MCP and gateway

This is what kindling was born for.

Take an MCP server from npm or PyPI, stdio or HTTP, and turn it into a service that wakes up from a golden.

kling plugin install mcp
kling mcp search filesystem
kling mcp add io.github.domdomegg/filesystem-mcp
kling connect -all -install all

connect really checks

It runs a real MCP initialize before handing you anything.

Service:   eco
Endpoint:  http://192.168.2.60:8080/mcp/eco
Status:    ✓ kindling-echo v1.0.0 · 2 tool(s): echo, session_info

It writes the configuration for Claude Code, opencode, Cursor, VS Code, Windsurf, Cline and Zed.

The gateway

It takes the call, restores the snapshot, proxies it and freezes the machine once idle. It requires a token.

kling mcp serve -listen 127.0.0.1:8080 -idle 5m

Path	Latency
Cold (from the golden)	244 ms
Warm	9 ms
After an idle freeze	218 ms

Ephemeral: one microVM per action

kling mcp serve -ephemeral -prewarm 3

acción 1: 19 ms   pid=305 llamadas_en_esta_sesion=1
acción 2: 24 ms   pid=305 llamadas_en_esta_sesion=1
acción 3: 19 ms   pid=305 llamadas_en_esta_sesion=1

No action sees what the previous one did. 2 ms of execution, 19 ms end to end.

One microVM per session

kling mcp isolation notes session

Each session gets its own machine and its own disk. First initialize: 70 ms versus 765 ms.
