Pre-trade DeFi intelligence for AI agents. 20 paid x402 endpoints, USDC on Base.

MCP server that enables AI agents to search, describe, and fetch x402 endpoints on Base or Solana, with automatic USDC micropayments.

Provides AI agents with direct liteserver access to the TON blockchain for querying balances, account states, transactions, and contract get-methods without HTTP gateways.

Gives Claude a Solana wallet to send USDC, check balances, and manage blockchain transactions on Solana's devnet test network.

MCP server exposing fry.farm's x402 API as tools, enabling non-custodial blockchain interactions with pay-per-call endpoints on Algorand.

Exposes 8DX DEX aggregator REST endpoints as tools for AI agents, enabling token discovery, quotes, swaps, limit orders, and wallet execution via WalletConnect.

Enables Claude to interact with NEAR smart contracts: read state, call view methods, decode transactions, and explain contract interfaces.

A server that enables interaction with the Solana blockchain, providing access to over 40 Solana RPC methods including getting balances, transaction details, block information, and sending transactions.

A tool that enables users to interact with blockchain data to retrieve token total supply, chain IDs, and filtered RPC endpoints across different blockchain networks.

An MCP server that fetches on-chain blockchain data via the Ankr API, allowing LLMs to retrieve token balances for wallet addresses on specific networks.

Provides tools for AI assistants to interact with the Ethereum blockchain through standard JSON-RPC methods, enabling queries for account balances, gas prices, and smart contract code.

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.

Enables natural language queries and JSON-RPC calls to 69+ blockchain networks through Grove's free public endpoints. Supports Ethereum, Solana, Cosmos chains, and Layer 2 solutions without requiring authentication or API keys.

Facilitates interaction with Starknet blockchain via MCP by exposing various RPC methods, allowing users to query chain states, transaction details, and block information using natural language queries.

MCP server for cross-chain bridging, enabling AI agents to find routes, estimate costs, check risks, execute transfers, and track status across blockchains.

Enables to simulate EVM transactions (dry-run) to preview results, gas usage, and state changes before broadcasting on supported blockchains.

A server that interfaces with the Hedera Testnet Mirror Node API, converting its OpenAPI-defined endpoints into MCP-compatible tools that can be accessed over Server-Sent Events (SSE).

Provides AI agents with access to Gate.io's cryptocurrency exchange for market data, trading, and account management, plus DEX, news, and research tools via multiple MCP endpoints.
