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 | $0.02024 |
| Opus 5 | $0.00055 | $0.01012 |
| Sonnet 5 | $0.00022 | $0.00405 |
| Haiku 4.5 | $0.00011 | $0.00202 |
Grade A, and why
mcp-server-audit scanned grade A with 1 finding 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 8d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Auditing an MCP server
Start here — do not reach for a scanner first
node scripts/audit-live-mcp.mjs # production
node scripts/audit-live-mcp.mjs http://localhost:3001
Zero dependencies, node built-ins only, installs nothing. Exit 1 on any FAIL. It covers the machine-checkable half of what the popular third-party scanners check (§4). Everything it prints is measured, never inferred — that matters, because the most common failure in MCP auditing is a confident report about a server nobody actually connected to.
Baseline for mcp.hellogrowthcrm.com on 2026-08-31: 2 fail · 5 warn · 12 pass.
A new FAIL is a regression. Record the run in the audit report.
1. The checks a script cannot do — always do these by hand
The wire protocol can be perfect while the server confidently serves false information. This is where the real defects were found:
- Are the numbers true? Call
features_list,integrations_list,content_list_industries,pricing_get_plansand reconcile each against the codebase. On 2026-08-31 the server reported 630 integrations against 525 in the code, and a feature list of 58 against 232 screens / 135 catalogue entries / 99 public-catalog features. Nothing regenerates the mirror from the source of truth, so it drifts silently. - Do the URLs resolve?
curl -o /dev/null -w "%{http_code}"every URL the server emits. AsameAsentry published as an entity signal was returning 404 while a second field in the same payload held a working one. - Are pricing / compliance / residency claims sourced? These end up quoted
verbatim by AI assistants. Check against the canonical source, not against a
draft someone pasted. Real values live in
pricing_get_plansandcountries_list. - Is the freshness stamp moving? Payloads carry
synced_at. A stamp weeks old with no regeneration job is the same silent-rot failure as any generated file.
2. Traps specific to this server
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.

mcp-server-audit is a skill published in the GitHub repository MeruLocal/HelloGrowthCRMwebsite_MCP (0 stars, last pushed 5d ago), licensed MIT. It adds 110 tokens to every session and 2,024 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
