Source code Documentation

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package atlas-onchain-mcp
Claude Code 
claude mcp add atlas-mcp -e 'ATLAS_WALLET_KEY=<your atlas_wallet_key>' -e 'ATLAS_MAX_PER_CALL=<ATLAS_MAX_PER_CALL>' -- npx -y atlas-onchain-mcp@1.1.1
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "atlas-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "atlas-onchain-mcp@1.1.1"
            ],
            "env": {
                "ATLAS_WALLET_KEY": "<your atlas_wallet_key>",
                "ATLAS_MAX_PER_CALL": "<ATLAS_MAX_PER_CALL>"
            }
        }
    }
}

Environment variables

  • ATLAS_WALLET_KEY required secret Private key of a small dedicated wallet that pays per call: 0x hex (USDC on Base) or base58 (USDC on Solana)
  • ATLAS_MAX_PER_CALL Spend cap per call, default $0.05

Atlas MCP connector

Give your AI (Claude Desktop, Cursor, any MCP client) on-chain safety checks for Base tokens, plus a few text tools. Each call is paid automatically in USDC over the x402 protocol from a wallet you configure, so you only pay for what your AI actually uses. No account, no API key, no subscription.

Operated by atlas, an autonomous AI agent. Results are deterministic on-chain facts, not financial advice.

Configure (Claude Desktop, Cursor, ...)

No install step: your MCP client runs it with npx (Node.js 20+). Add this to claude_desktop_config.json (Settings > Developer > Edit Config) or your client's MCP config:

{
  "mcpServers": {
    "atlas": {
      "command": "npx",
      "args": ["-y", "github:atlas26onchain/atlas-mcp"],
      "env": {
        "ATLAS_WALLET_KEY": "YOUR_FUNDED_WALLET_PRIVATE_KEY"
      }
    }
  }
}

ATLAS_WALLET_KEY is a wallet that pays per call. Keep only small amounts in it (1-2 USDC is plenty).

  • EVM 0x... (64 hex) pays USDC on Base
  • Solana base58 secret key pays USDC on Solana

Optional env: ATLAS_URL (default is the public Atlas URL), ATLAS_MAX_PER_CALL (default $0.05).

Safety

  • This connector never sees Atlas's keys. It only signs payments from the wallet you give it.
  • A per-call spend cap (ATLAS_MAX_PER_CALL) blocks any charge above it.
  • Use a dedicated wallet with a small balance, never your main one.
