Json5 Mcp

Overview

Json5 Mcp is a Model Context Protocol server that parses JSON5 syntax—including comments, trailing commas, and unquoted keys—and converts it to strict JSON. By implementing MCP, it lets AI assistants call this conversion as a tool rather than requiring manual copy-paste workflows between applications.

The server runs entirely on your local machine through the npm package @mukundakatta/json5-mcp, communicating over stdio with no authentication required. Install it with npx -y @mukundakatta/json5-mcp and start using it immediately. The latest release is v0.1.0, distributed under the Apache-2.0 license with source code available at MukundaKatta/mcp-stack on GitHub.

Json5 Mcp is listed in the Development category on mcp.site and integrates with any MCP-compatible client, including Claude Desktop, Claude Code, Cursor, VS Code, and others. If you maintain this project, claim this listing to verify ownership and keep the information accurate.
