"Exploring Computer Usage" matching MCP servers:

Pay-per-call USDC payment proxy for AI agents. Issue scoped Pay Tokens with hard spending caps and auto-journal every charge to freee / Money Forward / QuickBooks.

Enables querying OpenCode Go subscription quota (rolling, weekly, and monthly usage) and Zen prepaid balance as MCP tools.

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.

Integrates usage-based billing into AI coding tools, enabling meter usage, signal verification, and billing management via the ClockNext API.

eSIM data plans for 200+ countries: search wholesale plans, check balance and usage, diagnose eSIM connectivity from live network data, and (opt-in) order and top up eSIMs with a confirmation step.

Stateless HTTP MCP service that exposes the Pax8 Partner API as tools for AI assistants to query companies, subscriptions, invoices, orders, products, and usage data.

Universal billing gateway for MCP servers. Add Stripe subscription billing to any MCP server with one line of code. Supports tiered plans, usage tracking, and automatic access control.

Connects AI agents to Revenium for cost tracking, alerting, and usage-based billing, enabling AI assistants to manage costs, set alerts, and handle billing operations.

Enables AI agents to manage subscriptions, usage-based billing, payments, refunds, tax compliance, and invoicing to drive revenue growth.

An MCP server that acts as a secure, multi-tenant proxy to the InvoiceShelf API, enabling AI assistants to manage invoices, estimates, customers, payments, expenses, and more with 109 tools and TOON compression for efficient token usage.

Enables pay-per-call access control for AI agents using HTTP 402 and on-chain settlement, allowing microtransactions for API usage.

MCP server for AI agent billing. Preflight spend checks before agent runs. Post-execution usage billing via two MCP tools: preflight() and record_event().

Deploy and monetize agent-built apps from one MCP. Ship a full-stack app (login, database, usage billing) with one command, then charge the signed-in end user per API call via X-Settle-Payer (end-user-pays: cost times markup, app owner earns the markup).

Template for creating MCP servers with a server-side paywall gate, enabling free local usage and premium hosted tier with Stripe and x402 payment lanes.

Usage tracking and credit/quota access-gating for enlace MCP connectors, providing policy-based metering with ledger recording and fail-closed FastMCP middleware to enforce per-principal credit and call caps.

Enables diagnosing Metronome usage-billing issues by inspecting events, running deterministic checks, and drafting customer replies through natural language in Claude Code.

Enables registering cards, upserting offer rules, recording transactions, and getting deterministic reward recommendations and cap-usage status for Taiwan credit cards over stdio JSON-RPC.

A production-ready template for building monetized MCP servers that require per-call payments via the Mainlayer infrastructure. It provides a structured payment gate that ensures AI agents pay for tool usage before accessing server logic or data.

Enables micropayments for MCP tool invocations using the X402 payment protocol, allowing servers to charge per tool usage in USDC and clients to automatically handle payments.
