  Bound the delta-witness-mcp tool list (npm delta-witness-mcp 0.7.0 / MCP
  registry) to OpenAPI operationIds in openapi/delta-witness-openapi.json. The
  live MCP stdio schema was not introspected (local-stdio, payment-gated); tools
  mapped by name and by the published x402 discovery input schemas.

  note: >-
    MCP is local-stdio only. Tool inputSchemas are corroborated by the public
    /.well-known/x402 discovery document, which publishes JSON Schemas for the
    capture and guard resources.
