1. Production Architecture: Multi-Tenant OAuth 2.1 Authorization & Scoped Tool Permissions for Production MCP Servers

export interface McpAuthContext {
  tenantId: string;
  userId: string;
  scopes: Set;
}

export function assertMcpScope(ctx: McpAuthContext, requiredScope: string): void {
  if (!ctx.scopes.has(requiredScope)) {
    throw new Error(`MCP Tool Forbidden: missing required scope '${requiredScope}' for tenant ${ctx.tenantId}`);
  }
}

2. Core Architectural Guarantees

  • Per-User OAuth 2.1 Token Delegation: Ensuring AI agents only query rows and execute actions permitted by the authenticated user's scopes.
  • Read-Only vs. Mutating Tool Separation: Enforcing explicit confirmation prompts on destructive or financial MCP tools.
  • Full JSON-RPC Audit Telemetry: Streaming every MCP tool invocation and response hash to SIEM/SOC2 audit logs.

3. Topical Category Hubs & Master Directory
