PageVitals for AI agents

PageVitals monitors website performance with synthetic tests, real-user data, and performance budgets. Web and engineering teams use it to catch slowdowns and regressions before they hurt users. 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.

PageVitals in three steps.

01Your users connect PageVitalsThey add their PageVitals api key on Arc0 Connect, under your brand. It goes straight into the vault.
02You set the rulesReads run, writes like “create Budget” can wait for the user, and “delete Budget” can be denied outright.
03Any agent can actYour agent calls PageVitals through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.

await arc0.policies.set('pagevitals', {
  read: 'allow',
  write: 'ask',        // create_budget
  destructive: 'deny',  // delete_budget
})

# Claude Code: the same connection, one URL
$ claude mcp add --transport http arc0 \

04 · AUTH AND DATA

How PageVitals connects.

Users add their PageVitals 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 PageVitals 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

07 · FAQ

PageVitals and Arc0, answered.

Q01

Can I use PageVitals with Claude, ChatGPT or Cursor?

Yes. Connect PageVitals 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 PageVitals actions you allow.

Q02

How do users connect PageVitals?

Users add their PageVitals 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 PageVitals actions can my agent take?

28 in total: 15 read, 9 write and 4 destructive, such as “create Budget”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in PageVitals?

Yes. Actions like “delete Budget” 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 PageVitals too?

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