MCP JSON Tools provide powerful data manipulation and querying capabilities for local JSON and NDJSON files using Lodash and JSONPath.
MCP JSON Tools is a versatile toolset designed to interact with local JSON and NDJSON files. It leverages Lodash for data manipulation and JSONPath for querying, allowing users to perform complex data operations efficiently. The tools support unified format handling, enabling seamless reading of both JSON and NDJSON formats. Users can query data using JSONPath expressions, inspect data nodes, and execute JavaScript for analysis or modification within a secure, sandboxed environment. The tools are easy to set up and run as a standard Node.js process via npx, ensuring safe execution with configurable timeouts.
