Multi Wallet MCP Server

Thryx MCP Servers

Smart contract scanning, multi-wallet treasury, DeFi orchestration, and gas paymaster integration for AI agents on Base.

A monorepo of four MCP (Model Context Protocol) servers built for AI agents that need to actually do things on-chain — read contracts, manage wallets, execute swaps, sponsor gas — instead of just generating text about them.

All four are published to npm and combined are pulling ~850 monthly downloads as of April 2026.

Servers

Plus @thryx/mcp-shared — the shared rate-limiter, billing layer, and EVM helpers used by all four.

Install — 30 seconds per server

Add any of these to your MCP client config (Claude Desktop, Cursor, Continue, Cline, etc.):

{
  "mcpServers": {
    "contract-scanner": {
      "command": "npx",
      "args": ["@thryx/contract-scanner-mcp-server"]
    },
    "multi-wallet": {
      "command": "npx",
      "args": ["@thryx/multi-wallet-mcp-server"]
    },
    "defi-orchestrator": {
      "command": "npx",
      "args": ["@thryx/defi-orchestrator-mcp-server"]
    },
    "gas-paymaster": {
      "command": "npx",
      "args": ["@thryx/gas-paymaster-mcp-server"]
    }
  }
}

Restart your MCP client and the servers are live.

Free + Pro tiers

Every server has a free tier with rate limits and a Pro tier with no limits and additional tools. The free tier is genuinely useful — you do not need a Pro key to evaluate the servers or use them in personal projects.

Pro keys are linked to a thryx.fun purchase. Pass yours via the api_key parameter on any tool call, or set the THRYX_API_KEY environment variable in your MCP client config.

Free-tier limits per server (subject to change):

• contract-scanner — 5 scans/hour for scanner_analyze_contract and scanner_compare_contracts. scanner_check_address and scanner_decode_calldata are unlimited.
• multi-wallet — read operations unlimited, write operations rate-limited.
• defi-orchestrator — read operations unlimited, write operations rate-limited.
• gas-paymaster — sponsored-tx counts gated by tier.

What "MCP" means if you've never heard of it

Model Context Protocol is the open standard for connecting AI assistants to real tools. Instead of an AI agent generating "I would call your API like this…", it actually calls the API. Servers like the ones in this monorepo expose capabilities to any MCP-compatible client (Claude, Cursor, Cline, Continue, etc.) without each client needing custom integration code.

If you're building an AI agent that needs to read from or write to a Base/EVM chain — these servers save you from rebuilding all of it yourself.

Bootstrapping a complete on-chain agent in two minutes

The MCP servers are tools — but tools are most useful when they have a platform to act on. THRYX (the gasless token launchpad these servers were built for) exposes an open /api/agent/register endpoint that gives any AI agent a wallet, an API key, and pre-sponsored gas in a single HTTP call. No KYC, no email verification, no account recovery flow — one call, you're live on Base mainnet.

# 1. Register an agent on THRYX (one call → wallet + API key + gas)
curl -X POST https://thryx-launchpad.onrender.com/api/agent/register \
  -H "Content-Type: application/json" \
  -d '{"name": "my-agent"}'

# Response includes:
#   apiKey:  thryx_<base64url>
#   wallet:  0x...
#   gas:     "Gas is being sponsored to your wallet now (~5-10 seconds)"

// 2. Add the @thryx/* MCP servers to your client config (with the API key from step 1)
{
  "mcpServers": {
    "contract-scanner": {
      "command": "npx",
      "args": ["@thryx/contract-scanner-mcp-server"],
      "env": { "THRYX_API_KEY": "thryx_..." }
    },
    "multi-wallet": {
      "command": "npx",
      "args": ["@thryx/multi-wallet-mcp-server"],
      "env": { "THRYX_API_KEY": "thryx_..." }
    },
    "defi-orchestrator": {
      "command": "npx",
      "args": ["@thryx/defi-orchestrator-mcp-server"],
      "env": { "THRYX_API_KEY": "thryx_..." }
    },
    "gas-paymaster": {
      "command": "npx",
      "args": ["@thryx/gas-paymaster-mcp-server"],
      "env": { "THRYX_API_KEY": "thryx_..." }
    }
  }
}

That's it. Your agent has a funded wallet on Base, can scan any contract before interacting with it (scanner_analyze_contract), can launch its own token gaslessly (POST /api/launch), can buy/sell on the THRYX bonding curves, and can withdraw earnings to any address (POST /api/agent/withdraw).

The MCP servers and the THRYX platform are designed to compose. You can use either alone — the servers work against any Base contract and the platform accepts any wallet — but together they're the fastest path from "I want to build a Base on-chain agent" to "my agent just made its first onchain trade."

Building from source

git clone https://github.com/lordbasilaiassistant-sudo/mcp-servers.git
cd mcp-servers
cd shared && npm install && npm run build && cd ..
cd contract-scanner-mcp-server && npm install && npm run build && cd ..
# ... or any other server you want to work on

Each server is independently built and published. The shared package exports rate limiting, billing validation, EVM helpers, and chain configs.

Tech stack: TypeScript (strict), @modelcontextprotocol/sdk, ethers v6, zod for schema validation, vitest for tests, stdio transport. Builds with tsc only — no bundlers, no magic.

---

Status

• Production for the four servers above. Live on npm, in active use by AI agents on Base mainnet.
• In progress: token-deployer-mcp-server, webhook-worker (Cloudflare Worker for Stripe → API key delivery).
• Roadmap: x402-based pay-per-call for the Pro tools (replacing the Stripe webhook flow with USDC micropayments — no API keys to manage, no subscriptions to revoke, agents pay per execution).
