"MCP servers with SSE endpoints" matching MCP servers:

Enables agents and developers to check x402 endpoints, assess scores and wallet risks, authorize payments with spending rules, and report outcomes before an agent pays.

MCP server that preflights endpoints before agent payments, returning a trust verdict with proceed/caution/avoid recommendation.

Enables AI agents to scan payment endpoints for safety, returning a letter grade (A–F) and verdict before authorizing payments.

MCP Server for AI agents to discover and call pay-per-request APIs via EntRoute. Give Claude, Cursor, Windsurf, or any MCP-compatible agent access to 350+ verified x402 API endpoints across 110+ capabilities — DeFi prices, web search, prediction markets, news, and more.

Enables MCP clients to access all endpoints of an x402 gateway by paying real-time microtransactions (USDC on Base) per API call, with automatic tool discovery and spend guardrails.

Exposes all 379 Invoice Ninja v5 REST API endpoints through three consolidated tools (list, describe, call), enabling full invoice management and business operations via natural language.

Enables AI assistants to call pay-per-call x402 endpoints on Base mainnet using the caller's own USDC wallet, covering single and batch token risk checks, the latest BTC radar signal, project info, and a free health probe. Payments are EIP-3009 signed with a configurable per-call spending cap, and any quote with an unexpected payee, network, or asset is refused before payment.

Before an AI agent pays an x402 endpoint, checks whether it's safe to pay: liveness, scam/anomaly scan (payTo hijack, bait-and-switch, honeypot), and on-chain receiver verification. ~70% of x402 endpoints are dead or scams.

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

Enables AI agents to call x402-gated APIs using a central credit balance, abstracting away blockchain complexity and payment proofs. It provides tools to fetch data from payment-required endpoints, check usage balances, and simulate transaction costs.

Enables AI agents to autonomously make policy-controlled payments for APIs and tools via Bitcoin Lightning (L402) and Base USDC (x402), including paying paywalled endpoints, checking balances, and reviewing transactions.

Enables Claude to interact with a Folio business bank account for managing accounts, transactions, receipts, bookkeeping, and payments as drafts.

Lets AI clients call paid x402ai endpoints — embeddings, summaries, and short answers — paying per call in USDC on Base via the x402 protocol, with per-payment and per-session spend caps plus a free inspector for decoding any x402 endpoint's payment challenge. Runs locally over stdio, needs no hosted account, and can operate in quote-only dry-run mode.

Enables to generate, decode, and validate PayBySquare QR codes for Slovak payments, with MCP integration for use with Claude Desktop and other MCP clients.

Self-custodied Nano wallet + x402 payment client and merchant server for AI agents, enabling micropayments, on-ledger settlement, and paid endpoints.

Search and route across ~20,000 live x402 pay-per-call API endpoints on Base and Solana USDC

Enables AI assistants to manage a LearnWorlds school via the full public API, covering all 94 endpoints for courses, users, enrollments, payments, and more.

Connects AI agents to Bitcoin payment rails with owner-defined spending policies and limits.

Lets AI agents discover and call the SelectaRank Data Gateway's paid endpoints—earthquake, weather, World Bank, and x402 preflight—as MCP tools. When a wallet key is configured, per-call fees are paid automatically in USDC on Base, with an optional price cap; without one, calls return the 402 payment requirements instead.

Enables LLMs to interact with Billforward's billing and subscription management API, providing tools for accounts, subscriptions, invoices, payments, and more with read-only safety by default.

Enables AI assistants to interact with Investec banking accounts, transactions, payments, and programmable cards through natural language.

Client-side MCP wrapper for Orisha Data's public x402 endpoints, providing free preview tools and paid market data access via x402 payments.

This Model Context Protocol server exposes the Wafeq Public API — all 251 endpoints, generated straight from the OpenAPI spec into MCP tools, plus two hand-written ones. Every tool carries a safety category (🟢 read-only / 🟡 write / 🟠 state change / 🔴 irreversible or destructive) so your assistant knows what an action does before it calls it — including the difference between saving an invoice
