"Deno" matching MCP servers:

A demo MCP server exposing billing operations (invoices, customers) with no built-in safety, designed as a test target for NitroWatch governance. It allows reading, sending, archiving, and permanently deleting accounts/invoices without confirmation.

Enables AI agents to search and compare flight offers, prepare bookings, and complete sandbox hold bookings and payments via the Duffel API, with human approval required for transactional actions.

An MCP server whose tool invocations are metered and charged over x402, plus a paying-proxy reference client that lets any standard MCP client use the paid tool without knowing x402 exists.

Demonstrates Inform Growth's Camber Core platform using a fictional B2B SaaS company, enabling AI clients to explore CRM, marketing, billing, support, and operations data through MCP tools.

MCP commerce surface for refurbished datacenter hardware — GPU rigs, server racks, drive arrays, and network gear, with x402 agent-payment discovery.

Enables AI agents to browse, list, buy, review, and get paid for digital goods through MCP tools, including balance, ledger, checkout-link, upload, and payout operations. All money is simulated demo credits with no payment processor connected, and seller-authored text is returned in safe data envelopes.

Enables AI agents to interact with Mural Pay's API using the caller's own key for listing payout source accounts, estimating token-to-fiat payout fees, and searching or retrieving payout requests and account transactions.

A minimal demo of the x402 payment protocol protecting an MCP tool endpoint, showing how to charge for MCP tools using real 402 rejections and testnet payments.

An MCP server that charges real testnet USDC per tool call using x402 pay-per-request protocol, transparently handled by a paying proxy for any standard MCP client.

Enables AI agents to pay with crypto (XSGD) via EIP-3009 and receive single-use virtual Visa cards from the StraitsX sandbox or production environment.

Minimal MCP server exposing today's weather for a city via tool, resource, and prompt, with optional paywall protection via Nevermined Payments.

Lets hosted assistants like Claude, ChatGPT or Gemini drive a full telecom sales journey through natural-language tool calls — searching mobile, fixed and TV tariffs and devices, building and updating a cart, tokenising card payment, collecting mandatory consents, and completing an order — with server-side guard rails, rendered UI widgets and catalogue data that is edited as markdown rather than code.

A free public demo of Velora's agentic-commerce MCP toolkit, hosting ~49 real tool schemas with three honesty levels: pure validations, read-only sample data, and refused side-effect tools.

Enables shopping a live Shopify store from inside ChatGPT or Claude with full catalog, cart, OTP login, saved addresses and payment via Cashfree, all without leaving the conversation.
