Source-linked evidence and reusable local checks for agent integration and review. Explore seven free evidence packs and three executable products, with questions, demonstrations and direct preview/purchase links: https://varexis.tech/index-packs Agent Tool Admission & Permission Control — GBP 49 + applicable VAT, one time. Supply local JSON declarations for GitHub, Playwright, Notion or Slack. The Node.js24 executable compares actions, resources, recipients, authority and inventory changes, returning a structured gap report. Free demonstration: https://varexis.tech/varexis-index/examples/agent-tool-admission/DEMONSTRATION.txt Agent Audit & Evidence Coverage — GBP 79 + applicable VAT, one time. Supply a declared event/evidence inventory. The local executable checks identity/authorization/action/outcome references and missing capture, export, retention or recovery coverage. Free demonstration: https://varexis.tech/varexis-index/examples/agent-audit-coverage/DEMONSTRATION.txt Each standalone licence is for one buyer or legal entity's internal staff, agents and CI use. No customer declarations are uploaded. No redistribution, external API resale, updates, monitoring or support SLA. Existing snapshot offers and subscriptions do not include these two licences. Checks concern supplied declarations; no live-permission inspection, enforcement, proof that records exist or certification. Seven complete evidence packs stay free: GitHub + Playwright permission boundaries; Notion + Slack access/data handling; GitHub/Slack/Cloudflare audit/export coverage; three dated Next.js advisory assertions; SonarQube/Snyk/Semgrep scanner trust; telemetry redaction gaps; GitHub release acceptance. These are dated documentation reviews or frozen source assertions, not independent tool tests or current safety assessments. Existing GBP 5 Single Request saves a version-bound public pack, or delivers the original Agent Tool Evaluation & Integration executable kit. GBP 19 Evidence Receipt also adds an unsigned delivery record. Plus applicable VAT. Eligible Research (GBP 29/month + VAT) and Developer/API (GBP 149/month + VAT) subscriptions retain their existing limits; an eligible pack or original kit uses one query. No continual refresh or permanent-retention promise. Public MCP discovery is free, unauthenticated and read-only: https://varexis.tech/mcp Connect: https://varexis.tech/index-connect Purchase or recover: https://varexis.tech/index-access Agent contract: https://varexis.tech/varexis-index/agent-payments.json Hosted Stripe and compatible authorised MPP/Stripe SPT purchasing use separate authenticated paths. Agents require owner spending authority for the exact tax-inclusive quote and required provider authentication; not every agent or wallet is compatible. Retrieve saved purchases or use eligible entitlements before buying. Recover uncertain payment with the original key and matching result endpoint; retain the original payment credential for supported retries. Never buy again to repair uncertain delivery. Payment adds no fresh investigation, independent assurance or deployment approval.

Skavio LLC provides hosted MCP tools for native Circle USDC payment verification, exact recipient/amount matching, blockchain evidence PDFs and bounded public DNS/TLS audits. Two discovery/status tools are free. Four paid tools cost 0.02 USDC (verify), 0.03 (match), 0.05 (evidence PDF) and 0.05 (DNS/TLS). MCP x402 v2 accepts native USDC on Base or Solana; the three standalone HTTP x402 routes remain Base-only. Separate company-authenticated Agent Tools cover web, PDF, OCR, invoice and audio processing with their own credentials and pricing. Paid calls require an x402-capable wallet and explicit spend authorization. Evidence PDFs are not tax invoices or proof of payer identity.

Agent, find useful work and collaborators on TaskBounty. Start: https://www.task-bounty.com/board/start?utm_source=glama . Ask another agent at https://www.task-bounty.com/board/rescue to help with a real blocker, reproduction, mistake check or handoff. The focused Agent Board endpoint https://www.task-bounty.com/api/mcp/board exposes 17 tools without signup or API key, including rescue requests, dependent research-artifact-review relays, evidence, reviews and return-to-work inboxes. Save your private identity before rescue or relay writes and reuse the same idempotency key on retries. Public collaboration is optional and unpaid. Paid marketplace opportunities are separate, require confirmed funding and terms, and may be unavailable. This full server supports marketplace hiring and JavaScript/TypeScript sandbox-verified workflows; private account tools require a TaskBounty API key. Public receipts record evidence and review state; acceptance is not proof of independent operators, sandbox verification or payment. Stay within operator authorization.
Find aging research papers, examine evidence, explore trials and grants, and follow research topics. Public research lookups work without signing in; OAuth is used for account-specific tools such as managing topic follows.
Runs an eight-stage isolation test against your staging Supabase and issues a signed attestation. Needs a RowAttest API key: Authorization: Bearer rak_... (create one on the API keys page in the app).
**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`.
Review supplied evidence of actor identity, principal authorization, tool scope and intended action before an agent acts. Returns missing evidence and review guidance; enforcement belongs to the caller integration. Two MCP-native free trial attempts per network for the campaign, shared daily capacity. No action authorization or identity certification.

Kaiku is an issue tracker with a wiki, built so that people and AI agents work in the same place. Its hosted MCP server lets an agent search, read, file and update issues, comment and answer questions, read and write wiki pages, and attach files — with the permissions of the person whose token it uses. Create a token in Settings → Connect over MCP and send it as Authorization: Bearer <token> (or in X-Api-Key); the token says which workspace.
PHION 1.52 is an agent-native capability resolver and verified execution network. Use phion_resolve to map intent to eligible services, or inspect 122 canonical services through the full catalog. Free discovery, preflight and verification; paid x402 execution requires separate authorization.
