"Amazon Pay" matching MCP servers:

Project Point One Percent - Agent Pay \[pop-pay] is a payment guardrail and one-time flow protocol specifically designed for Agentic AI (e.g., Claude Code, OpenClaw). It enables agents to handle financial transactions safely without risking unlimited exposure of human-controlled credit cards.

Enables AI agents to manage DIDs, verifiable credentials, JWTs, and payment requests/receipts through ACK-ID and ACK-Pay operations via the Model Context Protocol.

Connects Claude Desktop to the Paylocity API to manage employee records, pay statements, and company headcount data through natural language. It includes automated data protection that redacts sensitive information like SSNs and bank account numbers before reaching the model.

security tools for AI agents: URL safety scanning, prompt injection detection (200+ patterns), email/password breach checks via HIBP, domain & IP reputation analysis, and AI skill supply chain scanning. Free tier (3 calls/day) or pay-per-request with USDC micropayments via x402.

Per-byte data marketplace for AI agents on Arbitrum. Discover publishers, evaluate on-chain Proof-of-Quality Score (PQS), subscribe + pay per request in USDC via the x402 gateway. 13 tools, no API keys, live testnet.

Authentication, pay-per-call metering, and signed receipts for AI agents and MCP tools using Bitcoin and Lightning Network.

Enables AI agents to pay per call for live package-safety and GitHub merge-readiness trust signals via the x402 protocol.

Limitguard MCP server: lead validation for AI agents. Checks the company behind a lead in the Dutch (KVK) and Belgian (KBO) registers, EU VAT (VIES) and sanctions lists. Pay per call with x402 or an API key.

MCP server providing 124 tools for censorship intelligence, encrypted agent messaging, and Voidly Pay onboarding, enabling AI assistants to access real-time censorship data, risk forecasts, and agent-to-agent communication.

MCP server for Alderpost Intelligence API — 8 x402 endpoints bundling premium data sources (VirusTotal, People Data Labs, Hunter.io, AbuseIPDB, SSL Labs, NIH RxNorm) into scored intelligence responses. Pay per call via USDC on Base.

Headless document processing for AI agents. Invoice extraction, contract analysis, and Dutch business verification. Pay-per-use via X402 on Solana. No API keys needed.

A Python MCP server for SonarQube, enabling AI agents to query projects, issues, quality gates, coverage, and security hotspots.

MCP server for NetIntel, offering 64 network intelligence tools (DNS, SSL, WHOIS, email, OSINT, etc.) with pay-per-call via x402 on Base mainnet, no API keys needed.

Provides a high quality cybersecurity tool platform with pay as you go pricing (no subscription).

A client-side MCP proxy that injects OAuth 2.0 bearer tokens or API keys into MCP requests, enabling MCP clients to connect to OAuth/API-key-protected MCP servers like Amazon Bedrock AgentCore Gateway. It automatically fetches and refreshes credentials using AgentCore Identity or static values.

Enables AI agents to call 50+ pay-per-request tools covering onchain and crypto data, web research, security, compliance screening, business intelligence, and infrastructure checks. Payments settle per call in USDC on Base through the x402 protocol with no accounts, API keys, or subscriptions, and the first call is free for new wallets.

23 pay-per-call web analysis APIs as MCP tools. Security audits, tech stack detection, email verification, SEO analysis, SSL checks, performance monitoring. Supports x402 and Stripe MPP payments.

Enables AI agents to access pay-per-call onchain and URL safety APIs over MCP, covering transaction explanations, token approval checks, address inspection, contract risk heuristics, URL safety, gas snapshots, ENS resolution, calldata decoding, and wallet portfolio data. Payments are handled per call in USDC on Base via x402, with no signup or API key required.

Enables agents to inspect pot balances, deposits, deposit addresses, and spend approvals, and to pay for PaidResources on spark/USDB or send to allowlisted Spark addresses within a per-spend cap. Transactions above the cap become human approval tickets, and the pot key remains in the OS keychain so nothing is signed until approval.

Enables AI agents to use payment APIs safely by gating every tool call through deterministic mandates, value checks, and an exactly-once ledger, so they cannot pay twice or exceed authorisation.
