LangGraph

Install and activate first — Getting started covers both. Without a key the wiring below succeeds and the server refuses with E_NO_KEY the moment your editor starts it.

The same one-session MCP adapter as LangChain, placed in your graph’s tool node.

Get the descriptor

cd ~/your-project
kscope init --no-wire
kscope profile import default ~/your-project/.kaleidoscope
kscope profile launch default

Copy command and args into the adapter’s server definition. Any other MCP client explains each field.

Wire it in

Open the adapter before you execute the graph, pass search and remember into the tool node, and close it once execution finishes. Node calls reuse the same session.

Do not use Kaleidoscope as a checkpointer or a BaseStore.

Check it

The tool node should hold search and remember, and your checkpointer should be something else.

Remove it

Close the adapter after the graph finishes and delete the server definition from your own configuration.
