Koskamo

source-map-parser-mcp

A community-driven MCP server that parses JavaScript error stack traces back to original source code using source maps. It allows developers to quickly identify and resolve issues by mapping minified code locations to their original source context, supporting both CLI usage and embedding into custom MCP server processes.
