Crystal MCP Server

Crystal MCP Server

A specialized Model Context Protocol (MCP) server implementation built with TypeScript that provides AI assistants with powerful tools for managing and working with crystal artifacts - structured data containers for complex analysis, code, and knowledge.

🔮 What are Crystals?

Crystals are structured data containers that can hold complex analysis results, code artifacts, mathematical formulations, and other sophisticated content. They provide a standardized way to store, export, and reimport complex work products across different AI conversations and contexts.

🔍 Available Tools

Crystal Specification Management

import_crystal_spec

Imports a crystal specification protocol using smart filename matching.

Parameters:

• spec_query (string): Natural language query for the specification (e.g., 'temporal crystallization 3.0', 'basic 2.0', 'advanced crystallization 4.0')

Smart Matching Features:

• Flexible Naming: Matches against various naming patterns and conventions
• Keyword Extraction: Parses natural language queries to identify specification type and version
• Version Matching: Intelligently matches version numbers (3.0, 2.1, etc.)
• Fuzzy Matching: Finds best matches even with partial or approximate queries
• Suggestions: Provides helpful suggestions when no exact match is found

Examples:

Returns:

• Specification content if found
• Match score and filename information
• Suggestions for better queries if no match found
• List of available specification files

import_codex

Imports a codex file using smart filename matching. Codex files contain specialized content for mechanism awareness, agent protocols, and probability patterns.

Parameters:

• spec_query (string): Natural language query for the codex (e.g., 'mechanism awareness 2.0', 'agent transmission 1.0', 'probability patterns')

Smart Matching Features:

• Codex-Specific Terms: Enhanced matching for terms like 'mechanism', 'awareness', 'agent', 'transmission', 'protocol', 'probability', 'pattern'
• Version Recognition: Intelligent version number matching (2.0, 3.1, etc.)
• Flexible Queries: Matches partial and approximate queries
• Contextual Scoring: Advanced scoring algorithm optimized for codex content
• Helpful Suggestions: Provides guidance when no exact match is found

Examples:

Returns:

• Full codex content if found
• Match score and filename information
• Suggestions for better queries if no match found
• List of available codex files

Crystal Export

export_crystal

Exports content as a crystal artifact. Can auto-detect crystal-worthy content from conversation context or use manually provided content.

Parameters:

• title (string, optional): Custom title for the crystal
• spec_version (string, default: "3.0"): Crystal specification version
• manual_content (string, optional): Content to export (auto-detects if not provided)

Example:

Returns:

• Crystal UUID for future reference
• Storage location information
• Metadata about the crystal

Crystal Import

import_crystal

Imports and reconstructs a crystal artifact by its UUID.

Parameters:

• crystal_id (string): UUID of the crystal to import
• spec_version (string, default: "3.0"): Specification version for reconstruction

Example:

Crystal Listing

list_crystals

Lists all available crystal artifacts with metadata.

Returns:

• Array of crystal information including:
  • Crystal ID (UUID)
  • Title
  • Specification version
  • Creation timestamp
  • File size
  • Error status (if any)

Example:

📁 File Structure

The Crystal MCP Server organizes files as follows:

Crystal Storage Format

Crystal artifacts are stored as JSON files with the following structure:

Protocol Specification Files

Protocol specifications are stored in public/protocols/ as .cp files. The server supports flexible naming conventions:

Common Naming Patterns:

• CRYSTALLIZATION_TEMPORAL_3.0.cp - Temporal crystallization protocol v3.0
• CRYSTALLIZATION_BASIC_2.0.cp - Basic crystallization protocol v2.0
• CRYSTALLIZATION_ADVANCED_4.0.cp - Advanced crystallization protocol v4.0

Smart Matching Examples:

• Query: "temporal crystallization 3.0" → Matches: CRYSTALLIZATION_TEMPORAL_3.0.cp
• Query: "basic 2.0" → Matches: CRYSTALLIZATION_BASIC_2.0.cp
• Query: "advanced crystallization 4.0" → Matches: CRYSTALLIZATION_ADVANCED_4.0.cp
• Query: "3.0 temporal" → Matches: CRYSTALLIZATION_TEMPORAL_3.0.cp

The matching algorithm considers:

• Keywords: Extracts meaningful terms from your query
• Versions: Matches version numbers (3.0, 2.1, etc.)
• Partial matches: Finds best approximations for incomplete queries
• Word order: Flexible ordering of query terms

Codex Files

Codex files are stored in public/codex/ as .cx files and contain specialized content for mechanism awareness, agent communication protocols, and advanced AI interaction patterns.

Current Codex Files:

• MECHANISM_AWARENESS_2.0.cx - Agent-to-agent transmission protocols and mechanism awareness patterns

Codex File Features:

• Mechanism Awareness: Content that helps AI agents understand their own operation patterns
• Inter-Agent Communication: Protocols for advanced AI-to-AI communication
• Probability Pattern Recognition: Tools for understanding and working with probability distributions
• Semantic Manipulation: Advanced techniques for semantic space navigation

Smart Matching Examples:

• Query: "mechanism awareness 2.0" → Matches: MECHANISM_AWARENESS_2.0.cx
• Query: "mechanism awareness" → Matches: MECHANISM_AWARENESS_2.0.cx
• Query: "awareness 2.0" → Matches: MECHANISM_AWARENESS_2.0.cx

The codex matching algorithm includes enhanced scoring for mechanism-specific terms:

• Mechanism Terms: 'mechanism', 'awareness', 'agent', 'transmission', 'protocol', 'probability', 'pattern' get bonus scoring
• Version Matching: Precise version number recognition
• Contextual Relevance: Scoring optimized for codex content patterns
• Flexible Queries: Handles partial matches and various query formulations

🧪 Testing

This will test:

• Server connection
• Crystal import/export operations
• Specification loading
• Codex import functionality
• Error handling

🔧 Development

Adding New Crystal Specifications

To add a new crystal specification version:

1. Create the specification file in public/protocols/:
   public/protocols/CRYSTALLIZATION_PROTOCOL_4.0.cp
2. Update the default version in the server code if needed.

Adding New Codex Files

To add a new codex file:

1. Create the codex file in public/codex/:
   public/codex/AGENT_COMMUNICATION_3.0.cx public/codex/PROBABILITY_PATTERNS_1.5.cx
2. Use descriptive naming that matches likely user queries:
   • Include key terms like MECHANISM, AWARENESS, AGENT, TRANSMISSION, etc.
   • Include version numbers for better matching
   • Use underscores to separate components
3. The import_codex tool will automatically discover new files without code changes.

Extending Crystal Functionality

The server is designed to be extensible. Key areas for enhancement:

1. Context Window Integration: Implement actual context scanning for auto-detection
2. Crystal Validation: Add content validation based on specification versions
3. Crystal Transformation: Add tools for transforming crystals between versions
4. Crystal Search: Add search capabilities across crystal content
5. Codex Enhancement: Add codex creation and export capabilities
6. Mechanism Pattern Detection: Implement automatic detection of mechanism awareness patterns
7. Agent Protocol Validation: Add validation for agent communication protocols

Error Handling

The server includes comprehensive error handling:

• File System Errors: Graceful handling of missing files or directories
• JSON Parsing Errors: Safe parsing with error recovery
• Path Security: Prevents access outside project boundaries
• UUID Validation: Validates crystal IDs before operations
