## ServiceNow MCP Server Setup

You have access to a ServiceNow MCP server (`servicenow-devtools-mcp`) that provides
100 tools for interacting with a ServiceNow instance.

### Installation

Run via uvx (no install required):
```
uvx servicenow-devtools-mcp
```

### Required Environment Variables

- SERVICENOW_INSTANCE_URL -- Full URL of the ServiceNow instance (e.g. https://dev12345.service-now.com)
- SERVICENOW_USERNAME -- ServiceNow user with admin or appropriate roles
- SERVICENOW_PASSWORD -- Password for the user above

### Optional Environment Variables

- MCP_TOOL_PACKAGE -- Which tools to load (default: "full"). See Tool Packages section for all 14 options.
- SERVICENOW_ENV -- Environment label: "dev" (default), "test", "staging", "prod". Write operations are blocked when set to "prod" or "production".
- MAX_ROW_LIMIT -- Max records per query (default: 100, max: 10000)
- LARGE_TABLE_NAMES_CSV -- Tables requiring date-bounded queries (default: syslog,sys_audit,sys_log_transaction,sys_email_log)
- SCRIPT_ALLOWED_ROOT -- When using artifact_write with script_path, constrains file reads to this directory tree (required for script_path). The file must be an existing regular UTF-8 file of <= 1 MB.

### Safety Guardrails

- Table deny list: sys_user_has_role, sys_user_grmember, and other sensitive tables are blocked
- Sensitive fields: password, token, secret fields are masked in responses
- Row limits: User-supplied limit parameters capped at MAX_ROW_LIMIT (default 100)
- Large tables: syslog, sys_audit, etc. require date-bounded filters
- Write gating: All write operations blocked when SERVICENOW_ENV contains "prod" or "production"
- Attachments: uploads accept `content_base64`; download tools return `content_base64`
- Mandatory field validation: record creation validates all required fields are present before submission
- Standardized responses: Tools return TOON-serialized envelopes with correlation_id, status, data, and optionally pagination and warnings

Environment Variables

Variable	Description	Default	Required
`SERVICENOW_INSTANCE_URL`	Full URL of your ServiceNow instance (must start with `https://`)	--	Yes
`SERVICENOW_USERNAME`	ServiceNow username (Basic Auth)	--	Yes
`SERVICENOW_PASSWORD`	ServiceNow password	--	Yes
`MCP_TOOL_PACKAGE`	Tool package to load (see Tool Packages)	`full`	No
`SERVICENOW_ENV`	Environment label (`dev`, `test`, `staging`, `prod`)	`dev`	No
`MAX_ROW_LIMIT`	Maximum rows returned per query (range: 1-10000)	`100`	No
`LARGE_TABLE_NAMES_CSV`	Comma-separated tables requiring date filters	`syslog,sys_audit,sys_log_transaction,sys_email_log`	No
`SCRIPT_ALLOWED_ROOT`	Root directory for `script_path` in artifact write tools	`""` (disabled)	Yes (when using `script_path`)
`SENTRY_DSN`	Sentry DSN for error reporting (enables Sentry when set)	`""`	No
`SENTRY_ENVIRONMENT`	Sentry environment label	Falls back to `SERVICENOW_ENV`	No

The server reads from .env and .env.local files automatically (.env.local takes precedence).

Sentry Error Tracking

Opt-in error tracking designed for MCP servers. Since MCP servers run as child processes of AI agents via stdio, the user never sees stdout or stderr - Sentry provides the primary way to get error visibility in production.

Install with Sentry support

uv pip install "servicenow-devtools-mcp[sentry]"

Enable error tracking

# Required - provide a Sentry DSN to activate
SENTRY_DSN=https://your-key@o123.ingest.sentry.io/456

# Optional - override environment label (defaults to SERVICENOW_ENV)
SENTRY_ENVIRONMENT=production

Variable	Description	Default	Required
`SENTRY_DSN`	Sentry DSN for error reporting	`""` (disabled)	No
`SENTRY_ENVIRONMENT`	Sentry environment label	Falls back to `SERVICENOW_ENV`	No

What gets captured

Tool errors - every unhandled exception in tool execution, with tool name and correlation ID as tags
HTTP errors - ServiceNow API failures with status code, method, and URL as structured context
Infrastructure failures - broken tool group imports, persistent sys_choice fetch failures, TOON encoding bugs

Graceful degradation

Without sentry-sdk installed: zero overhead, all functions no-op
With package installed but no SENTRY_DSN set: no client initialized
With package installed and SENTRY_DSN set: full error capture active

Performance monitoring is enabled in Sentry with traces_sample_rate=1.0 (100% sampling) to capture full performance telemetry for this MCP server. Since MCP servers are single-user stdio processes, this is unlikely to cause ingest overhead. For high-throughput deployments, consider reducing the sample rate in code.

`knowledge_management`	6	Knowledge base tools with attachment writes
`service_catalog`	6	Service catalog tools with attachment writes
`core_readonly`	4	Read-only core tools (table, record, attachment, metadata)
`none`	0	Only `list_tool_packages` -- minimal/testing

Custom Packages

You can also specify a comma-separated list of tool group names to create a custom package:

MCP_TOOL_PACKAGE="table,record,debug,domain_incident"

Readonly-style packages include only attachment. Write-capable packages include both attachment and attachment_write.

Available tool groups: table, record, attachment, record_write, attachment_write, metadata, artifact_write, changes, debug, investigations, documentation, workflow, flow_designer, testing, domain_incident, domain_change, domain_problem, domain_cmdb, domain_request, domain_knowledge, domain_service_catalog.

Safety & Policy

The server includes built-in guardrails that are always active:

Table deny list -- Sensitive tables like sys_user_has_role, sys_user_grmember, and 6 others are blocked from queries
Sensitive field masking -- Fields whose names match patterns like password, token, secret, credential, api_key, or private_key are masked with the literal value ***MASKED*** in responses
Row limit caps -- User-supplied limit parameters are capped at MAX_ROW_LIMIT (default 100, max 10000). If a larger value is requested, the limit is reduced and a warning is included in the response
Large table protection -- Tables listed in LARGE_TABLE_NAMES_CSV require date-bounded filters in queries to prevent full-table scans
Write gating -- All write operations (record_write tools and domain create/update tools) are blocked when SERVICENOW_ENV contains "prod" or "production". There is no override - use a sub-production instance for write operations
Query safety -- Structured query validation with identifier checks and internal query limits
Standardized responses -- Every tool returns a TOON-serialized envelope with correlation_id, status, and data, and may include pagination and warnings when applicable

Example Prompts

Here are some real-world prompts you can use with an AI agent that has this MCP server connected:

Describe the incident table and show me all the business rules that fire on it.

List all P1 incidents from the last week and show me who resolved them.

Trace the full lifecycle of INC0010042 -- show me every field change, comment, and log entry.

Inspect update set "Q1 Release" and generate release notes. Flag any risky changes.

Run the stale_automations investigation and explain the top findings.

Find all scripts that reference the "cmdb_ci_server" table and check them for anti-patterns.

Create a new incident with priority 1 and short description "Server outage". Show me a preview first.

Show me the performance bottlenecks investigation and explain any slow transactions found.

List all open change requests and show me the tasks for CHG0010023.

Search the knowledge base for "VPN setup" and update the article with the new server address.

Browse the service catalog for laptop requests and show me the available options.

Check CMDB health and show me the relationships for our production database server.
