Today is the operative word: we check Source Map Parser MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This one needs environment variables set before it will start: SOURCE_MAP_PARSER_CONTEXT_OFFSET_LINE (Context lines around error locations in source code), SOURCE_MAP_PARSER_RESOURCE_CACHE_MAX_SIZE (Maximum memory cache size in MB for source maps). The author declared them in the registry entry; get the values from the project itself.

Source Map Parser MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Source Map Parser MCP?

Source Map Parser MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package source-map-parser-mcp was installed 78 times last week.

How do I connect Source Map Parser MCP?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls source-map-parser-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Source Map Parser MCP?

The npm package source-map-parser-mcp was installed 78 times in the last week. Week over week that is +34%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Source Map Parser MCP open source?

Yes — it is published under the MIT licence, written in TypeScript and 2 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
