# Adding agent owners

Copy as Markdown[View as Markdown](/docs/development/guides/agents/ownership/owners.md)

***

**Added in** `eventcatalog@3.41.0`

Owners in EventCatalog are either **users** or **teams** and are optional. Assigning owners to an agent makes it clear who is responsible for keeping it up to date, responding to incidents, and approving model upgrades.

## Add owners using frontmatter[​](#add-owners-using-frontmatter "Direct link to Add owners using frontmatter")

Add the `id` of any user or team to the `owners` array in your agent's frontmatter:

/agents/FraudReviewAgent/index.mdx (example)

```
---
id: FraudReviewAgent
version: 0.0.1
owners:
  - dboyne      # a user id
  - full-stack  # a team id
---
```

Creating users and teams

EventCatalog gives you the ability to create users and teams. You can read the documentation to get started.

## Show owned agents on a team page[​](#show-owned-agents-on-a-team-page "Direct link to Show owned agents on a team page")

**Added in** `eventcatalog@3.41.0`

Teams and users gained an `ownedAgents` array alongside `ownedServices`. Add agent references to a team file to surface owned agents directly on the team's catalog page.

/teams/full-stack.mdx (example)

```
---
id: full-stack
name: Full Stack Team
ownedAgents:
  - id: FraudReviewAgent
    version: 0.0.1
  - id: OrderSupportAgent
ownedServices:
  - id: PaymentService
    version: 0.0.1
---
```

The same field is available on user files:

/users/dboyne.mdx (example)

```
---
id: dboyne
name: David Boyne
ownedAgents:
  - id: InventoryRebalancingAgent
---
```

If no `version` is provided, EventCatalog uses the latest version of the agent.
