"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.

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.

Cross-chain bridge aggregator MCP server for AI agents. Compares routes across LI.FI, deBridge, Relay, Across and Squid to find the best rate. Use when an agent needs to bridge or swap tokens between EVM chains, Solana, or Cosmos. The aggregator of aggregators.

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.

Provides access to 70 paid APIs as MCP tools with per-call and session budgets, paying via x402/USDC on Base without requiring an account or login. Includes a built-in allowlist of hosts and safe defaults to prevent unintended payments.

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

Enables an AI agent to search a curator-signed catalog of smart contracts, build transaction plans with per-call trust tiers, and simulate them before a human reviews and signs locally with their own wallet. The server never holds a private key, refusing only calls whose deployed code no longer matches the signed codehash.

MCP server for witnessd, enabling agents to create tamper-evident, signed, and Merkle-anchored certificates of any public URL or API response at a moment in time.

MCP server for a pre-interaction risk check on any EVM contract/token, enabling agents to verify contracts before approving, swapping, or trusting an address.

A read-only MCP server for AI agents to access Nostr profiles, notes, search, and relay lists through user-chosen relays, without requiring an account or keys.

Enables tamper-evident anchoring of file, text, or JSON hashes to the BSV blockchain via MCP tools, with verification and lookup capabilities.

Enables AI agents to generate and persist a self-sovereign did:key identity, sign claims about their actions as Ed25519 attestations, verify those attestations offline without any registry or network access, and compute an auditable reputation score from a ledger of events. All four operations are exposed as MCP tools so an agent can manage its own identity and prove its history during a session.

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.

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.

Enables AI agents to read and bid on a paid message slot on Solana, with enforced spend limits, dry-run proposals, and an append-only audit log for every write.

MCP server for Pi Network that enables AI agents to query Pi chain data (balances, transactions) and verify user tokens, with optional payment sending that is off by default.

An MCP server that enables cross-chain token transfers via the Stargate protocol.

DexPaprika MCP server allows LLMs to access real-time and historical data on tokens, DEX trading activity, and liquidity across multiple blockchains. It enables natural language queries for exploring market trends, token performance, and DeFi analytics through a standardized interface.

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.

MCP server for OrcaTrace, a pay-per-call Polymarket intelligence feed for AI agents. It provides tools to track smart money, whale entries with calibration, market repricings, and digests across 42K prediction markets, with payments settled via x402 on Base.
