"A simple test or quiz" matching MCP servers:

mcp-server-test

A simple MCP server for interacting with Marinade Finance on Solana, providing real-time updates and secure transactions.

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 simple MCP server implementation that provides AI models with basic Solana RPC methods and helpful development prompts.

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.

Pay-per-task AI agent for writing, research, code, DeFi & blockchain. Pay in USDC on Base or Solana. Supports A2A, MCP, x402 and Agentmail protocols.

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 inspect the public NFH protocol corpus, verify census status, and prepare bounded Ethereum wallet intents for claims and non-custodial market actions while never signing or submitting transactions.

Enables AI agents to make pay-as-you-go AI inference requests through x402 with automatic Solana USDC payments, no API keys or registration, while enforcing configurable spending limits.

Quick-scan a smart contract for rug, honeypot, or centralization risk before sending funds. It combines verified source, live on-chain state, and heuristic Solidity analysis to return a SAFE/CAUTION/HIGH-RISK verdict.

Decodes Ethereum calldata and returns a safety verdict with plain-English explanations of what the transaction does, flagging dangerous actions like unlimited approvals or gasless permits.

Live liquidity-pool scores for Solana + EVM: Enter/Hold/Exit verdicts and a composite 0-100 Wealthville Score, backed by a public, immutable track record that includes misses. Read-only, free, no key required. Data product, not financial advice.

Provides access to live swap quotes and routing on the Base network via the o1.exchange DEX aggregator. Read-only and safe by default, it returns routing data and unsigned calldata for you to sign in your own wallet.

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.

Zero-knowledge proof generation MCP server. AI agents can prove identity claims (Coinbase KYC, Country, Google OIDC, Google Workspace, Microsoft 365) without revealing personal data. Runs in AWS Nitro Enclave TEE with x402 USDC payments.

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.

A keyless MCP server that builds unsigned Uniswap v3 liquidity-position transactions and optionally simulates them via eth_call; it never holds keys or signs.

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