How to: VS Code Agent Toolbox chat_gpt_oss_120b
Add Agent Toolbox to VS Code
-

{
"servers": {
"agent-toolbox": {
"type": "http",
"url": "https://agent-toolbox.zafermemon87.workers.dev/mcp"
}
}
}-
02
Save the file and restart VS Code.

03
Ask for something chat_gpt_oss_120b does. VS Code lists the server's tools on connect and calls chat_gpt_oss_120b itself — you do not invoke it by name.

If nothing happens, check the server is running and that Agent Toolbox's identifier in your config matches the one above exactly.

Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 24 October 2026. It is what
the server actually exposes, not what its listing claims.
Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
