Which are the best MCP gateways for UK enterprise in 2026?
Five stand out for a UK security team: Kong, Azure API Management, Cloudflare, Solo.io's agentgateway and NeuralTrust's TrustGate, which is our own product and is labelled as such. We compared them on identity, tool-level control, audit, deployment options and documented UK locations, using pages reviewed on 1 October 2026.
An MCP gateway sits between AI agents and the MCP servers they call, so it is where a UK enterprise can enforce who uses which tool and prove it afterwards.
TL;DR: Key Takeaways
- Authorisation is optional in the protocol. The MCP specification dated 28 July 2026 treats authorisation as optional, so enforcement has to be added around the server (MCP specification, 2026).
- UK guidance already points at gateway-style controls. The NCSC's interim agentic AI guidance of 20 August 2026 sets out seven considerations, including deny-by-default sandboxing, unique agent credentials and emergency shutdown (NCSC, 2026).
- Real incidents involve MCP servers. A logic flaw in Asana's MCP feature exposed data across about 1,000 customers between 1 May and 4 June 2025 (BleepingComputer, 2025).
- Financial firms have a date. FCA policy statement PS26/2 takes effect on 18 March 2027 and expects a register of material third-party arrangements (FCA, 2026).
- Legislation is still moving. The Cyber Security and Resilience Bill finished Lords committee stage on 7 September 2026, and report stage had not been scheduled (UK Parliament, 2026).
At a glance: five MCP gateways for UK enterprise
The order below is alphabetical, not a ranking.
| Gateway | Deployment | UK location evidence (1 Oct 2026) | Strongest when |
|---|---|---|---|
| Azure API Management | Azure cloud, self-hosted gateway option | UK South and UK West listed; UK South v2 had temporary capacity limits | You already run on Azure and Entra |
| Cloudflare MCP server portals | Cloudflare network | UK-only decryption region via Regional Services; portal log boundary not verified | You want one policy layer for users and agents |
| Kong AI Gateway | Self-hosted or Konnect | Dedicated Cloud Gateways can run in London; Konnect geographies listed exclude the UK | You run Kong for APIs today |
| NeuralTrust TrustGate (our product) | SaaS, hybrid, on-premises | Not stated on the pages reviewed; confirm with NeuralTrust | Agent security is the main requirement |
| Solo.io agentgateway | Open source plus Solo Enterprise | No UK region found | You run Kubernetes and want open source |

What is an MCP gateway, and why do UK enterprises need one?
An MCP gateway is a proxy that brokers every call between agents and MCP servers, applying authentication, per-tool permissions, logging and policy. The need is practical. According to the OWASP MCP Top 10 (2025, beta), the top risks include token mismanagement, scope creep, tool poisoning, shadow MCP servers and missing audit, while the specification leaves authorisation optional.
Supply-chain incidents show the exposure. According to Dark Reading (2025), a malicious npm package called postmark-mcp added a hidden BCC to outgoing email and was downloaded by about 1,500 organisations. A gateway with an approved-server catalogue limits that kind of drift.
How we compared
We compared each gateway on five criteria: identity and OAuth support, tool-level permissions, audit and SIEM export, deployment options, and published UK location facts. We used vendor documentation dated up to 1 October 2026, treated vendor benchmarks as unverified, and omitted latency figures because none were independently reproduced. We did not test the products.
UK regulation and MCP gateways: what the guidance says
No UK government document names an "MCP gateway", and the NCSC's agentic AI guidance does not mention MCP. The guidance does describe controls that a gateway can supply.
| Guidance | Status | Control a gateway can supply |
|---|---|---|
| NCSC, managing agentic AI risk | Interim, 20 August 2026 | Unique agent credentials, deny-by-default tool access, immutable logs, central shutdown |
| NCSC, thinking before adopting agentic AI | 15 May 2026 | Least privilege and temporary credentials |
| DSIT AI Cyber Security Code of Practice | Voluntary, 13 principles | Supplier due-diligence questions |
| FCA PS26/2 | Effective 18 March 2027 | Register of material third-party arrangements |
Sources: NCSC (2026), NCSC (2026), DSIT (2025), FCA (2026).
On data, according to the ICO (2026), its Tech Futures paper on agentic AI is early thinking, not formal guidance, and flags unclear controller and processor roles. The Data (Use and Access) Act 2025 brought most provisions into force on 5 February 2026.

