"Cybersecurity penetration testing frameworks" matching MCP servers:

A Model Context Protocol (MCP) server that provides testing and debugging tools for Stripe integrations, including test clock management, customer and product management, and subscription testing.

Enables AI assistants to parse, validate, send, and inspect X12 EDI documents via the SignalEDI Core API, with optional QuickBooks integration and a demo mode for keyless local testing.

Enables interaction with the Centrapay payments API for testing NZ payment flows, including creating, managing, and settling payment requests through natural language.

Enables AI coding agents to integrate MONA Pay payments directly from the IDE, including creating VietQR codes, checking transactions, configuring and testing webhooks, verifying HMAC signatures, and generating webhook sample code.

Enables interaction with Safaricom M-Pesa Daraja 3.0 API, covering payments, disbursements, treasury, and fraud checks, with a built-in simulator for testing without credentials.

Single-tenant MCP server for Polish KSeF e-invoice workflows, supporting local stdio testing, draft management, and invoice submission with safety gates.

Enables autonomous financial agents and payment systems to analyze transaction streams in real time, detect velocity-based fraud patterns such as card testing, volume spikes, and account takeovers, and produce balanced ledger records with audit telemetry.

A one-command paywall for local servers that enables testing AI agents' payment flows by simulating HTTP 402 Payment Required responses. It proxies requests with valid payment headers to the actual server, making it easy to develop and test x402 client logic without real blockchain transactions.

MCP server enabling natural language interaction with the Bolt API for managing transactions, orders, product catalog, configuration, and testing.

Enables autonomous financial agents to submit payment webhooks, ledger entries, or transaction streams and receive balanced journal records, risk verification dossiers, and detection of card-testing clusters, volume spikes, and account takeovers.
