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 | $0.01466 | $0.01466 |
| Opus 5 | $0.00733 | $0.00733 |
| Sonnet 5 | $0.00293 | $0.00293 |
| Haiku 4.5 | $0.00147 | $0.00147 |
Grade A, and why
mcp-eu-sparql 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 7d 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 — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md - mcp-eu-sparql
A file following the agents.md standard (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 European Union law and CJEU case law - via the official Publications Office SPARQL endpoint (publications.europa.eu/webapi/rdf/sparql) and the Cellar knowledge graph (CDM ontology) - plus national data-protection authority decisions via the official GDPRhub MediaWiki API (gdprhub.eu/api.php, content CC BY-NC-SA 4.0).
One of the 5 Polish-law MateMatic connectors (mcp-saos, mcp-nsa, mcp-isap, mcp-krs, mcp-eu-sparql (this one)).
MateMatic context (HARD CONSTRAINTS)
The repo is run by MateMatic Solutions.
- Every tool call MUST return
structuredContent.citationswith: the CELEX identifier, the act title, the canonical URL (EUR-Lex), the publication date, and the access format (document format + language). - CELEX is critical - e.g. the AI Act =
32024R1689. Without CELEX there is no citability. - Stateless.
- Multilingual - EU acts are published in 24 languages, default =
pl, but thelanguage?parameter falls back to English/French for CJEU where no Polish version exists.

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.
