Deterministic data extraction in Windsurf

Cascade doesn't need to guess where your data hides. Use `extract_pattern` to pull every email, URL, or phone number out of massive log files or documentation blocks. It returns clean, unique results every time. Windsurf chains this with file writes to keep your data structures accurate.

Sanitize PII before committing code

Stop leaking credentials or contact info. Run `mask_sensitive_data` to scrub PII from your text blobs before Windsurf saves them to your repository. It replaces matches with [REDACTED] tags. You get clean, safe files without the risk of accidental exposure.

Strict format validation for your inputs

Verify your user data before it hits the database. Use `validate_pattern` to confirm a string matches the expected email or phone format. It returns a simple boolean. Windsurf uses this to halt bad data before it causes downstream failures.

Setup guide

Set up Regex Toolkit 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 Regex Toolkit 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.

Verify in Cascade

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

Common questions about Regex Toolkit MCP in Windsurf

Open your MCP settings in the Cascade panel. You can add the server definition directly to your config file or use the built-in marketplace for one-click setup.

No. It uses standard regular expressions. It either matches or it doesn't, so you never have to worry about hallucinations.

Yes. Cascade can read your logs, run the extraction tool, and format the output into a new file automatically.

It runs in a sandbox. Your data stays isolated and the server doesn't keep a history of what you process.

The tools return a clear error or a false validation result. You can handle the failure in your agent's control flow.
