feat: Bulk Import Tools modal wiring #737

[vk-playground]

Summary

Part 1 for the Bulk Import Tools feature. This PR adds the modal wiring and UX for opening/closing the “+ Bulk Import Tools” dialog and uploading a JSON file. It does not implement the submit/import behavior yet; that will land in a follow-up PR.

Refs #737

What’s included

• New modal wiring in admin.js using existing helpers (safeGetElement, openModal, closeModal, AppState).
• Supports:
  • Open via #open-bulk-import
  • Close via #close-bulk-import, backdrop click, and Esc
  • Scroll-lock while open
  • JSON textarea/file input
  • clears #import-result on open/close
• Compatible with HTMX form submission in the modal (no-op for now; actual import handler comes next).

What’s not included in this PR

• Backend POST /admin/tools/import processing and return HTML/JSON responses
• HTMX success/error UX on submit
• Validation and result rendering

Affected UI IDs

• #open-bulk-import (trigger button)
• #bulk-import-modal (modal container; initially has hidden)
• #bulk-import-backdrop (backdrop element; click to close)
• #close-bulk-import (close button in the modal)
• #import-result (container where import results HTML will be injected later)

Manual test plan

1. Open Admin UI.
2. Click + Bulk Import Tools → modal opens, background scroll locks.
3. Press Esc → modal closes.
4. Re-open; click outside (backdrop) → modal closes.
5. Re-open; click Close → modal closes.
6. While open, the JSON textarea or file input is focused automatically.
7. Upload a JSON file → accepted (no submit action yet).

Risk / Compatibility

• UI-only change, no backend impact.
• Uses existing modal helpers; no new dependencies introduced.

Checklist

• Feature guarded to just modal wiring (no import behavior yet)
• Works in dark mode and respects Tailwind classes already in use
• Tested open/close via button, backdrop, Esc
• Clears #import-result between sessions
• Refs [Feature Request]: Bulk Tool Import #737 (does not close)

Bulk Import Tools - API Design Document

Overview

The bulk import feature allows users to import multiple tools at once via JSON, either pasted directly or uploaded as a file.

Data Flow

Frontend (Part 1 - Current PR)

1. User clicks "+ Bulk Import Tools" button
2. Modal opens with two input options:
   • Textarea for JSON paste (tools_json)
   • File input for JSON upload (tools_file)
3. User provides JSON data and clicks "Import Tools"
4. Form validates and prepares data for submission

Backend (Part 2 - To Be Implemented)

API Design Options

Option 1: Single JSON Field (Recommended)

Endpoint: POST /admin/tools/import

Request Format:

// FormData with single field containing JSON array
const formData = new FormData();
formData.append('tools', JSON.stringify(toolsArray));
// OR if file uploaded:
formData.append('tools_file', file);

Backend Processing:

async def admin_import_tools(request: Request, db: Session):
    form = await request.form()
    
    # Check for file upload first
    if 'tools_file' in form:
        file = form['tools_file']
        content = await file.read()
        tools_data = json.loads(content.decode())
    # Otherwise use direct JSON
    elif 'tools' in form:
        tools_data = json.loads(form['tools'])
    else:
        return JSONResponse({"success": False, "message": "No data provided"})
    
    # Validate and process each tool
    results = {"success": [], "failed": []}
    for tool_data in tools_data:
        try:
            # Map fields to match existing admin_add_tool expectations
            mapped_data = {
                "name": tool_data.get("name"),
                "url": tool_data.get("url"),
                "description": tool_data.get("description", ""),
                "request_type": tool_data.get("requestType", "SSE"),
                "integration_type": tool_data.get("integrationType", "MCP"),
                "headers": tool_data.get("headers", {}),
                "input_schema": tool_data.get("inputSchema", {}),
                # ... other fields
            }
            await tool_service.register_tool(db, mapped_data)
            results["success"].append(tool_data["name"])
        except Exception as e:
            results["failed"].append({
                "name": tool_data.get("name", "unknown"),
                "error": str(e)
            })
    
    return JSONResponse({
        "success": len(results["failed"]) == 0,
        "imported": len(results["success"]),
        "failed": len(results["failed"]),
        "details": results
    })

Option 2: Reuse Existing Endpoint (Not Recommended)

Submit each tool individually to existing /admin/tools endpoint.

• Pros: No new backend code needed
• Cons: N+1 requests, no transaction support, poor performance

Option 3: Separate Text/File Fields

Keep tools_json and tools_file as separate fields.

