Gives Claude a Solana wallet to send USDC, check balances, and manage blockchain transactions on Solana's devnet test network.

A server that provides simple RPC endpoints for common Solana blockchain operations, allowing users to check balances, get account information, and transfer SOL between accounts.

A toolkit that integrates with the Sui blockchain, allowing Claude to request test tokens through a testnet faucet tool when users provide their wallet addresses.

Provides AI agents with knowledge and code generation tools for building BSV blockchain applications using @bsv/simple.

Resolves AR-IDs, manifest hashes, and provenance trees from any MCP-compatible AI client via the AnchorRegistry API.

Blockchain AI - MCP server providing AI-powered tools and automation by MEOK AI Labs

Cross-chain cryptocurrency swaps via Chainflip. Get quotes, execute swaps, and track progress. No API key required to get started.

A Model-Context-Protocol server enabling users to perform basic operations on Solana and Ethereum blockchains through simple RPC endpoints.

Enables AI agents to interact with the o2 Exchange on the Fuel Network to perform on-chain trading, manage accounts, and access real-time market data. It provides tools for executing various order types and calculating over 16 technical indicators for comprehensive market analysis.

MCP server that builds unsigned Paraswap token swap transactions for self-custody wallets, holding no keys and signing nothing. It returns raw transaction data for a human to review and approve before execution.

Enables cross-chain swap execution across 12 venues and 16 chains, including native Bitcoin as source or destination, with tools for quoting, execution, status, and health checks. No signup, API key, or protocol fee required.

Cross-chain bridge aggregator MCP server for AI agents. Compares routes across LI.FI, deBridge, Relay, Across and Squid to find the best rate. Use when an agent needs to bridge or swap tokens between EVM chains, Solana, or Cosmos. The aggregator of aggregators.

A read-only MCP server for safely exploring Nostr, enabling agents to resolve identifiers, fetch profiles and events, query notes, and inspect relay metadata. It does not accept private keys or publish events.

Enables AI agents to interact with a Liquid network wallet, including balance checks, transaction history, and sending L-BTC or Liquid assets. Backed by an in-process LWK wallet, requiring only a mnemonic, with both stdio and HTTP support.

MCP server for the Elfa API, providing crypto social intelligence from X and Telegram, including trending, mentions, narratives, and market chat. It also supports Auto, a condition engine for automated monitoring and actions.

A self-hosted decision engine that sits between an AI agent and blockchain execution. Agents submit a proposed action, Guardian returns an explainable ALLOW / WARN / BLOCK before anything gets signed or broadcast.

Enables AI agents to build, test, deploy, invoke, and inspect Soroban smart contracts on the Stellar network through structured MCP tools and resources.

Connects AI agents and developers to structured blockchain data across multiple networks through Nodit's Web3 infrastructure, enabling easy querying, analysis and interaction with blockchain ecosystems without specialized development expertise.

Blockchain JSON-RPC on 23 EVM chains for AI agents — Ethereum, Base, Arbitrum, plus young chains like Robinhood Chain, Plasma and Ink. Free reads with no key; heavy methods (eth_getLogs, trace, debug) via a free API key or x402 USDC pay-per-call.

Search 14,000+ x402-enabled HTTP APIs by keyword. Agents pay $0.01 USDC per search via x402 micropayments on Base mainnet — no API keys or accounts required.
