  This crosswalk exists to record a DIVERGENCE, not an overlap. EHRbase has both a
  published OpenAPI (63 operations) and a live remote MCP endpoint, and they share
  nothing: the MCP server is the WordPress Abilities adapter on the marketing site,
  and the OpenAPI is the openEHR clinical data repository each customer self-hosts.
  Coverage is genuinely zero. Nothing here is name-matched or semantically guessed.

      tools/list returns 401 without a bearer token. Whatever the WordPress MCP server
      exposes, it is site-content abilities (wp-abilities/v1) and has no counterpart in
      the openEHR REST contract.
