description: >-
  Name Whisper operates a public, anonymous remote MCP server at https://namewhisper.ai/mcp (streamable-http,
  session header mcp-session-id) exposing 44 tools over ENS names: search, valuation, market data, portfolio,
  and non-custodial transaction building for registration, renewal, Seaport listings/offers, records, NameWrapper
  and ERC-8004 agent identity. The server card at /.well-known/mcp.json, the MCP Registry listing
  ai.namewhisper/ens-tools (v1.2.0, 2026-07-31) and the live tools/list all agree on the endpoint and the tool
  count. tools/list answered anonymously with a full inputSchema (JSON Schema draft-07) and annotations
  (readOnlyHint / destructiveHint / idempotentHint) for every tool; the verbatim result is saved alongside as
  namewhisper-ai-mcp-tools-list.json and is the provider's machine-readable contract - no OpenAPI is published
  for the REST twins the docs say exist under /api/*.

  note: >-
    The README, the package.json (name namewhisper-mcp, version 1.2.0, bin namewhisper-mcp -> src/index.js,
    AGPL-3.0) and the Claude Desktop / Cursor / Claude Code snippets all advertise npx -y namewhisper-mcp, but
    registry.npmjs.org/namewhisper-mcp returned 404 {"error":"Not found"} and an npm search for "namewhisper"
    returned 0 results on 2026-09-19, so the advertised install fails. The stdio server is runnable only from a
    clone (node src/index.js). This is why deployment.mode is remote rather than both.

  note: >-
    read_only/destructive/idempotent are the server's own annotations counted from tools/list; free/transaction
    is the provider's classification from /.well-known/x402 and the server card. provision_agent_identity is
    annotated readOnlyHint true (it returns recommendations and unsigned transactions) but classified FREE, while
    every TRANSACTION tool returns unsigned calldata for the caller's wallet - the server never signs or broadcasts.

crosswalk_note: >-
  No tool crosswalk is emitted: there is no OpenAPI or GraphQL surface to bind the tools to. The docs state
  "All MCP tools have equivalent REST endpoints under /api/*" and the agents page says "120+ REST endpoints",
  but no REST reference or spec is published, robots.txt disallows /api/, and GET /api answers an x402 402
  discovery body. The tools/list result is therefore the only contract, and it is saved verbatim.
