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.

This MCP wraps Bitrefill public API to allow agents to search for products and shop using cryptocurrencies like Bitcoin, Ethereum, Solana, and many more.

Wallet-funded MCP client for six paid Utilia tools: Solana priority fees, transaction diagnosis and simulation, token-risk checks, PDF-to-Markdown, and audio normalization over x402. MIT-licensed and installable from npm.

Enables AI agents to detect and verify the language of texts, run bundle checks, and top up prepaid credits by paying per call in USDC on Solana, with no account, API key, or subscription needed. Payment is handled transparently via x402 challenges, prepaid credit tokens, or a funded payer wallet with sponsored gas.

A local-first MCP server for the WAX blockchain that enables AI hosts to query accounts, chain state, AtomicAssets, AtomicMarket, Hyperion history, and WAXP prices, as well as prepare unsigned transactions for wallet signing.

Enables AI-powered cryptocurrency trading and analytics across multiple exchanges and blockchains, with integrated Telegram bot and live trading capabilities.

MCP server for Chainlink Runtime Environment, enabling build, simulate, deploy, and manage CRE workflows from any MCP client.

Provides MCP tools to disassemble Kaspa scripts, estimate compute costs, explain txscript errors, and look up opcodes.

An MCP server that mints STAS, DSTAS, and BSV-21 tokens into a BSV Desktop wallet in seconds, enabling rapid token testing and development.

Enables AI agents to participate in tactical combat, matchmaking, and token trading within a Solana-based competitive arena, with Elo rankings, energy management, and benchmark testing against other agents.

RandomWeb3MCP is a random element generation service based on EVM block hash. The service provides various random element generation tools that can be used in games, finance, testing, and other fields.

AI-powered code generator for the Arbitrum ecosystem with 19 MCP tools. Generates Stylus smart contracts (Rust/WASM), SDK bridging code, full-stack dApps, and Orbit chain deployments using RAG-based retrieval over Arbitrum documentation.

Inspects and debugs Solana transactions, accounts, Anchor IDLs, errors, and PDAs from MCP-compatible clients.

Combines Midnight Network blockchain development tools with Next.js DevTools for building decentralized applications, supporting contract development, wallet management, and Next.js diagnostics.

A comprehensive Model Context Protocol server that transforms Cursor's AI assistant into a DeSo blockchain development expert, providing complete API coverage, debugging solutions, and code generation for DeSo applications.

Use the microservice of testraptor

A self-contained Rust MCP server for Polymarket that enables market discovery, exact order book queries, wallet analytics, realtime market state, and simulated fills, with optional gated trading.

A Model Context Protocol (MCP) server for Substrate blockchains, written in Rust and interfacing the subxt crate.

Enables AI agents to interact with Ethereum blockchain by querying ETH and ERC-20 token balances, fetching token prices from CoinGecko, and building/simulating Uniswap V3 swap transactions. Built in Rust with read-only mode by default for safety.

Checks live x402 routes across Base, Solana, and Algorand before agents spend. $0.003 USDC settles only for a valid live eligible route; normal typed misses are not settled. Free preview and validate tools. Seller payment is separate; the agent keeps its wallet. Optional signed route-binding receipts support buyer-side checks.
