Connecting an AI Assistant

This guide connects Claude to the NodePit MCP server and asks a few first questions about KNIME, so you can see the whole chain (assistant, lookup, answer) work before you rely on it. The same steps apply to any other assistant that supports MCP; only the screen where you add the server looks different, and Connect your assistant has the steps for each.

Add the server

The NodePit server needs no account and no key. Its address is https://nodepit.com/mcp.

In Claude, go to Customize → Connectors and choose Add custom connector. Paste the address, click Add, and Claude shows NodePit in your list of connectors. There is no sign-in step.

Switch it on for a chat

Open a new chat, click +, and switch NodePit on under Connectors. Claude only uses a connector that is on for the chat.

Ask your first questions

Back in the chat, try:

Which KNIME nodes can read Parquet files, and which extension do I have to install for them?

Claude searches NodePit, opens the nodes that match, and answers with their names and the extension each one ships in. You see the lookups in the reply, as small notes such as search and get_node, which tell you that the answer comes from NodePit and not from memory.

Pick a node from the reply and ask about it:

What does the first one do, and what are its ports?

Claude opens the node and tells you what it found: the description, the ports, and where the node sits in the node repository.

Ask for what you need

From here, describe what you need, as you would to a colleague. Ask which node usually follows another, whether a node is deprecated and what replaces it, or which KNIME version is the latest. If an answer sounds like a guess, ask Claude to “check NodePit”.
