A verification workflow for an MCP server, a program that exposes defined tools to an AI client. It runs code checks, tests, a build, an offline protocol check, and selected live checks when relevant.

Use it after changing the server’s source code to check the nine-tool interface, invalid-argument errors, standard output, build output, unit tests, and selected live data requests.

It catches compilation, linting, test, startup, protocol, output-format, and calculator regressions before changes are committed. It stops at the first failure and distinguishes broad service outages from individual tool failures.

Token cost

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	$0.00041	$0.00447
Opus 5	$0.00020	$0.00224
Sonnet 5	$0.00008	$0.00089
Haiku 4.5	$0.00004	$0.00045

Security

Grade A, and why

verify 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 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.

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.

What it actually says

Verify the MCP server

Run these in order; stop and report at the first failure.

Static gates: pnpm typecheck && pnpm lint
Unit tests (offline): pnpm test — must pass with no network.
Build: pnpm build — confirm dist/index.js exists and starts with #!/usr/bin/env node.
Offline smoke: node scripts/smoke.mjs
- Asserts: Inspector CLI connects (a connect failure usually means a capabilities regression — see CLAUDE.md), tools/list returns exactly 9 tools, an invalid-args tools/call returns a clean error (no raw ZodError dump), stdout stayed protocol-clean.
Live spot-check (only if the change touches fetcher/schemas/handlers and network is OK): node scripts/smoke.mjs --live — includes the 110050 null-coefficient regression (must succeed) and 120010 happy path.
Report a pass/fail matrix per step. For live failures, distinguish CBS-side outage (5xx/timeouts across ALL tools) from a real regression (single tool/schema failure) before blaming the change.

The built server is also wired in .mcp.json as israel-statistics — for a final human-level check, call one tool through the MCP connection (e.g. get_catalog_chapters {lang:"en"}) and confirm both content text and structuredContent are present.

Changes

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.

verify is a skill published in the GitHub repository reuvenaor/israel-statistics-mcp (4 stars, last pushed 1mo ago), licensed MIT. It adds 41 tokens to every session and 447 once invoked, about $0.0002 per session on Opus 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 2026-08-31.
