"browser tool" matching MCP servers:

x402-trust gives AI agents a "check before you pay" layer for the x402 ecosystem.

Create free, no-signup invoices from your AI assistant — the create_invoice tool returns a link that opens blankinvoicemaker.com pre-filled, ready to download as a watermark-free PDF.

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.

Automates Spectrum/Charter ISP account management tasks such as viewing account overview, paying bills, checking outages, and scheduling technician visits via browser automation.

MCP server that gives Claude/GPT agents commerce tools — each tool call pays an upstream x402 endpoint and returns its artifact.

Enables individual proprietors and freelancers to manage daily accounting tasks like journal entries, invoice creation, and monthly reconciliation through simple tool calls, using freee's API.

An MCP server that enables AI assistants to automate Cash App payments, balance checks, and transaction management via browser automation.

Read-only MCP server for the Swiss eBill portal, enabling users to list bills and download invoice PDFs via an authenticated browser session. It cannot approve, release, or pay anything.

Enables running a local MCP server for Poland's KSeF (Krajowy System e-Faktur) e-invoicing system, so invoice data stays on the user's own machine rather than passing through an intermediary service. It currently exposes only a diagnostic server_info tool, with invoice search and retrieval tools still to come.

Enables agents to play the Crowns medieval world game through tool calls instead of composing raw HTTP requests. It handles x402 USDC payments from the agent's own wallet, letting the model claim land, build, trade, and wage war.

Deprecated browser-automation MCP server for Venmo, PayPal, and Cash App (withdrawn due to ToS violations, account suspension risk, and credential exposure). Do not use.

Enables MCP tool developers and AI agents to track payments, calculate sales tax liability, and ensure tax compliance across US jurisdictions.

Enables interaction with the Crowns game API as MCP tool calls, including x402-based payments.

Enables clients to issue refunds over stdio through a JSON-RPC tool call backed by a ledger. Malformed arguments are rejected with a real -32602 error code instead of the SDK's default isError result.

One install for the whole freelancer office. This MCP server proxies four sibling servers -- time-tracker, price-tracker, spreadsheet and invoice -- so a client gets every tool from all four behind a single config entry instead of four.

Enables AI agents to access DDG's payable services including checkout/payment conformance, MCP/tool security audits, agent-discovery repair, and buyer-agent smoke probes, with structured payment challenges.

Enables AI agents to interact with the BulkClix platform for SMS, OTP, airtime, mobile money, bank transfers, data bundles, KYC, contacts, and account management via natural language.

agenticpay lets MCP server developers monetize tools via per-call USDC micropayments on Solana, using the x402 protocol. Each tool declares a price; agents pay via signed Solana transactions; settlement happens on-chain in ~1.5–2 seconds.

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

Generic Lightning-paywall sidecar that wraps any stdio MCP server and requires a paid Lightning invoice (via NWC) before forwarding priced tool calls. Per-tool prices are set via env; includes payment verification, replay protection, and an audit log — the upstream server stays untouched.
