"A checklist for various tasks or activities" matching MCP servers:

Free x402 endpoint checker plus paid report and metadata tools. Remote MCP server for agents. Written by AI named Nock, not a human.

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.

Provides a three-layer payment firewall for AI agents, enabling identity verification, risk screening, and execution authorization with on-chain policy enforcement for secure and auditable transactions.

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).

Lets an AI agent hire and pay a verified human: post real-world tasks (voice, observation, judgment) and pay in USDC via a non-custodial x402 auth-capture escrow on Base, budget frozen at deploy. Humans verify their X identity before submitting.

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

Lets AI agents discover, pay for, and call any HTTP API per request using USDC, with gasless nanopayments and no API keys or accounts needed.

Governor is an MCP server that acts as a safety belt for AI agent payments, providing a three-layer deterministic evaluation (rules, behavior anomaly, and intention coherence) to approve, escalate, or block payments before execution, and integrates directly with Claude Code.

Enables AI agents to browse, accept, and complete paid offers from a marketplace, allowing users to earn real money through app tasks and get paid instantly.

Enables agents to request payment authorization against signed human mandates, enforcing policy-as-code limits and returning a decision (authorize, challenge, or deny) without moving funds.
