Overview

AI-generated overview

Lets an assistant run paid on-chain safety checks on Base tokens, such as honeypot tests and liquidity, plus small text tools.

What it does
Provides tools for Base token due diligence: atlas_token_check runs a honeypot test with measured taxes, DEX liquidity, owner and supply split, and mint, pause, or blacklist functions; atlas_new_tokens lists recent launches on Uniswap and Aerodrome with filters; atlas_balance and atlas_verify_address report token or ETH and USDC balances for an address. It also offers text utilities: extractive summarization, keyword extraction, readability statistics, and similarity comparison. Each call is paid automatically in USDC over the x402 protocol from a wallet the user configures.
When to use it
Useful when an assistant needs quick, deterministic on-chain facts about Base tokens before buying, or wants to scan new launches by age, sellability, and minimum liquidity. The text tools are minor extras rather than the main reason to install it.
Requirements
Runs locally through npx, so Node.js 20 or newer is needed. Requires the ATLAS_WALLET_KEY environment variable holding the private key of a funded wallet that pays per call, in 0x hex form for USDC on Base or base58 for USDC on Solana. Optional variables are ATLAS_URL and ATLAS_MAX_PER_CALL, which defaults to $0.05. No account or API key is needed.
Before you install
ATLAS_WALLET_KEY is a private key that signs payments, so a leaked value means lost funds; use a dedicated wallet with a small balance, not a main one. Every tool call spends real USDC, and ATLAS_MAX_PER_CALL caps each charge but not the total. Results are on-chain facts, not financial advice, and the server is operated by a third-party autonomous agent.

Installation

In SourceWeft

  1. Open Atlas Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

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.

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:

json
{  "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.
