# Alchemy MCP Server
A Model Context Protocol (MCP) server that enables AI agents to interact with Alchemy's blockchain APIs in a structured way. This allows agents to query blockchain data directly without writing any code.

## General Usage
This MCP server creates a bridge between AI agents and Alchemy's blockchain APIs, allowing agents to:
- Query token prices and price history (including flexible time frame queries)
- Get NFT ownership information and contract data
- View transaction history across multiple networks
- Check token balances across multiple blockchain networks
- Retrieve detailed asset transfers with filtering
- Send transactions via Smart Contract Accounts (**requires configured wallet agent server**)
- Execute token swaps via DEX protocols (**requires configured wallet agent server**)
- And more!
### Quick Setup
To quickly set up the MCP server, use the following configuration in your MCP config file (typically in Claude Desktop or Cursor settings):
```json
{
"mcpServers": {
"alchemy": {
"command": "npx",
"args": [
"-y",
"@alchemy/mcp-server"
],
"env": {
"ALCHEMY_API_KEY": "YOUR_API_KEY"
}
}
}
}
```
This configuration allows you to use the server without manually cloning the repository.
### Environment Variables
The MCP server requires the following environment variable:
- `ALCHEMY_API_KEY` - Your Alchemy API key (required for all blockchain data queries)
**For transaction and swap functionality**, you must also configure:
- `AGENT_WALLET_SERVER` - URL of a configured wallet agent server that handles Smart Contract Account operations
⚠️ **Important**: The `sendTransaction` and `swap` methods will not function without a properly configured wallet agent server. These methods require external wallet infrastructure to handle signing and broadcasting transactions.
## Available Methods
You can prompt your AI agent to use the following methods:
### Token Price Methods
1. **fetchTokenPriceBySymbol**
- Gets current price data for tokens by symbol
- Example: "What's the current price of ETH and BTC?"
2. **fetchTokenPriceByAddress**
- Gets current price data for tokens by contract address
- Example: "What's the price of the token at address 0x1234...5678 on Ethereum mainnet?"
3. **fetchTokenPriceHistoryBySymbol**
- Gets historical price data for tokens with specific date ranges
- Example: "Show me BTC price history from Jan 1 to Feb 1, 2023, with daily intervals"
4. **fetchTokenPriceHistoryByTimeFrame**
- Gets historical price data using flexible time frames or natural language
- Example: "Show me ETH price for the last week" or "Get BTC price for the past 30 days"
### Multichain Token Methods
5. **fetchTokensOwnedByMultichainAddresses**
- Gets token balances for addresses across multiple networks
- Example: "What tokens does 0xabc...123 hold on Ethereum and Base?"
### Transaction History Methods
6. **fetchAddressTransactionHistory**
- Gets transaction history for addresses across multiple networks
- Example: "Show recent transactions for wallet 0xdef...456 on Ethereum"
7. **fetchTransfers**
- Gets detailed asset transfer data with advanced filtering options
- Example: "Show me all ERC-20 transfers to or from 0xghi...789"
### NFT Methods
8. **fetchNftsOwnedByMultichainAddresses**
- Gets all NFTs owned by addresses with spam filtering
- Example: "What NFTs does 0xjkl...012 own?"
9. **fetchNftContractDataByMultichainAddress**
- Gets NFT contract data for addresses
- Example: "What NFT collections does 0xmno...345 have tokens from?"
### Transaction Methods
10. **sendTransaction**
- Sends transactions via Smart Contract Accounts
- **⚠️ Important**: Requires a configured wallet agent server with `AGENT_WALLET_SERVER` environment variable
- Example: "Send 0.1 ETH to 0xpqr...678"
### Swap Methods
11. **swap**
- Executes token swaps via DEX protocols (Uniswap)
- **⚠️ Important**: Requires a configured wallet agent server with `AGENT_WALLET_SERVER` environment variable
- Example: "Swap 100 USDC for ETH"
