Part of the Name Whisper — ENS Intelligence Layer server.
Free to start. No card required.
AI agents call get_valuation to retrieve information from Name Whisper — ENS Intelligence Layer without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though get_valuation only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Get a confidence-rated valuation for an ENS name based on comparable sales, entity recognition (Wikipedia/Wikidata), search interest, word frequency, and fame-scaled pricing. Returns estimated value range, background context on the name (person/place/brand/concept), comparable sales data, and a narrative explaining the valuation methodology. Essential for pricing decisions.. It is categorised as a Read tool in the Name Whisper — ENS Intelligence Layer MCP Server, which means it retrieves data without modifying state.
Register the Name Whisper — ENS Intelligence Layer MCP server in PolicyLayer and add a rule for get_valuation: 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 Name Whisper — ENS Intelligence Layer. Nothing to install.
get_valuation 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 get_valuation 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 get_valuation. 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.
get_valuation is provided by the Name Whisper — ENS Intelligence Layer MCP server (https://namewhisper.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
