Why does MCP not include enterprise auth?

By design. The MCP protocol spec focuses on the tool interface contract and deliberately leaves governance concerns to the deployment layer, creating a gap every enterprise team must fill themselves.

Which MCP gateways exist in 2026?

Major options include Tyk, Solo.io AgentGateway, Portkey, Arka, and Cordon. None are the canonical standard and all are third-party add-ons with incompatible APIs.

What is an MCP gateway?

An MCP gateway sits between the agent client and MCP servers, adding authentication, rate limiting, audit logging, and access control that the base protocol does not provide.

MCP has no built-in auth, rate limiting, or audit logging so every enterprise team builds their own governance gateway

Q: Does MCP have built-in authentication?

No. MCP deliberately leaves out enterprise concerns including authentication, retries, routing, and auditing. Teams must add a gateway layer or build their own.

MCP deliberately leaves out enterprise concerns including authentication, retries, routing, and auditing. In production this means teams scatter API keys, have no audit trail, no per-agent quotas, and no session-scoped access control. A Gartner report in 2026 called this the missing enterprise layer. Dozens of startups launched MCP gateways (Tyk, Solo.io, Portkey, Arka) to fill the gap, and the agentic-community/mcp-gateway-registry repo hit 661 stars. MCP's own 2026 roadmap lists enterprise auth as a top priority not yet shipped.

Product Idea from this Signal

A web app that provides auth, rate limiting, and audit logging for MCP servers without teams having to build a gateway themselves

1.8k ▲

Every team deploying MCP servers has to hand-roll the same auth, rate limiting, and audit logging layer because MCP has no built-in controls. This creates duplicated infrastructure work and leaves AI agent pipelines without consistent access governance. A managed gateway sits in front of any MCP server and delivers OAuth/Entra auth, per-client rate limits, and an immutable audit trail out of the box.

Gap Assessment

UnderservedExisting solutions leave gaps

Multiple MCP gateway products exist (Tyk, Solo.io, Arka, Portkey, Cordon) but all are third-party add-ons with no standard API or protocol. Enterprise teams are stuck choosing between incompatible gateway vendors.
