Tidesman: Native MCP Server for Apple's Container Tool

LinkTool

Tidesman is a free, native MCP server for Apple Silicon Macs that lets AI assistants manage Linux containers running on Apple's container engine. Instead of parsing CLI text output, it directly links against Apple's Swift client library and communicates locally over stdio.

Key points

  1. Links directly to Apple's Swift client library to return structured data rather than scraped CLI text
  2. Three security modes control execution: read-only (default), safe (lifecycle and exec without deletes), and full (includes deletion and pruning)
  3. Host directory mounts are disabled by default and require explicit allowlisting via --allow-host-mounts
  4. Every invocation is recorded in a local audit log detailing actions, arguments, and removed items
  5. Exposes 20 distinct tools covering system diagnostics, container lifecycle, logs, and image management
  6. Requires macOS 26 'Tahoe', Apple Silicon, and Apple's container engine pre-installed

Why it matters

AI coding assistants often struggle with fragile CLI output scraping when interacting with containers. Tidesman solves this by providing structured results through native libraries alongside granular safety modes, preventing catastrophic accidental deletes during autonomous agent runs.

Analysis

Tidesman demonstrates best practices for local MCP servers: it eschews network sockets entirely by using stdio, arrives signed and notarized for macOS, and transparently annotates tool risk levels. The tiered access model (--mode flag) lets developers safely experiment with autonomous debugging without giving models carte blanche over system state.
