"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 agents to compute exact Uniswap v3 Q64.96 tick math, quotes, and liquidity fees, simulate MEV sandwich vulnerability, model multi-hop flashloan arbitrage profits, and project Base L2 blob gas costs. Tools are metered per call in USDC via an x402 HTTP 402 challenge settled on Base L2, so an agent can verify net profitability before executing a trade.

Enables non-custodial generation of unsigned transaction payloads and official quote aggregations across Hyperliquid, Jupiter v6, LI.FI, CoW Protocol, Polymarket, and 0x v2. Supports transparent integrator fee attribution while leaving signing and broadcasting to the client wallet.

CLI and local stdio MCP payment runtime for AI agents on macOS Apple Silicon. Supports x402 offer inspection and payment preparation, with signing and execution requiring foreground owner approval.

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.

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.

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.

Enables paying for Ordinal marketplace calls from your own wallet in Claude Code or Codex, with local signing and gasless settlements.

Enables any existing API to become a pay-per-call service for agents by issuing HTTP 402 payment requests and settling USDC payments via CDP, while exposing MCP tools that charge per call and support Bazaar discovery.

An in-memory security MCP server for AI agents and coding copilots that prevents sensitive tool parameters and API keys from leaking into LLM context windows. Isolates execution arguments in local RAM using ephemeral cryptographic commitments and deterministic memory zeroization.

Trade, analyze, and automate Polymarket prediction markets via AI. 34 tools for direct trading, smart money flow, copy trading, backtest, and portfolio management.

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

Enables agents to run pre-signature security checks: identifying who can replace a Solana program's code or control an EVM contract's upgrades, surfacing dependency advisories for lockfiles, scanning public repos before release, and setting 30-day signed-webhook alerts on changes. Calls are paid per use in USDC over x402 from a wallet with per-call caps and a session budget.

Enables safe, local simulation of guarded block producer maintenance workflows, with tools for status inspection, plan generation, and approval/execution testing across three authority modes.
