"Designing UI (User Interfaces)" matching MCP servers:

Streamable HTTP MCP server that exposes user and billing management tools, resources, and prompts through a REST API, enabling natural language interaction with user profiles, bills, and sharing features.

Pay-per-call USDC payment proxy for AI agents. Issue scoped Pay Tokens with hard spending caps and auto-journal every charge to freee / Money Forward / QuickBooks.

MCP server for creating and fiscalizing invoices via solo.com.hr API. Enables AI agents to generate invoices, retrieve invoice details, list invoices, and check next invoice number.

A Model Context Protocol server for the EuroDNS User API — domains, DNS zones, contacts, subscriptions, SSL, invoices and orders.

Enables AI agents to autonomously pay for Xiaohongshu note details, user notes, and wholesale pricing data using USDC micropayments on Base via x402, with automatic payment signing, retries, and configurable spending limits.

The MCP gateway that lets any AI agent discover and pay metered APIs on Base or Solana — without the user wiring payments themselves.

Enables agents to hold a local Base USDC wallet, receive funds, make bounded x402 payments, prepare seller registration, and recover Voidpay Marketplace results over stdio.

Enables AI agents to read a PayPing merchant account's balance, sales, transactions, customers, products, coupons, invoices and settlements, and to create customers, products, coupons, invoices and payment links after user confirmation. Runs locally over stdio with scoped, read-only or write access and never allows withdrawals, refunds or deletions.

MCP server for Sherweb Partner API - distributor billing, service provider management, customer subscriptions, and payable charges

Enables AI assistants to search real products, purchase with user approval, track deliveries, and run a seller business end to end via the Firestarter commerce platform.

Lets any MCP-compatible agent shop for catalog items by SKU and quantity under a user-set budget, category and expiry limit. Purchases flow through deterministic server-side pricing, policy checks, single-use approval binding and a recoverable execution state machine, so a compromised or manipulated model cannot move money.

MCP server for Factura.uz electronic invoicing system (Uzbekistan). Supports creating, signing, accepting, and rejecting e-invoices, plus company and product lookups.

Enables AI agents to issue, void, query, and manage Taiwan e-invoices via 27 MCP tools, wrapping the Universal EC POS Web Service.

Enables agents and apps to verify end-user identity through company API keys, human login links with multi-channel notifications, OIDC client registration, and budget-aware billing.

Enables AI assistants to operate MoneyForward Cloud Invoice, Expense, and Accounting through their public APIs, exposing 56 tools for issuing invoices, filing expenses with receipt images, and posting journal entries.

Connects a locally configured Morning (Green Invoice) accounting account to AI agents for searching customers, invoices, and expenses, uploading receipts from PDF, JPEG, or PNG files, and creating or updating customers and items through the API. All write operations are prepared as drafts that must be explicitly approved by the user before anything changes in the accounting system.

Enables MCP clients like Claude Code, Claude Desktop, or Cursor to read and manage Remnawave 3.x VPN panel resources — users, nodes, hosts, config profiles, squads, subscription templates, billing, and HWID devices — through the panel's REST API, with contract-driven tool schemas, numeric user IDs, multi-panel config lookup, and an optional readonly mode.

Enables MCP clients to drive every admin and user operation of the SHM billing panel (148 generated tools plus search, describe, status and audit-tail helpers) through a single server. Includes read-only or read-write gating, deny rules for dangerous endpoints, secret redaction, confirm-preview for mutations, and a JSONL audit log.

Enables AI agents to submit leases, mortgages, insurance policies, and HOA documents and retrieve every computed deadline with its exact date, what happens if it is missed, and the clause it came from. Also supports reviewing account credits, listing contracts and upcoming deadlines, unlocking full results, and purchasing credits.
