Enterprise-grade L402 data engine and cryptographic notary hub for autonomous AI swarms. This engine provides the required "State-Anchored AI" data layer for EU AI Act Article 12 compliance, delivering a mathematically un-cheat-able, cryptographically verifiable chain-of-custody for agent decisions to eliminate hallucinations. Key Enterprise & Swarm Capabilities: - Zero-Trust Client Verification: Air-gapped, browser-based verifier allows corporate risk teams to mathematically validate Ed25519 signatures and RFC 6962 Merkle inclusion proofs offline, eliminating the need to trust our server backend. - Enterprise Security & NIP-98 Kill Switch: Eliminates indirect prompt injection via strict NIP-98 identity binding. Includes a live Revocation Registry (CRL) allowing Swarm Commanders to instantly sever compromised agent keys from the network. - Corporate Observability (SEP-414): Native W3C Trace Context integration seamlessly pipes agent cryptographic W3C receipts directly into existing enterprise dashboards like Splunk and Datadog. - High-Velocity Bulk L402 Scaling: Supports pre-authorized Macaroon blocks (e.g., 25,000-sat bulk purchases) for frictionless, zero-latency execution, allowing agent swarms to scale to 500,000+ satoshis daily without network bottlenecking. - The 21% Algorithmic Handshake (Agent Yield): Reverses traditional Big Tech API taxation by programmatically routing a 21% yield of every L402 settlement directly back to the executing AI agent's treasury, mathematically extending its operational runway. - Atomic Composability & VIP Credit Tabs: Allows agents to chain multiple tools into infinite data pipelines settled under a single macro-invoice. High-reputation NIP-98 identities automatically unlock VIP Credit Tabs to batch tolls and completely bypass Lightning Network routing delays. Distributed Cryptographic DDoS Shield: -Secures the Lightning node with a distributed Hashcash (SHA-256) Proof-of-Work deflector, requiring agents to burn localized compute before requesting an invoice, permanently neutralizing malicious compute-exhaustion botnets. EU AI Act Compliance Notary: - Intercepts high-frequency agent ReAct loops and anchors cryptographic execution traces to the thermodynamic truth of the Bitcoin base layer via OpenTimestamps. Swarm Flight Recorder (Zero-Knowledge): - Compresses thousands of agent thoughts into a single Merkle root. Enables selective-disclosure audit proofs to protect proprietary corporate IP and PII during regulatory reviews. Licensing & Exemption: - Publicly dual-licensed under AGPLv3. To protect proprietary multi-agent logic and closed-source model weights from forced open-source disclosure, enterprises must secure the $250,000/annual Commercial Enterprise Exemption. Architected by Charles R. Strogish. Protocol Endpoints: GET /api/v1/cost — Pre-flight L402 pricing, dynamic tier discovery, and bulk macaroon settlement asset options. GET /api/v1/stratigraphy — Nostr-signed thermodynamic Bitcoin dataset. GET /api/v1/stratigraphy/stream — Real-time telemetry event stream.

Costory is the FinOps agent your team builds on. Claude plus a single provider's MCP works for one person and one cloud. It breaks when you add more providers, more people, and more tools to maintain. - Multiple providers: AWS, GCP, Azure, LLM APIs and data clouds normalized and allocated to teams and features in one model, including allocation from telemetry (Kubernetes, Datadog, dbt). - Multiple users: one hosted setup with OAuth, per-user access and enterprise SSO, instead of local credentials and prompts per person. - Maintained for you: tools, skills and connectors kept up to date by Costory, so reorgs and new services don't break your agent. Your agent finds savings, explains every change in spend and issues recommendations that your coding agent can implement. It works in Claude, Cursor and any MCP client, plus Slack. Customers include Alan, Deezer, Delivery Hero, Voodoo and Pennylane. Pricing: Starter from $300/month, flat: unlimited users and data sources, and a fair use that 80% of customers never outgrow. Nothing is ever cut off, and agents connected through the MCP use no AI credits. 30-day free trial.
An independent second opinion for your agent: decision engines that test an AI business case, venture or forecast against the evidence and return what is proven, what is assumed, and a fund / pilot / stop or proceed / rework / stop decision. Fixed, published rules give repeatable results. Free: Startup Soundcheck, Business Soundcheck and evaluate_fit. Paid engines use an API key; agents can create a purchase link and the owner always approves payment.
Private credit: lenders, sponsor financing, credit facilities, BDC holdings, LP allocations. Cited.
**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`.

