mcptoon v0.7.2 — one-line installers, Agent Plugins, honest token numbers

mcptoon v0.7.2 is out, and this launch needed an update more than the changelog.

What actually changed:

- One-line installers: curl -fsSL https://raw.githubusercontent.co... | bash (macOS/Linux) and irm https://raw.githubusercontent.co... | iex (Windows). Handles pipx, PATH, and PEP 668 automatically, then drops you into mcptoon quickstart.

- Agent Plugins spec support: install a plugin once, every agent gets its skills exposed as MCP prompts.

- MCP 2026-07-28 spec: server/discover negotiation, stateless _meta, MRTR requestState.

The honest token framing (we took community criticism seriously on this):

The headline saving is architecture, not serialization - full tool schemas never enter your model's context. Measured with tiktoken cl100k_base on a real 255-tool / 50-server config: 71,929 tokens (raw JSON) -> 8,282 with --slim (names + parameter types, -88.5%) -> 123 with --compact (names only, -99.8%). The honest headline is the slim number.

Reproduce on your machine: pip install mcptoon && mcptoon demo - it runs the before/after live on your own config.

What breaks when you manage lots of MCP servers? Genuinely want to know.
