About Thirdweb
Thirdweb MCP Server is a Model Context Protocol (MCP) implementation that provides a unified interface for integrating thirdweb's suite of blockchain tools and services. It supports multiple communication transports (stdio, SSE) and can be used with any MCP-compatible client, such as Claude Desktop. The server enables autonomous onchain execution via Nebula, real-time blockchain data analysis via Insight, contract deployments and interactions via Engine, cloud-based engine operations via EngineCloud, and decentralized IPFS storage via Storage. Requires Python 3.10+ and a thirdweb secret key for configuration.
Key Features

FAQ
What is thirdweb MCP Server?
It is a Model Context Protocol (MCP) server that provides a unified interface to access thirdweb's blockchain tools and services, such as Nebula, Insight, Engine, EngineCloud, and Storage.
How do I install thirdweb MCP Server?
You can install it via pipx (`pipx install thirdweb-mcp`) or run it with uvx (`uvx thirdweb-mcp`). Alternatively, clone the repository and install from source using `uv sync`.
What configuration is required?
At minimum, you need a thirdweb secret key (obtainable from the thirdweb dashboard). Additional configuration includes chain IDs, Engine URL and JWT, EngineCloud vault access token, depending on which services you enable.
Can I use this with Claude Desktop?
Yes, once installed via pipx, you can add the MCP server to Claude Desktop's configuration file (e.g., `~/Library/Application Support/Claude/...`).
What transport protocols are supported?
It supports stdio (default) and SSE transport. You can specify SSE with `--transport sse` and set a custom port with `--port`.
