  note: >-
    The served spec at https://mcp-server.metadata.io/openapi.json carries no servers[],
    no description, no contact, no licence and no tags, and describes only two health
    endpoints. This overlay adds the missing document-level metadata that is verifiable
    from Metadata's own published surface, and marks plainly that the product surface is
    the 141-tool MCP endpoint on the same host rather than anything in this REST document.
    It never mutates the original spec.

        Health endpoints for the Metadata (MetadataONE) MCP server. This OpenAPI describes
        infrastructure liveness only. Metadata's product surface is the Model Context Protocol
        endpoint at https://mcp-server.metadata.io/mcp, which exposes 141 tools for B2B paid
        media execution across LinkedIn, Meta, Google, Microsoft and Reddit. See
        https://metadata.io/developers/tools/ for the published tool catalog.
