Multichain MCP Server

Multichain MCP Server is an MCP server that provides AI applications with tools to interact directly with multiple blockchain networks and decentralized finance protocols. Developed by Oraichain Labs as part of a TypeScript monorepo, it enables autonomous agents and large language model clients to execute on-chain operations through a standardized Model Context Protocol interface. Developers and Web3 engineers use this server to equip their AI systems with wallet management, contract interaction, and asset movement capabilities across supported chains. By integrating directly with network RPC endpoints, such as Oraichain RPC, the server allows AI models to retrieve wallet addresses, check real-time token balances, transfer digital assets, and bridge tokens between distinct networks. It also supports smart contract deployment and contract invocation, handling transaction execution securely. Whether building automated trading agents, customer-facing DeFi assistants, or blockchain analytics bots, users can leverage this toolkit to bridge conversational AI models with distributed ledger infrastructure without building custom RPC wrappers for each network.

How to install and configure Multichain MCP Server

1. Ensure Node.js version 18 or higher and pnpm are installed. 2. Open your Claude Desktop configuration file located at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS, %APPDATA%\Claude\claude_desktop_config.json on Windows, or ~/.config/Claude/claude_desktop_config.json on Linux. 3. Add the server under your mcpServers object: json { "mcpServers": { "mcp-server": { "command": "npx", "args": ["-y", "@oraichain/mcp-server@0.0.21"], "env": { "RPC_URL": "https://rpc.orai.io" } } } } 4. Replace the RPC_URL variable if connecting to an alternate network endpoint. 5. Restart Claude Desktop to register the server and expose blockchain tools.

What you can do with Multichain MCP Server

• Checking wallet addresses and balances: Query account balances and inspect connected wallet addresses across supported networks using natural language prompts inside an LLM client. - Executing token transfers: Instruct AI agents to send cryptocurrency assets and tokens between blockchain accounts with structured transaction handling. - Interacting with smart contracts: Deploy new smart contracts or invoke existing contract functions directly through conversational commands given to an AI model. - Bridging tokens across chains: Automate asset transfers between different blockchain networks by executing cross-chain bridge transactions via MCP agent tools. - Integrating DeFi protocols: Connect autonomous trading bots and Web3 agents to decentralized finance protocols for liquidity queries and automated execution.
