JSON MCP Filter
ไปฅไธๆๅฝ่ช่ฏฅไปๅบ็ README๏ผ็ๆฎต๏ผ ยท ๅจ GitHub ่ฏปๅฎๆด README โ
A powerful Model Context Protocol (MCP) server that provides JSON schema generation and filtering tools for local files and remote HTTP/HTTPS endpoints. Built with quicktype for robust TypeScript type generation.
**Perfect for**: Filtering large JSON files and API responses to extract only relevant data for LLM context, while maintaining type safety.
โจ Key Features
- ๐ **Schema Generation** - Convert JSON to TypeScript interfaces using quicktype
- ๐ฏ **Smart Filtering** - Extract specific fields with shape-based filtering
- ๐ **Remote Support** - Works with HTTP/HTTPS URLs and API endpoints
- ๐ฆ **Auto Chunking** - Handles large datasets with automatic 400KB chunking
- ๐ก๏ธ **Size Protection** - Built-in 50MB limit with memory safety
- โก **MCP Ready** - Seamless integration with Claude Desktop and Claude Code
- ๐จ **Smart Errors** - Clear, actionable error messages with debugging info
๐ ๏ธ Available Tools
json_schema
Generates TypeScript interfaces from JSON data.
**Parameters:**
- filePath: Local file path or HTTP/HTTPS URL
**Example:**
json_filter
Extracts specific fields using shape-based filtering with automatic chunking for large datasets.
**Parameters:**
- filePath: Local file path or HTTP/HTTPS URL
- shape: Object defining which fields to extract
- chunkIndex (optional): Chunk index for large datasets (0-based)
**Auto-Chunking:**
- โค400KB: Returns all data
- >400KB: Auto-chunks with metadata
json_dry_run
Analyzes data size and provides chunking recommendations before filtering.
**Parameters:**
- filePath: Local file path or HTTP/HTTPS URL
- shape: Object defining what to analyze
**Returns:** Size breakdown and chunk recommendations

Large Dataset Workflow
๐ Security Notice
**Remote Data Fetching**: This tool fetches data from HTTP/HTTPS URLs. Users are responsible for:
โ **Safe Practices:**
- Verify URLs point to legitimate endpoints
- Use trusted, public APIs only
- Respect API rate limits and terms of service
- Review data sources before processing
โ **Maintainers Not Responsible For:**
- External URL content
- Privacy implications of remote requests
- Third-party API abuse or violations
๐ก **Recommendation**: Only use trusted, public data sources.
