domains.list_tlds
List or search top-level domains (TLDs) with registry metadata. Filter by substring search, availability phase, TLD category, and paginate with limit and page. limit defaults to 100 when omitted. Each result includes the TLD suffix, type, availability phase, WHOIS server, domain counts when known...

What domains.list_tlds does on Vee3
AI agents call domains.list_tlds to retrieve information from Vee3 without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
page | object | — | Page number for paginated results. |
limit | object | — | Maximum number of TLDs to return. Defaults to 100 when omitted. |
search | object | — | Return TLDs whose suffix contains this substring. |
tld_type | object | — | Filter by TLD category: country-code, generic, generic-restricted, infrastructure, or sponsored. |
availability | object | — | Filter by registration phase: general-availability (normal public registration) or sunrise (early trademark-holder period). |

Why domains.list_tlds is rated Low
This tool only retrieves and queries publicly available TLD registry metadata without any side effects. It performs information lookup operations comparable to the sibling tool domains.whois and domains.lookup, which are standard read operations. There is no capability to modify, create, delete, or execute any operations.
From the tool's definition Tool description states 'List or search top-level domains (TLDs) with registry metadata' and retrieves information including 'TLD suffix, type, availability phase, WHOIS server, domain counts...
Attacks that exploit this kind of access
The rule that runs domains.list_tlds safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Vee3, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For domains.list_tlds, this is the rule to start with:
domains.list_tlds is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Vee3, apply this rule, and every domains.list_tlds call is checked against it from then on.
Questions about domains.list_tlds
List or search top-level domains (TLDs) with registry metadata. Filter by substring search, availability phase, TLD category, and paginate with limit and page. limit defaults to 100 when omitted. Each result includes the TLD suffix, type, availability phase, WHOIS server, domain counts when known, registry organization details, and created/changed timestamps. availability values: general-availability (open for normal registration) or sunrise (trademark sunrise period before general availability). Cost = 2 tokens. It is categorised as a Read tool in the Vee3 MCP Server, which means it retrieves data without modifying state.
domains.list_tlds accepts 5 parameters: page, limit, search, tld_type, availability. The full parameter table on this page comes from the server's own tool schema.
Register the Vee3 MCP server in PolicyLayer and add a rule for domains.list_tlds: 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 Vee3. Nothing to install.
domains.list_tlds is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the domains.list_tlds 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.
Set action: deny in the PolicyLayer policy for domains.list_tlds. 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.
domains.list_tlds is provided by the Vee3 MCP server (https://mcp.vee3.io/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
