Connector ecosystem: Microsoft 365, Slack, Notion, Dropbox + MCP

[smshagor-dev]

Goal

Expand OpenMindAI from Google Workspace + GitHub into a broader user-controlled connector ecosystem while preserving local/offline-first AI behavior.

Built-in connectors

• Microsoft 365 via Microsoft Graph: account, Outlook mail, OneDrive, Calendar, Contacts
• Slack: workspace/account, channels, history, search, send/update/delete messages
• Notion: workspace/account, search, pages/blocks, data sources, comments, create/update content
• Dropbox: account, list/search/download/upload/move/delete files

Generic connector layer

• MCP over Streamable HTTP / HTTP JSON-RPC
• Secure optional bearer token storage
• tools/list discovery
• tools/call execution
• Explicit user approval before MCP tool calls marked or treated as remote writes
• Request/result size and timeout bounds

Security / UX

• Secrets/tokens stay in OS credential store, never SQLite/plain files/chat history
• Least-privilege setup guidance
• Provider status/connect/disconnect UI in Settings → Connections
• Provider/action selection in Connected Work
• Existing Google/GitHub behavior unchanged
• Offline local AI remains functional

Quality gates

• Unit/regression tests
• Frontend lint/build
• Rust fmt/Clippy/tests on Windows/macOS/Linux
• Windows Tauri application build
• Dependency audit + CodeQL

Manual trust gates

• Real Microsoft Entra app/account live test
• Real Slack token/workspace live test
• Real Notion connection/workspace live test
• Real Dropbox app/account live test
• Real remote MCP server live test

External service registration/approval remains a user/admin/provider step and must not be represented as completed by CI alone.
