1. ✅ Connection Context Interface Created
   - File: mcp-server/src/connection-context.ts
   - Defines: projectPath, connectionFile, host/port/user/password/database

2. ✅ Executor Updated
   - File: mcp-server/src/executor.ts
   - Changes:
     • Added ConnectionContext import
     • Updated executeCommand() signature to accept context
     • Build environment with context variables
     • Set working directory from context.projectPath

3. ✅ MCP Server Tools Updated  
   - File: mcp-server/src/index.ts
   - Changes:
     • Added ConnectionContext import
     • Extended all tool schemas with __projectContext parameter
     • Extract context from tool arguments before passing to CLI

4. ✅ CLI Connection Resolution Updated
   - File: utils/connections.js
   - Changes:
     • Check for HANA_CLI_PROJECT_PATH env var
     • Check for direct connection via env vars
     • Change working directory to project path if provided

5. ✅ Build Successful
   - All TypeScript files compiled to JavaScript
   - Ready for use

How to Use:
═══════════════════════════════════════════════════════════

const result = await mcp.callTool('hana_tables', {
  schema: 'MY_SCHEMA',
  __projectContext: {
    projectPath: '/path/to/my/project',
    connectionFile: '.env'
  }
});

This will:
1. Change CLI working directory to /path/to/my/project
2. Look for /path/to/my/project/.env
3. Use that project's database connection
4. NOT use ~/.hana-cli/default.json
