"How to conduct web searches" matching MCP servers:

A shopper’s agent searches stores, compares prices and buys with the shopper’s approval.

Enables AI agents to discover and pay for x402-gated HTTP APIs, handling 402 Payment Required flows with local signing. Supports EVM and Solana with non-custodial wallet management.

A local, read-only stdio MCP server that lets a Grok Build CLI agent check how much of its weekly SuperGrok / Grok Build usage pool is left, when the period resets, and its Extra Usage cap via tools like get_budget. It reads the existing grok login session and returns per-product figures as JSON, mirroring the TUI /usage screen, so agents can pause before expensive work when quota runs low.

A read-only MCP server for the open-banking.io PSD2 API that lets AI agents query personal bank balances and transactions via natural language, with zero-knowledge encryption ensuring all sensitive data is decrypted in-process and never exposed to third parties.

Official MCP server for PushNotif.biz.id. Enables AI agents to register websites, generate one-line SDK snippets, and broadcast or schedule Web Push (VAPID), Android FCM, iOS APNs, In-App Popups, Live Activity Toasts, and automated RSS push notifications with real-time CTR analytics.

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.

Structured product data from the open web — where platform APIs don't reach. Schema.org + AI extraction. Pay per call via Stripe MPP.

Provides AI agents with SSRF-protected URL intelligence and 32 paid REST/MCP tools, plus a free catalog search, with payments in USDC on Base Mainnet.

Non-custodial USDC <-> bank for AI agents. Free quotes; $0.05 USDC per session via x402; 1% commission itemised in every quote. Own funds only. PT + EU/EEA (not UK). 18+.

A recoverable Firecrawl MCP server that adds payment lifecycle, idempotency, and automatic refunds/fallbacks to web scraping, enabling reliable paid scraping via natural language.

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.

A Model Context Protocol server that executes headless web scraping and ephemeral secret vaults, settling micro-transactions natively on Base Mainnet via the x402 protocol.

Lets AI agents buy Bacon Services image operations (remove background, optimize for the web, colour palette, brand kit from a URL) per call in USDC on Base over x402, paid from the user's own wallet with local spending limits.

Buy at cash-only or unsupported shops by paying crypto (BTC signet, USDC) to a proxy shopper through a 2-of-3 escrow with timelocks over Nostr, or earn as a proxy shopper. Tools that move money act only with confirm: true.

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 users to access transaction reports and exports, create payment links, and optionally match payments to a payer roster workbook through an MCP interface.

Lets an MCP client find overdue Stripe invoices, see who owes what and how late they are, and re-send reminder emails for invoices that are still open. Runs read-only unless writes are explicitly enabled, re-checks invoice state before sending, and logs every call to an audit trail.

Enables AI agents to spend with the user's own key by paying via USDT TRC-20 and buying Visa/Mastercard prepaid cards, travel eSIMs, and gift cards, and also provides access to policy and how-to documentation.

Enables any MCP client (Claude, Cursor, Windsurf) to commission IMD's agent swarm for websites, sourced reports, code audits, images, smart-contract projects and oracle questions. A built-in saver searches already-shipped work, requires IMD's free pre-check, blocks duplicates, enforces per-order and daily hard caps, and waits for explicit confirmation, so agents can browse and draft for free while paid orders stay bounded and recoverable.

Pay-per-use semantic web search for AI agents. Powered by SearxNG, agents pay in sats via Lightning Network micropayments — no API keys required.

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

Enables users to access a free catalog and samples plus 17 pay-per-call tools, settled in USDC on Base via x402, for web reading, source-bounded summarization, Rioplatense Spanish translation, market and Argentine data, developer utilities, text comparison, and x402-related queries.

Enables Claude Code to access and query the lk-tko-v2 personal account system through MCP tools, including checking contragent status, debts, contracts, and billing data via REST APIs.

Enables AI agents to issue, void, query, and manage Taiwan e-invoices via 27 MCP tools, wrapping the Universal EC POS Web Service.

Enables AI assistants to pay for online purchases and subscriptions using one-time prepaid USD Visa cards drawn from the user's own wallet. Every charge requires explicit user approval, and each card is loaded with only the needed amount and freezes after a single payment.

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.

MCP server to connect AI assistants to the AdvinPay payment API, enabling PIX charges, transaction queries, and documentation search.

Connects MCP clients to a telephony account so users can manage phone numbers, SIP accounts, routing, SMS, calls, and billing in plain language. It exposes search, schema lookup, and execute tools to run permitted API operations, with confirmation required for paid or destructive actions.

Enables AI agents to interact with the Griffin API for banking operations like opening accounts, creating payments, and managing legal persons.

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.
