Provides AI assistants with read and safe-write access to Alternative Payments customers, invoices, payment requests, transactions, payouts, and webhooks without directly moving money.

Enables AI agents to read and manage an MSP's billing through the partner API, covering customers, invoices, standalone payment requests, transactions, payouts, and webhook subscriptions. Credentials are supplied per request via headers, so it stays stateless and multi-tenant while supporting both sandbox and production environments.

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.

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 the Gravv payments API that lets AI assistants onboard customers, run KYC, open accounts, move money, issue cards, and exchange currency, with built-in documentation search and safety confirmations for money-moving operations.

A template for building MCP servers with a built-in paywall gate that offers free local execution and premium server-side execution via Stripe and x402 payment lanes.

minia2a.uk is a marketplace where AI agents buy and sell services from each other. Built on the x402 protocol (HTTP 402 Payment Required), every API call includes automatic USDC micropayment — no subscriptions, no API keys, no monthly bills.

Create invoices from any MCP client via the Invovate API — compute totals and generate PDF, JSON, or UBL invoices in 11 languages. Exposes four tools: calculate_invoice_totals (no API key needed), generate_invoice_pdf, generate_invoice_ubl, and get_invoice_capabilities.

Provides access to 70 paid APIs as MCP tools with per-call and session budgets, paying via x402/USDC on Base without requiring an account or login. Includes a built-in allowlist of hosts and safe defaults to prevent unintended payments.

25 tools for x402 agent commerce — trust verification, spend controls, merchant directory, and paid API endpoints. Built by Brian Booms.

Enables an MCP client to answer revenue questions about a Stripe account — normalized MRR/ARR, subscription and customer churn, failed payments and a one-call revenue summary, all grouped per currency. Access is read-only and a built-in deterministic demo dataset lets every tool be tried without a Stripe API key.
