@cryptoapis-io/mcp-address-history
MCP server for Crypto APIs Address History product. Query full blockchain address transaction history for synced addresses.
API Version: Compatible with Crypto APIs version 2024-12-12
Features
- Query complete EVM address history (Ethereum, Ethereum Classic, BSC, Polygon, Tron)
- Query complete UTXO address history (Bitcoin, Bitcoin Cash, Litecoin, Dogecoin, Dash, Zcash)
- Manage address sync (activate, sync, delete, list)
- Query by timestamp range
- Cursor-based pagination for large result sets
Prerequisites
To use this MCP server, you need:
- Register at Crypto APIs
- Generate an API key from your dashboard
Installation
npm install @cryptoapis-io/mcp-address-history
Or install all Crypto APIs MCP servers: npm install @cryptoapis-io/mcp
Usage
# Run with API key
npx @cryptoapis-io/mcp-address-history --api-key YOUR_API_KEY
# Or use environment variable
export CRYPTOAPIS_API_KEY=YOUR_API_KEY
npx @cryptoapis-io/mcp-address-history
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-address-history": {
"command": "npx",
"args": ["-y", "@cryptoapis-io/mcp-address-history"],
"env": {
"CRYPTOAPIS_API_KEY": "your_api_key_here"
}
}
}
}
Cursor
Add to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):
{
"mcpServers": {
"cryptoapis-address-history": {
"command": "npx",
"args": ["-y", "@cryptoapis-io/mcp-address-history"],
"env": {
"CRYPTOAPIS_API_KEY": "your_api_key_here"
}
}
}
}
MCP Inspector
npx @modelcontextprotocol/inspector npx @cryptoapis-io/mcp-address-history --api-key YOUR_API_KEY
n8n
- Start the server in HTTP mode:
npx @cryptoapis-io/mcp-address-history --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
--portto assign different ports when running multiple servers.
Available Tools
manage_address
Manage synced addresses for historical data access. Supports all EVM and UTXO blockchains.
Actions:
| Action | Description |
|---|---|
sync | Sync a new address for historical data |
activate | Activate a previously synced address |
delete | Delete a synced address |
list | List all synced addresses |
evm_address_history
Query EVM address full history (requires synced address).
Actions:
| Action | Description |
|---|---|
get-statistics | Get address statistics |
list-transactions | List all transactions |
list-transactions-by-timestamp | List transactions from a timestamp |
list-token-transfers | List token transfers |
list-internal-transactions | List internal transactions |
list-tokens | List tokens held by address |
Supported Blockchains: ethereum, ethereum-classic, binance-smart-chain, polygon, tron
Note:
get-statisticsandlist-transactions-by-timestamponly support Ethereum and Ethereum Classic. Other actions support all five blockchains.
utxo_address_history
Query UTXO address full history (requires synced address).
Actions:
| Action | Description | Pagination |
|---|---|---|
get-statistics | Get address statistics | - |
list-transactions | List all transactions | cursor |
list-transactions-by-timestamp | List transactions from timestamp | cursor |
list-unspent-outputs | List unspent outputs (UTXOs) | offset |
Supported Blockchains: bitcoin, bitcoin-cash, litecoin, dogecoin, dash, zcash
Pagination
Most endpoints use cursor-based pagination:
// Response
{
"items": [...],
"limit": 10,
"hasMore": true,
"nextStartingAfter": "abc123"
}
Use nextStartingAfter value as startingAfter parameter in the next request.
Exception: list-unspent-outputs uses offset pagination:
// Response
{
"items": [...],
"limit": 10,
"offset": 0,
"total": 150
}
Configuration
For stdio transport, provide the API key at startup via CLI argument or environment variable. For HTTP transport, it can also be provided per-request via x-api-key header (see HTTP API Key Modes).
-
Command-line argument (recommended):
npx @cryptoapis-io/mcp-address-history --api-key {your_api_key} -
Environment variable:
export CRYPTOAPIS_API_KEY={your_api_key}
CLI Arguments
| Argument | Description |
|---|---|
--api-key | Crypto APIs API key |
--transport | Transport type: stdio (default) or http |
--host | HTTP host (default: 0.0.0.0) |
--port | HTTP port (default: 3000) |
--path | HTTP path (default: /mcp) |
--stateless | Enable stateless mode for HTTP |
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-keyrequest headers are ignored. - Without
--api-key: Each request must include anx-api-keyheader 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-address-history --transport http --port 3000
# Clients send x-api-key header with each request
Stdio transport always requires an API key at startup.
Important: API Key Required
Warning: Making requests without a valid API key — or with an incorrect one — may result in your IP being banned from the Crypto APIs ecosystem. Always ensure a valid API key is configured before starting any server.
Remote MCP Server
Crypto APIs provides an official remote MCP server with all tools available via HTTP Streamable transport at https://ai.cryptoapis.io/mcp. Pass your API key via the x-api-key header — no installation required.
