Pre-alpha TypeScript infrastructure for paid MCP tools using Solana USDC and x402, including SDK, CLI and a self-hosted facilitator. End-to-end validation is on devnet; mainnet configuration requires real funds and suitable RPC infrastructure.

Wraps the Circle CLI as MCP tools for wallets, spending policies, USDC transfers and x402 payments. Requires an installed authenticated Circle CLI and spending credentials; transfers can move real funds.

Self-hosted gateway that adds x402 micropayment gates to APIs and MCP tools. Live settlement needs facilitator credentials and funding; the primary production fee-splitting path is Base USDC, while other networks vary in readiness.

Implements quote negotiation and HTLC settlement workflows for cross-chain testnet trades. Supports local signing or remote unsigned transactions; mainnet trading is not supported.

Provides token balances, DeFi quotes and unsigned EVM transaction construction through MCP. External signing is supported; configuring a private key enables actual transaction execution.

SDKs, payment clients and MCP tools add per-call Lightning/L402 payments and gateway verification to agent commerce; payment use needs a compatible wallet and funds, while the hosted platform remains separate from these public packages.

MCP tools discover ERC-8004 agents and optionally call them with automatic x402 wallet payments; discovery is keyless, but payment needs a private key and registry payment-support flags are self-declared, not verified availability.

A local MCP adapter creates cryptocurrency payment QR codes and hosted stablecoin payment sessions and checks their status; it requires a Toreador Pro API key and cannot move funds itself.

A Python MCP server exposes RustChain wallets, signed RTC transfers and bounties alongside BoTTube publishing and Beacon messaging; publishing needs credentials, and RTC is an internal reward/fee unit rather than an exchange-listed investment asset.

An agent-commerce service inspects x402 endpoints and signed offers or receipts, and publishes dated observations; basic checks are free and paid products use quoted crypto settlement, but observations do not guarantee payment settlement or delivery.

MCP tools create crypto payment links, tip jars and paid digital unlocks for a supplied destination wallet; basic tools need no account, while richer invoice management requires a Shieldz API key.

NodeFlare MCP gives agents EVM-chain RPC queries, wallet reports, logs and transaction simulation. Basic reads are keyless and rate-limited; heavier methods need a key or x402 wallet, which can automatically pay real USDC when a request requires payment.

Multichain MCP exposes balances and prices across Stacks, Celo and Base, with portfolio aggregation and unsigned transfer or token-deployment preparation on paid tiers. Users sign transactions externally; basic queries use public endpoints and advanced functions need a license.

Payfetch is a local MCP server and CLI that fetches paid x402 URLs under operator-defined spending and host policies. It needs a wallet signer, currently supports exact-scheme Base USDC only, and can spend real funds; Windows and other payment rails are unsupported.