• Pros: Clear distinction between input methods
• Cons: More complex validation, duplicate processing logic

Frontend Implementation (Updated)

async function handleBulkImportSubmit(e) {
    e.preventDefault();
    
    const form = e.target;
    const formData = new FormData();
    
    // Get JSON from textarea or file
    const jsonText = form.querySelector('[name="tools_json"]').value;
    const fileInput = form.querySelector('[name="tools_file"]');
    
    let toolsData;
    if (fileInput.files.length > 0) {
        // File takes precedence
        const file = fileInput.files[0];
        formData.append('tools_file', file);
    } else if (jsonText.trim()) {
        // Validate JSON before sending
        try {
            toolsData = JSON.parse(jsonText);
            if (!Array.isArray(toolsData)) {
                throw new Error("JSON must be an array of tools");
            }
            formData.append('tools', jsonText);
        } catch (err) {
            showError(`Invalid JSON: ${err.message}`);
            return;
        }
    } else {
        showError("Please provide JSON data or upload a file");
        return;
    }
    
    // Show loading state
    const indicator = document.getElementById('bulk-import-indicator');
    indicator.style.display = 'flex';
    
    try {
        const response = await fetch(`${window.ROOT_PATH}/admin/tools/import`, {
            method: 'POST',
            body: formData
        });
        
        const result = await response.json();
        
        // Display results
        if (result.success) {
            showSuccess(`Successfully imported ${result.imported} tools`);
            // Close modal and refresh page after delay
            setTimeout(() => {
                closeModal('bulk-import-modal');
                window.location.reload();
            }, 2000);
        } else {
            showResults(result);
        }
    } catch (error) {
        showError(`Import failed: ${error.message}`);
    } finally {
        indicator.style.display = 'none';
    }
}

        }
      }
    }
  },

}

Validation Rules

1. Name validation:

   • Must be unique in database
   • Alphanumeric with underscores/hyphens only
   • Max 100 characters

2. URL validation:

   • Must be valid URI
   • For MCP: mcp:// protocol
   • For REST: http:// or https://

3. Request type validation:

   • Required for REST integration
   • Must be null/empty for MCP integration

4. Batch limits:

   • Maximum 200 tools per import
   • File size limit: 5MB

Error Handling

Response Format

{
  "success": false,
  "imported": 3,
  "failed": 2,
  "details": {
    "success": ["tool1", "tool2", "tool3"],
    "failed": [
      {
        "name": "tool4",
        "error": "Duplicate name"
      },
      {
        "name": "tool5", 
        "error": "Invalid URL format"
      }
    ]
  },
  "message": "Imported 3 of 5 tools. 2 failed validation."
}

UI Feedback

• Show progress for large imports
• Display detailed error messages for failures
• Allow retry of failed items only
• Option to download error report

Security Considerations

1. Input validation:

   • Sanitize all string inputs
   • Validate JSON schema strictly
   • Prevent injection attacks

2. Rate limiting:

   • Max 10 bulk imports per minute per user
   • Max 200 tools per import

3. Authorization:

   • Require admin authentication
   • Log all bulk import operations

Testing Strategy

1. Unit tests:

   • JSON parsing and validation
   • Field mapping logic
   • Error handling

2. Integration tests:

   • End-to-end import flow
   • Database transaction handling
   • Duplicate detection

3. UI tests:

   • Modal interactions
   • File upload handling
   • Error display

Migration Path

Since Part 1 is UI-only:

1. Current PR: Modal and form setup
2. Part 2: Backend endpoint implementation
3. Part 3: Progress indicators and advanced features

Recommendation

Use Option 1 with a single JSON field approach:

• Simpler API contract
• Easier to validate and test
• Better transaction support
• Cleaner error handling

The frontend should:

1. Validate JSON client-side before submission
2. Use tools field for pasted JSON
3. Use tools_file field for file uploads
4. Let backend handle the unified processing

💡 Best Practices Implemented

1. Progressive Enhancement - Works without JavaScript (form still submits)
2. Graceful Degradation - Handles missing DOM elements safely
3. Error Recovery - Per-tool errors don't fail entire batch
4. User Feedback - Clear messaging for all states
5. Performance - Rate limiting prevents abuse
6. Security - Input sanitization and validation
7. Accessibility - Keyboard navigation and ARIA labels

