HANA Developer Command Line Interface

# Knowledge Base Integration Implementation

## Summary

The hana-cli MCP Server has been enhanced with comprehensive documentation integration. All project markdown files are now aggregated into a knowledge base that provides AI assistants with direct access to project documentation, best practices, security guidelines, and technical reference material.

## Files Modified

### 1. mcp-server/src/readme-knowledge-base.ts (NEW)

Comprehensive knowledge aggregation system with:

- **Connection Resolution Guide**: 7-step process for finding database credentials
- **Standard Parameters**: Organized by command category (data-manipulation, batch-operations, list-inspect)
- **Security Guidelines**: Connection security, SQL injection protection, best practices
- **Naming Conventions**: Parameter naming patterns, alias rules, usage examples
- **Project Structure**: Overview of all folders and key resources
- **Documentation Resources**: Links to all markdown files in the project

### 2. mcp-server/src/index.ts (MODIFIED)

Added knowledge base integration:

- Imported ReadmeKnowledgeBase module
- Registered 6 new MCP tools
- Added handler functions for each knowledge base tool

### 3. mcp-server/README.md (ENHANCED)

Added documentation for:

- Knowledge base integration overview
- 6 new knowledge base tools
- Usage examples and scenarios
- Architecture updates
- Version 1.202602.4 section

## New MCP Tools

The following six tools are now available:

1. **hana_connection_guide** - Shows how the tool finds database credentials (7-step process)

2. **hana_standard_parameters** - Standardized parameters for command categories with aliases and defaults

3. **hana_security_guide** - Comprehensive security best practices and guidelines

4. **hana_best_practices** - Parameter naming conventions, patterns, and usage examples

5. **hana_project_structure** - Project organization and key resources

6. **hana_docs_search** - Full-text search across all project documentation

## Benefits

- AI assistants have direct access to comprehensive project documentation
- Connection troubleshooting without external resources
- Parameter learning with standardized conventions
- Security awareness built into the interface
- Project navigation and resource discovery
