It exposes Thirdweb's capabilities as tools the AI can call directly from your editor or CLI.

How do I install Thirdweb MCP with Claude Code?

The fastest way is the MCPizy CLI: run `mcpizy install thirdweb` and MCPizy will add the server to your `.claude.json` automatically. You can also install it manually by adding an entry under `mcpServers` in `.claude.json` with the command `pip install thirdweb-mcp` and restarting Claude Code.

Is Thirdweb MCP free?

Yes. The Thirdweb MCP server is free and open source (see the GitHub repository linked on this page). You may still need a Thirdweb account or API key to connect the server to the underlying service, but the MCP layer itself has no MCPizy subscription cost.

Does Thirdweb MCP work with Cursor and Windsurf?

Yes. Any MCP-compatible client works — including Claude Code, Claude Desktop, Cursor (via `.cursor/mcp.json`), Windsurf, VS Code with Copilot Chat, and custom agents built on the MCP SDK. The same install command targets all of them; only the config file path differs.
