Sanity MCP server: GROQ and mutations from Claude and ChatGPT

“Sanity MCP” names more than one thing. Sanity hosts its own MCP server at https://mcp.sanity.io for working on Sanity projects: content, schemas, datasets and releases. Community servers exist on GitHub. The Ryze AI server is a hosted connector that adds three Sanity tools next to the Ryze AI SEO publishing flow and its ad tools. This page documents the Ryze AI one and compares it with Sanity’s in section 06.

The names below come from the Ryze AI app source. Sanity is not connected in any test workspace yet, so the tool list was not seen live. Confirm it in your client after connecting.

A GROQ query, as the agent writes it

*[_type == "post" && !defined(slug.current)]{
  _id, title, _createdAt
} | order(_createdAt desc)

Posts with no slug, newest first. The type name post is whatever document type you picked when you connected Sanity.

A mutation, validated first

{
  "mutations": [
    { "patch": { "id": "drafts.<post id>", "set": { "seoDescription": "..." } } }
  ],
  "dryRun": true
}

The shape follows Sanity’s Mutate API. The drafts. prefix keeps the change as a draft; a plain id would publish it. Sanity’s own reference lists the mutation types and the dry run flag in the Mutate API docs. Ad and analytics tools on the same URL are documented on Google Ads MCP, Meta Ads MCP and Google Analytics MCP.

Ryze AI SEO publishes through its own pipeline, and the agent tools work on the same dataset. The rules differ, so read them before you write a prompt that changes documents.

Every answer comes from your own dataset, so no sample output is shown here. The full publishing workflow is described in the Ryze AI Sanity guide.

Step 1: connect Sanity in Ryze AI

1. 01At sanity.io/manage open the project and copy the Project ID.
2. 02Open API, then Tokens, click Add API token, choose Editor permissions and copy the token.
3. 03In Ryze AI open Integrations and click Connect on the Sanity card.
4. 04Enter the Project ID, the token, an optional dataset (default production) and the public Blog URL, then click Continue.
5. 05Pick the document type your blog posts use. The dataset needs at least one published post of that type.

Screens for each step are in the Ryze AI Sanity guide. A Viewer token is rejected.

Step 2: add the Ryze AI connector to your client

The connector URL is the same for every client:

https://connector.get-ryze.ai/mcp

Claude on the web or desktop

1. 01Go to Customize, Connectors.
2. 02Choose + Add, then Add custom connector. Enter Ryze AI as the name and https://connector.get-ryze.ai/mcp as the URL. Leave Authentication on a sign-in option, not No sign in.
3. 03Press Connect, sign in to Ryze AI, tick the workspace that holds Sanity and press Allow connection.
4. 04Start a new chat.

Any Claude plan works, and Free allows one custom connector. On Team and Enterprise an Owner adds the connector first and each member then clicks Connect.

ChatGPT

OpenAI documents custom MCP servers for ChatGPT Business and Enterprise/Edu on the web, where an admin or owner creates them, and read and fetch only on Pro. Open Plugins, choose the plus button, then Add custom MCP server, name it Ryze AI, enter the URL, pick OAuth, create it and sign in to Ryze AI. Plan rules for ChatGPT differ between OpenAI’s article and older guides, so check your plan in OpenAI’s help center. Write tools such as sanity__mutate need a plan with write actions.

Cursor

{ "mcpServers": {
  "ryze": { "url": "https://connector.get-ryze.ai/mcp" }
} }

Cursor runs OAuth the first time a tool is used. The Add to Cursor link on the developer page writes the same entry.

Claude tool cache

Claude keeps the tool list from the moment the connector is added. If you connect Sanity after the connector, remove the Ryze AI connector, add it again and start a new chat. ChatGPT also stores the tool list, so remove and re-add it there as well.

You can also connect Sanity from inside Claude or ChatGPT with a one-time connection link. The link is refused while a Sanity connection already exists in the workspace.

Fields Ryze AI needs when you connect:

Removing access

In Sanity, delete the token under API, Tokens in sanity.io/manage; Sanity says deletion revokes it immediately. In Ryze AI, open View on the Sanity card and use the trash icon. In Claude, open Customize, Connectors, Ryze AI and click Disconnect, which cuts off every workspace at once. A workspace holds one Sanity connection, tied to one project and dataset.

Three things called Sanity MCP

Source: Sanity MCP server docs, checked Nov 8, 2026. Sanity lists v2.46.0 from Nov 3, 2026 as the latest version, and says OAuth sessions expire after about 7 days and that custom validation rules are skipped when it runs over MCP.

Side by side

As published on Nov 8, 2026. Sanity adds tools often, so check its list before you decide.

Which to pick: if the work is building a Sanity project, changing schemas, managing datasets or releases, or generating images, Sanity’s own server covers far more. If the job is publishing SEO articles to a Sanity blog and checking the results next to Search Console or ad data in one chat, the Ryze AI connector fits. Both can run in the same client.

From Sanity’s technical limits and Query API pages, checked Nov 8, 2026. Sanity’s query reference sets no hard result size or request rate beyond these.

The first nine rows are Ryze AI and Sanity API behavior from the sources above; the last row is documented for Sanity’s own server. Exact error text was not seen live. More answers are in the integrations FAQ.
