Lumo Copilot v0.1.8

Lumo Copilot v0.1.8 — Lumo can use external tools now (MCP).

What's new
Lumo speaks the Model Context Protocol — the same open standard Claude Code and
other tools use — so it can borrow tools from external MCP servers instead of
being limited to its six built-ins.

Add one under Settings → Permissions → Tool servers (MCP). For example, the
official filesystem server:

• Name: files
• Command: npx
• Arguments: -y @modelcontextprotocol/server-filesystem ~/Documents

Servers start with the app, and Lumo shows how many tools each one offers.

Three deliberate limits
This is the one feature that can reach outside your machine, so it's built
carefully:

1. You add every server yourself. Nothing is auto-discovered or enabled by
   default.
2. Every MCP call still asks you first — the same approval card as running a
   shell command, showing which tool and what arguments.
3. Only capable models get them. Testing showed smaller local models already
   mishandle six tools, and a longer list makes them worse — so MCP tools go only
   to models that handle tools well, capped at 12 at a time.

A word of caution: an MCP server is a separate program running with your
permissions, and many of them use the internet. Only add ones you trust. Lumo's
own chat still runs entirely on your Mac.

Install / update
Existing installs update automatically. New installs: right-click the app → Open
