JSN — ServiceNow CLI

A command-line interface for ServiceNow. Type jsn and start working — no web UI needed.

Works standalone or with AI agents (Claude Code, OpenCode, Hermes, Cursor, Copilot).

Install

npm install -g @jacebenson/jsn

Node.js 18+. macOS, Linux, Windows.

The install also copies an AI agent skill file to ~/.agents/skills/servicenow/SKILL.md.

Quick Start

jsn setup                                    # Interactive first-time setup
jsn auth login https://dev12345.service-now.com
jsn incidents list --query "priority=1"      # Critical incidents

What It Does

jsn talks to the ServiceNow REST API. Read, create, update, delete — tickets, users, groups, records on any table. Inspect flows and business rules. Export update sets. Run background scripts.

Everything outputs JSON when piped, styled tables in a terminal.

# Core ticket work
jsn incidents list --query "active=true^priority=1"
jsn incidents INC0010001
jsn incidents create --description "Server down" --priority 1

# Admin tasks
jsn flows list                                # Interactive picker with pagination
jsn flows show "Assign Task"                  # Full flow detail
jsn rules list --query "collection=incident"
jsn updatesets set "My Feature"

# Generic table access
jsn records list --table incident --limit 50 --json | jq '.[].number'
jsn records create --table incident --data '{"short_description":"test"}'

# Script execution
jsn eval "gs.info('Hello World')"

Commands

Run jsn for the full grouped list. Commands are organized by ServiceNow domain:

Core — incidents, changes, requests, tasks, tickets

Automation — flows, actions, rules, scrapi, updatesets, eval, rest

Access — acls, roles, scopes, properties, privileges

User Experience — forms, lists, clientscripts, uipolicies, uiactions

Data — records, tables, columns, includes, import, logs, users, groups

Every command supports --json, --query, and --help.

Profiles

Switch between instances without re-authenticating.

jsn auth login https://dev12345.service-now.com
jsn profiles list
jsn profiles use dev12345
jsn profiles show

Output Formats
