One connection.Infinite memory.
Each AI client gets a dedicated persistent instance. The SSE stream stays open, context accumulates across every tool call — your MCP server remembers everything.
Built for Persistence
Every feature in Vinkius is engineered around one principle: your MCP session never dies. Dedicated instances, persistent connections, and zero-loss context — by design, not by workaround.
Zero Cold Starts
Your MCP server instance is always warm. V8 snapshots pre-load your handler definition so execution begins in microseconds. Every tool call starts instantly — no spin-up, no waiting.
Persistent Context
Session state accumulates naturally across tool calls. No external stores, no serialization overhead. Your first tool call's context is still alive on the hundredth.
No Execution Limits
SSE connections run as long as your AI client needs them. Long-running agent conversations, multi-step workflows, complex reasoning chains — the connection stays open.
Clean Lifecycle
Every connection is tracked with heartbeat monitoring. When a client disconnects, the instance is surgically cleaned — transport deleted, isolate destroyed, zero orphans.
One Instance.
One Client.
Persistent.

Kill Any One.
Your dashboard shows every active SSE session in real-time. Client IP, user agent, token name, connection duration — all visible. One click terminates a specific connection via Redis pub/sub. No restart required, no collateral damage.
Real-Time Visibility
Every active SSE connection displayed with IP, agent, token name, and duration. Updated by heartbeat.
Surgical Termination
Kill one connection without affecting others. Redis pub/sub propagates to all runtime replicas instantly.
Token-Level Isolation
Each connection is authenticated by a unique token. Revoke a token and all its connections drop immediately.
Server Toggle
Deactivate an entire MCP server with one click. All SSE connections are killed, all tokens invalidated. Reactivate when ready.
Security is not a feature.
It is the architecture.
Every handler runs inside a sealed V8 isolate. No eval. No network escape. No file system access. If the CPU budget expires, the isolate is terminated — no negotiation.
V8 Isolate Sandbox
Each deployed handler runs in its own V8 isolate. Memory-isolated, no shared state, no access to the host process. AST-level stripping ensures your source code is never readable.
DLP In-Flight
Sensitive data patterns are scanned in every response before it reaches the AI client. Detected matches are redacted in memory, never logged, never persisted.
CPU Guillotine
5-second hard timeout per tool execution. If a handler enters an infinite loop or runaway computation, the isolate is terminated instantly. No negotiation, no grace period.
AbortController Cascade
When a TCP connection dies, an AbortController signal cascades through every pending fetch, timer, and promise. The isolate lifecycle is bound to the connection lifecycle. Zero zombie processes.
OpenTelemetry Native
Every governance operation emits structured spans — contract materialization, lockfile generation, introspection validation. Export to Jaeger, Datadog, or your own collector.
Open Source Core
Vurb.ts Framework is Apache 2.0-licensed. The governance rules, introspection engine, and CLI are fully auditable. Zero black boxes. Read every line before you trust us with your infrastructure.
