Enables AI assistants to interact with blockchains securely, allowing users to maintain control over transaction signing.
Enables AI assistants to interact with blockchains securely, allowing users to maintain control over transaction signing.
An MCP server that lets AI assistants read blockchain data and prepare transactions — while the user keeps full custody of their keys and signs every transaction in their own wallet.
Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
| Tool | What it does |
|---|---|
| get-chains | List supported networks and their chain ids. |

Enables Claude AI to interact with the Solana blockchain through a standardized Model Context Protocol interface.
Enables AI agents to interact with the Solana blockchain and perform DeFi operations through a standardized interface.
Paid DeFi data for agents via x402 on Base: yields, APY moves, stablecoin pegs, token risk.
This repository contains a Model Context Protocol (MCP) server that provides Claude with access to Solana blockchain data via the Helius API. The server enables Claude to perform operations like…
Deploy and manage blockchain nodes across 70+ protocols, search docs, request testnet funds.
No-sign-up demo: recorded historical crypto wallet holdings, prices and CSV exports. Fixed examples.
