Fix malformed JSON in Claude Desktop

Stop wasting time manually fixing trailing commas or single quotes in your local configuration files. The `parse_json5` tool acts as a bridge, reading non-standard syntax and converting it into strict JSON that your system can actually process. Your AI client sends raw, messy output to this MCP Server. It returns a sanitized, RFC-compliant string, meaning you can stop writing regex cleanup scripts and just get back to your actual work.

Handle comments in Claude Desktop configs

Most standard parsers choke when they see comments buried in your JSON files. This tool ignores those comments entirely, stripping them out during the conversion process so your data remains functional. By routing your files through `parse_json5`, you ensure that even the most human-readable, commented-up files are ready for machine consumption. It is the fastest way to get legacy configs into a modern format.

Unquoted key conversion

Human-written JSON often forgets quotes around keys, which breaks most strict loaders. This MCP Server identifies those missing quotes and inserts them automatically during the parsing phase. Once the `parse_json5` tool finishes its pass, you get a clean output that adheres to strict standards. It removes the friction of debugging syntax errors when you are just trying to move data between services.
