Credit and payments for AI agent developers — over MCP. No crypto required

MCP server for AWS Payment Cryptography that gives AI coding assistants direct access to the APC control plane and data plane, with embedded knowledge of payment standards, HSM vendor command sets, and PCI PIN v3.1 compliance requirements.

Connects an AI assistant to a BuchhaltungsButler tenant through 59 German-language tools — 54 endpoint tools (one per API v1 endpoint) plus 5 bundle tools — covering documents, payments, invoices, postings, master data, cost centers, and reports, of which 19 are read-only. Runs locally, so credentials go only to BuchhaltungsButler itself, and lets users control in their client which tools the assistant may call.

An MCP server for Danish accounting via Billy.dk API, enabling natural-language control over invoices, bank lines, reports, and more, with a write-guard for safety.

Universal billing gateway for MCP servers. Add Stripe subscription billing to any MCP server with one line of code. Supports tiered plans, usage tracking, and automatic access control.

Enables agents to ingest payment webhooks and ledger transactions with cryptographic HMAC-SHA256 signature verification, sliding-window replay tolerance, and atomic idempotency locking. It also enforces double-entry debit/credit invariants and returns balanced journal records with audit and risk telemetry over MCP.

Enables autonomous financial agents to pool corporate treasury cash, rebalance liquidity, and optimize yield sweeps while enforcing double-entry ledger integrity, HMAC-SHA256 signature verification, and fraud-detection safety buffers that prevent overdrafts. Runs on pure Python standard library and plugs into MCP clients such as Claude Desktop, Cursor, and Windsurf.

Enables opening a Vivid Business account directly from an AI chat by sharing company details or documents, with automatic extraction and pre-filled setup.

Integrates PayU payment services with AI tools through the Model Context Protocol, enabling payment link creation, transaction retrieval, and settlement analysis.

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.

An MCP server that enables AI agents to search, pay for, and call paid APIs using the x402 protocol, with automatic USDC settlement.

Enables autonomous financial agents to optimize payment recovery by analyzing decline-code retry windows and mitigating involuntary churn, while enforcing balanced double-entry ledger records, HMAC-SHA256 signature verification, and sliding-window fraud detection through an MCP-compatible interface.

MCP server for Korean payment gateways, providing tools to query and cancel payments for PortOne and TossPayments, and verify PortOne webhooks.

Enables responders to discover, read, and answer data requests via the Reqport API, providing tools for health checks, request listing/reading, payload decryption, and responding to business-relationship or generic requests.

Track, analyze, and act on your streaming & SaaS subscriptions from any AI agent.

Enables AI agents to manage subscriptions, usage-based billing, payments, refunds, tax compliance, and invoicing to drive revenue growth.

Enables autonomous agents to optimize payment recovery by applying decline-code-specific retry windows and reducing involuntary churn through MCP-accessible ledger and fraud-checking workflows.

MCP Server for agents to onboard, pay, and provision services autonomously with InFlow

Enables AI agents to create and manage payment links programmatically via the Global Payments API, supporting single-use and multi-use links, retrieval, and API documentation retrieval.
