@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
| Tool | Description | Tier |
|---|
get_balance | Native + token balances for any wallet | Free |
get_prices | Live prices + 24h change (STX, CELO, ETH, USDC, WBTC…) | Free |
get_portfolio | Aggregate view across all 3 chains in one call | Pro |
prepare_transfer | Build unsigned tx for native or ERC-20/SIP-010 transfer | Pro |
deploy_token | Prepare unsigned ERC-20 deployment tx on Celo or Base | Team |
All write operations return unsigned transactions — your users always sign with their own wallet. Non-custodial by design.
Install
npm install @wkalidev/multichain-mcp

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..." })
