Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02588 | $0.02588 |
| Opus 5.5 | $0.01035 | $0.01035 |
| Sonnet 5.5 | $0.00518 | $0.00518 |
| Haiku 4.5 | $0.00259 | $0.00259 |
Grade A, and why
cursorrules scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.
NEX MCP Server Rules — ServiceNow Platform Automation
You have access to the now-sdk-ext-mcp MCP server for ServiceNow platform operations. Use these rules when interacting with ServiceNow instances.
Authentication
Every tool accepts an optional instance parameter (auth alias). If omitted, the SN_AUTH_ALIAS environment variable is used. If neither is available, the tool returns an error.
Encoded Query Syntax
Most query tools accept a query parameter using ServiceNow encoded query format:
=,!=,>,<,>=,<=— comparisonsLIKE,STARTSWITH,ENDSWITH— string matchingIN,NOT IN— list membership:stateIN1,2,3ISEMPTY,ISNOTEMPTY— null checksINSTANCEOF— table hierarchy:sys_class_nameINSTANCEOFtask^— AND:active=true^priority=1^OR— OR:priority=1^ORpriority=2ORDERBY<field>/ORDERBYDESC<field>— sorting

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cursorrules is a cursor rule published in the GitHub repository sonisoft-cnanda/now-sdk-ext-mcp (16 stars, last pushed 13d ago), licensed MIT. It adds 2,588 tokens to every session, about $0.0104 per session on Opus 5.5. A static security scan graded it A with 0 findings.
