"A tool or software for modeling memory systems or memory management" matching MCP servers:

Persistent memory and payment safety for AI agents on Lightning. Enables agents to remember purchases, track vendor reputations, enforce budgets, and share trust signals via Nostr.

Universal HTTP 402 Micropayment Protocol & Autonomous Economic Settlement Engine for AI Agents on Base L2.

Lets coding agents like Claude Code, Cursor, and Codex call MONA Pay directly while developing, so they can create VietQR codes and checkout links, look up incoming transactions, link bank accounts via OTP, and configure or test webhooks (plus email and Zalo notifications) without leaving the editor. It also verifies HMAC-SHA256 webhook signatures offline and generates ready-to-use webhook handler snippets and sandbox transactions for end-to-end payment testing.

A unified MCP server that lets AI agents (Claude Code, Codex, Cursor) deploy web apps and VPS instances, provision Supabase-compatible Postgres/Auth/Storage databases, register DNS domains, and send transactional email using a shared MONA Pass identity and VND wallet. It also embeds MONA Pay tooling for VietQR top-ups, checkout, webhooks and reconciliation, so agents can handle payment requests, budget approvals and resource lifecycles end to end.

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 agents to read recorded payments and request exact refunds for administrator review, then check approval and provider outcome status without holding Stripe credentials or dispatching refunds.

Lets AI coding agents search, reserve and purchase .vn plus 371 international TLDs in VND without leaving the session, including guest reservations before signup. It also handles MONA Pass login, VietQR payment, and attaching DNS/SSL to the app.

Enables MCP clients to access hosted models and services via a local stdio bridge, with live model discovery, pricing, balance checks, and paid execution requiring cost estimates.

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.

Reads and validates any European e-invoice a business receives — XRechnung, UBL, CII, ZUGFeRD/Factur-X PDF, Peppol BIS 3, FatturaPA, KSeF FA(3) — into canonical EN 16931 JSON with plain-language fix hints in EN/DE/PL/IT/FR, plus PDF, CSV and DATEV export. Nothing is stored; works without a key on a small daily quota.

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.

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.

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

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

A paid MCP server that lets AI agents send SMS messages to US phone numbers via x402 micropayments, with automatic compliance and opt-out handling.

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.

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).

MCP server that lets a chatbot browse eSIM plans, sign in, prepare quotes, and execute wallet or card purchases on an existing eSIM platform, with safe typed tools.

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.
