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 |

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)
