Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account wkalidev for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A local MCP server that gives an AI assistant read access to Stacks, Celo and Base wallets and prices, plus unsigned transaction preparation on paid tiers.

What you can do: Check native and token balances for a wallet on Stacks, Celo or Base, and fetch live prices with 24h change for assets such as STX, CELO, ETH, USDC and WBTC (free tier). Aggregate a portfolio view across all three chains in one call (Pro). Build unsigned native or ERC-20/SIP-010 transfer transactions (Pro). Prepare an unsigned ERC-20 token deployment transaction on Celo or Base (Team).
When to use it: Useful when an assistant needs to look up multichain wallet balances or token prices, or draft transfer and token-deployment transactions for a user to sign in their own wallet. It suits Web3 workflows spanning Stacks, Celo and Base rather than a single chain.
Requirements: Runs locally via npx, so Node.js is needed. No RPC or API keys are required for basic use; public RPC endpoints are used. A MULTICHAIN_LICENSE_KEY environment variable is optional: omit it for the free tier, or supply a paid license key to unlock portfolio, transfer and deployment tools.

Before you install

Paid tiers cost money (Pro and Team are monthly subscriptions) and are unlocked by the MULTICHAIN_LICENSE_KEY secret, which should be kept private. Write tools only return unsigned transactions, so signing stays with the user's wallet, but the assistant can still draft transfers and token deployments that spend real funds if signed. Wallet addresses and queries are sent to public chain RPC providers.

Installation

In SourceWeft

Open multichain-mcp in the dashboard and add it to a workspace.
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.

@wkalidev/multichain-mcp

[multichain-mcp MCP server] [multichain-mcp MCP server]

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

Tools included

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

Claude Desktop setup

Add to your claude_desktop_config.json:

json

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

{  "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:

json

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

{  "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" })

"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..." } })

"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..." })

"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"] })

"What are the current prices of STX, CELO and ETH?"→ get_prices({ symbols: ["STX", "CELO", "ETH"] })

Networks

No API keys required for basic usage.

Programmatic use

typescript

import { getBalance, getPortfolio, getPrices } from "@wkalidev/multichain-mcp";
