WHAT IT DOES

What domain_add does on Yaver

AI agents use domain_add to create or update resources in Yaver, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Yaver environment.

Parameter	Type	Required	Description
`path`	string	—	Path prefix (default: /)
`domain`	string	Yes
`target`	string	Yes	App name or port

Parameters from the server's own tool schema.

RISK

Why domain_add is rated Medium

This tool creates or registers a new domain routing entry, which modifies application configuration persistibly. It is categorized as Write (creates/modifies data reversibly) rather than Execute because it configures infrastructure rather than triggering runtime operations.

From the tool's definition Tool name 'domain_add' and description 'Add domain routing (map domain to an app or port)' indicate creation of a new domain mapping configuration.

RECOMMENDED RULE

The rule that runs domain_add safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Yaver, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For domain_add, this is the rule to start with:

domain_add Rate-limited

domain_add stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Yaver, apply this rule, and every domain_add call is checked against it from then on.
