Top 5 MCP Gateways for UK Enterprise 2026

MCP gateways act as policy-enforcement layers between AI agents and Model Context Protocol servers, addressing optional protocol-level authorization and risks such as excessive tool permissions, token misuse, tool poisoning, prompt injection, and inadequate audit trails. The comparison identifies Azure API Management, Cloudflare MCP server portals, Kong AI Gateway, Solo.io agentgateway, and NeuralTrust TrustGate, the author’s product, as notable options for UK enterprises, evaluating identity support, per-tool controls, audit and SIEM integration, deployment models, and evidence of UK data locations. Azure is positioned for organisations using Azure and Entra, Cloudflare for unified access and security policies, Kong for existing Kong API-management users, Solo.io for Kubernetes-oriented teams seeking open-source software, and NeuralTrust for agent-focused security controls. UK guidance does not mandate MCP gateways but recommends comparable measures including unique agent identities, least privilege, immutable logs, sandboxing, and shutdown capability, while financial firms face third-party reporting requirements from March 2027. The summary cautions that UK data residency is not automatic and advises buyers to obtain written confirmation of data-plane, control-plane, log-storage, subprocessors, and audit-export locations before deployment.
