Tavily for AI agents
Tavily is a search and extraction API for pulling current information from the web, used by agents and research tools that need fresh answers rather than a static index. 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 Tavily.
Search the web for current information
Run a search query and return ranked, relevant results for a research task.
Extract content from a page
Pull the readable text from a specific URL instead of scraping it by hand.
Check usage before a large crawl
Look up remaining Tavily usage before starting a website-wide crawl that could consume a lot of credits.
5 Tavily actions, graded by risk.
Every Tavily action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

- 02You set the rulesReads run, and writes like “tavily map website” can wait for the user to approve.
- 03Any agent can actYour agent calls Tavily through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('tavily', { read: 'allow', write: 'ask', // map destructive: 'deny', }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
How Tavily connects.
Users add their Tavily 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 Tavily connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →
- AUTH
- API key
- CREDENTIALS
- Per-tenant encrypted vault
- MODEL SEES
- Results only, never credentials
- AUDIT LOG
- Every call, on every plan
Use Tavily from any agent.

Tavily and Arc0, answered.
Can I use Tavily with Claude, ChatGPT or Cursor?
Yes. Connect Tavily 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 Tavily actions you allow.
How do users connect Tavily?
Users add their Tavily 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.
Which Tavily actions can my agent take?
5 in total: 4 read, 1 write and 0 destructive, such as “tavily map website”. Your policies decide which of them each agent may call.
Can I make my agent read-only in Tavily?
Yes. Allow read actions and deny writes in the Tavily policy. Your agent can still look things up, and any write it attempts is blocked and logged.
Can my own backend call Tavily too?
Yes. The same Tavily connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug Tavily into your agent.
Your users connect Tavily once, under your brand. Your agent gets 5 actions behind your policies, with every call on the record.
