## Why This MCP Server?

Most ServiceNow MCP integrations are **read-only** and support a handful of tables. This one gives your AI assistant **full access** to the ServiceNow platform:

| Feature | Others | @onlyflows/servicenow-mcp |
|---------|--------|--------------------------|
| Query records | ✅ | ✅ |
| Create records | ❌ | ✅ |
| Update records | ❌ | ✅ |
| Delete records | ❌ | ✅ (with safety confirm) |
| Bulk operations | ❌ | ✅ (dry-run by default) |
| Aggregations (COUNT/AVG/MIN/MAX/SUM) | ❌ | ✅ |
| Table schema introspection | ❌ | ✅ |
| CMDB relationship traversal | ❌ | ✅ (recursive, configurable depth) |
| Instance health monitoring | ❌ | ✅ (version, nodes, jobs, stats) |
| Attachment management | ❌ | ✅ (list, upload, download) |
| System log queries | ❌ | ✅ |
| Code search across artifacts | ❌ | ✅ |
| Table/app/plugin discovery | ❌ | ✅ |
| ATF test execution | ❌ | ✅ |
| Natural language interface | ❌ | ✅ |
| Background scripts | ❌ | ✅ (with Playwright) |
| **Total tools** | **1–3** | **17** |

## Environment Variables

| Variable | Required | Default | Description |
|----------|----------|---------|-------------|
| `SN_INSTANCE` | ✅ | — | Instance URL (e.g. `https://yourinstance.service-now.com`) |

## Usage Examples

Once connected, your AI assistant can:

**Query incidents:**
> "Show me all P1 incidents assigned to the Network team"

**Create a record:**
> "Create an incident for VPN outage affecting 50 users, P2, assign to Network Operations"

**Aggregate data:**
> "How many incidents are there grouped by priority?"

**Check health:**
> "Run a health check on our ServiceNow instance"

**CMDB traversal:**
> "Show all upstream dependencies for the email-server-01 CI"

**Schema introspection:**
> "What fields are on the change_request table?"

**Code search:**
> "Find all business rules that reference GlideRecord('incident')"

**ATF testing:**
> "Run ATF test suite abc123 and wait for results"

## Safety Features

This server is designed for production use with multiple safety layers:

- **Delete operations** require explicit `confirm: true`
- **Batch operations** run in dry-run mode by default — shows match count without making changes
- **Bulk deletes** require both `confirm` and `force` flags
- **Background scripts** require `confirm` for destructive keywords (`deleteRecord`, `deleteMultiple`, etc.)
- **Natural language writes** require `execute: true` (reads execute immediately)
