README

@cryptoapis-io/mcp-contracts

MCP server for Crypto APIs Contracts product. Get token details by contract address for EVM and Solana.

API Version: Compatible with Crypto APIs version 2024-12-12

Features

EVM contracts: Get token details by contract address (blockchain, network, contractAddress)
Solana contracts: Get token details by contract address (network, contractAddress)

Prerequisites

Installation

npm install @cryptoapis-io/mcp-contracts

Or install all Crypto APIs MCP servers: npm install @cryptoapis-io/mcp

Usage

# Run with API key
npx @cryptoapis-io/mcp-contracts --api-key YOUR_API_KEY

# Or use environment variable
export CRYPTOAPIS_API_KEY=YOUR_API_KEY
npx @cryptoapis-io/mcp-contracts

# HTTP transport
npx @cryptoapis-io/mcp-contracts --transport http --port 3000 --api-key YOUR_API_KEY

Claude Desktop

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS, %APPDATA%\Claude\claude_desktop_config.json on Windows):

{
  "mcpServers": {
    "cryptoapis-contracts": {
      "command": "npx",
      "args": ["-y", "@cryptoapis-io/mcp-contracts"],
      "env": {
        "CRYPTOAPIS_API_KEY": "your_api_key_here"
      }
    }
  }
}

Cursor

Add to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "cryptoapis-contracts": {
      "command": "npx",
      "args": ["-y", "@cryptoapis-io/mcp-contracts"],
      "env": {
        "CRYPTOAPIS_API_KEY": "your_api_key_here"
      }
    }
  }
}

MCP Inspector

npx @modelcontextprotocol/inspector npx @cryptoapis-io/mcp-contracts --api-key YOUR_API_KEY

n8n

Start the server in HTTP mode:

npx @cryptoapis-io/mcp-contracts --transport http --port 3000 --api-key YOUR_API_KEY

In your n8n workflow, add an AI Agent node
Under Tools, add an MCP Client Tool and set the URL to http://localhost:3000/mcp

All servers default to port 3000. Use --port to assign different ports when running multiple servers.

Available Tools

`evm_contract_data`

Get token details by contract address.

Action	Description
`get-token-details-by-contract-address`	Get token details (name, symbol, standard, decimals, totalSupply) by contract address

Supported Blockchains: ethereum, ethereum-classic, binance-smart-chain (mainnet, mordor, testnet, sepolia)

Contract token details are currently available for Ethereum, Ethereum Classic, and BSC only.

`solana_contract_data`

Get Solana token details by contract address.

Action	Description
`get-token-details-by-contract-address`	Get token details by contract address

Supported Networks: mainnet, devnet

CLI Arguments

Argument	Description	Default
`--api-key`	Crypto APIs API key	`CRYPTOAPIS_API_KEY` env var
`--transport`	Transport type: `stdio` or `http`	`stdio`
`--host`	HTTP host	`0.0.0.0`
`--port`	HTTP port	`3000`
`--path`	HTTP path	`/mcp`
`--stateless`	Enable stateless HTTP mode	`false`

HTTP API Key Modes

When using HTTP transport, the server supports two API key modes:

With --api-key: The key is used for all requests. x-api-key request headers are ignored.
Without --api-key: Each request must include an x-api-key header with a valid Crypto APIs key. This enables hosting a public server where each user provides their own key.

# Per-request key mode (multi-tenant)
npx @cryptoapis-io/mcp-contracts --transport http --port 3000
# Clients send x-api-key header with each request

Stdio transport always requires an API key at startup.
