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 | $0.01021 | $0.01021 |
| Opus 5.5 | $0.00408 | $0.00408 |
| Sonnet 5.5 | $0.00204 | $0.00204 |
| Haiku 4.5 | $0.00102 | $0.00102 |
Grade A, and why
mcp-nsa 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 13d 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.
How it starts
The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md - mcp-nsa
An agents.md standard file (Linux Foundation / Agentic AI Foundation) - canonical instructions for AI agents working with this repository. Read natively by Cursor, Codex (OpenAI), Jules (Google), Devin / Windsurf, Aider, Amp, Factory, GitHub Copilot.
Project goal
An MCP (Model Context Protocol) server for the case law of the Polish administrative courts - Naczelny Sad Administracyjny / NSA (Supreme Administrative Court) + 16 Wojewodzkie Sady Administracyjne / WSA (regional administrative courts) - via the CBOSA database (orzeczenia.nsa.gov.pl).
This is where Polish GDPR / tax / administrative case law lives - practically every ruling of interest to compliance and tax law firms.
One of MateMatic's 5 Polish-law connectors (mcp-saos, mcp-nsa (this one), mcp-isap, mcp-krs, mcp-eu-sparql).
MateMatic context (HARD CONSTRAINTS)
The repo is run by MateMatic Solutions. The connector is trust infrastructure.
- Every tool call MUST return
structuredContent.citationswith: ruling title, canonical URL (CBOSA), court (NSA / WSA + location), date, case number. - Stateless - no caching of queries with PII.
- No text modification - a faithful copy from CBOSA.
- Rate limiting on the connector side - CBOSA has no official API; we scrape carefully, with respect for the court's resources.

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.
