Olostep for AI agents
Olostep provides web scraping, crawling, search, and structured data extraction as an API. Developers and researchers use it to pull content from websites at scale without building their own crawler. 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 Olostep.
Scrape a single web page
Retrieve clean content from a specific page URL for use in a research summary.
Start a site crawl
Kick off a crawl of a website to map its pages before extracting structured data.
Check remaining credit balance
Look up the account's credit balance read-only before starting a large crawl job.
9 Olostep actions, graded by risk.
Every Olostep action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

Olostep in three steps.
- 01Your users connect OlostepThey add their Olostep api key on Arc0 Connect, under your brand. It goes straight into the vault.
- 02You set the rulesReads run, and writes like “map Website” can wait for the user to approve.
- 03Any agent can actYour agent calls Olostep through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('olostep', { read: 'allow', write: 'ask', // map_website destructive: 'deny', }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
How Olostep connects.
Users add their Olostep 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 Olostep 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 Olostep from any agent.

Olostep and Arc0, answered.
Can I use Olostep with Claude, ChatGPT or Cursor?
Yes. Connect Olostep 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 Olostep actions you allow.
How do users connect Olostep?
Users add their Olostep 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 Olostep actions can my agent take?
9 in total: 6 read, 3 write and 0 destructive, such as “map Website”. Your policies decide which of them each agent may call.
Can I make my agent read-only in Olostep?
Yes. Allow read actions and deny writes in the Olostep policy. Your agent can still look things up, and any write it attempts is blocked and logged.
Can my own backend call Olostep too?
Yes. The same Olostep connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug Olostep into your agent.
Your users connect Olostep once, under your brand. Your agent gets 9 actions behind your policies, with every call on the record.
