"Figma – Collaborative Design and Prototyping Tool" matching MCP servers:

Discover audio and LLM services, compare seven voices, and check prices for free. Generate speech, transcribe audio and request LLM text with optional capped USDC payments on Base; voice-cloning requirements are also available.

Credit and payments for AI agent developers — over MCP. No crypto required

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

Enables running a local MCP server for Poland's KSeF (Krajowy System e-Faktur) e-invoicing system, so invoice data stays on the user's own machine rather than passing through an intermediary service. It currently exposes only a diagnostic server_info tool, with invoice search and retrieval tools still to come.

Create free, no-signup invoices from your AI assistant — the create_invoice tool returns a link that opens blankinvoicemaker.com pre-filled, ready to download as a watermark-free PDF.

MCP server for real FDM 3D-printing slicing, quoting, and design-for-manufacturability analysis via the FabTally API, supporting 12 printer profiles and 12 materials. Includes free discovery/printability tools and paid slice/quote/orientation tools settled via x402 (USDC on Base).

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.

MCP server that gives Claude/GPT agents commerce tools — each tool call pays an upstream x402 endpoint and returns its artifact.

Enables individual proprietors and freelancers to manage daily accounting tasks like journal entries, invoice creation, and monthly reconciliation through simple tool calls, using freee's API.

Enables agents to play the Crowns medieval world game through tool calls instead of composing raw HTTP requests. It handles x402 USDC payments from the agent's own wallet, letting the model claim land, build, trade, and wage war.

Non-custodial stablecoin bill payments (airtime, data, electricity, cable, education) on Celo mainnet, reachable via x402 (zero setup, EIP-3009), a linked wallet's PIN-gated MCP/A2A tool catalog, or plain natural language on Telegram/WhatsApp/X.

Enables MCP tool developers and AI agents to track payments, calculate sales tax liability, and ensure tax compliance across US jurisdictions.

Enables interaction with the Crowns game API as MCP tool calls, including x402-based payments.

Enables AI assistants such as Claude, ChatGPT and Cursor to manage an open-source subscription backend: setting up products, entitlements, offerings and packages, looking up customers, granting or revoking access, adding webhooks, and tracking RevenueCat imports. Tool names mirror RevenueCat's MCP tools, so existing prompts work unchanged.

Enables clients to issue refunds over stdio through a JSON-RPC tool call backed by a ledger. Malformed arguments are rejected with a real -32602 error code instead of the SDK's default isError result.

Enables AI agents to hold XNO and make feeless, instant per-API-call payments via the public rpc.nano.to node, including wallet management, paid tool execution, and a self-hostable x402 payment facilitator.

Enables AI agents to hold Nano (XNO) and pay per API call through a public node, providing wallet operations and pay-per-call tool access.

Enables AI agents to access DDG's payable services including checkout/payment conformance, MCP/tool security audits, agent-discovery repair, and buyer-agent smoke probes, with structured payment challenges.

One install for the whole freelancer office. This MCP server proxies four sibling servers -- time-tracker, price-tracker, spreadsheet and invoice -- so a client gets every tool from all four behind a single config entry instead of four.

Enables Claude to read UK bank account data—balances, transactions, cards, standing orders, direct debits, and identity—through TrueLayer's Data API, with local caching and optional live refreshes. It is read-only by design, requiring consent and never moving money.
