JSON Filter
Converts JSON samples into TypeScript type definitions and filters large JSON files to extract only specified fields, eliminating unwanted data from LLM context through shape-based filtering with simple object notation.
About
A TypeScript-based MCP server that provides JSON schema generation and filtering tools using quicktype-core to convert JSON samples into TypeScript type definitions and extract specific fields from large JSON files. Built by kehvinbehvin, it addresses the common problem of including unwanted data from large JSON files in LLM context by offering shape-based filtering that allows users to specify exactly which fields to extract using a simple object notation. The server integrates seamlessly with Claude Desktop and Claude Code, making it particularly valuable for developers working with APIs, data analysis, or any workflow involving large JSON datasets where selective data extraction is needed.
