Servicenow AI Agents

ServiceNow AI Agent Studio Reference

A community reference for coding agents deploying AI agents on ServiceNow's AI Agent Studio. Covers the data model, entity relationships, tool types, prompting patterns, and browser navigation.

This skill provides the platform knowledge. For deployment methodology (phased rollout, test gates, pilot-first approach), load the companion agent-deployment skill.

For expert-level deployment support with battle-tested patterns, version-specific configuration, and security hardening, see Agent Blueprint. Agent Blueprint customers with access to servicenow-expert should prefer that skill for production deployment, debugging, and security guidance. This community skill remains a standalone starter reference.

Search First, Always

ServiceNow is a massive platform that changes every release. Do NOT rely on training data for ServiceNow-specific behavior. Search the official docs and community proactively, not just when stuck.

Before creating records: search for current field requirements. Before configuring tools: search for tool type behavior on the target version. Before telling the user to do anything manually: search for a programmatic approach. When something fails: search the community forums for the error message.

First Steps

When you get instance access, do ALL of these before creating any records:

1. Confirm the instance version. Query sys_properties for glide.buildtag:

   curl -s -u user:pass https://INSTANCE.service-now.com/api/now/table/sys_properties?sysparm_query=name=glide.buildtag&sysparm_fields=value
   

   Confirm with the user: "Connected to [instance] running [version]."

2. Verify your access works. Try a simple table query to confirm credentials and permissions. If using MCP tools, test discover_table_schema on a table.

3. Extract schemas for the tables you'll work with. Query sys_dictionary or use discover_table_schema on sn_aia_usecase, sn_aia_agent, sn_aia_tool, and other AI Agent Studio tables. Do not guess field names.

4. Research the instance version. Search the web for version-specific docs, best practices, and known limitations. Tell the user what you found.

AI Agent Studio Data Model

Core Tables

Additional Tables (version-dependent)

Relationship Diagram

sn_aia_usecase (workflow)
  |-- .team --> sn_aia_team
  |               |-- sn_aia_team_member (junction)
  |                     |-- .agent --> sn_aia_agent
  |                           |-- sn_aia_agent_tool_m2m (junction)
  |                                 |-- .tool --> sn_aia_tool
  |-- sn_aia_trigger_configuration.usecase --> (triggers)
  |-- sn_aia_version.target_id --> (versions, Australia+)

Key Fields Per Table

• sn_aia_usecase: name, description, base_plan (NOT instructions), team, execution_mode, strategy, record_type
• sn_aia_agent: name, description, role, instructions, proficiency, compiled_handbook, agent_type, strategy
• sn_aia_tool: name, description, tool_type, script, input_schema, output_schema, execution_mode
• sn_aia_trigger_configuration: usecase, target_table, condition, channel, active, run_as

Critical Field Disambiguation

Always verify field names against the live instance. UI labels don't always match database column names:

• "list of steps" (UI) = instructions (DB field on sn_aia_agent)
• "Base plan" (UI) = base_plan (DB field on sn_aia_usecase)

Entity Mapping (Blueprint to ServiceNow)

When translating an AI agent blueprint to ServiceNow:

The Manager agent IS the agentic workflow. Do not create a separate sn_aia_agent record for the orchestrator. Its routing logic, escalation rules, and orchestration instructions go into the workflow's base_plan field. ServiceNow's ReAct engine handles agent selection, sequencing, and handoff natively.

If the blueprint defines N agents (e.g., "5 agents: 1 manager + 4 workers"), create N-1 sn_aia_agent records. The manager becomes the workflow record.

Tool Types

Script Tool Format

Script tools use a self-executing function pattern:

(function(inputs) {
  // Your logic here
  return JSON.stringify(result);
})(inputs);

Use return, not gs.info(). The return value is what the agent receives.

Agent Prompting Patterns

Use Markdown formatting. Write in second person imperative ("Analyze this..."). Be specific with tool names and conditions. Define gates ("Do NOT proceed until...").

