Run string comparisons locally in Claude Desktop

Stop guessing if your data strings match and start measuring. This MCP server lets your agent run `calculate_fuzzy_distance` without sending your text to any external API. You keep your data on your drive. The server processes everything inside your local environment, ensuring that Claude Desktop never touches your sensitive strings during the calculation.

Choose your matching algorithm

Different data needs different math. Use `calculate_fuzzy_distance` to toggle between Levenshtein, Jaro-Winkler, or Dice coefficients based on what you are actually trying to catch. Names often have transpositions, while longer text blocks need more nuance. You decide the logic by passing the correct algorithm parameter to the tool.

Validate user input instantly

Feed messy user input into the `calculate_fuzzy_distance` tool to filter out typos before they hit your database. It turns vague user requests into clean, actionable data. Claude Desktop calls this tool to compare inputs against your known schema. You get a deterministic score back immediately, letting the agent decide if a match is close enough to act.

Common questions about Fuzzy String Distance Engine MCP in Claude Desktop

Yes, absolutely. Since this MCP server runs as a local subprocess, it functions perfectly without an internet connection. Claude Desktop communicates with the engine over stdio.

Your data never leaves your machine. Because the server runs locally, the Fuzzy String Distance Engine keeps all text processing within your own environment, away from any remote servers.

Open your `claude_desktop_config.json` file. Add the server under the `mcpServers` key with the execution command, restart the app, and you are ready to go.

The engine includes Levenshtein, Jaro-Winkler, and Dice. You select these via the `calculate_fuzzy_distance` tool parameters.

No. This tool is ephemeral and stateless. It takes your two strings, computes the distance, returns the result, and forgets everything immediately after.
