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

Enables AI agents to query live on-chain data from The Graph's decentralized network with built-in verification and computed risk insights for Uniswap V3 pools, such as swap counts, directional flow, and concentration signals.

Enables querying Base Network blockchain data including blocks, transactions, balances, and smart contracts on mainnet and testnet.

A Model Context Protocol server for creating, updating, and querying semantic relationships (cyberlinks) on Cosmos-based blockchains through integration with Cursor IDE and Claude Desktop.

A Model Context Protocol server that enables interaction with Service Nervous System (SNS) DAOs on the Internet Computer, allowing users to list proposals, view neurons, get system parameters, manage wallets, and vote on proposals.

Provides comprehensive access to the Ethereum Follow Protocol (EFP) API, enabling social graph queries, follower/following management, ENS resolution, and profile data retrieval for Ethereum addresses and ENS names.

Enables AI agents to interact with the AI Network blockchain by managing accounts, submitting transactions, and reading database values. It supports registering Hyper Agents and accessing a Layer 2 DAG-based shared agent memory system based on staking status.

Provides complete HTTP/JSON access to all 100+ Emercoin RPC endpoints with integrated formatting utilities. Enables blockchain operations, name system management, wallet functions, and mining operations through a comprehensive REST API interface.

Provides LLM access to Unicity gaming platform games through a payment-gated day pass system. Supports game discovery, access management, and payment processing via Nostr protocol and Unicity blockchain.

Rescues USDC, USDT and USDG from wallets with no gas. Agents check a wallet for stuck or frozen stablecoins, quote a send or a swap into the gas coin, collect the wallet signature and track the transfer. Base, Arbitrum, Ethereum, Polygon, Avalanche, BNB Chain, HyperEVM, Robinhood Chain, Solana and Tron.

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 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.

Lets AI agents check whether an EVM wallet address carries an EIP-7702 delegation across eight chains (Ethereum, Base, BNB Chain, Arbitrum, OP, Polygon, Gnosis, Unichain) and learn how to obtain a deeper paid report with delegate bytecode heuristics and risk levels. Read-only, never touching private keys or seed phrases.

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.

WaxSeal MCP gives AI agents cryptographic identity — verify any WaxSeal fingerprint, check Ed25519 signatures, and gate irreversible actions with human-signed approval tokens before execution. It connects Claude Desktop, Cursor, and Windsurf to the WaxSeal trust network so agents can prove who authorized an action and reject tampered credentials in under a second.

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.

Enables checking whether a crypto link is a phishing lookalike of a wallet, exchange or dapp by comparing it against official domains and flagging lookalike characters, typosquats, punycode and bait words, fully offline. An optional paid full check adds domain registration age, DNS, redirect tracing and a page scan for seed-phrase prompts and drainer code.

An MCP server that provides real-time web search to AI agents via a pay-per-search USDC microtransaction system.

Enables read-only verification of Unlock Protocol lock membership on-chain, checking whether a wallet holds a valid key for a lock on supported networks.

Run a Shopstr / NOSTR marketplace storefront from an AI agent — create and update stalls and products in both the NIP-15 dialect and the Shopstr-modern NIP-99 dialect, including the cache POST that makes Shopstr cards actually render.

Pre-trade safety for EVM, Solana and TRON: simulates a real buy and a real sell against live liquidity, so a honeypot shows as a sell that fails instead of a vendor score, and audits a wallet's standing approvals across the three chains. Python standard library only, no API key.

On-chain rug-pull & honeypot risk screen for ERC-20 tokens, providing a SAFE / CAUTION / HIGH-RISK verdict based on live public RPC reads.

A read-only MCP server that exposes BaseZap's tipping-agent tools to any MCP client, allowing users to fetch platform info, compute USDC tip quotes, build unsigned ERC-20 transfer calldata, and resolve Farcaster usernames to wallet addresses.

Mock identity-management MCP server for decentralized identity that allows minting DIDs, issuing signed Verifiable Credentials, and verifying them.

Enables an AI agent to check whether contracts are covered by ERC-7730 descriptors, preview how transactions and typed-data signatures would appear to a person, and simulate execution outcomes before signing, without holding keys or submitting transactions.

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.

A read-only Model Context Protocol server for the Thru blockchain alphanet, enabling account queries, transaction status, program events, name service resolution, faucet status, and network health via the official @thru/sdk.
