/**
 * MCP Server Middleware
 *
 * Creates an HTTP middleware for Harper's scope.server.http() that handles
 * MCP (Model Context Protocol) requests as direct JSON-RPC.
 *
 * Each knowledge base gets its own MCP endpoint at /mcp/<kbId>.
 * The kbId is extracted from the URL path, validated against the
 * KnowledgeBase table, and passed to all tools implicitly via the caller.
 *
 * Auth: Validates JWT Bearer tokens issued by the co-located OAuth 2.1
 * authorization server. Tokens are scoped to a specific KB via the
 * audience claim (aud = "{baseUrl}/mcp/{kbId}"). Unauthenticated
 * requests get read-only access.
