# MCP Resources Summary

## Implementation Complete

MCP Resources have been successfully implemented for the ServiceNow MCP server.

## Files Created

1. **`/src/resources.js`** - Resource handlers implementation
2. **`/docs/RESOURCES_IMPLEMENTATION.md`** - Complete documentation

## Integration Required

Add to `/src/mcp-server-consolidated.js`:

```javascript
import { createResourceHandlers } from './resources.js';

// After loading tableMetadata:
const { listResources, readResource } = createResourceHandlers(
  serviceNowClient,
  configManager,
  tableMetadata
);

// Replace existing resource handlers with:
server.setRequestHandler(ListResourcesRequestSchema, listResources);
server.setRequestHandler(ReadResourceRequestSchema, async (request) => {
  const { uri } = request.params;
  return await readResource(uri);
});
```

## Resource URIs Implemented

### Global Resources
- `servicenow://instances` - All configured instances
- `servicenow://tables` - All available tables with metadata

### Instance Resources
- `servicenow://{instance}/info` - Instance info & capabilities
- `servicenow://{instance}/incidents` - Active incidents (25)
- `servicenow://{instance}/incidents/{number}` - Specific incident
- `servicenow://{instance}/users` - Active users (50)
- `servicenow://{instance}/update-sets` - Update sets in progress (25)
- `servicenow://{instance}/update-sets/{sys_id}` - Update set contents & breakdown
- `servicenow://{instance}/groups` - User groups (50)
- `servicenow://{instance}/change-requests` - Active change requests (25)

## Key Features

1. **Multi-Instance Support** - Automatic instance routing
2. **Metadata Enrichment** - All responses include timestamp, instance, count
3. **Cacheable** - Read-only with timestamps for client caching
4. **Error Handling** - Clear error messages with suggestions
5. **Performance Optimized** - Field selection, default limits
6. **Update Set Inspection** - Detailed component breakdown by type

## Example Response Format

```json
{
  "metadata": {
    "timestamp": "2025-10-06T12:00:00.000Z",
    "instance": "dev",
    "description": "Active incidents from dev",
    "record_count": 15
  },
  "data": [
    {
      "number": "INC0012345",
      "short_description": "Server down",
      "state": "1",
      "priority": "1",
      "assigned_to": {"value": "abc123", "display_value": "John Doe"},
      "sys_created_on": "2025-10-05 14:23:15"
    }
  ]
}
```

## Testing

Use MCP Inspector to test:

```bash
npx @modelcontextprotocol/inspector node src/stdio-server.js

# Commands:
resources/list
resources/read servicenow://dev/info
resources/read servicenow://dev/incidents
resources/read servicenow://dev/update-sets/abc123
```
