AiSeek is a global change-intelligence platform that connects AI assistants and autonomous agents to structured, source-linked information about developments across the world. Rather than providing a conventional news feed, AiSeek focuses on identifying meaningful changes, preserving their context, and making the underlying sources accessible. What a source says (fact) is kept apart from what it may mean (hypothesis). Coverage spans artificial intelligence, technology, global economics, financial markets, companies, government policy, science, and other major domains. The MCP server provides sixteen read-only tools. Every name follows one pattern: list_, get_, search_ or verify_. Changes and context: • list_changes — Browse the newest published changes, newest first, 20 per page. • search_changes — Search changes by words in English, Chinese or Japanese, ranked by relevance. • get_change — One change with its sources: outlet, link, date, evidence level and role. • list_topics — Browse curated topics, optionally by coverage domain. • get_topic — One topic and up to 50 of its recent changes. • get_latest_brief — The latest daily or weekly brief. • list_scheduled_events — Upcoming central-bank decisions, data releases, earnings, rule dates and more. Companies: • search_companies — Find a company by name, alias or ticker. • get_company — A company's profile, listings, recent changes, stated facts and relations. Countries and SeekEarth: • list_countries — Every country with its name and this week's number of changes. • get_country_heat — Change Heat per country against its own normal, with a seven-day series. • get_earth_view — One place and moment on SeekEarth: changes, heat and the Earth's layers. Evidence (SeekTrace): • get_change_history — A change's evidence receipts and what AiSeek knew at an earlier time. • get_receipt — One evidence receipt. • verify_receipt — Check that a stored receipt is unchanged. • list_corrections — Public corrections, newest first. Tool calls need an AiSeek API key (Authorization: Bearer or the x-api-key header), made at aiseek.dev/en/account; the handshake and the tool list are open. Optional connection defaults go on the endpoint URL: ?locale=en|zh|ja&limit=1-50&domain=MARKETS. Answers carry sources and links, never quoted passages.

**UNE Maritime Decarbonization & Compliance Gateway** is a production-grade, deterministic Model Context Protocol (MCP) server engineered for maritime shipping operators, charterers, compliance auditors, and AI agents managing EU environmental regulations. Strictly modeled on **Regulation (EU) 2023/1805 (FuelEU Maritime, Annexes I–IV)** and **Directive (EU) 2023/959 (EU ETS Maritime)**, the gateway guarantees audit-grade calculations with inter-process SHA-256 cryptographic state proofs. ### Core Capabilities & Statutory Tools (7) * **`lookup_fuel_wtw_emission_factor`**: Statutory Well-to-Wake (WtW), WtT, TtW, and LCV factors under FuelEU Maritime Annex II default tables (VLSFO, LNG, Biofuels, e-Methanol, e-Ammonia). * **`calculate_voyage_ghg_intensity`**: Multi-leg voyage GHG intensity solver adhering to FuelEU Annex I, enforcing Article 2 scope coverage (100% intra-EU, 50% extra-EU voyages) and UN/LOCODE port consistency. * **`calculate_fueleu_banking_borrowing`**: Article 20 deficit borrowing and surplus banking engine, verifying statutory 2% caps, consecutive-year constraints, and statutory 1.1× carbon penalty interest. * **`optimize_fueleu_pool_allocation`**: Article 21 compliance pooling optimizer solving fleet allocations to eliminate non-compliance penalties on China–Europe and global trade lanes. * **`calculate_fueleu_maritime_penalty`**: Statutory cash penalty calculation based on the Annex IV formula ($€2,400$/t VLSFO-eq reference rate with multi-year non-compliance escalators). * **`calculate_maritime_ets_surrender`**: EU ETS allowance (EUA) liability calculation implementing phased-in surrender obligations (40% in 2024, 70% in 2025, 100% in 2026+) and dynamic $N+1$ regulatory surrender deadlines (Sept 30). * **`provision_free_api_key`**: Developer provisioning engine delivering sandbox API keys for verifier XML manifests and BIMCO clause liability auditing. ### Key Highlights * **Cryptographic Determinism**: Every computation yields an immutable `result_hash` that remains constant across process restarts and environment redeployments. * **Ultra-low Latency**: Sub-millisecond execution times with zero external API dependencies for raw regulatory computations. * **Streamable HTTP Endpoint**: Publicly accessible via standard JSON-RPC 2.0 at `https://maritime.une.education/mcp.php`.
