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 | $0.00067 | $0.00704 |
| Opus 5 | $0.00034 | $0.00352 |
| Sonnet 5 | $0.00013 | $0.00141 |
| Haiku 4.5 | $0.00007 | $0.00070 |
Grade A, and why
verify-auth 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 9d 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.

The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Verify appium-mcp-auth
Run the complete quality gate and report pass/fail crisply. Stop and report at the first failing stage; do not "fix" by editing appium-mcp core (forbidden — see CLAUDE.md).
Stages (run in order)
-
Typecheck (source only):
npm run typecheck -
Unit tests (60 tests via node:test + tsx):
npm testExpect
pass 60 / fail 0. If a test fails, show the failing assertion. -
Build (emit dist/):
npm run build -
SSE smoke boot — start the real server with a throwaway key, confirm the plugin registers and the health endpoint answers, then stop it:
export APPIUM_MCP_AUTH_API_KEYS='[{"id":"smoke","secret":"smoke-secret","subject":"smoke","scopes":["appium:use"]}]' export APPIUM_MCP_AUTH_AUDIT=false PORT=8791 node dist/cli.js --httpStream --port=$PORT --endpoint=/sse > /tmp/amauth-verify.log 2>&1 & SVPID=$! for i in $(seq 1 40); do grep -q "listening on" /tmp/amauth-verify.log 2>/dev/null && break kill -0 $SVPID 2>/dev/null || { echo "SERVER EXITED EARLY"; break; } sleep 0.5 done cat /tmp/amauth-verify.log curl -s -o /dev/null -w "health HTTP %{http_code}\n" http://localhost:$PORT/health kill $SVPID 2>/dev/null; wait $SVPID 2>/dev/null; rm -f /tmp/amauth-verify.log
Pass criteria
- typecheck: exit 0, no output

Notes
- Requires
appium-mcpinstalled (it is a regular npm dependency) since the plugin composes into it at runtime. - The smoke boot needs no real device — it only starts the transport and registers tools; it does not create an Appium session.
- If the port is busy, pick another (e.g. 8792) and reuse it consistently.
- Report a one-line summary at the end: which stages passed and any failure.
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-auth is a skill published in the GitHub repository appclawhq/appium-mcp-auth (5 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 67 tokens to every session and 704 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.
