JSON MCP Filter

Example Use Cases

• 1

  Extract only specific fields from large JSON responses or files to reduce LLM context size and noise.

• 2

  Generate TypeScript interfaces from JSON payloads to enforce type safety when consuming external APIs.

• 3

  Fetch and preprocess JSON from remote HTTP/HTTPS endpoints with automatic chunking and size protection before passing data to an LLM.

Description

JSON MCP Filter provides JSON-to-TypeScript schema generation (via quicktype) and shape-based filtering tools for local files and remote APIs. It supports automatic chunking for large datasets, enforces a 50MB safety limit, and returns clear, actionable errors for network and format issues. The tool is designed to reduce noisy JSON payloads into concise LLM-ready context and integrates with MCP clients like Claude Desktop and Claude Code.
