star history
Wassette runs WebAssembly Components through the Model Context Protocol (MCP), enabling AI agents to safely invoke external tools without leaving their chat interface. Built on Wasmtime’s security sandbox, it provides browser-grade isolation for tool execution. Users configure their preferred AI agent to connect to Wassette, which then loads and executes Wasm components as callable tools.
