Claude's word for MCP servers — the plug layer that lets the desktop app read your mail, your calendar and your actual files.

Pick this when

You want an assistant that acts on your real data on your real machine, not just talks about it.

What makes it different

Reaches the local filesystem and CPU — the whole reason connectors are desktop-only

Granular permissions: allow-once vs always-allow, per action and per directory

Works on free accounts; pick Haiku to stretch the token allowance

What it does

Connects first-party servers (Gmail, Google Calendar, filesystem) from a built-in directory

Accepts custom connectors by pasting a hosted server URL

Shows the tool-use trace so you can see exactly what it called

What it does not do

Common wrong expectations

Doesn't register a new connector until you fully quit and relaunch the app

Doesn't escape its sandbox — the desktop-declutter demo failed because minimal privilege was working

Doesn't support every connector on every OS (Control Chrome was Mac-only)

Where it sits in a stack

The action layer of daily assistant work: calendar triage, inbox summarizing, file organization.

Shelf

MCP & connectors

Our status · using

Desktop Commander and filesystem access are how every sitting reaches the _CLASSES tree.

For your projects

The permission model in BC5 is the one already in force here — worth applying its discipline (allow-once while learning, always-allow once trusted) to any new server added to the stack.
