What it does

Mithril provides a secure, structurally bounded alternative to the standard unrestricted shell tool. Instead of passing raw strings to bash, it exposes specific, typed tools that run within OS-level sandboxes (BubbleWrap on Linux, sandbox-exec on macOS), preventing prompt injection and accidental system damage.

Tools

Cat: Reads files from the project directory.
Grep: Searches for patterns within files.
GitStatus: Checks the current state of the git repository.
CargoTest: Runs Rust tests.
Ls: Lists files and directories.
Rm: Safely removes files (requires approval).
GoVet: Performs static analysis on Go code.
Pytest: Executes Python tests.

  "mcpServers": {

      "command": "mithril",
