"How to make a model aware of the current time before thinking" matching MCP servers:

MCP server that verifies storefront merchants before AI agents make payments, checking if the merchant is a real legal entity bound to the domain, and returning a PROCEED, ABORT, or REVIEW decision to prevent payment to clones or fraudulent stores.

A minimal demo of the x402 payment protocol protecting an MCP tool endpoint, showing how to charge for MCP tools using real 402 rejections and testnet payments.

A pre-payment safety gate for x402 that screens payment metadata for PII, enforces spending policies, and detects replay attacks before signing.

Enables AI coding assistants to log billable hours into the Keeping time-tracking service via MCP tools, with dry-run protection for all write operations.

x402-trust gives AI agents a "check before you pay" layer for the x402 ecosystem.

Connects Claude to the customer side of Housecall Pro, letting you view estimates and invoices, check company details, and decline estimate options using the link your contractor sent.

MCP server that preflights endpoints before agent payments, returning a trust verdict with proceed/caution/avoid recommendation.

An MCP server that provides programmable spend limits and audit trails for AI agents to make payments from a dedicated wallet, preventing overspend and unauthorized transactions.

Enables AI agents to scan payment endpoints for safety, returning a letter grade (A–F) and verdict before authorizing payments.

Provides currency conversion using the Wise API, supporting real-time and historical rates with caching and cross-rate calculation.

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.

Enables AI agents to gate real-world side effects through a durable decision record, ensuring at-most-once initiation, deduplication, budget enforcement, and auditable outcomes across retries and failures.

Enables AI agents to make payments with strict spending limits enforced by signed mandates, preventing unauthorized fund movement beyond predefined caps and allowlists.

Payment firewall for AI agents: a signed, independently verifiable verdict on every money-moving action. Blocks wrong/lookalike payee, over-cap, and duplicate-invoice (BEC) fraud before money moves — anyone can verify a verdict against the public JWKS. Free, local-first, non-custodial.

Payment infrastructure MCP server enabling AI agents to make gasless USDC payments on Base and JIT single-use virtual card checkouts, with zero-trust card handling, merchant checkout hints, and signed receipts.

Before an AI agent pays an x402 endpoint, checks whether it's safe to pay: liveness, scam/anomaly scan (payTo hijack, bait-and-switch, honeypot), and on-chain receiver verification. ~70% of x402 endpoints are dead or scams.

AI-native payment infrastructure that enables AI agents to make purchases, issue virtual cards, and manage spending within delegated budgets and policy controls.

Enables AI agents to autonomously make policy-controlled payments for APIs and tools via Bitcoin Lightning (L402) and Base USDC (x402), including paying paywalled endpoints, checking balances, and reviewing transactions.

MCP server providing access to the easybill REST API for managing invoices, customers, articles, payments, projects, and time tracking, with read-only mode by default.

Enables agents to search a verified directory of machine-payable services, inspect service and wallet reputation, and get pre-payment checks before spending.
