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.

What it costs to keep this loaded
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 | $0.00110 | $0.05303 |
| Opus 5.5 | $0.00044 | $0.02121 |
| Sonnet 5.5 | $0.00022 | $0.01061 |
| Haiku 4.5 | $0.00011 | $0.00530 |
Grade A, and why
servicenow-cmdb 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 4d 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 — 298 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ServiceNow CMDB Data Foundations
Audit the CMDB as a data model: explore CI classes, read raw relationships, assess CMDB health, investigate data quality, review the CSDM service taxonomy, and score CSDM conformance by stage. This is platform data work, read-only.
For conversational CI search, service topology and change impact, ServiceNow ships its own CMDB MCP server (with Otto for CMDB). It has no health, staleness, duplicate or CSDM conformance tools; that is what this skill covers. See references/cmdb-tables.md for CI classes, health KPIs, CSDM mappings and encoded query syntax, and references/csdm5.md for CSDM 5 stages and the conformance scores.
Tables and roles
| Tables | Readable with |
|---|---|
cmdb_ci and most CI classes, cmdb_rel_ci, service_offering, sn_getwell_csdm_score |
cmdb_read ("CMDB reader"); itil contains it. snc_read_only alone gets 403 on cmdb_ci and the scores |
cmdb_health_scorecard, cmdb_health_result, cmdb_health_metric, the health rules |
sn_cmdb_user (CMDB Workspace, read-only) or itil; cmdb_read alone is not enough |
Service classes such as cmdb_ci_service_business and cmdb_ci_service_technical |
Often a service or CMDB role beyond itil: expect 403 |
sys_db_object (class hierarchy) |
itil and many other roles; servicenow://cmdb/classes reads it for you |
cmn_location, cmdb_model, alm_hardware |
itil |
reconcile_duplicate_task (de-duplication tasks) |
Returned 0 rows to itil + snc_read_only on a developer instance: empty or hidden, the call can't tell which |
Add snc_read_only to keep the identity read-only. These are the read ACLs on a Brazil instance; yours may differ. Creating or updating CIs needs sn_cmdb_editor: since Zurich, itil no longer contains it.
When access is denied
- A 403 on a class or table means not assessable with this identity. Name it in the report as a gap, and keep going with the classes you can read.
- 0 rows from a class can mean the class is empty or that ACLs hide its rows. Don't report "no services" when the read might be filtered.
- Health and score tables stay empty until their scheduled jobs have run. Empty is not the same as healthy.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

servicenow-cmdb is a skill published in the GitHub repository jschuller/mcp-server-servicenow (26 stars, last pushed 3d ago), licensed MIT. It adds 110 tokens to every session and 5,303 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
