"browser tool" matching MCP servers:

Signed, independently verifiable Ed25519 receipts for autonomous AI agent calls; every session returns a receipt link anyone can check in the browser, no account.

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.

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.

Decodes HTTP 402 challenges into exact payment and retry steps, recommends a payment rail from stated requirements, and searches an open registry of scored payment solutions with scheme references and support probing. Every tool is read-only, so nothing can spend money.

MCP server for the Hosannaith x402 reliability oracle on Algorand. Gives any agent a tool to score an x402 endpoint's reliability — uptime, correct HTTP 402 behaviour and latency — before paying it.

Enables AI agents to create and wait on Ethiopian birr checkouts, manage products and orders, preview and (when explicitly enabled) send payouts, verify and test webhooks, and search Jami's documentation. Every tool mirrors the official JamiDev SDK and REST API, with money handled as integer santim and withdrawals gated behind opt-in flags.

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

Let your AI assistant pay for web content in USDC (x402 on Base) within a budget you set. Inside the budget it pays on its own; above it you are asked to confirm. The wallet key stays on your computer. For claude.ai and ChatGPT there is a remote server (https://agent.p2flux.com/mcp) where you approve each payment in your own browser wallet.

Enables an MCP client to answer revenue questions about a Stripe account — normalized MRR/ARR, subscription and customer churn, failed payments and a one-call revenue summary, all grouped per currency. Access is read-only and a built-in deterministic demo dataset lets every tool be tried without a Stripe API key.

Provides read-only access to a therapy practice's client portal, letting users view upcoming appointments, paperwork requests, standing forms, balances, receipts and secure message threads, and download completed documents and payment receipts as PDFs. It authenticates either with server-side credentials or by relaying requests through the user's already signed-in browser tab, and never sends messages, signs forms, uploads files, or makes payments.

Enables Brazilian developers to validate CPF/CNPJ documents and boleto digitable lines, generate and verify static Pix BR Code payloads with CRC16, compute Price-table installment schedules, and locate a salary within configurable pay bands. It also exposes a tool catalog resource and a billing-check prompt that ties document and Pix verification together.

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 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.

Non-custodial stablecoin bill payments (airtime, data, electricity, cable, education) on Celo mainnet, reachable via x402 (zero setup, EIP-3009), a linked wallet's PIN-gated MCP/A2A tool catalog, or plain natural language on Telegram/WhatsApp/X.

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