@wkalidev/multichain-mcp

The only MCP server that gives AI agents native access to Stacks, Celo, and Base — from a single npm package.

Connect Claude Desktop, Cursor, or any MCP-compatible AI to 3 blockchains in under 5 minutes.

Why this exists

Building an AI agent that interacts with Web3 today means writing separate integrations for every chain. This package ships a production-ready MCP server with 5 battle-tested tools across Stacks (Bitcoin L2), Celo, and Base — no RPC keys required to start.

Pricing

| Tier | Price | Tools | | |------|-------|-------|-| | Free | $0 | get_balance, get_prices | | | Pro | $9/mo | + get_portfolio, prepare_transfer | Lemon Squeezy → · GitHub Sponsors → | | Team | $29/mo | + deploy_token | Lemon Squeezy → · GitHub Sponsors → |

Tools included

ToolDescriptionTier
get_balanceNative + token balances for any walletFree
get_pricesLive prices + 24h change (STX, CELO, ETH, USDC, WBTC…)Free
get_portfolioAggregate view across all 3 chains in one callPro
prepare_transferBuild unsigned tx for native or ERC-20/SIP-010 transferPro
deploy_tokenPrepare unsigned ERC-20 deployment tx on Celo or BaseTeam

All write operations return unsigned transactions — your users always sign with their own wallet. Non-custodial by design.

Install

npm install @wkalidev/multichain-mcp

Claude Desktop setup

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "multichain": {
      "command": "npx",
      "args": ["-y", "@wkalidev/multichain-mcp"],
      "env": {
        "MULTICHAIN_LICENSE_KEY": "your-license-key"
      }
    }
  }
}

Omit the env block to run on the Free tier. Restart Claude Desktop after adding your key.

Cursor / Windsurf setup

Add to .cursor/mcp.json or .windsurf/mcp.json:

{
  "mcpServers": {
    "multichain": {
      "command": "npx",
      "args": ["-y", "@wkalidev/multichain-mcp"],
      "env": {
        "MULTICHAIN_LICENSE_KEY": "your-license-key"
      }
    }
  }
}

Usage examples

Check Stacks wallet
"What tokens does SP2C2YFP12AJZB4MABJBAJ55XECVS7E4PMMZ89YZR hold on Stacks?"
→ get_balance({ address: "SP2C2YFP...", chain: "stacks" })
Full multichain portfolio
"Show me my full portfolio across all chains"
→ get_portfolio({ addresses: { stacks: "SP...", celo: "0x...", base: "0x..." } })
Deploy a token
"Deploy a token called GreenDAO with symbol GRN, 1M supply on Base"
→ deploy_token({ chain: "base", name: "GreenDAO", symbol: "GRN", totalSupply: "1000000", ownerAddress: "0x..." })
Live prices
"What are the current prices of STX, CELO and ETH?"
→ get_prices({ symbols: ["STX", "CELO", "ETH"] })
