Alchemy's official MCP Server that exposes Alchemy blockchain APIs to AI agents via the Model Context Protocol.
https://github.com/alchemyplatform/alchemy-mcp-serverYou're building an AI agent that needs blockchain data. You could spend days writing API wrappers, handling rate limits, and managing multichain complexities. Or you could be querying live blockchain data in the next 5 minutes.
Alchemy's official MCP server eliminates the integration overhead between AI agents and blockchain APIs. Instead of building custom connectors, your agents can directly query token prices, NFT ownership, transaction history, and wallet balances across multiple networks using natural language.
Building blockchain-aware AI applications typically means:
The Alchemy MCP server handles all of this. Your AI agents can ask questions like "What NFTs does this wallet own?" or "Show me the price history of ETH last month" and get structured responses immediately.
Instant Blockchain Queries: Eight pre-built methods covering the most common blockchain data needs - token prices, NFT ownership, transaction history, and wallet balances.
Multichain by Default: Query data across Ethereum, Base, Polygon, and other networks without managing different API endpoints or authentication schemes.
Zero Configuration: One API key, one config block, and you're querying live blockchain data. No database setup, no custom schemas, no API wrapper maintenance.
Production-Ready: Built by Alchemy, the same infrastructure powering major DeFi protocols and NFT marketplaces.
Instead of building custom blockchain integration:
// What you'd normally write
const response = await fetch(`https://eth-mainnet.g.alchemy.com/v2/${apiKey}`, {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
jsonrpc: '2.0',
method: 'alchemy_getTokensForOwner',
params: [address, 'erc20'],
id: 1
})
});
const data = await response.json();
// Plus error handling, rate limiting, response parsing...
Your AI agent simply asks:
"What tokens does wallet 0x1234...5678 hold on Ethereum and Base?"
The MCP server handles authentication, multichain queries, response formatting, and error cases automatically.
AI Trading Assistants: Agents that analyze wallet holdings, track token movements, and provide portfolio insights without you building custom blockchain data pipelines.
NFT Analytics Tools: Applications that need to understand collection ownership, track transfers, and analyze market activity across multiple chains.
DeFi Protocol Analysis: Agents that monitor protocol usage, track large transactions, and analyze user behavior patterns.
Compliance and Monitoring: Tools that track specific wallets, monitor large transfers, and generate reports on blockchain activity.
Add to your MCP configuration:
{
"mcpServers": {
"alchemy": {
"command": "npx",
"args": ["-y", "@alchemy/mcp-server"],
"env": {
"ALCHEMY_API_KEY": "YOUR_API_KEY"
}
}
}
}
Your agents immediately gain blockchain query capabilities. No additional setup, no custom code, no API management complexity.
The server exposes eight carefully chosen methods that cover 90% of blockchain data needs:
Each method is optimized for AI agent consumption, returning structured data that agents can immediately understand and act upon.
The MCP Inspector provides a visual debugging interface to test queries and understand response formats before deploying to production.
Blockchain data integration has been a bottleneck for AI application development. You either spend significant time building custom solutions or limit your agents to basic functionality.
This MCP server removes that constraint. Your development time shifts from integration work to building unique agent behaviors and user experiences.
