About atlas-mcp

atlas-mcp provides Base token safety checks and text utilities for MCP clients. Calls are paid automatically in USDC through x402 from a configured wallet, without an account or API key.

Key features

  1. 01Token honeypot and contract checks
  2. 02New Base token launch listings
  3. 03ERC-20 and address balance checks
  4. 04Text summary and keyword extraction
  5. 05Text readability and similarity tools
  6. 06Per-call USDC payments via x402

Use cases

  1. 01Check a Base token before a purchase
  2. 02Find recent sellable launches with liquidity filters
  3. 03Inspect an address or token balance on Base
  4. 04Summarize or compare text

MCP support

It exposes token, address, and text tools to MCP clients. Each call is paid in USDC via x402 using a wallet configured by the client operator.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

Environment variables to set
ATLAS_WALLET_KEYSecretPrivate key of a small dedicated wallet that pays per call: 0x hex (USDC on Base) or base58 (USDC on Solana)
ATLAS_MAX_PER_CALLSpend cap per call, default $0.05

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Details

From the project README

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.

Tools

ToolWhat it doesPrice
atlas_token_checkIs this Base token safe to buy? Honeypot test (simulated buy, transfer, sell) with measured taxes, DEX liquidity in USD, owner/supply split, proxy, mint/pause/blacklist functions0.03 USDC
atlas_new_tokensNew token launches on Base (Uniswap v2/v3, Aerodrome), each already checked: filter by time, sellable only, minimum liquidity0.02 USDC
atlas_balanceBalance of any ERC-20 token for a wallet on Base0.01 USDC
atlas_verify_addressContract or wallet, ETH and USDC balance of a Base address0.01 USDC
atlas_summarizeExtractive summary of a text0.01 USDC
atlas_keywordsTop keywords and phrases0.01 USDC

atlas_similaritySimilarity of two texts0.01 USDC

Example prompts: "Check 0x... on Base before I buy it." / "Show me tokens launched on Base in the last 2 hours that can be sold and have at least $10k liquidity."

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.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
