"Information about Unreal Engine" matching MCP servers:

A standard MCP server for discovering AI agents and negotiating signed skill contracts. Buyer-seller payments are settled directly outside the platform; Agent Economy Engine collects only a platform fee after both parties attest completion.

Enables querying MRR, churn, and revenue from Stripe, Gumroad, and Lemon Squeezy directly inside Claude, allowing natural language questions about business metrics.

Gives your agent a private Kinematic Drive: a deterministic memory engine for sub-millisecond exact recall over code and docs with no hallucination. Also provides self-serve checkout and metered pay-per-call tools for AI agents.

Enables an MCP client to answer revenue questions about a Stripe account — normalized MRR/ARR, subscription and customer churn, failed payments and a one-call revenue summary, all grouped per currency. Access is read-only and a built-in deterministic demo dataset lets every tool be tried without a Stripe API key.

Connects AI assistants to Quaderno's tax compliance engine, enabling tax calculation, tax ID validation, and invoice creation via natural language.

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

Enables users to connect bank accounts within a chat session using Sophtron's UCW widget and query account information, owner details, and transactions persistently.

Enables AI assistants to read Itaú bank account information (balances, statements, credit card bills, investments) via Open Finance Brasil, read-only.

Enables AI agents and finance teams to extract structured fields from messy invoices and audit them before payment, applying seven evidence-backed risk rules that catch total/tax mismatches, duplicate invoices, missing fields, future dates, and round amounts, then returning a 0–100 score with a payment link. Exposes four MCP tools over stdio and Streamable HTTP (spec 2025-11-25) plus a web UI, backed by an optional AWS Bedrock or OpenAI-compatible extraction brain that degrades gracefully to a zero-dependency offline engine.

Connects Mercado Pago accounts via Open Finance Brasil to AI assistants for read-only queries about balances, statements, credit card bills, and investments.

Exposes the full HelloAsso v5 API — memberships, tickets, donations, payments, refunds and checkouts — to any MCP client as 36 tools plus summaries, so assistants can resolve organizations, forms and periods from plain URLs and natural language and answer questions about an association's finances. Money-moving operations are guarded behind explicit confirmation and an optional read-only mode.

Enables AI agents to retrieve and analyze Dwolla payment platform data using natural language, with read-only access to accounts, transfers, customers, and compliance information.

MCP server that validates semantic version ranges using npm's semver engine, with payment via x402 on Base mainnet.

Connects PagBank accounts to AI assistants via Open Finance Brasil, enabling natural language queries about balances, statements, credit card bills, and investments. Read-only and regulated by the Central Bank.

Non-custodial payment engine for AI agents supporting BTC, ETH, USDT, USDC, XRP, XMR, and ZEC. Exposes wallet, invoice, and payment tools over MCP with per-agent spend limits, plus x402 pay-per-call support.

AI-powered personal finance analysis through Claude AI using Plaid integration, enabling natural language queries about transactions, subscriptions, budgets, and spending trends.

Exposes Charles Schwab brokerage data to AI assistants via MCP, enabling natural language queries about positions, option chains, account balances, and trade audits with Lightning micropayment monetization.

Exposes Recapfy's paid endpoints as MCP tools to ask questions about YouTube videos and fetch full transcripts, with automatic USDC payment on Solana per call.

Enables natural language queries about Porto Bank accounts via Open Finance, including balances, statements, credit card bills, and investments, using Claude, ChatGPT, and AI agents.

Enables store owners to reorder from suppliers by voice or chat and settle payments through PayPal, while a deterministic policy engine enforces spending limits, allow-listed suppliers, price-jump and duplicate checks so the LLM can only propose payments, never move money. Funds are authorized rather than charged, then captured only for goods verified on delivery via a 3-way match, with step-up human approval for unusual orders and a full audit ledger of every authorization, capture, void and refund.