The top 5 MCP gateways for UK enterprise
Azure API Management
Azure API Management can expose REST APIs, or existing MCP servers, as governed MCP servers, with Entra or JWT authentication, rate limits, IP filtering and Azure Monitor. Microsoft's documentation lists limits: tools only (no resources or prompts) and no workspace support. For UK buyers, UK South and UK West are listed regions, but Microsoft's availability page noted temporary capacity limits for UK South v2 tiers (updated 27 August 2026).
Cloudflare MCP server portals
Cloudflare's portals reached general availability on 24 September 2026. They give one endpoint for many MCP servers, with Access policies, MFA, device posture, HTTP logging, DLP and Logpush to a SIEM. Cloudflare's Regional Services can restrict decryption to UK data centres. Its Zero Trust localisation page does not mention portals, so check whether portal logs respect that boundary.
Kong AI Gateway
The Enterprise MCP Gateway is part of Kong AI Gateway 3.12. It converts REST APIs into MCP servers, acts as an OAuth 2.1 resource server and adds MCP observability. It is proprietary and uses paid plugins, per Kong's October 2025 announcement. Kong's documentation says Dedicated Cloud Gateways can run in London, while Konnect control-plane geographies are Australia, EU, Middle East, US, India and Singapore. We did not verify that MCP features run on the London data plane.
NeuralTrust TrustGate (our product)
Agent Gateway (TrustGate) is NeuralTrust's AI gateway, with a separate MCP gateway layer. Its page lists role-based access control and read/write restrictions per tool, and NeuralTrust's own comparison (2026) cites 200+ third-party MCP servers and native SIEM export. The AI Gateway page lists SaaS, hybrid and on-premises options. We have not stated a UK hosting region because the pages reviewed do not name one, so ask NeuralTrust directly. Where others win: Kong and Azure offer wider API-management features, and Cloudflare offers a global network.
Solo.io agentgateway
agentgateway is an open-source data plane for MCP and agent-to-agent traffic, hosted by the Linux Foundation. Solo Enterprise adds tool fingerprinting and versioning against tool poisoning, token exchange, audit trails and 24/7 support, per Solo's October 2025 announcement. A standalone single-binary mode launched on 10 September 2026. We found no UK region information.
Also considered
IBM ContextForge (community-maintained), Docker's MCP Gateway (enterprise tier invite-only), Tyk, Obot and Lunar.dev's MCPX were also assessed. We did not shortlist them because their UK evidence or enterprise support terms were thinner.
MCP gateway security and governance for UK enterprise
A gateway reduces risk only if it enforces policy on every call. The core threats are prompt injection through tool output, token theft, over-broad tool permissions and unmonitored servers. According to the NSA's MCP guidance (2026), these issues cannot be fixed at isolated endpoints and need environment-wide controls.
CVE-2025-6514 shows the client side of the problem: according to JFrog (2025), a malicious authorisation endpoint could trigger command injection in mcp-remote (CVSS 9.6, fixed in 0.1.16).
How NeuralTrust addresses this
Agent Gateway (TrustGate) enforces per-agent and per-tool policy on MCP traffic. Agent Runtime Security (TrustGuard) inspects prompts, tool calls and outputs as they happen. AI Red Teaming (TrustTest) tests injection and tool-misuse paths before go-live, and Agent Posture Management (TrustLens) shows which agents reach which tools. NeuralTrust delivers these as the Runtime Security Mesh, and holds four Gartner Hype Cycle 2026 recognitions in AI Runtime Defense.
Which should you choose?
Choose by your existing estate, then verify UK location facts in writing.
| If you are... | Consider | Why |
|---|---|---|
| An Azure and Entra shop | Azure API Management | Native identity, UK South and UK West listed |
| A team wanting one access layer for staff and agents | Cloudflare portals | Access policies, DLP and UK decryption option |
| A platform team already on Kong | Kong AI Gateway | Same control plane and plugins |
| A security team where agent controls come first | NeuralTrust TrustGate (our product) | Per-tool RBAC, runtime inspection, red teaming |
| A Kubernetes team preferring open source | Solo.io agentgateway | Linux Foundation project with paid support |
Whichever you shortlist, ask in writing for the data-plane region, log location, sub-processors and audit export format.
Conclusion
The best MCP gateways for UK enterprise are the ones that enforce identity and per-tool policy on every call and can show where the data plane and logs sit. Kong, Azure API Management and Cloudflare publish UK-relevant options, Solo.io offers an open-source route, and NeuralTrust's TrustGate is built around agent security. Treat our listing as one input and verify every UK location claim with the vendor.

FAQs about MCP Gateways for UK Enterprise
1. What is an MCP gateway?
An MCP gateway is a proxy between AI agents and MCP servers that applies authentication, per-tool permissions, logging and policy to each call. It gives security teams one place to approve servers, restrict tools and export audit logs, which the MCP specification itself leaves optional (MCP specification, 2026).
2. Which MCP gateway is best for UK enterprise?
It depends on your estate. Azure API Management suits Azure and Entra teams, Cloudflare suits teams wanting one access layer, Kong suits existing Kong users, and Solo.io suits Kubernetes teams preferring open source. NeuralTrust's TrustGate, our own product, suits teams prioritising agent security. Verify UK data-plane and log locations in writing.
3. Does the UK require an MCP gateway?
No UK law or guidance names an MCP gateway. The NCSC's interim agentic AI guidance (20 August 2026) describes controls such as unique agent credentials, immutable logging and emergency shutdown, which a gateway can supply. That guidance is advisory, not mandatory (NCSC, 2026).
4. Can an MCP gateway run in a VPC or air-gapped environment?
Some can. Kong offers self-hosted deployment, Azure API Management has a self-hosted gateway option, Solo's agentgateway runs as a standalone binary, and NeuralTrust lists on-premises deployment. Check each vendor's documentation for the exact air-gapped scope, because management-plane connectivity requirements differ.
5. Do MCP gateways keep data in the UK?
Not automatically. Kong's Dedicated Cloud Gateways can run in London, Cloudflare offers a UK-only decryption region and Azure lists UK South and UK West, but each covers only part of the stack. Ask where the data plane, logs and control plane sit before you assume UK residency.
6. Why are traditional API gateways not enough for MCP?
API gateways manage requests to known endpoints. MCP traffic adds dynamic tool discovery, agent identities and tool descriptions that can carry injected instructions. The OWASP MCP Top 10 lists tool poisoning and context injection as distinct risks (OWASP, 2025, beta), so you need tool-aware policy.
7. What should a UK CISO ask an MCP gateway vendor?
Ask which region hosts the data plane, where logs are stored, who the sub-processors are, how per-tool permissions work and how audit exports reach your SIEM. Also ask for the UK GDPR transfer mechanism and whether the vendor supports your regulator's third-party reporting rules, such as FCA PS26/2.
