"An overview or definition of a code interpreter" matching MCP servers:

Cross-chain cryptocurrency swaps via Chainflip. Get quotes, execute swaps, and track progress. No API key required to get started.

MCP server that prepares Proof of Invention (POI) transaction requests for submission

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 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.

Use the microservice of testraptor

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.

An MCP server that provides authorization middleware for AI agents using private data, enabling consent management on Aleo and local private inference with persistent policy storage.

An AI-driven platform for analyzing Polymarket prediction markets using on-chain data, offering smart money tracking, sentiment analysis, and arbitrage detection via natural language queries.

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

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

Provides tools and prompts for Bitcoin SV development, enabling code search, BRC lookup, and function definition search within locally cloned BSV repositories.

Provides a persistent memory layer for Stellar and Soroban projects, scanning repositories to create a knowledge graph of contracts, storage, and on-chain state. Exposes this memory to AI agents via MCP, enabling project overview, search, and context recovery.

MCP server for multi-party USDC settlement with validator consensus, enabling submission and tracking of settlements through a network of validators that vote to approve or reject transactions.

Enables read-only, keyless queries of timestamped, definition-backed data about AI agent payments and activity on Base, including rankings, agent records, detections, metric histories, and evidence-pack pricing, from MCP clients or the terminal.

Ag402 is the payment layer for Coinbase's x402 protocol. Wrap any API or MCP server with a paywall in one command (ag402 serve), or let your AI agent auto-pay for paid APIs (ag402 run). Zero code changes for both buyers and sellers. Solana USDC, ~0.5s settlement, non-custodial, 648+ tests, MIT licensed. Works with Claude Code, Cursor, OpenClaw, LangChain, AutoGen, CrewAI out of the box.

Exposes 8 read-only Trust Vault tools over MCP (Streamable HTTP) for querying protocol overview, tokens, market rates, orders, platform stats, fees, and currencies. Enables on-chain reads and static config without wallet or signing.

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.

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.

MCP server for RugGuard, enabling AI agents to perform pre-trade rug checks on tokens, with paid tools for token scanning and pre-trade verification, and a free metrics resource.

An MCP server that gives autonomous coding agents deterministic, schema-validated tools for EVM smart contract development — security scanning, gas profiling, compiler diagnostics, and transaction simulation.
