Thirdweb MCP Server
Thirdweb MCP servers enable AI agents to interact with EVM blockchains via thirdweb services, supporting multi-chain data querying, wallet and contract operations, autonomous execution, and both hosted and self-hosted deployment options.
Overview
The Thirdweb MCP Server connects AI agents to the thirdweb ecosystem, enabling secure, standardized interactions with EVM-compatible blockchains. Through thirdweb services like Insight, Engine/EngineCloud, and Nebula, agents can query on-chain data, manage wallets, read/write contracts, and execute transactions autonomously.
Official Server:
Developed and maintained by Thirdweb
Key Features
Multi-Chain Onchain Data
Real-time queries across many EVM networks via Insight
Wallet & Contract Tools
Create server wallets, read ABI/state, and write to contracts
Autonomous Execution
Nebula enables agents to plan and execute complex onchain tasks
Hosted & Self-Hosted
Use the hosted MCP endpoint or run locally with Python tools
Available Tools
Quick Reference
| Tool | Purpose | Category |
|---|---|---|
list_server_wallets | List server wallets | Wallet |
create_server_wallet | Create a server wallet | Wallet |
get_wallet_balance | Get native/token balances | Wallet |
read_contract | Read contract state/ABI | Contract |
write_contract | Execute contract function | Contract |
get_contract_events | Fetch recent events | Data |
Detailed Usage
get_wallet_balance▶
Retrieve the native/token balance of a wallet on a given chain.
use_mcp_tool({
server_name: "thirdweb",
tool_name: "get_wallet_balance",
arguments: {
address: "0xYourWallet",
chainId: 1
}
});
read_contract▶
Read contract state or metadata using ABI and method parameters.
use_mcp_tool({
server_name: "thirdweb",
tool_name: "read_contract",
arguments: {
chainId: 1,
contractAddress: "0xContract",
function: "balanceOf",
params: ["0xYourWallet"]
}
});
write_contract▶
Execute a contract function using a server wallet (Engine/EngineCloud).
use_mcp_tool({
server_name: "thirdweb",
tool_name: "write_contract",
arguments: {
chainId: 137,
contractAddress: "0xContract",
function: "approve",
params: ["0xSpender", "1000000"],
wallet: "treasury"
}
});
Requires Engine configuration for transaction execution.
get_contract_events▶
Fetch recent events (logs) for a contract on a given chain.
use_mcp_tool({
server_name: "thirdweb",
tool_name: "get_contract_events",
arguments: {
chainId: 1,
contractAddress: "0xContract",
event: "Transfer",
fromBlock: "latest-500"
}
});
