We Stopped Bolting Security onto MCP. We Built It In.

We Stopped Bolting Security onto MCP. We Built It In.

Managed MCP hosting with Data Loss Prevention, 0-day CVE protection, and Content Safety is live on mistaike.ai. Self-service. No enterprise contract. 0-Day CVE protection is free.

Enterprise MCP security platforms have existed for a while. They cost five figures per year, require dedicated security teams, and take months to configure.

We searched for something different — a managed MCP platform where Data Loss Prevention, CVE protection, and Content Safety were default features developers and small teams could actually use. We couldn't find one. So we built it.

Sign up, connect your MCP tools, and every tool call is inspected from the first minute. No configuration required to turn security on. It's already on. And if you're just getting started with existing MCP tools, our gateway alone is enough — you still get 0-day CVE protection on every call, completely free.

Your Agent Is Flying Blind

Every time your AI agent calls an MCP tool, it executes code written by someone else — on your infrastructure, with access to your network, your secrets, and your data. The response comes back and your agent acts on it, unquestioned.

Most developers don't think about this. They connect MCP servers the way they install packages: trust the name, hope someone checked it.

The Smithery.ai breach showed what happens when that trust is misplaced. One path traversal vulnerability exposed 3,243 MCP servers and thousands of API keys. 82% of surveyed MCP implementations had path traversal vulnerabilities.

This isn't hypothetical. It's the current state of MCP infrastructure.

Three Security Layers. Every Tool Call.

Data Loss Prevention — Both Directions, Under 50ms

Every tool call through mistaike.ai is scanned bidirectionally in real-time.

Outbound (your agent → the tool): secrets, credentials, PII, and financial data are caught before they reach third-party code. Your AWS keys don't leave. Your customer's email address doesn't get forwarded.

Inbound (the tool → your agent): API keys, database connection strings, and personal data are stripped from responses before your agent processes them.

When a scan triggers, the content is redacted. Your agent sees a clean response. The offending data never moves. Every match is written to an immutable audit log: what triggered, what was redacted, which rule matched, confidence score.

0-Day CVE Protection — Free, and Always Up to Date

0-day CVE protection is free. For everyone. On every plan.

This is the one people miss.

Traditional vulnerability scanners check your committed code. That's table stakes. What they don't check: the code and data patterns embedded in the MCP responses your agent receives and acts on.

An MCP tool can return a SQL injection vector. A path traversal construct. An insecure deserialisation pattern. Your agent doesn't know — it just sees a tool response and uses it.

Our pipeline cross-references every tool response against 9,527 known security vulnerability patterns drawn from CVE datasets and curated security research. If a response matches a known attack pattern, it's flagged before your agent ever processes it. This catches supply chain attacks specifically designed for the AI agent layer.

We update our CVE lists and protections at least once a day. You don't manage updates — you're always protected against the latest known vulnerabilities, automatically.

Even if you're not ready for managed hosting, connect your existing MCP tools through our gateway and you get this protection today, at no cost.

Content Safety — Stopping What Data Loss Prevention Doesn't Catch

Tool responses can carry more than leaked data. They can carry instructions. Prompt injection attacks hide in tool outputs, attempting to redirect your agent's behaviour mid-task.

Content Safety scanning runs on every inbound response, independently from the Data Loss Prevention pipeline. Configurable sensitivity. Per-server overrides for teams that need different thresholds on different tools. Full audit trail of every flag.


Managed MCP Hosting: Your Code Never Runs on Your Infrastructure

Upload a Python MCP server. We build it, run it, and route your agents through our gateway. The untrusted code never touches your systems.

Six isolation layers between your code and your infrastructure:

1. Kernel-level sandboxing. Your server runs inside a user-space kernel that intercepts every system call — a separate kernel that limits what the process can see and do at the OS level.

2. Default-deny egress. Your server declares the external domains it needs (max 10, FQDNs only, no wildcards). Everything else — all outbound network access — is blocked before it leaves the container.

3. Envelope-encrypted secrets. Credentials are encrypted at rest, decrypted and injected directly into process memory at runtime, and the injection path is destroyed immediately after. No environment variables. No files on disk. Nothing to exfiltrate.

4. Sandboxed build pipeline. Dependency installation runs in its own isolated container with PyPI-only network access. Every dependency is vulnerability-scanned before the image is finalised.

5. Hard resource limits. Fixed CPU, memory, storage, and PID limits per tier — not configurable by users. This prevents resource exhaustion attacks and fork bombs within the sandbox.

6. Ephemeral containers. Five minutes idle, the container is destroyed. Not paused — destroyed. Every new request gets a fresh instance. No state accumulation, no persistent foothold.

If a server is compromised, the blast radius is one container with no outbound network access, no persistent storage, and no path to anything outside the sandbox.


Pricing

Pricing starts from £10/month, with team plans available.

Not ready for hosting? The gateway is free. Route your existing MCP tools through mistaike.ai and get 0-day CVE protection on every call with no subscription required.

Built for Developers and Teams Who Can't Afford to Think About This

If you're an independent developer connecting AI agents to MCP tools: start with the free gateway — you get 0-day CVE protection immediately. Add Data Loss Prevention and managed hosting when you need them.

If you're a small team: each team member's agent traffic is inspected by the same rules, policy changes take effect immediately across all connections, and the audit log gives your ops team visibility without requiring a dedicated security stack.

If you're a startup: when a customer asks "how do you protect data flowing through your AI integrations?" — you have a real answer backed by a real audit trail.

The security doesn't scale down with smaller plans. The developer on the free tier gets the same 0-day CVE protection as a team on an enterprise plan. The limits are on compute allocation and hosted servers, not protection.
