unstringify

Overview

unstringify is an MCP server that helps fix broken JSON, validate data, convert between formats, and read CSV, NDJSON, and log files as structured records. It also unpacks and compares data to help you work with messy or malformed data sources. Once connected to your MCP client, it exposes these capabilities as tools your AI assistant can invoke directly.

The server runs entirely locally on your machine via the npm package @unstringify/mcp, communicating over stdio with no external dependencies or authentication required. Version v0.1.1 is the latest release. You can install it right away with npx -y @unstringify/mcp.

stringify belongs in the Development category and integrates with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you maintain this server, claim your listing on mcp.site to earn the Verified badge and keep information accurate.
