How to Use the Fourier Transform Engine MCP in Windsurf

Q: How do I connect the Fourier Transform Engine to Windsurf?

Open your /.codeium/windsurf/mcpconfig.json file and add the server configuration under the mcpServers key. Once you hit refresh in the Windsurf MCP panel, Cascade instantly discovers the calculatefft tool.

Q: Can Windsurf use the Fourier Transform Engine to analyze stock market data?

Yes, Cascade uses the calculatefft tool to find repeating cycles in raw price arrays. It feeds the historical closing prices to the engine, extracts the dominant frequencies, and writes a trading strategy based on those cycles.

Q: Does the Fourier Transform Engine support non-power-of-two array lengths in Windsurf?

The calculatefft tool handles any array length by falling back to a standard discrete transform when the input size isn't a power of two. Windsurf passes the raw numeric array directly, and the engine returns the correct frequency bins regardless of sample size.

Q: Is my raw time-series signal data safe when using this MCP Server?

All numeric arrays sent to the calculatefft tool are processed locally inside a secure, ephemeral V8 isolate sandbox. Your raw signal data never leaves the local execution boundary, ensuring complete isolation from external networks.

Let Windsurf autonomously run spectral analysis on raw time-series arrays to extract dominant frequencies instantly.

Perplexity

Spot market cycles or signal anomalies autonomously

The `calculate_fft` tool registers directly with Windsurf so Cascade can analyze raw time-series data without manual prompting. You pass a raw array of stock ticks or sensor inputs, and Cascade chains the transform to find the dominant cycles. Cascade doesn't just run the math; it reads the returned frequency bins, writes a processing script, and plots the results. It handles the entire multi-step analysis sequence in one go.

Debug signal processing in Windsurf with this MCP Server

This MCP Server equips Cascade with the `calculate_fft` tool to dissect noisy signal arrays directly inside your workspace. Cascade spots the exact frequencies causing feedback or jitter without requiring external python scripts. You point Cascade to a raw audio buffer file. It reads the file, feeds the numeric array to the server, and rewrites your filter code based on the exact frequency peaks returned.

Automate frequency domain feature engineering

Feeding time-domain datasets into the `calculate_fft` tool lets Cascade extract frequency-domain features for your machine learning models. Cascade loops through your data directories, extracts the top frequency components, and appends them to your training set. It executes these steps sequentially, verifying the output shape at each step. You get clean spectral features injected directly into your pipeline without writing boilerplate mathematical code.

Setup guide

Set up Fourier Transform 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 Fourier Transform 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 Fourier Transform Engine payment history." If connected, Cascade will call the Fourier Transform Engine tools directly. You will see a green dot next to the server name in the MCP panel.
