Claude Desktop Integration

Prerequisites

1. Get Cisco API Credentials:

2. Install Claude Desktop:

Step-by-Step Setup

1. Locate Claude Desktop Config File:

2. Create or Edit the Config File:

{
     "mcpServers": {
       "cisco-support": {
         "command": "npx",
         "args": ["-y", "mcp-cisco-support"],
         "env": {
           "CISCO_CLIENT_ID": "your_client_id_here",
           "CISCO_CLIENT_SECRET": "your_client_secret_here",
           "SUPPORT_API": "bug,product"
         }
       }
     }
   }

> Note: The `-y` flag automatically accepts package installation, which is required for Claude Desktop since it runs in the background without user interaction.

Optional Environment Variables:

Configure which APIs to enable with `SUPPORT_API`:

Product Autocomplete (optional, requires `SUPPORT_API` to include `product`):

"env": {
     "CISCO_CLIENT_ID": "your_client_id_here",
     "CISCO_CLIENT_SECRET": "your_client_secret_here",
     "SUPPORT_API": "bug,product",
     "CISCO_WEB_COOKIE": "JSESSIONID=...; OptanonConsent=..."
   }

See the Product Autocomplete section for setup instructions.

3. Replace Your Credentials:

4. Restart Claude Desktop:

Verification

After setup, you should be able to:

1. Ask Claude about Cisco bugs:

"Search for bugs related to memory leaks in Cisco switches"

2. Get specific bug details:

"Get details for Cisco bug CSCab12345"

3. Search by product:

"Find bugs affecting Cisco Catalyst 3560 switches"

Example Usage in Claude Desktop

Once configured, you can ask Claude questions like:

• Basic Bug Search:
  • "Search for recent bugs related to 'crash' in Cisco products"
  • "Find open bugs with severity 1 or 2"
  • "Show me bugs modified in the last 30 days"

• Product-Specific Searches:
  • "Find bugs for product ID C9200-24P"
  • "Search for bugs in Cisco Catalyst 9200 Series affecting release 17.5.1"
  • "Show bugs fixed in software release 17.5.2"

• Bug Details:
  • "Get full details for bug CSCab12345"
  • "Show me information about bugs CSCab12345,CSCcd67890"

• Advanced Filtering:
  • "Find resolved bugs with severity 3 modified after 2023-01-01"
  • "Search for bugs in 'Cisco ASR 9000 Series' sorted by severity"
  • "Can you show me all the cisco bugs in the last 30 days for the product Cisco Unified Communications Manager (CallManager)?" (uses keyword search)
  • "Find bugs for Cisco Unified Communications Manager affecting releases 14.0 and 15.0" (uses product series search)

Claude will use the appropriate MCP tools to fetch real-time data from Cisco's Bug API and provide comprehensive responses with the latest information.

MCP Prompts

The server includes 10+ specialized prompts for guided Cisco support workflows:

• 🔍 cisco-high-severity-search - Search high-severity bugs by product or serial number
• 🚨 cisco-incident-investigation - Investigate symptoms and errors
• 🔄 cisco-upgrade-planning - Research issues before upgrades
• 🔧 cisco-maintenance-prep - Prepare for maintenance windows
• 🔒 cisco-security-advisory - Research security vulnerabilities
• ⚠️ cisco-known-issues - Check for software release issues
• 📋 cisco-case-investigation - Investigate support cases
• ⏰ cisco-lifecycle-planning - End-of-life planning
• 🎯 cisco-smart-search - Intelligent search with automatic refinement
• ✨ cisco-interactive-search - Interactive search with elicitation

Serial Number Support: Most prompts now accept either a product name OR a serial number. When you provide a serial number (e.g., "SAL09232Q0Z"), the server automatically looks up the product details and uses them for the search. This makes it easy to investigate issues when you have a device serial number but don't know the exact product model.

Each prompt provides structured investigation plans and expert recommendations.

Interactive Search with Elicitation

The cisco-interactive-search prompt demonstrates MCP's elicitation feature, allowing the server to dynamically request additional information from users during tool execution. This makes searches more natural and helps gather missing parameters without restarting requests.

Example Usage:

Use the "cisco-interactive-search" prompt with:
- initial_query: "memory leak"
- use_elicitation: true

See **examples/elicitation-example.md for detailed usage examples and ⚡ MCP Prompts** for complete prompt documentation.

