Category kits
The whole outbound motion or the whole teaching practice in one bundle — 12 multi-bundle kits for teams that want a category covered, not a single tool.
One license key. Every premium tool on every Moltline MCP server.
- Unlocks premium tools across all 22 Moltline MCP servers — current and future
- Security deep-dives, governance policies, full personas, premium skill packs
- Key shown on screen the moment payment confirms, and emailed too; auto-renews with your subscription
- Works anywhere MCP does: Claude, Cursor, Codex CLI, Gemini CLI…
- Cancel anytime — your key simply expires at period end
Pay in ETH, USDT, SOL and 300+ coins via NOWPayments. Your license key appears on screen as soon as the payment confirms, and is emailed to you as well. Marketplace bundles on Agensi are one-time purchases sold separately.
$19 is the individual price. It is deliberately in the same band as the other tools on a developer's card — but a company cannot put a personal subscription through procurement, and an agent that wants one analysis should not have to buy a month. So there are three other ways in.
Team — $99/month
Five seats on one invoice, so it goes through expenses instead of someone's personal card. Same-day support with a named contact rather than a shared inbox, and a single renewal date your finance team will not query.
Company — $399/month
Unlimited seats across the organization, a written response-time commitment, and the option of a private deployment on your own infrastructure if your security review needs the servers inside your perimeter. Purchase order and invoice billing.
Per call — for agents
No subscription, no account, no human. An autonomous agent pays for the single premium
call it wants, settled in USDC on Base through the
x402 challenge at /api already live on this domain.
This is the one nobody else offers yet, and the discovery crawlers are already asking for
it — we see them in our logs daily.
FAQ
How does the license work?
You get a signed MOLT- key on screen the moment your payment confirms, and by email as well. Paste it into any Moltline server’s credential field (MCPize asks once). Servers validate it offline — no account, no cookies, no cross-site tracking.
What stays free?
Every server’s free tier — 110 free tools across 22 servers — plus a free gateway skill for all 138 bundles, on GitHub and through the catalog server. Free is forever; premium adds depth, not hostages.
Is this a subscription for the Agensi bundles too?
No — Agensi bundles are one-time purchases on Agensi. All-Access covers the premium tools on Moltline’s MCP servers.
