Enables AI assistants to extract invoice data from existing PDFs and create EN 16931-compliant ZUGFeRD/Factur-X e-invoices or XRechnung XML locally, without uploading documents.

Enables AI agents to inspect a single inbound email and receive structured findings such as kind, verdict, scores, and named checks, along with checking or buying prepaid credit. It never writes replies, connects to inboxes, or sends mail.

Keyless crypto payments for AI agents. One MCP call turns any wallet address into a non-custodial crypto payment link or tip jar, no API key and no account, with funds settling straight to your wallet at a 0% platform fee (USDC/USDT, BTC, LTC, DASH, DOGE, ZCASH).

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.

MCP server that gates API calls to AI agents using proof-of-work (free) or Lightning payment (3 sats), providing challenge, verify, and status tools for per-call authentication without accounts.

Enables AI agents to call paid APIs and settle HTTP 402 payment challenges with USDC on Base, without private keys ever being involved.

Check, convert and explain Factur-X / ZUGFeRD e-invoices from your AI assistant: validate a PDF against EN 16931 or the French 2026 rules, dry-run or convert an invoice to Factur-X, and get a plain explanation of any validation error.

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.

Enables AI agents to draft AP-style press releases from a product URL and publish them to a public newsroom page, or distribute them across a newswire to hundreds of news, TV and radio sites, with status tracking for wire orders. Paid calls are settled per request in USDC on Base via x402 from the user's own wallet, defaulting to quote-only mode with spend caps and confirmation tokens.

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 natural-language interaction with Splitwise to explain balances, find missing or duplicate expenses, plan settlements, and safely add expenses with confirmation.

Generate crypto QR codes (BTC, ETH, SOL, USDC, USDT, EURC) and manage payment sessions from Claude Desktop or any MCP client. Non-custodial, free.

Enables issuing credit notes and credit memos against an invoice or standalone as revisable drafts that can be finalized into frozen numbered documents, then rendered as Markdown or printable HTML with totals broken down by currency, reason and month. All amounts are handled as integer minor units and all data stays local, so nothing is sent anywhere.

Enables AI assistants and agents to vet a stablecoin or x402 payment before it is sent, returning an approve, hold, or reject decision from instant rule checks and an optional locally-run risk model. Fails closed, so malformed input or an unreachable model yields a hold rather than an approval.

A local MCP server that integrates ProofJSON to assess invoices before payment, providing allow/review/block decisions with confidence scores and verification capabilities.

Create invoices from any MCP client via the Invovate API — compute totals and generate PDF, JSON, or UBL invoices in 11 languages. Exposes four tools: calculate_invoice_totals (no API key needed), generate_invoice_pdf, generate_invoice_ubl, and get_invoice_capabilities.

Enables AI clients to check an application balance and preview or send bulk SMS and airtime, either through a hosted OAuth connection that needs no local install or via a self-hosted stdio/Cloudflare Workers deployment using your own credentials. Sending is preview-only by default and gated behind environment, recipient allowlist, and mutation opt-in settings.

Lets agents query anchored ground-level capture data, verify provenance, and commission new captures, paying per request in USDC on Base or Arc via x402.

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.

Enables agents to cash out USDC on Arc into a Nigerian bank account by saving a verified payout recipient once and reusing it, quoting exact NGN amounts or USDC budgets, and executing approved payouts with status tracking. Balances, rates, and bank payouts are simulated in the current demo rather than settled on-chain.

Enables MCP clients to work with Wave invoicing for a single business, including looking up customers and invoices, creating customers and draft invoices, and approving, sending, or recording payments behind a preview-then-confirm step.

Enables users to track unpaid invoices and generate an escalating ladder of payment-reminder letters — first reminder, second reminder, and final notice — anchored to the due date, plus overdue listings, aging buckets, and a daily chase list of what to send today. It records payments and letters sent, rendering each letter as Markdown or printable HTML without ever emailing anything itself.

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.

Enables AI agents to call 33 pay-per-call tools for onchain data, ECB exchange rates, text utilities, and more, using USDC on Base over x402 with optional prepaid credit or wallet-based payments.

Enables building client statements of account from existing invoices, credit notes, and deposits, with aged outstanding balances, PDF/plain-text output, and drafted payment chasers at friendly, firm, or final levels.

Connects an AI assistant to a BuchhaltungsButler tenant through 59 German-language tools — 54 endpoint tools (one per API v1 endpoint) plus 5 bundle tools — covering documents, payments, invoices, postings, master data, cost centers, and reports, of which 19 are read-only. Runs locally, so credentials go only to BuchhaltungsButler itself, and lets users control in their client which tools the assistant may call.

Enables a shopping agent, before it pays, to determine which of the user's cards to charge, which statement credit applies, and whether that credit has already been used or is about to expire. It also flags payment-rail risks that could prevent merchant credits from triggering, and tracks card, credit, and balance details locally as the user provides them in conversation.

Non-custodial x402 payments between AI agents on Solana. Tools that move funds return unsigned transactions; m2m.monster holds no agents' keys or funds and never signs or pays payment transactions.

Enables AI agents to create stablecoin payment links with QR codes and hosted checkout pages, and to check, list, validate or delete payments across Stellar, Solana and Monad using an API key. Read-only mode, scoped keys and tool annotations keep fund-moving and destructive actions under user control.

Enables MCP clients to browse and purchase agent packages and pay per call for model inference on Robinhood Chain using USDG, with no account or API key required.

Runs locally over stdio with the user's own API key and is read-only by default.