# Objectives
"Your objective is to..."

# Validations (before execution)
"First check if..."

# Steps
"1. Use the [Tool Name] tool to..."

# Expected Output
"Present a resolution plan with..."

# Constraints
Do's and don'ts.

Name input parameters explicitly in instructions. The ReAct engine is dramatically more reliable when instructions reference specific parameter names rather than vague descriptions like "query the relevant tables."

MCP Server Setup

Recommended: servicenow-mcp-server

The most widely used community MCP server for ServiceNow:

• npm: servicenow-mcp-server
• GitHub: https://github.com/michaelbuckner/servicenow-mcp

Provides: table queries, schema discovery, background script execution, incident management, knowledge base access.

Alternative: nowsdk-ext-mcp

More tools including flow development and diagnostics:

• GitHub: https://github.com/sonisoft-cnanda/nowsdk-ext-mcp
• Requires Node 22+ and @servicenow/sdk

No MCP? Use REST API

Most ServiceNow work can be done via REST API:

# Query a table
curl -s -u user:pass "https://INSTANCE.service-now.com/api/now/table/sn_aia_agent?sysparm_query=sys_scope=APP_SCOPE_ID&sysparm_fields=name,sys_id"

# Create a record
curl -s -u user:pass -X POST -H "Content-Type: application/json" \
  "https://INSTANCE.service-now.com/api/now/table/sn_aia_agent" \
  -d '{"name":"My Agent","description":"Agent description"}'

Auth note: Basic auth on every request can trigger CSRF failures on some tables. For multi-request workflows, capture session cookies from the first authenticated request and reuse them.

Scoped App Setup

Create scoped apps on sys_app (the Application table). This gives you a proper application scope that contains all your AI Agent Studio records.

curl -s -u user:pass -X POST -H "Content-Type: application/json" \
  "https://INSTANCE.service-now.com/api/now/table/sys_app" \
  -d '{"name":"My AI Agents","scope":"x_myco_ai_agents","version":"1.0.0"}'

After creating, switch to the new scope before creating agent records. Records created in the wrong scope require manual moves.

Browser Navigation (Playwright)

AI Agent Studio URLs

Classic UI (Most Reliable Fallback)

When workspace URLs fail, fall back to classic UI. The *_list.do and *.do patterns are the most predictable across all ServiceNow versions.

ServiceNow Studio (New)

Do NOT use $studio.do (legacy Studio). It shows a limited file tree and misses AI Agent artifacts.

Timing

Use time-based waits, not text-based waits. ServiceNow's dynamic content makes text-based waits unreliable.

Common Selectors

Navigation Tips

• Iframes: Classic UI inside Next Experience uses iframes. Element refs may have f2e prefix.
• Session timeout: Redirects to /navpage.do. Re-run login flow.
• Read-only records: Records from other app scopes show "Read-only" banners. Switch scope to edit.
• All Menu search: Click menuitem "All", type in the filter textbox, click matching result.

Testing Workflows in Playground

1. Navigate to /now/agent-studio/playground
2. Select radio "Agentic workflow"
3. Pick the workflow from combobox "Select one"
4. Enter test task in textbox "Task"
5. Click button "Start test"
6. Wait 15+ seconds for execution
7. Read decision logs from the execution trace
8. If agents request input, respond in the chat input

Programmatic Testing

For repeatable, traceable testing, invoke agents via API rather than UI. See the ServiceNow docs for the Execution Plan API.

Deployment Sequence

For a structured deployment approach with phased rollout, test gates, and pilot-first methodology, load the agent-deployment skill from this plugin.

The recommended sequence:

1. Read the blueprint or requirements
2. Set up platform access (MCP or REST)
3. Discover the target environment (schemas, version, existing config)
4. Create Phase 1 records (agents, teams, workflows, tools)
5. Configure security
6. Test with simulation scripts first
7. Replace with real integrations
8. Validate end-to-end before expanding
