Integrations

Eight integrations ship and load today. Notion and Obsidian are built but currently shelved.

Integration	Tools	Tool group
GitHub	Sync issues, link a PR to a spec	`imports`
Slack	Post updates, digests, ingest a channel	`slack`
Trello	Import, export, sync a board	`trello`
Harvest	Time, budgets, profitability, utilisation	`harvest`
Grain	Import meeting notes and context	`imports`
Google Calendar	Calendar context	—
Design Tokens	Hands agents your design tokens	—
Voice Assistant	Voice input (Pro)	`voice`

Credentials

Two ways, depending on the plugin:

A bridge file in .mm/integrations/ — github.json, slack.json. Gitignored, so it stays local.
An environment variable — GITHUB_TOKEN (or gh CLI auth), GRAIN_API_TOKEN.

Each guide states which its plugin reads.

Most integration tools are opt-in: set MM_TOOL_GROUPS to the groups you want, comma-separated.

{ "env": { "MM_TOOL_GROUPS": "harvest,slack" } }

Un-listed tools still run when called by name — opting in only makes agents aware of them.
