Everhour for AI agents

Everhour is time tracking and expense management software with budgeting, resource planning, and reporting for project teams that bill clients based on hours worked. 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.

04 · AUTH AND DATA

How Everhour connects.

Users add their Everhour 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 Everhour 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

07 · FAQ

Everhour and Arc0, answered.

Q01

Can I use Everhour with Claude, ChatGPT or Cursor?

Yes. Connect Everhour 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 Everhour actions you allow.

Q02

How do users connect Everhour?

Users add their Everhour 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 Everhour actions can my agent take?

38 in total: 17 read, 16 write and 5 destructive, such as “create Webhook”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Everhour?

Yes. Actions like “delete Webhook” 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 Everhour too?

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