23 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 graph

A set of MCP servers that provide AI agents with safe, composable access to web3 market data and trading, featuring read-only intelligence and execution modes with SIM/PAPER/LIVE safeguards.

MCP server for interacting with Bitcoin Agents on Stacks blockchain. Bitcoin Agents are Tamagotchi-style AI companions that live on-chain.

MCP server that prepares Proof of Invention (POI) transaction requests for submission

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.

9 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 attestation

Universal MCP server for discovery, chat, registration, credits, and workflow automation across the HOL Registry Broker ecosystem.

MCP server for Web3 AI agents enabling autonomous smart contract engineering on Robinhood EVM and Solana, with Cloudflare One portals for efficient token usage and edge execution.

Enables AI agents to inspect a shared canvas and paint pixels by paying in USDC via x402, with configurable spending limits and a dry-run mode.

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.

MCP server for Pi Network that enables AI agents to query Pi chain data (balances, transactions) and verify user tokens, with optional payment sending that is off by default.

Enables users to compare current Aerodrome veNFT voting positions, bounded claimable rewards, and selected pools' voting evidence on Base against a saved local baseline, with retryable, atomically stored change reports. All tools are read-only on chain, requiring no keys, signing, or transactions.

A server that enables interaction with the Solana blockchain, providing access to over 40 Solana RPC methods including getting balances, transaction details, block information, and sending transactions.

Pay x402 APIs in USDG on Robinhood Chain, borrow from and repay a Priors credit line, and read any ERC-8004 agent's repayment record and score, from the agent's own wallet (npx -y @priors/mcp).

Exposes fourteen read-only tools over the HEY Research public API, letting assistants look up Robinhood Chain projects, builders, shipped work, relationships and market context, with each answer tagged FACT, DERIVED or UNKNOWN and unmeasured fields omitted rather than zeroed. Runs over stdio or hosted Streamable HTTP, and gives no trade instructions.

Enables AI agents to create and manage contract-guarded USDC wallets on Base with enforceable per-payment, daily, and monthly caps, vendor allowlists, escalation thresholds, and freeze controls. It provides read-only policy checks plus unsigned transaction proposals for payments, funding, vendor management, wallet creation, and module deployment without holding keys or broadcasting.

MCP 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.

Enables autonomous agents to discover and call 35 pay-per-request microservices — pre-execution security guardrails, smart-contract auditing, Solana token and MEV risk oracles, web research, code sandboxes, and frontier AI models — settling each call atomically via Bitcoin Lightning L402, Solana x402, or Base MPP with no API keys, accounts, or subscriptions. It also offers a zero-token demo mode and drop-in integrations for Claude Desktop, Cursor, ElizaOS, LangChain, and CrewAI.
