  x-note: There is NO remote/hosted MCP endpoint. The WDK MCP Toolkit is a library that extends the official
    @modelcontextprotocol/sdk McpServer; developers run it locally over stdio with their own BIP-39 seed.
    A second, ready-made stdio server ships as the `wdk-mcp` binary inside @tetherto/wdk-cli. Because
    keys stay on the operator's machine by design, a hosted tools/list endpoint does not exist and was
    not probed for.
  status_note: Beta — docs record v1.0.0-beta.1; APIs may change between releases.

  human_confirmation: All write operations use MCP elicitations to require explicit user approval before
    broadcasting a transaction.
  annotations_published:
  - readOnlyHint
  - destructiveHint
  - idempotentHint

  extensible: Custom tools can be registered alongside built-ins using standard MCP SDK patterns.
  key_handling: Seed phrases stay local; `close()` wipes keys from memory; read and write tool sets are
    separable.