🔍 MCP Resources - Product Autocomplete

The server exposes Cisco data as MCP Resources for direct client access. This includes a new Product Autocomplete feature that lets you search Cisco's internal product catalog using your browser session cookie.

Available Product Resources

When `SUPPORT_API` includes `product`, the following resources are available:

Resource Templates (dynamic URIs):

• `cisco://products/{product_id}` - Get product details by ID (e.g., C9300-24P, ISR4431)
• `cisco://products/autocomplete/{search_term}` - ✨ NEW: Search product catalog by name or model

Static Resources:

• `cisco://products/catalog` - Product catalog overview
• `cisco://products/autocomplete-help` - ✨ NEW: Setup instructions for product autocomplete

Product Autocomplete Setup

The product autocomplete feature requires your Cisco.com session cookie to access Cisco's internal API.

Quick Setup:

1. Log in to Cisco:

2. Extract Your Cookie:

3. Set Environment Variable:

export CISCO_WEB_COOKIE="JSESSIONID=...; OptanonConsent=...; ..."

4. Query Products:

cisco://products/autocomplete/4431
   cisco://products/autocomplete/catalyst
   cisco://products/autocomplete/ASA

Cookie Lifecycle:

• Typical Validity: 24 hours
• Recommended Refresh: Daily before heavy use
• Expiration Signs: 401/403 errors, "Cookie expired" messages

For detailed setup instructions, query the help resource:

cisco://products/autocomplete-help

Example Response

Query: `cisco://products/autocomplete/4431`

{
  "autoPopulateHMPProductDetails": [{
    "parentMdfConceptId": 286281708,
    "parentMdfConceptName": "Cisco 4000 Series Integrated Services Routers",
    "mdfConceptId": 284358776,
    "mdfConceptName": "Cisco 4431 Integrated Services Router",
    "mdfMetaclass": "Model"
  }]
}

Security Best Practices

• ✅ Never commit cookies - they're like passwords
• ✅ Use .env file - already in .gitignore
• ✅ Refresh regularly - cookies expire after ~24 hours
• ✅ Monitor activity - check your Cisco account
• ✅ Use dedicated account - not your primary login

Usage in Claude Desktop

Ask Claude:

• "Show me the help for product autocomplete"
• "Search for Cisco product 4431 using autocomplete"
• "What is the full name of product ISR4431?"
• "Find products matching 'catalyst switch'"

See **docs/PRODUCT_AUTOCOMPLETE_SOLUTIONS.md for implementation details and docs/CISCO_COOKIE_ANALYSIS.md** for cookie lifecycle information.

⚠️ Smart Bonding Customer API (EXPERIMENTAL/UNTESTED)

The server includes experimental support for Cisco's Smart Bonding Customer API for ticket management and problem code classification. This feature is UNTESTED and requires special credentials obtained through your Cisco Account Manager.

Smart Bonding Features

Available Tools (8 total):

• `get_smart_bonding_tsp_codes` - Retrieve TSP (Technology, Sub-Technology, Problem Code) details for ticket classification
• `pull_smart_bonding_tickets` - Retrieve ticket updates from Cisco that haven't been pulled yet
• `create_smart_bonding_ticket` - Create a new support ticket (returns upload credentials in response)
• `update_smart_bonding_ticket` - Add work notes and update ticket status
• `upload_file_to_smart_bonding_ticket` - Upload files using credentials from ticket creation (HTTPS PUT to cxd.cisco.com)
• `escalate_smart_bonding_ticket` - Escalate critical issues to Cisco
• `resolve_smart_bonding_ticket` - Mark tickets as resolved with resolution notes
• `close_smart_bonding_ticket` - Close completed tickets with diagnosis and solution

File Upload Process

Smart Bonding uses a separate upload mechanism from the REST API:

1. Create ticket → Response includes upload credentials (Field80-82)

2. Save credentials → Cannot be retrieved later!

3. Upload files → Use `upload_file_to_smart_bonding_ticket` tool or curl

4. 72-day expiration → Token expires 72 days after creation

Upload credentials provided in ticket creation response:

• Field80: Upload domain (e.g., cxd.cisco.com)
• Field81: Authentication token (password)
• Field82: Token expiration timestamp

Files cannot be modified after upload - submit new files for corrections.