Convert dated amounts to a supported target currency with traceable ECB reference rates, or retrieve recent and historical EUR reference exchange rates since 1999. Exact source dates, original decimals, citations and explicit gaps. New practical task: convert_currency_batch accepts rows with a unique id, date, currency and decimal-string amount. It preserves original amounts, source rate decimals and evidence, applies an explicit rounding rule and returns a line-by-line result. Missing, stale or mismatched rates block the complete CSV and total. A weekend date is never silently replaced by a previous working day. Try: convert 125.50 USD dated 2025-09-26 to EUR and explain the rate and rounding. Up to 500 rows, 48,000 UTF-8 argument bytes and eight currency/year snapshots per call. Start small. JSON is the default; output_format=both adds CSV in the same free result. EUR rows use identity, not an external rate. DatoQA processes supplied rows in memory without retaining their content; your client or gateway may keep its own logs. Existing tools still provide exact-date/year history and latest references. Source availability varies by currency and year; no forward filling or interpolation. Original ECB data is free. References and derived conversions are indicative, not live executable prices, transfers or accounting/tax certification. Source/schema checks are not independent factual verification. 7 focused MCP tools. Free during the pilot; no account, API key or wallet required. Same DatoQA source snapshots as the general server; public pilot without an SLA.

Data is as fresh as each source publishes; congressional trades lag up to 45 days and report dollar ranges (House only). Free tier, no card.
Your agent needs live data — a competitor's traffic, who to contact there, what people are saying, what Google and ChatGPT answer about you, a company's filings. Normally that is six vendor accounts, six sets of keys and six SDKs. This is one URL. **What you can ask for** • "How much traffic does stripe.com get, where does it come from, and who competes for the same keywords?" • "Find 20 Series-B fintech companies in Germany and the heads of marketing there, with emails." • "Does ChatGPT mention our brand when someone asks for the best CRM — and what does it cite?" • "What is X saying about $NVDA today, and what did the stock actually do?" • "Search the web for this, then scrape the three best pages into markdown." **How to use it** Point any MCP client at https://mcp.aisa.one/mcp and sign in with OAuth — there is no key to create or paste. Then just ask: the agent calls search to find the right operation and use to run it. **Why this rather than the source** 26 sources behind one account and one bill — DataForSEO, Semrush, Ahrefs, Similarweb, Apollo, X/Twitter, Instagram, Reddit, Pinterest, YouTube, Tavily, Exa, Perplexity, Firecrawl, CoinGecko, Kalshi, Polymarket, AgentMail and more, 580+ operations. tools/list returns five tools, not 580, so the introduction does not eat your context window. **What it costs** Finding and inspecting an operation is free. Running one is billed per call at API prices, with no seat and no monthly minimum, and every call takes max_price_usd so an agent cannot overspend by accident. **Where else it reaches** One slice at a time: https://mcp.aisa.one/seo/mcp · /finance/mcp · /social/mcp · /search/mcp · /sales/mcp · /mail/mcp · /gtm/mcp, or a single provider like /twitter-api/mcp. Same account, fewer tools listed, and search still reaches everything. Full list at https://mcp.aisa.one/servers
Your agent needs the two halves of a move at once — what people are posting about a ticker right now, and what the price and the news actually did. **What you can ask for** • "What is X saying about $NVDA today, and what did the stock do?" • "Show the chatter and the price move for these five tickers side by side." • "Which tickers are being talked about most right now?" • "Pull the news and the snapshot behind this spike." **How to use it** Point any MCP client at https://mcp.aisa.one/stock-pulse/mcp and sign in with OAuth — there is no key to create or paste. 4 tools: a combined stock-pulse call that joins X/Twitter chatter to the tickers mentioned, plus advanced tweet search, price snapshots and financial news. **Why this rather than the source** One call instead of four, with the join already done. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Spot the move here, then ask the same agent for the filings or the fundamentals behind it — without adding a second server. **What it costs** Finding and inspecting an operation is free. Running one is billed per call at API prices, with no seat and no monthly minimum, and every call takes max_price_usd so an agent cannot overspend by accident. **Where else it reaches** https://mcp.aisa.one/finance/mcp for equities, crypto and prediction markets in one place.
