thirdweb MCP Server

A Model Context Protocol (MCP) server implementation for thirdweb services integration. This server allows you to integrate thirdweb's tools with any MCP-compatible client.

Overview

thirdweb MCP provides a unified interface to access thirdweb's suite of blockchain tools and services through the standardized Model Context Protocol. It supports multiple communication transports and can be integrated with various thirdweb services:

• Nebula: Autonomous onchain execution - real-time on-chain analysis, code generation and contract interactions
• Insight: Blockchain data analysis capabilities for real-time on-chain data
• Engine: Integration with thirdweb's backend infrastructure for contract deployments and interactions
• EngineCloud: Cloud-based engine operations for server wallets, contract interactions, and transaction management
• Storage: Decentralized storage capabilities for uploading and retrieving data via IPFS

Installation

Prerequisites

• Python 3.10 or higher
• uv

Run with uvx

THIRDWEB_SECRET_KEY=... \
    uvx thirdweb-mcp

Install and run with pipx

pipx install thirdweb-mcp

THIRDWEB_SECRET_KEY=... \
    thirdweb-mcp

Install from source

git clone https://github.com/thirdweb-dev/ai.git thirdweb-ai
cd thirdweb-ai/python/thirdweb-mcp
uv sync

Configuration

The thirdweb MCP server requires configuration based on which services you want to enable:

1. thirdweb Secret Key: Required for Nebula, Insight, Storage, and EngineCloud services. Obtain from the thirdweb dashboard.
2. Chain IDs: Blockchain network IDs to connect to (e.g., 1 for Ethereum mainnet, 137 for Polygon).
3. Engine Configuration: If using the Engine service, you'll need the Engine URL and authentication JWT.
4. EngineCloud Configuration: For EngineCloud operations, you may need the Vault Access Token for server wallet operations.

You can provide these through command-line options or environment variables.

Usage

Command-line options

# Basic usage with default settings (stdio transport with Nebula and Insight)
THIRDWEB_SECRET_KEY=... thirdweb-mcp 

# Using SSE transport on a custom port
THIRDWEB_SECRET_KEY=... thirdweb-mcp --transport sse --port 8080

# Enabling all services with specific chain IDs
THIRDWEB_SECRET_KEY=... thirdweb-mcp --chain-id 1 --chain-id 137 \
    --engine-url YOUR_ENGINE_URL \
    --engine-auth-jwt YOUR_ENGINE_JWT \ 
    --engine-backend-wallet-address YOUR_ENGINE_BACKEND_WALLET_ADDRESS \
    --vault-access-token YOUR_VAULT_ACCESS_TOKEN

Environment variables

You can also configure the MCP server using environment variables:

• THIRDWEB_SECRET_KEY: Your thirdweb API secret key
• THIRDWEB_ENGINE_URL: URL endpoint for thirdweb Engine service
• THIRDWEB_ENGINE_AUTH_JWT: Authentication JWT token for Engine
• THIRDWEB_ENGINE_BACKEND_WALLET_ADDRESS: Wallet address for Engine backend
• THIRDWEB_VAULT_ACCESS_TOKEN: Vault access token for EngineCloud server wallet operations

Integration with Claude Desktop

To add this MCP server to Claude Desktop:

1. Install the MCP: pipx install thirdweb-mcp

2. Create or edit the Claude Desktop configuration file at:

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%\Claude\claude_desktop_config.json
   • Linux: ~/.config/Claude/claude_desktop_config.json

3. Add the following configuration:

   {
     "mcpServers": {
       "thirdweb-mcp": {
         "command": "thirdweb-mcp",
         "args": [], // add `--chain-id` optionally
         "env": {
           "THIRDWEB_SECRET_KEY": "your thirdweb secret key from dashboard",
           "THIRDWEB_ENGINE_URL": "(OPTIONAL) your engine url",
           "THIRDWEB_ENGINE_AUTH_JWT": "(OPTIONAL) your engine auth jwt",
           "THIRDWEB_ENGINE_BACKEND_WALLET_ADDRESS": "(OPTIONAL) your engine backend wallet address",
           "THIRDWEB_VAULT_ACCESS_TOKEN": "(OPTIONAL) your vault access token for EngineCloud"
         },
       }
     }
   }

4. Restart Claude Desktop for the changes to take effect.
