Sanity for AI agents

Sanity is a headless CMS that stores structured content as documents, giving developers an API to build and manage content for websites and apps. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

What agents do in Sanity.

01

Fetch a document by its ID

Reads a specific content document, such as a blog post or product entry, before editing it.

02

Assign a default role to users

Grants project users a default role so they get the right level of access to content.

03

Delete a document only after confirmation

Removes an outdated document from the content dataset only once the request is confirmed.

02 · ACTIONS

21 Sanity actions, graded by risk.

Every Sanity action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

03 · HOW IT WORKS

Sanity in three steps.

  1. 01Your users connect SanityThey add their Sanity api key on Arc0 Connect, under your brand. It goes straight into the vault.
  2. 02You set the rulesReads run, writes like “create Prompt Post” can wait for the user, and “delete Document” can be denied outright.
  3. 03Any agent can actYour agent calls Sanity through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
POLICY.TS
await arc0.policies.set('sanity', {
  read: 'allow',
  write: 'ask',        // create_prompt_post
  destructive: 'deny',  // delete_document
})

# Claude Code: the same connection, one URL

04 · AUTH AND DATA

How Sanity connects.

Users add their Sanity api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

The same Sanity connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Sanity and Arc0, answered.

Q01

Can I use Sanity with Claude, ChatGPT or Cursor?

Yes. Connect Sanity to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Sanity actions you allow.

Q02

How do users connect Sanity?

Users add their Sanity api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

Q03

Which Sanity actions can my agent take?

21 in total: 13 read, 5 write and 3 destructive, such as “create Prompt Post”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Sanity?

Yes. Actions like “delete Document” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call Sanity too?

Yes. The same Sanity connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
