- AlicenseCqualityCmaintenance23 tools for AI agents working with Nostr Open source. No API key. No account. NIP-46 remote signing Publish notes, reply, react, repost Encrypted DMs (NIP-04 + NIP-44) Fetch events, profiles, social graph23141MIT
- Alicense-qualityDmaintenanceMCP server providing real-time crypto prices (Chainlink + Binance), Polymarket prediction market data, deep web research, and JS-rendered web scraping. All services available via x402 Solana micropayments.MIT
- Alicense-qualityDmaintenancePay-per-task AI agent for writing, research, code, DeFi & blockchain. Pay in USDC on Base or Solana. Supports A2A, MCP, x402 and Agentmail protocols.4MIT
- Flicense-qualityDmaintenanceMCP server for Chainlink Runtime Environment, enabling build, simulate, deploy, and manage CRE workflows from any MCP client.
- Flicense-qualityDmaintenanceA 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.4
- FlicenseAqualityCmaintenance9 tools, Lightning-gated. Pay per call. For agents that need verifiable signed actions with an audit trail. Nostr event signing via daemon Publish events to relays Create Lightning invoices Action receipts — signed proof of agent actions Identity attestation9
- Alicense-qualityCmaintenanceProvides 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.484MIT
- AlicenseAqualityBmaintenanceAn MCP server that gives autonomous coding agents deterministic, schema-validated tools for EVM smart contract development — security scanning, gas profiling, compiler diagnostics, and transaction simulation.91MIT
- AlicenseAqualityAmaintenanceMCP server for Project CPU, a blockchain game on EVM. It lets an AI agent play on your behalf: read the world map, reveal cells, build and mine, craft, move resources, trade at marketplaces, and cash out to on-chain $CPU.49299MIT
- AlicenseAqualityDmaintenanceEnables AI coding agents to scan smart contracts and code for vulnerabilities, check against 12 famous-hack patterns, and return public security receipts directly in the IDE.414MIT
- AlicenseAqualityDmaintenanceEnables searching over 20,000+ smart contract audit findings from Solodit, with filters for severity, firm, tags, and more. Designed for use with AI coding agents like Claude Code and Codex CLI.466155MIT
- AlicenseAqualityCmaintenanceUnifies 11 protocol specification repositories (EIPs, BIPs, CIPs, etc.) and canonical contract addresses across 10 chains into a local FTS5 index, enabling coding agents to retrieve exact spec text and contract addresses via natural language queries.421MIT
- AlicenseAqualityCmaintenanceEnables AI agents to build, test, deploy, invoke, and inspect Soroban smart contracts on the Stellar network through structured MCP tools and resources.6MIT
- AlicenseAqualityDmaintenanceAn MCP server that lets your AI coding agent (Claude Code, OpenClaw, Codex, Cursor, etc.) discover and pay on-chain agents registered on ERC-8004, using Coinbase's official x402 protocol. No smart account. No bundler. No relay. Just your EOA, an HTTPS request, and an automatic 402 → sign → retry flow.35MIT
- AlicenseAqualityDmaintenanceGives AI agents a smart-contract wallet on Base (USDC) with 10 stdio tools: create wallets, send USDC payments, pay x402-protected HTTP resources, and run ERC-8183 escrow Jobs for A2A service delivery.1014MIT
- AlicenseAqualityBmaintenanceMCP server that enables AI agents to make autonomous Bitcoin Lightning Network payments using the L402 protocol. Agents can pay for API access, purchase resources, and complete transactions without human intervention — invoice comes in, sats go out, done.179MIT
