"Actual Budget" matching MCP servers:

Manages agentic workflow spend through budget quotes, policy gates, approvals, receipts, and cost evidence exports.

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.

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.

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.

A budget-bound x402 payment wallet for AI agents: it autonomously pays HTTP 402 payment-gated URLs across every major chain (EVM, Solana, and many non-EVM families). Self-custodial and backendless, your key, your RPC, with spend caps enforced before any on-chain send.

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

Budget, approval, and receipt layer that agents call when they buy on a human's behalf. MCP server with dry-run by default.

MCP server exposing a Lightning wallet to LLM agents over Nostr Wallet Connect (NIP-47): balance, invoices, LN address/LNURL payments, batch pay, and keysend. All spend tools are wrapped in a defense-in-depth safety stack — budget caps, allowlist, two-step confirmation, audit log.

Enables AI agents to search merchant catalogs, verify product prices and stock, and create purchases with budget limits and human-in-the-loop approval in Russian specialty stores.

Let your AI assistant pay for web content in USDC (x402 on Base) within a budget you set. Inside the budget it pays on its own; above it you are asked to confirm. The wallet key stays on your computer. For claude.ai and ChatGPT there is a remote server (https://agent.p2flux.com/mcp) where you approve each payment in your own browser wallet.

AI payment guardrails for Python & MCP: spend-capped agent identity (KYA), dry-run/budget/approval gates, prompt-injection defense, encrypted secret vault.

Enables AI agents to search fireworks by technical specifications and budget, check stock availability, locate Nova Poshta branches and parcel lockers, and place orders with secure Monobank online checkout.

Lets any MCP-compatible agent shop for catalog items by SKU and quantity under a user-set budget, category and expiry limit. Purchases flow through deterministic server-side pricing, policy checks, single-use approval binding and a recoverable execution state machine, so a compromised or manipulated model cannot move money.

NexaLayer MCP Server — a Model Context Protocol server that lets AI agents create and manage dynamic and static proxy sessions with budget guardrails.

Enables agents to autonomously pay x402 API requests in USDG on Robinhood Chain while enforcing budget caps and scoped sessions.

Enables autonomous multi-person group food ordering on Swiggy by solving dietary, budget, and delivery-SLA constraints to pick a restaurant and allocate dishes, then consolidating the items into a single cart. It also computes exact proportional bill splits including taxes, fees, and discounts, and generates UPI payment links for reimbursement.

Enables agents and apps to verify end-user identity through company API keys, human login links with multi-channel notifications, OIDC client registration, and budget-aware billing.

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.

Enables agents to sell MCP tools and Hermes capabilities behind an x402 v2 / USDC payment gate, and to buy other agents' capabilities through a wallet tool. Sellers quote a price, verify the exact transfer and nonce, then execute, while buyers get recipient allowlists, per-call limits, and a persistent cumulative budget.

A one-command paywall for local servers that enables testing AI agents' payment flows by simulating HTTP 402 Payment Required responses. It proxies requests with valid payment headers to the actual server, making it easy to develop and test x402 client logic without real blockchain transactions.
