WHAT IT DOES

What monitor_add does on Yaver

AI agents use monitor_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
`url`	string	Yes
`name`	string	—
`method`	string	—	HTTP method, default GET
`interval`	string	—	Go duration, e.g. 60s, 5m

Parameters from the server's own tool schema.

RISK

Why monitor_add is rated Medium

This tool creates a new monitoring resource (registering a monitor), which is a reversible write operation. It does not execute code, delete data, or move money. Misuse could result in unwanted monitors being created or alerts being fired, but the blast radius is moderate.

RECOMMENDED RULE

The rule that runs monitor_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 monitor_add, this is the rule to start with:

monitor_add Rate-limited

monitor_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 monitor_add call is checked against it from then on.

How do I enforce a policy on monitor_add? +

Register the Yaver MCP server in PolicyLayer and add a rule for monitor_add: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Yaver. Nothing to install.

What risk level is monitor_add? +

monitor_add is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit monitor_add? +

How do I block monitor_add completely? +

Set action: deny in the PolicyLayer policy for monitor_add. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides monitor_add? +
