"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.

Enables static security audit of Solidity smart contracts by analyzing source code or deployed bytecode for vulnerabilities, providing risk scores and detailed findings.

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.

Universal x402 buyer agent — discover, pay for, and call any x402 paid API endpoint from Claude Desktop, Cursor, or Claude Code with automatic USDC payment via AgentCash.

MCP server for DeFi execution — lets AI agents swap, provide liquidity, lend, bridge, and run yield strategies across 22 chains in a single transaction. 7 tools for token discovery, portfolio analysis, quoting, and execution via the Haiku API.

Enables cross-chain swap execution across 12 venues and 17 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.

MCP server for the AKKA Finance DEX aggregator — swap quotes, routes, and execution across EVM chains.

Enables AI agents to perform native trading on True Markets by providing tools for price lookups, balance management, and secure trade execution with quote caching. It replaces fragile CLI-based workflows with structured JSON responses and persistent authentication for more reliable financial operations.

Pre-flight oracle for x402 endpoints — gives any MCP-aware agent (Claude Code, Cursor, Windsurf, Continue) tools to detect decoys, zombies, and price traps before paying. Wraps preflight, forensics, decoy-blacklist, and watch-subscription endpoints from x402station.io.

Enables LLMs to compile and verify Tolk smart contract code for the TON blockchain.

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.

Provides local access to Aztec documentation, examples, and source code via cloned repositories, with optional semantic search for enhanced querying.

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

Enables 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.

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.

Enables 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.

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.

An 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.
