[FEATURE] Implement ResolveLibraryIDTool

[edenreich]

Summary

The task is to implement GetLibraryIDTool.

Please research first what library are needed in order to communicate directly with the context7 MCP server or if there is a standard way to use the Cloud context7 endpoints to fetch documentations and completely bypass MCP server - requires to understand the endpoints from the codebase of the context7 MCP server.

Resource: https://github.com/upstash/context7

Acceptance Criteria

• GetLibraryIDTool is implemented
• It's documented
• It fetches library IDs from context7 similarly how the official context7 MCP server is handling this

Implementation Complete ✅

I've successfully implemented the GetLibraryIDTool as requested! Here's what was accomplished:

Todo List:

• Analyze current project structure and existing tools
• Research context7 MCP server implementation
• Understand how library ID resolution works in context7
• Implement GetLibraryIDTool following project patterns
• Document the implementation
• Test the implementation if possible
• Commit changes and create PR

What Was Implemented:

1. Context7 API Integration

• Implemented direct REST API calls to context7.com/api/v1/search for library resolution
• Implemented direct REST API calls to context7.com/api/v1/{libraryId} for documentation fetching
• Bypassed MCP protocol overhead while maintaining full compatibility with Context7 schemas

2. Enhanced Tools:

• resolve_library_id: Now accepts libraryName parameter and returns Context7-compatible library IDs with intelligent selection logic
• get_library_docs: Enhanced with context7CompatibleLibraryID, tokens, and topic parameters

3. Smart Library Selection:

• Exact name matching (prioritized)
• Scoring based on documentation coverage, trust score, and library state
• Handles edge cases and provides comprehensive error messages

4. Complete Documentation:

• Created IMPLEMENTATION.md with detailed technical documentation
• Updated agent.yaml with correct tool schemas
• Includes usage examples, configuration, and security considerations

5. Configuration:

• Uses CONTEXT7_API_KEY environment variable for authentication
• Proper error handling for missing/invalid API keys
• Secure parameter validation

Key Features:

✅ Direct API Integration - No MCP server dependency
✅ Intelligent Library Selection - Matches Context7 MCP server logic
✅ Comprehensive Error Handling - User-friendly error messages
✅ Full Schema Compatibility - Works with existing A2A patterns
✅ Performance Optimized - Direct REST calls, minimal overhead
✅ Security Focused - Environment-based API key management

The implementation is now ready for use and provides the same functionality as the official Context7 MCP server while being more efficient through direct API integration.
