Add ASON MCP Server Extension

Description

Model Context Protocol server extension for ASON compression/decompression. Reduces JSON tokens by 20-60% for LLM interactions while maintaining 100% lossless fidelity.

Extension Details

• ID: ason-mcp
• Name: ASON MCP Server
• Repository: https://github.com/ason-format/zed-extension
• Version: 1.0.0
• Type: Context Server (MCP)

Features

• compress_json - Compress JSON to ASON format (20-60% token reduction)
• decompress_ason - Decompress ASON back to JSON (lossless)
• get_compression_stats - Analyze compression metrics without performing compression
• configure_compressor - Customize compression settings

Use Cases

• Reduce token costs when working with large JSON datasets
• Optimize AI assistant context with compressed data
• Analyze data efficiency before committing to compression
• Store compressed data in databases or configs

Technical Details

• Built with Rust using [email protected]
• Compiles to WebAssembly for native Zed integration
• Auto-installs @ason-format/mcp-server from npm using npm_install_package API

Configuration Example

Users enable the extension in their settings.json:

{
  "context_servers": {
    "mcp-ason": {
      "source": "extension",
      "enabled": true,
      "settings": {
        "indent": 1,
        "delimiter": ",",
        "use_references": true,
        "use_dictionary": true
      }
    }
  }
}

What is ASON?

ASON (Aliased Serialization Object Notation) is a token-optimized JSON compression format designed specifically for LLMs. It uses multiple compression techniques:

1. Uniform Arrays: [2]@id,name,age
2. Object References: &obj0
3. Value Dictionary: value #0
4. Path Flattening: user.profile.name:Alice

Achieves 20-60% token reduction while maintaining 100% lossless round-trip fidelity.
