MCP.Pizza Chef: LSTM-Kirigaya

Built for people creating their own MCP servers, this VS Code extension (it also runs in Cursor and Trae) puts an inspector and a chat client side by side: call a tool, see exactly what comes back, then hand that same tool to a model and watch it decide when to use it. It handles several servers at once, saves your testing work between sessions, and connects to DeepSeek, OpenAI, Gemini, Grok, Qwen, Kimi, Mistral, Perplexity, and local models. You supply your own model key.

openmcp-client FAQ

Which editors does it work in?

VS Code, and also Cursor and Trae, which are built on the same foundation.

Do I need a key?

Yes, you bring your own model key. It supports DeepSeek, OpenAI, Gemini, Grok, Qwen, Kimi, Mistral, Groq, Perplexity, and OpenRouter, plus local models through Ollama.

Is this for people who just want to use MCP servers?

Not really. It is a workbench for building and debugging your own servers, rather than an everyday assistant.

Can I use this to work out why a tool is failing?

Yes. You can call the tool directly and read the raw reply, then try the same request through a model to see where things go wrong.

Does it cost anything?

The extension itself is free and open source. You only pay whatever your chosen model provider charges.

Can it handle more than one server at a time?

Yes. Connecting to several at once is supported, and there is a management panel for both project-level and global setups.
