How to Use the K-Fold Split Engine MCP in Windsurf

Q: How does the K-Fold Split Engine work with Windsurf's Cascade?

Cascade calls the calculatekfold tool directly when you ask it to prepare cross-validation splits. It reads your dataset size, gets the split indices from the server, and automatically writes the partition logic into your training pipeline.

Let Cascade autonomously partition training data and run validation loops with the K-Fold Split Engine in Windsurf.

Let Windsurf Cascade Handle Your Validation Splits

The `calculate_kfold` tool generates exact index splits directly inside your Windsurf IDE. Cascade reads your local data file structure, plans the partitioning strategy, and feeds these index arrays into your training script without you writing boilerplate split code. Your Windsurf agent executes the split logic, checks the distribution, and immediately updates your config files. This MCP server cuts down manual index slicing to zero, letting Cascade focus entirely on tuning model parameters.

Eliminate Data Leakage in Multi-Step Workflows

The `calculate_kfold` tool prevents test data from bleeding into your training sets during complex model evaluations inside Windsurf. Cascade chains this tool with your local training runs, ensuring your model never trains on validation rows. You get clean, independent train and test index arrays for Cascade to route. Cascade handles the file routing, making sure the model evaluates only on the correct partition.

Run Autonomous Cross-Validation Pipelines

The `calculate_kfold` tool outputs precise index arrays that Cascade feeds directly into your test runner. This MCP server lets your Windsurf agent spin up multiple training processes sequentially, using the exact boundaries generated for each validation step. Instead of writing loops by hand, you tell Cascade to run a 5-fold evaluation. Your Windsurf agent handles the execution, collects the metrics, and reports the final average validation loss.

Setup guide

Set up K-Fold Split Engine MCP in Windsurf

Prerequisites

Windsurf IDE installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Click the Cascade assistant icon in the sidebar, then click the hammer icon (🔨) at the top of the panel. Select "Configure" to open ~/.codeium/windsurf/mcp_config.json.
2

Add the K-Fold Split Engine MCP

Paste the JSON snippet shown on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Refresh MCPs

Go back to the hammer icon (🔨) in Cascade and click "Refresh". Windsurf will detect the new server. No full restart is needed — the connection is hot-reloaded.
4

Verify in Cascade

Start a new Cascade conversation and ask something like "Show my K-Fold Split Engine payment history." If connected, Cascade will call the K-Fold Split Engine tools directly. You will see a green dot next to the server name in the MCP panel.

Common questions about K-Fold Split Engine MCP in Windsurf

Cascade calls the `calculate_kfold` tool directly when you ask it to prepare cross-validation splits. It reads your dataset size, gets the split indices from the server, and automatically writes the partition logic into your training pipeline.

Yes, you can specify the exact number of folds you need directly in your prompt. Cascade passes this configuration to the `calculate_kfold` tool and sets up the corresponding training loops in your workspace.

This server currently generates standard, non-overlapping index splits for validation. Cascade will use these indices to partition your tabular arrays, ensuring no data point overlaps between your train and test sets.

Open your Windsurf settings, navigate to Cascade MCP Servers, and add the configuration under the `mcpServers` key. Alternatively, you can edit your `~/.codeium/windsurf/mcp_config.json` file directly to register the tool.

Absolutely. The server only processes index counts and partition sizes to generate the split arrays, meaning your actual training data never leaves your local machine. All index calculations occur within a secure, isolated sandbox environment.
