The macOS app, which has already garnered over 16,000 npm downloads and offers 251 tools, enables users to automate repetitive tasks by simply describing workflows to their AI, which then executes steps like reading WhatsApp messages, writing to Excel, and sending emails automatically.", "body_md": "LMCP gives your AI **direct access to your desktop apps** — Mail, Calendar, Contacts, Teams, Outlook, Excel and more. Works with Claude, ChatGPT, Cursor, VS Code and any MCP client — all running locally, no code or API keys.\n\nSet up in 2 minutes. Your data never leaves your machine — no cloud, no tokens, no passwords to share. GDPR & CCPA compliant by architecture.\n\nSigned & notarized · macOS 13+\n\n16K+ npm downloads · 251 tools · 100% local & private · macOS 12+ · Windows 10+ · Linux\n\nSteve H.\n\nStrategic Advisor\n\n“This is AMAZING! My daily work can all be managed from my key apps now.”\n\nHow it works\n\nSpot any repetitive task: orders arriving via WhatsApp, client emails to log, invoices to file, reports to write. No technical knowledge needed — just describe the pattern to your AI.\n\nYour AI maps the workflow to LMCP tools — read WhatsApp, write to Excel, send email, create reminders — and executes each step in sequence, automatically.\n\nAll 251 tools run locally. Your data never leaves your machine. Trigger workflows on demand, on a schedule, or as part of a larger agent pipeline.\n\nWhat’s included\n\nDirect access to your native apps and Microsoft suite.

Works directly with your local Slack data.\n\nRead/send email, manage calendar, and search your organization directory via Microsoft 365 — device code login, works with Outlook.com and work accounts.\n\nSearch and manage incidents, add comments, and search the Knowledge Base — Basic auth stored locally, no cloud middleman.\n\nSearch notes, list notebooks, and read or create content in Evernote — secure OAuth login, no password shared with AI.\n\nLMCP is extensible by design. Any local resource can be bridged to AI.\n\nMenu bar app — status at a glance\n\nPrivacy by design\n\nMost AI productivity tools send your data to cloud servers. LMCP reads your apps directly on your device — everything stays local.\n\nReal automations\n\nThe bottleneck\n\nWhatsApp orders arrive all day — someone copies them manually into the orders spreadsheet\n\nTell your AI:\n\n\"Read today's WhatsApp orders and add each one to the orders Excel file.\"\n\nAI reads WhatsApp chats, extracts customer, items and amounts, writes each row to Excel — no manual entry.\n\nThe bottleneck\n\nClient emails pile up and follow-ups fall through the cracks\n\nTell your AI:\n\n\"Check unread client emails, log each one in the CRM spreadsheet and create a follow-up reminder.\"\n\nAI reads Mail, writes to Excel, creates Reminders — every new client email handled without app switching.\n\nThe bottleneck\n\nInvoices arrive by email but filing them to the right OneDrive folder is tedious manual work\n\nTell your AI:\n\n\"Find today's invoice emails, save attachments to OneDrive/Finance/2026 and mark them as filed.\"\n\nAI reads Mail, saves each PDF to the right OneDrive folder, flags the email — done in seconds.\n\nThe bottleneck\n\nBefore any client call, 15 min digging through Teams, email and files for context\n\nTell your AI:\n\n\"What do we know about Acme Corp? Check emails, Teams conversations, and OneDrive files.\"\n\nAI searches three sources simultaneously and gives you a full briefing in under 10 seconds.\n\nThe bottleneck\n\nEvery morning, 20 minutes reading overnight emails, calendar and messages to plan the day\n\nTell your AI:\n\nScheduled daily at 8am: \"Summarize overnight emails, today's meetings and unread WhatsApp messages.\"\n\nAI runs on schedule, reads all three sources, sends a daily briefing to your inbox — before you open your laptop.\n\nThe bottleneck\n\nEvery Friday, 1 hour manually writing the weekly status report for the whole team\n\nTell your AI:\n\nScheduled every Friday at 4pm: \"Write the weekly report from this week's emails, Teams chats and meetings.\"\n\nAI aggregates the week across all sources, drafts the report, and posts it to the Teams channel — automatically.\n\nThe bottleneck\n\nSales pipeline review requires manually checking emails and Teams for each open deal\n\nTell your AI:\n\n\"Update the pipeline: check emails and Teams for each open deal and flag anything that needs action today.\"\n\nAI reads Mail and Teams per deal, updates the Excel tracker, flags urgent items — full review in 2 minutes.\n\nThe bottleneck\n\nDaily standup updates are inconsistent — people forget or write too little context\n\nTell your AI:\n\nScheduled daily at 9am: \"Read yesterday's activity from calendar, emails and Teams and post the standup.\"\n\nAI reads three sources, drafts each update, posts to the Teams standup channel — every morning, without anyone lifting a finger.\n\nUse from anywhere\n\nMost cloud AI clients can't reach localhost. The optional Cloud Relay creates an encrypted tunnel from your device to LMCP's backend, so ChatGPT, Claude.ai web, or any MCP-compatible cloud client can call your data tools — with the data still coming from your machine, never stored.\n\nWhat users say\n\n“This is AMAZING! My daily work can all be managed from my key apps now. The OmniFocus integration was the missing piece.”\n\nSteve H.\n\nStrategic Advisor\n\nOmniFocus + Mail + Calendar user\n\n“The no-tokens part is huge. Setting up Graph API and dealing with auth flows is what usually kills these setups for me before I even start.”\n\nLisa S.\n\nSoftware Engineer\n\nTeams + OneDrive user\n\n“Finally an AI tool that doesn't require sending my client emails to some random server.

Open Composer (⌘I) and switch the mode selector to **Agent**. Chat and Edit modes don't expose MCP tools.\n\nClaude Desktop / Claude Code\n\nWorks out of the box after install. Restart Claude Desktop once. In Claude Code, MCP tools are available immediately in new sessions.\n\nVS Code / Windsurf / Zed\n\nConfigured automatically. In VS Code with GitHub Copilot, enable MCP in settings and use Agent mode in the chat panel.\n\nWhat’s next\n\nNo APIs to configure. No tokens to manage. Just tell us what app you need connected — we build it with the same local-first, zero-cloud approach.\n\n\"Find the Q1 report in my Drive\"\n\n\"Search my wiki for the deploy guide\"\n\n\"Reply to Marco in the design channel\"\n\n\"Find photos from the last conference\"\n\nroadmap.spotify\n\nEvery integration follows one rule: **your data never leaves your device**.