Authentication Differences

Smart Bonding API uses a different authentication system than standard Cisco Support APIs:

Configuration

1. Obtain Credentials - Contact your Cisco Account Manager to request Smart Bonding API access

2. Set Environment Variables:

export SMART_BONDING_CLIENT_ID=your_smart_bonding_client_id
   export SMART_BONDING_CLIENT_SECRET=your_smart_bonding_client_secret
   export SMART_BONDING_ENV=production  # or 'staging' for test environment
   export SUPPORT_API=smart_bonding     # Enable Smart Bonding API

3. Use Smart Bonding Tools:

Important Notes

• ⚠️ EXPERIMENTAL/UNTESTED - This implementation has not been tested with live Smart Bonding credentials
• ⚠️ Separate Credentials Required - Smart Bonding uses different OAuth2 credentials than standard Support APIs
• ⚠️ Not Included in `SUPPORT_API=all` - Must be explicitly enabled with `SUPPORT_API=smart_bonding`
• ⚠️ Special Access Required - Contact Cisco Account Manager for credential provisioning
• Base URLs differ for staging vs production environments
• Supports correlation IDs for end-to-end request traceability

Example Usage

# With Claude Desktop - add to claude_desktop_config.json
{
  "mcpServers": {
    "cisco-smart-bonding": {
      "command": "npx",
      "args": ["-y", "mcp-cisco-support"],
      "env": {
        "SMART_BONDING_CLIENT_ID": "your_id",
        "SMART_BONDING_CLIENT_SECRET": "your_secret",
        "SMART_BONDING_ENV": "production",
        "SUPPORT_API": "smart_bonding"
      }
    }
  }
}

cp config/oauth-clients.example.json config/oauth-clients.json
cp config/oauth-secrets.example.json config/oauth-secrets.json

# 2. Edit config/oauth-clients.json to configure your clients
# 3. Add client secrets to config/oauth-secrets.json (optional, for confidential clients)

# 4. Start server in OAuth 2.1 mode
AUTH_TYPE=oauth2.1 npm run oauth:start
# or for development with hot reload:
npm run oauth:dev

Configuration Files

config/oauth-clients.json - Client configuration (can be version controlled):

{
  "clients": [
    {
      "client_id": "mcp_inspector_dev",

• Native fetch: Uses Node.js native fetch instead of external libraries
• Token Management: 12-hour token validity with 30-minute refresh margin
• Error Handling: Comprehensive error handling with proper MCP error responses
• Security: Helmet security headers, CORS support, input validation
• Logging: Structured JSON logging with timestamps

Performance Considerations

• Token caching reduces API calls
• Pagination limits results to 10 per page
• SSE heartbeat every 30 seconds keeps connections alive
• Request timeout set to 30 seconds

Security Notes

• Never commit `.env` file to version control
• Use environment variables for all secrets
• Review Cisco API usage limits and terms
• Monitor logs for suspicious activity

API Reference

Authentication

• OAuth2 URL: `https://id.cisco.com/oauth2/default/v1/token`
• Grant Type: `client_credentials`
• Token Validity: 12 hours
• Auto-refresh: 30 minutes before expiry

Bug API Base URL

• Base URL: `https://apix.cisco.com/bug/v2.0`

MCP Protocol

The server implements the Model Context Protocol with these methods:

• `initialize`: Initialize MCP connection
• `tools/list`: List available tools
• `tools/call`: Execute a tool

Example MCP message:

{
  "jsonrpc": "2.0",
  "id": "1",
  "method": "tools/call",
  "params": {
    "name": "search_bugs_by_keyword",
    "arguments": {
      "keyword": "memory leak",
      "status": "open"
    }
  }
}

Health Monitoring

The server provides a comprehensive health check endpoint:

curl http://localhost:3000/health

Response includes server status, OAuth2 token status, memory usage, uptime, and active connections.

Testing

Comprehensive Jest-based testing framework with:

• ✅ 46/46 tools tested - All MCP tools across 8 APIs
• ✅ Mock & Real API testing - Unit tests with mocks + integration tests with live APIs
• ✅ Individual tool testing - Standalone test runner for development

# Run all tests
npm test

# Test with real API credentials
CISCO_CLIENT_ID=your_id CISCO_CLIENT_SECRET=your_secret npm test

# Test individual tools
npm run test:tool search_bugs_by_keyword
