TinyFish for AI agents

TinyFish automates web research and browsing through live browser sessions, used by teams that need an agent to search, extract, and act on web content at scale. 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 TinyFish.

01

Search the web for a topic

Run a live search and return results relevant to a research task.

02

Fetch content from a set of URLs

Pull the content of specific pages as a read-only extraction step.

03

Confirm before terminating a browser session

Check with the user before ending an active browser session, since in-progress work would be lost.

02 · ACTIONS

23 TinyFish actions, graded by risk.

  2. 02You set the rulesReads run, writes like “create Profile” can wait for the user, and “delete Profile” can be denied outright.
  3. 03Any agent can actYour agent calls TinyFish 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('tinyfish', {
  read: 'allow',
  write: 'ask',        // create_profile
  destructive: 'deny',  // delete_profile

04 · AUTH AND DATA

How TinyFish connects.

Users add their TinyFish 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 TinyFish 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

TinyFish and Arc0, answered.

Q01

Can I use TinyFish with Claude, ChatGPT or Cursor?

Yes. Connect TinyFish 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 TinyFish actions you allow.

Q02

How do users connect TinyFish?

Users add their TinyFish 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 TinyFish actions can my agent take?

23 in total: 11 read, 7 write and 5 destructive, such as “create Profile”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in TinyFish?

Yes. Actions like “delete Profile” 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 TinyFish too?

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