Part of the Name Whisper MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call get_wallet_portfolio to retrieve information from Name Whisper 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_wallet_portfolio 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.

Get all ENS names owned by a wallet address. Returns each name with label, tags, expiry, registration date, and active listing/offer prices. Useful for portfolio analysis and wallet profiling. If you are authenticated via ERC-8128 and omit the wallet parameter, your own wallet is used automatically.. It is categorised as a Read tool in the Name Whisper MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for get_wallet_portfolio. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Name Whisper MCP server.

Yes. Add a rate_limit block to the get_wallet_portfolio rule in your Intercept 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 Intercept policy for get_wallet_portfolio. 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_wallet_portfolio is provided by the Name Whisper MCP server (namewhisper/ens-tools). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
