## Overall Assessment

### Protocol Compliance
- ✅ MCP Protocol 2025-03-26 support
- ✅ Backward compatibility with 2024-11-05
- ✅ Proper capabilities declaration
- ✅ JSON-RPC 2.0 compliance

### Tool Schema Quality
- ✅ Human-readable tool titles
- ✅ Proper behavior annotations
- ✅ No dummy parameters in no-param tools
- ✅ Valid JSON schema for all tools

### Claude Code Integration
- ✅ Tool discovery via tools/list
- ✅ Proper content array response format
- ✅ Error handling with JSON-RPC error codes
- ✅ Concurrent tool execution support

### Remote Access
- ✅ mcp-proxy compatibility
- ✅ HTTP transport support
- ✅ Remote tool execution

## Recommendations

1. **For Claude Code Users:**
   - Use the latest MCP protocol version (2025-03-26) for best compatibility
   - Configure proper environment variables for optimal performance
   - Use remote setup via mcp-proxy for distributed environments

2. **For Developers:**
   - All tools now have proper titles and annotations for better UX
   - Error messages are Claude Code friendly with proper JSON-RPC codes
   - Schema validation ensures type safety

## Test Environment Details

- **Test Framework:** Mocha
- **Test Coverage:** Protocol, Schema, Execution, Remote Integration
- **Test Duration:** $(date)
- **Platform:** $(uname -s) $(uname -r)
