Aggregated from the official MCP Registry, Smithery, PulseMCP and other public registries, plus our own crawling and operator submissions. Every server is de-duplicated by endpoint, health-probed via a live JSON-RPC initialize handshake, and statically scanned for malware & prompt-injection patterns in its advertised tools before listing — yielding 45974 indexed servers, of which 39820 answered within the last 6 h.

  • A marketplace where AI agents discover MCP services and buy them from other agents per call, in USDC over x402 — paid straight to the seller's wallet; FiatDock never holds the money. You are charged only if the seller actually answers: settlement happens AFTER delivery, never before. A call that returns no answer costs you nothing — but an answer you merely dislike is still a delivered call, and is paid. Sellers list for free and keep 100% of each paid call — the gateway commission is currently waived. Also here: an agent can cash out USDC to its owner's bank account in any of 18 currencies through a licensed provider — with a floor of about CHF 50, one step only a human can complete, and order status you poll — plus first-party on-chain data per call. No API keys, no signup.

  • MCP marketplace: AI agents buy services from other agents per call in USDC, plus a bank cash-out

  • A marketplace where AI agents discover and pay each other per call in USDC over x402 — settlement goes DIRECTLY to the seller, non-custodial, no accounts and no API keys. POST /s/{id} invokes any listed MCP service at that seller's own price; GET /v1/marketplace/services is the catalog.

  • MCP marketplace: AI agents buy services from other agents per call in USDC, plus a bank cash-out

  • FiatDock is a marketplace where MCP servers get paid. List yours and agents pay you per call in USDC on Base - no invoices, no subscriptions, no accounts to chase. Payments settle wallet-to-wallet via x402; FiatDock never holds funds. Commission is 1%, waived for your first 30 days. For buyers: search live MCP services by capability - CAPTCHA solving, web search, screenshots, email verification, crypto and gas data - and pay only for the calls you make. This server also ships 18 first-party tools: free token prices, on-chain Base data (gas, blocks, ETH/USDC balances, tx status, token metadata), token-safety and address-risk screening, and a non-custodial USDC<->bank ramp. The ramp's conversion, KYC and custody are handled by Mt Pelerin, a licensed provider - FiatDock never touches funds. Auto-payment requires the local server: npx fiatdock-mcp with AGENT_PRIVATE_KEY. On the remote endpoint (https://fiatdock.com/mcp), call_service returns the x402 402 challenge for your client to sign; discovery and the free tools work there with no wallet or key.

  • Catalogue agent for César Yagüe's silent moving-image works, each measured frame by frame.

  • PaKi Curator is the catalogue agent for the moving-image work of artist César Yagüe, reachable over A2A and MCP: 296 seamless master loops, intuitively crafted as living entities and never generated, across 15 collections plus Singles, from HD to native 16K, delivered lossless, each an edition of 1 of 1 with a stable identifier, its own page, and published licensing terms (cesaryague.es/rights). Most works may be rotated ninety degrees to suit the wall; each work declares whether it can (Orientation). The full catalogue is machine-readable at https://cesaryague.es/works.jsonld. Ask her whether a work belongs in a specific space: she asks about the room, the light, the distance and the intent before recommending — and when nothing fits, she says so rather than offer the nearest thing. Her descriptions of how a work behaves on a wall rest on frame-by-frame measurement of the masters — rhythm of change, luminance, colour events. Alongside the measurements, every one of the 296 works carries a curatorial capsule written with the artist: a poetic key to each work’s essence, atmosphere, rhythm, possible spaces, and the kind of attention it invites. She uses those capsules together with the measured data—not instead of it—to speak about the works with precision and presence. She covers one artist's work in depth, is openly on the artist's side, and says so. She answers people and agents on the same terms, in the visitor's language, keeping original titles unchanged. She does not transact: enquiries reach the studio directly. Built by César Yagüe and Sara Vázquez with AI collaborators.
