or paid, and Jetpack-connected self-hosted sites use the same server without a Jetpack plan.
- Webflow lists its MCP server on every site plan, including the free Starter plan, with the full CMS from $25 a month billed yearly.
- Sanity and Contentful both run hosted MCP servers with OAuth and both have free plans, with Sanity's Growth plan at $15 per seat a month and Contentful Lite at $300 a month.
- Contengi adds a brand-aware blog layer on top, with more than 60 Claude tools and every edit held for your approval, from $50 a month.
A CMS without an MCP server is a shop with no staff entrance. Claude can still get the stock in, but only by climbing through the window, which in practice means you copying and pasting between a chat and an admin panel all afternoon.
Here are five platforms where Claude gets a proper door, with what each server can do and what the plans cost on each vendor's pricing page in October 2026. We built Contengi, so it goes first, and each of the others is a strong pick for something we don't do. The rest are in no specific order.
What does an MCP server add to a CMS?
An MCP server lets an AI app like Claude use your CMS directly: find a post, read it, draft a new one, change a field, and sometimes publish. MCP, the Model Context Protocol, is the open standard behind it, so one server works in Claude on the web, Claude Desktop, and Claude Code. If the acronym is new, start with what MCP is before you pick a platform.
The useful differences sit in three places: what the server can write, how it handles permissions, and whether anything goes live without a human click. Check all three before you connect anything.
CMS platforms with an MCP server at a glance
| Platform | Best for | Starting price |
|---|---|---|
| Contengi | On-brand blog writing and editing from Claude, on your existing site | From $50 a month, plus your Anthropic key |
| WordPress.com | Blogs and sites already on WordPress | Free, paid plans from $4 a month billed yearly |
| Webflow | Marketing sites where design and content sit together | Free Starter, CMS from $25 a month billed yearly |

| Contentful | Teams that need strict per-space permissions | Free, Lite $300 a month |
1. Contengi: best for when you want Claude to run your blog in your brand voice
Contengi is an agentic content platform with a CMS built in, and it publishes to WordPress, Shopify, Webflow, Framer, or a site built with Claude or v0 through one signed endpoint. The Claude connector gives Claude more than 60 tools: it reads your knowledge base and hard rules before it writes, edits a live post one section at a time with a diff you can revert, and researches with Search Console and GA4.
Nothing goes live on its own. Every draft and edit waits in Contengi until you publish it or ask Claude to. Contengi handles blog posts rather than page layouts or design, so if you want Claude building pages too, pair it with one of the platforms below. It's from $50 a month with no seats, it's in beta, and drafting through the connector runs on your own Claude plan.
Choose it if you want Claude writing and refreshing posts that sound like you, on the site you already have.
2. WordPress.com: best for when your site already runs on WordPress
WordPress.com has a built-in MCP server, and it works on every WordPress.com site, free or paid. Jetpack-connected self-hosted sites reach the same server, so a WordPress.org blog can join in too. Sign-in uses OAuth 2.1, and you choose full or read-only access when you approve Claude.
Claude can create, edit, and publish posts and pages, edit single blocks, and manage media. New posts start as drafts, and every write needs explicit confirmation. Paid plans start at $4 a month billed yearly, or $9 paid monthly.
Choose it if you want the cheapest route to letting Claude draft straight into a WordPress site.
3. Webflow: best for when you want Claude to touch design and content in one place
Webflow's MCP server reaches further into the site than a pure CMS can. Claude can manage CMS collections and items, create pages, read analytics, and build layouts, styles, and components. Each authorisation covers one workspace, and you can't create a brand new site project through MCP.
The MCP server is listed on every site plan, including the free Starter plan, which has a limited CMS of 50 items. The full Webflow CMS starts on Premium at $25 a month billed yearly.
Choose it if you manage a Webflow site and want Claude editing CMS items and building sections in the same chat.
4. Sanity: best for when you need custom content models and a developer in the loop
Sanity runs a hosted server at mcp.sanity.io with OAuth sign-in. Claude can query with GROQ, create and patch documents, publish, and even deploy schemas, and edits land in drafts or release versions rather than straight on published content. Most tools are standard API calls that don't use AI credits.
The free plan is $0 forever with up to 20 seats and 10,000 documents, and Growth costs $15 per seat a month. Sanity suits headless setups and sites built with Claude, where there's no admin panel to fall back on.
Choose it if your content has a shape a blog template can't hold, like products, docs, or multi-language pages.
5. Contentful: best for when permissions and governance come first
Contentful offers a remote server at mcp.contentful.com with OAuth 2.1, plus a local open-source one. The remote server checks both the user's own permissions and a per-space allow-list, and it covers entries, content types, assets, releases, and AI Actions, including publishing.
There's a free plan at $0 forever with 10 users and 100,000 API calls a month. The next step, Lite, costs $300 a month, so it's a jump for a small team.
Choose it if several people and environments share one content model and you want tight control over what Claude can touch.
How to connect a CMS to Claude safely this week
- Start read-only where the platform allows it, and ask Claude to find and summarise your five oldest posts.
- Write your rules down first, since Claude can only follow a tone of voice and banned-phrase list it can read.
- Turn on confirmations for every write, so drafts are free but publishing always needs a click from you.
- Test one real edit, like updating a stat in a live post, and check the diff before it goes out.
- Run the edited page through the AI slop cleaner and the AI bot view to check the copy reads like a person and crawlers can see it.
- Connect two servers at most, one for content and one for data, since every extra one adds tools Claude has to choose between.
For the data side of that pairing, here are the MCP servers worth connecting for content marketing.
Frequently asked questions
Which CMS platforms have an MCP server?
Contengi, WordPress.com, Webflow, Sanity, and Contentful all run MCP servers that Claude can use. Each one lets Claude read and write content after you sign in, with different limits on publishing.
Can Claude publish to my CMS through MCP?
Yes on Contengi, WordPress.com, Sanity, and Contentful, though the safeguards differ. WordPress.com creates drafts by default and asks for confirmation on every write, and Contengi never publishes unless you ask it to.
Is there a free CMS with an MCP server?
Yes. WordPress.com's server works on free sites, Webflow lists it on the free Starter plan, and Sanity and Contentful both have free plans.
Does self-hosted WordPress work with Claude?
Yes, through Jetpack. Jetpack-connected self-hosted sites use the WordPress.com MCP server without a Jetpack plan, and Contengi connects to self-hosted WordPress with an Application Password.
Do I need a developer to connect a CMS to Claude?
Not for WordPress.com or Contengi, which connect with a URL and a sign-in, and Webflow has setup guides for Claude Desktop and Claude Code. Sanity and Contentful are easy to connect, though neither of them are much use without someone who knows your content model.
