MCP Gateway

An enterprise MCP security checklist covering authentication modes, tool filtering, least privilege, approval gating and audit logging.

An MCP gateway is a centralized layer between AI agents and the MCP servers they call, exposing every connected tool through one endpoint. This guide covers the four roles a gateway plays, how it differs from an MCP server and a proxy, the deny-by-default access model, and when to adopt one.

An explanation of what an MCP gateway is and how it centralizes tool discovery, access control and execution for every AI agent.

TL;DR * Connecting 16 MCP servers to one agent puts 508 tool definitions into the model's context on every request, which consumed 75.1 million input tokens across a 65-query benchmark run. * MCP tool calling degrades as tool count grows because tool definitions are re-sent on

How to audit every AI agent tool call at the MCP gateway, covering what to capture and how audit logs differ from request logs.

TL;DR * An MCP gateway for Claude Code sits between Claude Code and your MCP servers and manages tool discovery, routing, authentication, and access control from one endpoint. * Bifrost ranks first for teams: it aggregates MCP servers behind one /mcp endpoint, scopes tools per virtual key, supports six MCP auth
