Overview

Rune Kit implements the Model Context Protocol in Rust, executing untrusted agent tools in Extism WebAssembly sandboxes with strict memory boundaries and stdio JSON-RPC multiplexing.

## Capabilities

1. 01 ### Memory Isolation

   Tools execute in sandboxed wasm32-wasip1 containers with explicit capability grants.
2. 02 ### High Concurrency

   Asynchronous multiplexing handles dozens of concurrent tool calls with negligible latency.
3. 03 ### MCP Native

   Full compliance with the latest Model Context Protocol specification.
