Jigsawstack for AI agents

JigsawStack offers a suite of small AI models for tasks like OCR, sentiment analysis, translation, and web search, built into scalable infrastructure. 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.

  2. 02You set the rulesReads run, and writes like “create Prompt” can wait for the user to approve.
  3. 03Any agent can actYour agent calls Jigsawstack 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('jigsawstack', {
  read: 'allow',
  write: 'ask',        // create_prompt

})

04 · AUTH AND DATA

How Jigsawstack connects.

Users add their Jigsawstack 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 Jigsawstack 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

Jigsawstack and Arc0, answered.

Q01

Can I use Jigsawstack with Claude, ChatGPT or Cursor?

Yes. Connect Jigsawstack 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 Jigsawstack actions you allow.

Q02

How do users connect Jigsawstack?

Users add their Jigsawstack 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 Jigsawstack actions can my agent take?

23 in total: 13 read, 10 write and 0 destructive, such as “create Prompt”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in Jigsawstack?

Yes. Allow read actions and deny writes in the Jigsawstack policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call Jigsawstack too?

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