Provides a three-layer payment firewall for AI agents, enabling identity verification, risk screening, and execution authorization with on-chain policy enforcement for secure and auditable transactions.
Agent-Q is an MCP server that separates execution surfaces from signing authority, enabling secure Sui signing flows where the signing device holds keys and policy while requesters submit bounded signing requests through a local host process.
Settlement rails for AI labor — USDC escrow on Base Mainnet, 1% protocol fee, designed for autonomous agents.
10 MCP tools covering the full escrow lifecycle:
* Quoting calldata for create-intent, submit-proof, release-funds (broadcast gated)
* Single-call x402 payment binding (replaces the 5-step x402 dance with one HMAC-signed POST)
* Server-side reputation from on-chain event scan
* Li
Enables AI agents to inspect the public NFH protocol corpus, verify census status, and prepare bounded Ethereum wallet intents for claims and non-custodial market actions while never signing or submitting transactions.
A Model Context Protocol server that enables Claude AI to interact with the Solana blockchain, allowing it to execute transactions, query accounts, manage wallets, get price predictions, trade tokens, and access various blockchain data sources.
Enables AI agents to interact with the Lido protocol for ETH staking, position management, and governance participation across Ethereum and L2 networks. It provides tools for querying balances, simulating transactions, and executing complex workflows like withdrawals and DAO voting through a safety-first interface.
A comprehensive MCP server providing unified access to over 144 tools for lending, trading, and staking across six major DeFi protocols on the Stacks Bitcoin Layer 2. It enables AI agents to perform complex blockchain operations and interact with the DeFi ecosystem using natural language commands.