🐛 Issues Identified & Fixed During Implementation

Issue 1: Bulk Import Not Working ❌→✅

Problem: User reported "bulk import does nothing, no tools imported"
Root Cause: Conflicting JavaScript - inline script overriding proper form submission
Solution: Removed conflicting inline script, restored proper admin.js implementation

Issue 2: Tab Navigation Broken ❌→✅

Problem: All tabs after Tools (Resources, Prompts, Gateways, etc.) stopped working
Root Cause: Bulk import modal placed incorrectly in HTML structure, breaking page flow
Solution: Moved modal to page level, fixed HTML structure to match main branch

Issue 3: JavaScript Conflicts ❌→✅

Problem: Multiple DOMContentLoaded listeners causing initialization conflicts
Root Cause: Bulk import setup interfering with main initialization sequence
Solution: Integrated bulk import setup into main initialization, removed duplicates

Issue 4: Linting Failures ❌→✅

🔧 Final Implementation Architecture

Backend Flow

1. Request → Rate Limiter (10/min)
2. Feature Flag Check → 403 if disabled
3. Content-Type Detection → JSON body vs Form data
4. Input Parsing → File upload vs Form field vs JSON body
5. Validation Loop → ToolCreate schema per tool
6. Import Processing → tool_service.register_tool()
7. Response Assembly → Frontend-compatible format

Frontend Flow

1. User clicks "+ Bulk Import Tools"
2. Modal opens with dual input options
3. User enters JSON textarea OR uploads file
4. Client-side validation (JSON syntax, array check)
5. Form submission via AJAX to /admin/tools/import
6. Loading state with spinner
7. Results display (success/partial/failure)
8. Auto-refresh on success OR detailed error display

Security & Validation

• Authentication: JWT token required for all requests
• Rate Limiting: 10 requests per minute per IP address
• Input Validation: Full ToolCreate schema validation per tool
• Batch Limits: Maximum 200 tools per request

1. Progressive Enhancement - Works without JavaScript (form still submits)
2. Graceful Degradation - Handles missing DOM elements safely
3. Error Recovery - Per-tool errors don't fail entire batch
4. User Feedback - Clear messaging for all states
5. Performance - Rate limiting prevents abuse
6. Security - Input sanitization and validation
7. Accessibility - Keyboard navigation and ARIA labels

🐛 Issues Identified & Fixed During Implementation

Issue 1: Bulk Import Not Working ❌→✅

Problem: User reported "bulk import does nothing, no tools imported"
Root Cause: Conflicting JavaScript - inline script overriding proper form submission
Solution: Removed conflicting inline script, restored proper admin.js implementation

Issue 2: Tab Navigation Broken ❌→✅

Problem: All tabs after Tools (Resources, Prompts, Gateways, etc.) stopped working
Root Cause: Bulk import modal placed incorrectly in HTML structure, breaking page flow
Solution: Moved modal to page level, fixed HTML structure to match main branch

Issue 3: JavaScript Conflicts ❌→✅

Problem: Multiple DOMContentLoaded listeners causing initialization conflicts
Root Cause: Bulk import setup interfering with main initialization sequence
Solution: Integrated bulk import setup into main initialization, removed duplicates

Issue 4: Linting Failures ❌→✅

Problem: JavaScript formatting errors, HTML validation failures
Root Cause: Inconsistent indentation and extra HTML tags
Solution: Fixed JavaScript formatting, corrected HTML structure

🔧 Final Implementation Architecture

Backend Flow

1. Request → Rate Limiter (10/min)
2. Feature Flag Check → 403 if disabled
3. Content-Type Detection → JSON body vs Form data
4. Input Parsing → File upload vs Form field vs JSON body
5. Validation Loop → ToolCreate schema per tool
6. Import Processing → tool_service.register_tool()
7. Response Assembly → Frontend-compatible format

Frontend Flow

1. User clicks "+ Bulk Import Tools"
2. Modal opens with dual input options
3. User enters JSON textarea OR uploads file
4. Client-side validation (JSON syntax, array check)
5. Form submission via AJAX to /admin/tools/import
6. Loading state with spinner
7. Results display (success/partial/failure)
8. Auto-refresh on success OR detailed error display

Security & Validation

• Authentication: JWT token required for all requests
• Rate Limiting: 10 requests per minute per IP address
• Input Validation: Full ToolCreate schema validation per tool
• Batch Limits: Maximum 200 tools per request
• XSS Protection: All user input escaped with escapeHtml()
• File Security: Proper file parsing with encoding validation
