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 | $0.00349 | $0.00349 |
| Opus 5.5 | $0.00140 | $0.00140 |
| Sonnet 5.5 | $0.00070 | $0.00070 |
| Haiku 4.5 | $0.00035 | $0.00035 |
Grade A, and why
kamernet-mcp AGENTS.md 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 2mo 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.

Architecture
src/kamernet_mcp/client.py— httpx +__NEXT_DATA__JSON parsing. ALL Kamernet data access lives here. Never parse HTML with CSS selectors; never call/services/api/*(robots.txt-disallowed).src/kamernet_mcp/models.py— pydantic mapping from Kamernet's raw field names to our stable snake_case API.src/kamernet_mcp/tools/— thin MCP tool layer. Docstrings ARE the tool descriptions agents see; keep them accurate.src/kamernet_mcp/auth.py— Playwright login + reply (experimental, opt-in via env vars).tests/fixtures/*.html— sanitized snapshots of real pages. If Kamernet changes their frontend, refresh fixtures and fixmodels.pymappings.
Hard rules
- The politeness policy is non-negotiable: ≥1s request delay, transparent User-Agent, no disallowed endpoints, reply cap. Do not weaken it, even if asked to "make it faster".
- Tool schemas are public API —
tests/test_schemas.pyguards them; change deliberately. - Never commit secrets or unsanitized fixtures (they contain landlord personal data).
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.
