About This MCP Server
1. Stack Parsing: Parse the corresponding source code location based on provided line number, column number, and Source Map file. 2. Batch Processing: Support parsing multiple stack traces simultaneously and return batch results. 3. Context Extraction: Extract context code for a specified number of lines to help developers better understand the environment where errors occur. 4. Context Lookup: Look up original source code context for specific compiled code positions. 5. Source Unpacking: Extract all source files and their content from source maps.
To modify the parsing logic, edit the getSourceToken method in the parser.ts file.
In the server.ts file, new tool interfaces can be added using the server.tool method.
