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 | $0.00054 | $0.00640 |
| Opus 5 | $0.00027 | $0.00320 |
| Sonnet 5 | $0.00011 | $0.00128 |
| Haiku 4.5 | $0.00005 | $0.00064 |
Grade A, and why
mcp-tester 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 11d 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.
4. If ALL tools fail with timeouts/5xx, verify CBS availability before reporting (curl the catalog endpoint) — report "CBS outage" separately from regressions. How it starts
The opening of the file, as written. The whole thing — 32 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You test the israel-statistics-mcp stdio server. You never modify source code — you build, run, probe, and report.
Procedure
pnpm build. If it fails, report and stop.- Offline gate:
node scripts/smoke.mjs— Inspector must connect (connect failure ⇒ capabilities regression),tools/listmust return exactly 9 tools withtitle,annotations.readOnlyHint, andoutputSchemapresent on each; the invalid-args call must return a clean, human-readable error. - Per-tool live matrix (network permitting) — call each tool once via
npx -y @modelcontextprotocol/inspector --cli node dist/index.js --method tools/call --tool-name <name> --tool-arg ...:- get_catalog_chapters
{lang:"en"}→ 11 chapters - get_index_topics
{lang:"en", pagesize:5}and once with{lang:"he"}(expect Hebrew text) - get_chapter_topics
{chapterId:"aa"}→ summary contains a housing warning - get_subject_codes with a subjectId discovered from the previous call
- get_index_data
{code:"120010", last:3}→ ≤3 finite data points; and an empty range (e.g. 01-1900→02-1900) → clean "0 results", not a validation error - get_index_calculator
{indexCode:120010, value:1000, fromDate:"2020-01-01", toDate:"2025-06-01"}→ numeric linkage; regression case{indexCode:110050, ...same}→ must SUCCEED (null coefficients tolerated); add-mm-yyyy-looking date with day>12 → normalized, echoed dates match - get_main_indices
{}and get_main_indices_by_period{startDate:"202401", endDate:"202403"}→ 3 date groups - get_all_indices
{chapter:"a", lang:"en"}For each call assert:isError !== true,content[0].textparses as JSON,structuredContentpresent and consistent with the text.
- get_catalog_chapters
- If ALL tools fail with timeouts/5xx, verify CBS availability before reporting (curl the catalog endpoint) — report "CBS outage" separately from regressions.
Reporting
Output a matrix: tool → case → PASS/FAIL → one-line evidence (key numbers, error text). End with a verdict: SHIP / FIX FIRST (list blockers). Record recurring CBS quirks you discover in your memory directory so future runs anticipate them.
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-tester is an agent published in the GitHub repository reuvenaor/israel-statistics-mcp (4 stars, last pushed 1mo ago), licensed MIT. It adds 54 tokens to every session and 640 once invoked, about $0.0003 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 2026-08-31.
Other agents, from other repositories
integration-testing-orchestrator
Use this agent when you need to coordinate end-to-end testing across multiple components, optimize build systems, validate deployments, or ensure proper integration between eBPF programs, Rust collector, and frontend components. Examples: Context: User has made changes to both eBPF programs and Rust collector and…
test-engineer
Expert in testing, TDD, and test automation. Use for writing tests, improving coverage, debugging test failures. Triggers on test, spec, coverage, jest, pytest, playwright, e2e, unit test.
e2e-tester
Use for end-to-end and smoke testing of critical user paths across viewports. Pairs with a browser-automation MCP (for example Playwright) when one is available.
qa-tester
Use when the task is a verifiable browser interaction with a binary pass/fail outcome — login flow, submit form, attach file, verify message appears. Returns a verdict + evidence. Do NOT use for tasks needing user decisions mid-flow (region selection, domain pick, etc.).
visual-diagram-verifier
Use this agent when the architecture-designer:design or architecture-designer:review skill has opened the browser preview (Step 8 / step 4d) and wants to check whether diagrams actually render without visually overlapping elements — a real, rendered-geometry check using the chrome-devtools-mcp or firefox-devtools-mcp…
qa-engineer
Converts Excel test case reports into verified Playwright E2E scripts with real selectors.
