Fibery for AI agents

Fibery is a work management platform where teams organize projects, entities, and workflows in a connected, customizable database instead of a fixed set of predefined views. 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.

01 · USE CASES

What agents do in Fibery.

01

Create a new entity

Create an entity, like a task or feature, once a team member defines the work to be tracked.

02

Count entities by type

Count entities of a given type to report how much work is in a particular status.

03

Confirm before deleting an entity

Require approval before deleting an entity, since it can remove linked history across the workspace.

02 · ACTIONS

26 Fibery actions, graded by risk.

Every Fibery action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

  3. 03Any agent can actYour agent calls Fibery 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('fibery', {
  read: 'allow',
  write: 'ask',        // update_entity
  destructive: 'deny',  // delete_file
})

04 · AUTH AND DATA

How Fibery connects.

Users add their Fibery 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 Fibery 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

Fibery and Arc0, answered.

Q01

Can I use Fibery with Claude, ChatGPT or Cursor?

Yes. Connect Fibery 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 Fibery actions you allow.

Q02

How do users connect Fibery?

Users add their Fibery 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 Fibery actions can my agent take?

26 in total: 8 read, 14 write and 4 destructive, such as “update Entity”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Fibery?

Yes. Actions like “delete File” 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 Fibery too?

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