Build Faster, Deploy Securely
AI Workflows and components like MCP Servers introduce Agentic Specific Risks - the same non-deterministic inputs and outputs that create the value in agentic AI also give rise to threats like improper input/output handling, parsing vulnerabilities, privilege escalation, data exfiltration, and more.
With Cosmonic Control you can integrate sandboxed MCP servers into your existing K8s Platforms on any cloud, on-premises, or on any edge. Leverage your existing investments in pipelines, K8s operations, ingress/egress, and observability - deploy faster, but with a safety net.

Instantly Sandbox MCP
With Cosmonic Control and CNCF wasmCloud.
OpenAPI Specs to MCP
Instantly generate sandboxed MCP servers that expose your APIs through secure, contract-driven WebAssembly interfaces from your existing OpenAPI Specifications.
Observability
With built-in support for OpenTelemetry, dashboards and more—traces, logs, and metrics are a breeze.
Authentication
Secure applications effortlessly with built-in authentication using API Keys, OAuth 2.0, Mutual TLS, and JSON Web Tokens for safe, ready-to-use access control.
Portability
Sandbox MCP makes it easy to run MCP servers on-premises, in the cloud, or anywhere it makes sense. Native K8s support makes enterprise adoption simple.
Secure Virtual Capabilities
Leverage WebAssembly’s ability to virtualize contract-driven APIs and virtual filesystems, enabling isolated components to interact safely through precisely defined, policy-enforced boundaries.
Sandboxed MCP
Secure capability-driven sandboxes with CNCF wasmCloud limit the impact of LLM prompt injection, data exfiltration, and lateral movement.
Why use WebAssembly to Sandbox MCP?
WebAssembly embraces first principles - deny-by-default, capability driven security, and scaling to zero with zero cold starts. Compatible with your existing infrastructure on premises, in the cloud, or on the edge.
How is WebAssembly Security different from containers or VMs?
Wasm uses a capability-based security model. Code runs with zero default privileges and can only call APIs you explicitly expose. Unlike containers, which assume a full Linux kernel and then try to bolt on seccomp/AppArmor, Wasm starts at zero and adds just what’s needed — dramatically shrinking the attack surface.
Why does “scale to zero” matter for MCP?
MCP servers are often idle until an AI agent calls them. Wasm components can start in milliseconds and consume almost no resources when idle. That means you can run hundreds or thousands of isolated MCPs without paying a container tax or keeping dormant pods alive.
How does Wasm portability help my enterprise architecture?
Wasm runs the same binary anywhere: dev laptops, edge gateways, or multi-cloud clusters. This eliminates drift between environments and makes MCP extensions easy to move, test, and redeploy without re-platforming.
Can I leverage my existing Kubernetes investments?
Cosmonic extends Kubernetes with a control plane for Wasm components. You keep your existing K8s infrastructure — networking, monitoring, RBAC — but gain a secure, lightweight substrate to run MCP sandboxes side by side with containers. This lets platform teams build better together: reuse K8s governance and observability while introducing Wasm’s speed and safety for AI-driven workloads.
How does this approach future-proof my AI/agent strategy?
As MCP adoption grows, so will the need to run untrusted or partner-supplied servers safely. Wasm provides a stable, forward-compatible sandbox model that works across clouds and chips, while Cosmonic keeps the operational model aligned with Kubernetes and cloud-native tooling you already own.
Where does this run — cloud or on-premises?
Anywhere you already run Kubernetes. WebAssembly sandboxes work on all major K8s distributions — including Amazon EKS, Google GKE, Azure AKS, Red Hat OpenShift, VMware Tanzu, Rancher, Canonical Charmed K8s, SUSE NeuVector, and upstream open-source Kubernetes.
Cosmonic’s control plane layers on top, so you can run MCP sandboxes in the cloud, on-prem, or hybrid without changing your cluster strategy. If it’s Kubernetes, it works.
