IAM Roles and Permissions

MeshAgent IAM controls access to project resources. It answers four questions:

Who is requesting access: a user, group, agent, service account, or userset.
What they are accessing: a project, room, repository, feed, secret, service account, or other project resource.
Which role they have on that resource.
Which room API scope a participant token carries after access is granted.

Use the smallest role or scope that lets the subject do its job.

Principals

Principal type	Description
`user`	A human project member.
`group`	A group of users. Group access applies through the group’s members.
`agent`	A managed agent principal.
`service_account`	A non-human identity used by services, jobs, API keys, and automation.
`userset`	A reference to another resource relation, such as all project members.

Resources

Resource type	Description
`project`	The top-level project boundary. Project roles can grant project-wide create, inventory, manage, billing, LLM proxy, and group-management access.
`room`	A room and its room-scoped APIs.
`agent`	A managed agent resource. Managed agent resource policies are not set through the generic IAM policy API; agent run-as and project agent roles control this surface.
`group`	A group and its membership.
`repository`	A project image repository.
`feed`	A feed and its publish/subscribe operations.
`secret`	A user secret that can be proxied to a service account.
`service_account`	A service account and the credentials or run-as permissions attached to it.

Project Roles

Project roles apply at the project level. owner is assigned to the project owner. admin inherits owner-level administrative capabilities. developer inherits a focused operational subset. Direct, narrower roles can also be granted independently.

Room API Scope Permissions

Room API scopes are embedded in participant tokens. They are not project roles. They control what a connected participant can call inside a room. If a grant object is absent, that API surface is denied. When a grant object exists, None in an allowlist generally means unrestricted access within that grant, and a boolean set to false disables that operation.

Managing IAM

Use MeshAgent Studio for day-to-day member management. Use the CLI or SDKs when provisioning access from automation.

meshagent iam policy --project-id <project-id> --resource-type room --resource-id <room-id>
meshagent iam grant --project-id <project-id> --resource-type room --resource-id <room-id> \
  --subject-type user --subject-id <user-id> --role viewer
meshagent iam revoke --project-id <project-id> --resource-type room --resource-id <room-id> \
  --subject-type user --subject-id <user-id> --role viewer
