Solscan MCP Server

A Model Context Protocol (MCP) server implementation for interacting with the Solscan Pro API. This server allows AI agents to fetch and analyze token, transaction, and DeFi activity data from the Solana blockchain.

Overview

This MCP server provides a bridge between AI agents and the Solscan Pro API service. It follows the best practices laid out by Anthropic for building MCP servers, allowing seamless integration with any MCP-compatible client.

Features

The server provides several essential tools for interacting with Solscan:

1. token_meta: Get token metadata

   • Fetch comprehensive token information
   • Get name, symbol, price, market cap, etc.

2. token_markets: Get token market data and liquidity pools

   • View market pairs and liquidity pools
   • Filter by program addresses
   • Sort and paginate results

3. token_holders: Get token holder distribution

   • View holder balances and distribution
   • Filter by amount ranges
   • Paginate through results

4. token_price: Get token price information

   • Historical price data
   • Filter by date range
   • Price trends and statistics

5. token_accounts: Get token holdings for a wallet

   • List token and NFT holdings
   • Filter zero balances
   • Paginate results

6. defi_activities: Get DeFi activities for a wallet

   • Filter by activity type and platform
   • Sort by time or other metrics
   • Comprehensive activity details

7. balance_change: Get balance change activities

   • Track token balance changes
   • Filter by token and amount
   • Remove spam transactions

8. account_transactions: Get wallet transactions

   • List wallet transactions
   • Paginate through transaction history
   • Configurable result limits

9. transaction_detail: Get transaction information

   • Detailed transaction data
   • Parsed instructions
   • Fee information

10. transaction_actions: Get transaction actions

• List token transfers
• View program interactions
• Decoded instruction data

Prerequisites

• Python 3.10+
• Solscan Pro API key (obtain from Solscan APIs)
• Docker if running the MCP server as a container (recommended)

Installation

Using uv (Recommended)

When using uv, no specific installation is needed. We use uvx to directly run solscan-mcp-server.

Using pip

Alternatively, install via pip:

pip install solscan-mcp-server

Configuration

You can configure the server using either environment variables or command-line arguments:

Option	Env Variable	CLI Argument	Default	Description
API Key	SOLSCAN_API_KEY	--api-key	Required	Your Solscan Pro API key
Transport	TRANSPORT	--transport	sse	Transport protocol (sse or stdio)
Host	HOST	--host	127.0.0.1	Host to bind to when using SSE transport
Port	PORT	--port	8050	Port to listen on when using SSE transport
Log Level	LOG_LEVEL	--verbose	INFO	Logging level (use -v or -vv for detail)

Running the Server

Using uvx (Recommended)

# Using environment variables:
SOLSCAN_API_KEY=your-key uvx solscan-mcp-server

# Using CLI arguments:
uvx solscan-mcp-server --api-key your-key

Using pip Installation

# Using environment variables:
SOLSCAN_API_KEY=your-key python -m solscan_mcp_server

# Using CLI arguments:
python -m solscan_mcp_server --api-key your-key

Using Docker

# Build the image
docker build -t solscan-mcp-server .

# Run with environment variables
docker run -e SOLSCAN_API_KEY=your-key solscan-mcp-server

Integration with MCP Clients

Claude Desktop Configuration

Using uvx (Recommended)

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "solscan": {
      "command": "uvx",
      "args": ["solscan-mcp-server"]
    }
  }
}

Using pip Installation

{
  "mcpServers": {
    "solscan": {
      "command": "python",
      "args": ["-m", "solscan_mcp_server"]
    }
  }
}

Zed Configuration

Add to your Zed settings.json:

"context_servers": {
  "solscan": {
    "command": {
      "path": "uvx",
      "args": ["solscan-mcp-server"]
    }
  }
}
