WHAT IT DOES

What domain_ddns_start does on Yaver

AI agents invoke domain_ddns_start to trigger actions in Yaver. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

Parameter	Type	Required	Description
`domain`	string	Yes
`interval`	string	—	Check interval (default: 5m)
`provider`	string	—	DNS provider (default: cloudflare)

Parameters from the server's own tool schema.

RISK

Why domain_ddns_start is rated High

This tool executes an external service/daemon that modifies DNS records on Cloudflare—a critical infrastructure component. While DNS updates themselves are Write operations, the act of 'start' triggers an autonomous process whose side effects cannot be precisely predicted without knowing the current network state, existing DNS entries, and Cloudflare account configuration.

From the tool's definition The tool 'domain_ddns_start' starts a dynamic DNS updater that auto-updates Cloudflare DNS records when IP changes. This invokes and triggers an external operation (DDNS updater process) whose effects depend on network configuration and external service state.

RECOMMENDED RULE

The rule that runs domain_ddns_start 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_ddns_start, this is the rule to start with:

domain_ddns_start Rate-limited

domain_ddns_start stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

What parameters does domain_ddns_start accept? +

domain_ddns_start accepts 3 parameters: domain, interval, provider. Required: domain. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on domain_ddns_start? +

Register the Yaver MCP server in PolicyLayer and add a rule for domain_ddns_start: 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 domain_ddns_start? +

domain_ddns_start is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit domain_ddns_start? +

Yes. Add a rate_limit block to the domain_ddns_start rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block domain_ddns_start completely? +

Set action: deny in the PolicyLayer policy for domain_ddns_start. 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 domain_ddns_start? +
