  "account": "When scaling MCP infrastructure to enterprise sizes, a few key factors dictate which gateway is the right choice. Token efficiency becomes critical as tool definitions consume vast amounts of context window space. Access control granularity also matters, as fine-grained permissions are required to separate customer facing agents from internal admin tools. Transport coverage must include stdio, HTTP, and streaming options like Server-Sent Events. Robust authentication with SSO and secrets management is essential, as are observability features for logging, cost attribution, and SIEM integration. Finally, deployment boundaries need to support self-hosted options within VPCs or air-gapped networks.\n\nBifrost, built by Maxim AI, stands out as the strongest overall choice for enterprise scale. By acting as both an MCP client and server in a single deployment, it simplifies integration across your existing systems. Bifrost connects directly to your filesystem, database, search, and custom APIs, automatically discovering tools and exposing them through a single gateway URL. Clients can connect without any configuration changes when you add a new server.\n\nPerformance-wise, Bifrost shows impressive efficiency, with a minimal 11µs overhead at 5,000 requests per second. It runs on a single t3.xlarge instance and scales well as traffic grows. Key capabilities include Code Mode, which reduces input token usage by up to 92.8% by exposing connected servers as lightweight stub files rather than carrying every tool definition in context. Bifrost also offers fine-grained tool filtering at the client, request, and virtual key levels, allowing for precise control over permissions. It supports enterprise identity-based governance through Okta, Microsoft Entra, Keycloak, Zitadel, Auth0, and Google Workspace, with SCIM 2.0 directory syncing.\n\nOverall, Bifrost's combination of performance, code efficiency, fine-grained access control, and enterprise-grade security makes it the best choice for scaling MCP gateways in large organizations.",
  "summary": "Connecting one MCP server to one agent is a five minute job. Connecting fifteen of them across four teams, each with its own credentials, its own tool catalogue and its own idea of what an agent should be allowed to touch, is an infrastructure problem. Tool definitions start to fill up the context window before the model has read your actual prompt, nobody can say which agent called which tool…",
