23-in-1 MCP server: EVM tx simulator, funding rate arb, macro radar, swap calldata & security.
Pay-per-call remote MCP server bundling 24 crypto, security, research and B2B intelligence tools settled in USDC on Base via x402.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.ralf9090%2Fagent-kiosk/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}[x402 v2 Base Mainnet] [Smithery MCP Server] [ralf9090/agent-kiosk MCP server]
Agent Kiosk is an instant pay-per-call API and Model Context Protocol (MCP) server built for autonomous AI agents, trading bots, coding assistants, and research workflows on Base Mainnet (eip155:8453). Every paid and prepaid response includes a cryptographic SHA-256 + HMAC-SHA256 attestation envelope (attested tag).

Unauthenticated requests return HTTP 402 Payment Required with the PAYMENT-REQUIRED header.
eip155:8453)$0.00 USDC — HTTP 200 without x402 payment)Agent Kiosk verifies and settles incoming EIP-3009 (TransferWithAuthorization) USDC signatures on Base Mainnet (eip155:8453 / base) using a multi-facilitator failover pipeline configured in src/x402.js:
payTo): 0xd8429209Aee6A398B9707DFf5F28AAA93452eE95 (Base Mainnet USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, 6 decimals).402 Payment Required challenge specifies maxTimeoutSeconds: 60. Buyers should sign EIP-3009 TransferWithAuthorization messages with validAfter = 0 and validBefore >= now + 300 seconds.POST /verify and a 10.0-second timeout per facilitator on POST /settle.facilitator.payai.network) returns an HTTP/network error on /verify or /settle, the middleware automatically fails over to the next configured facilitator (facilitator.dexter.cash). If a signature is cryptographically invalid (invalid_exact_evm_signature), the server immediately returns HTTP 402 with the exact error reason without retrying.TransferWithAuthorization uses a unique 32-byte nonce. Once consumed on Base Mainnet, the USDC contract (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) permanently marks that (authorizer, nonce) pair as used (AuthorizationUsed event), making replay or double-charging of the same signature impossible on-chain.PAYMENT-SIGNATURE, do NOT immediately sign a new nonce:
0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) via authorizationState(address authorizer, bytes32 nonce) (0xe94a0102) or check https://basescan.org/address/0xd8429209Aee6A398B9707DFf5F28AAA93452eE95#tokentxns.authorizationState is false (not settled on-chain): You can safely retry the request using the exact same PAYMENT-SIGNATURE header (same nonce) until validBefore expires, or wait for validBefore to pass before signing a new nonce.authorizationState is true (settled on-chain, but HTTP response was lost in transit): Open an issue at github.com/ralf9090/agent-kiosk/issues with the Base txHash, endpoint path, and timestamp for immediate response replay or a complimentary Prepaid API Pass credit.Disclosure: The transactions below are operator test payments executed against the live production deployment (
