"Understanding Code Execution" matching MCP servers:

Gives Claude access to Alchemy blockchain APIs by loading all API specs at startup and providing two tools: search and execute. Enables querying NFTs, token balances, transactions, and more via natural language.

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.

WaxSeal MCP gives AI agents cryptographic identity — verify any WaxSeal fingerprint, check Ed25519 signatures, and gate irreversible actions with human-signed approval tokens before execution. It connects Claude Desktop, Cursor, and Windsurf to the WaxSeal trust network so agents can prove who authorized an action and reject tampered credentials in under a second.

Enables AI agents to create and post signal coins on the Base blockchain through tools for media uploads, transaction generation, and on-chain submission. It supports both fully headless automated execution and manual signing modes using the x402 payment protocol.

An MCP server for Klever blockchain smart contract development, providing contextual knowledge including code patterns, best practices, and runtime behavior.

MCP server that connects LLM agents to the Rustok self-custody crypto wallet via Gateway, enabling human-approved transaction execution and wallet management.

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.

MCP server enabling AI agents to perform cross-chain token swaps through NEAR's intent-based architecture using the Defuse Protocol, with token discovery, quote retrieval, swap execution, and status tracking.

DeFi execution on Base, Citrea, HyperEVM and Monad via Fibrous aggregation: swap quotes, swaps with optimal routing, native and ERC-20 transfers, cross-chain portfolio with USD valuations, and Aave V3 supply/borrow/repay/withdraw. Quotes, transaction status and Aave market data need no wallet, and transactional tools accept simulate=true for a preview that never broadcasts.

MCP server combining DEX Screener market data with Jupiter swap quotes and gated execution on Solana, offering read-only tools and an optional trading mode with safety caps.

MCP server that gives AI assistants access to Midnight blockchain—search contracts, analyze code, and explore documentation.

DeFi execution and agent-to-agent economy tools for AI agents — swaps, yield, transfers, policy enforcement, trust scoring, A2A jobs, and P\&L across Ethereum, Base, Arbitrum, and Polygon.

Enables AI agents to fetch and independently verify on-chain data such as account balances and contract code hashes using Merkle proofs and ECDSA signatures, with x402 payment integration.

Enables AI assistants to help developers integrate gasless transactions on the Aptos blockchain by providing access to documentation, code snippets, and transaction cost estimation. It facilitates interaction with the SmoothSend SDK and API through MCP-compatible tools like Cursor and Claude.

Exposes 8DX DEX aggregator REST endpoints as tools for AI agents, enabling token discovery, quotes, swaps, limit orders, and wallet execution via WalletConnect.

Karma economy for AI agents and humans. Submit good actions, get community attestations, earn on-chain reputation. Karma-weighted verification, slashing, Kleros disputes. 5 MCP tools: submit_action, attest_action, get_karma, get_action_detail, get_leaderboard.

MCP server for Helius — Solana blockchain data access for AI assistants, provided by Solana's fastest, most reliable infrastructure provider

Provides Ethereum blockchain data tools via Etherscan's API, enabling users to check balances, view transactions, track token transfers, fetch contract ABIs and code, monitor gas prices, and resolve ENS names.

Provides comprehensive access to Lyra Finance's Derive API with 31+ tools for trading options, perpetuals, and spot markets, including real-time market data, historical analytics, account management, and order execution.

Enables developers to integrate privacy-preserving identity verification from the Self protocol into their apps. Provides integration guides, code generation, blockchain configuration reading, and debugging assistance for age verification, airdrop eligibility, and humanity checks.
