How it works

From idea to running automation

01

01

You identify the workflow

Spot 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.

02

02

Your agent designs the steps

Your AI maps the workflow to LMCP tools — read WhatsApp, write to Excel, send email, create reminders — and executes each step in sequence, automatically.

03

03

LMCP executes locally

All 183 tools run locally. Your data never leaves your machine. Trigger workflows on demand, on a schedule, or as part of a larger agent pipeline.

❌ No cloud servers. No third parties. Ever.

Real automations

Describe the workflow once. Your agent runs it every time.

The bottleneck

WhatsApp orders arrive all day — someone copies them manually into the orders spreadsheet

Tell your AI:

"Read today's WhatsApp orders and add each one to the orders Excel file."

AI reads WhatsApp chats, extracts customer, items and amounts, writes each row to Excel — no manual entry.

The bottleneck

Client emails pile up and follow-ups fall through the cracks

Tell your AI:

"Check unread client emails, log each one in the CRM spreadsheet and create a follow-up reminder."

AI reads Mail, writes to Excel, creates Reminders — every new client email handled without app switching.

The bottleneck

Invoices arrive by email but filing them to the right OneDrive folder is tedious manual work

Tell your AI:

"Find today's invoice emails, save attachments to OneDrive/Finance/2026 and mark them as filed."

AI reads Mail, saves each PDF to the right OneDrive folder, flags the email — done in seconds.

The bottleneck

Before any client call, 15 min digging through Teams, email and files for context

Tell your AI:

"What do we know about Acme Corp? Check emails, Teams conversations, and OneDrive files."

AI searches three sources simultaneously and gives you a full briefing in under 10 seconds.

The bottleneck

Every morning, 20 minutes reading overnight emails, calendar and messages to plan the day

Tell your AI:

Scheduled daily at 8am: "Summarize overnight emails, today's meetings and unread WhatsApp messages."

AI runs on schedule, reads all three sources, sends a daily briefing to your inbox — before you open your laptop.

The bottleneck

Every Friday, 1 hour manually writing the weekly status report for the whole team

Tell your AI:

Scheduled every Friday at 4pm: "Write the weekly report from this week's emails, Teams chats and meetings."

AI aggregates the week across all sources, drafts the report, and posts it to the Teams channel — automatically.

The bottleneck

Sales pipeline review requires manually checking emails and Teams for each open deal

Tell your AI:

"Update the pipeline: check emails and Teams for each open deal and flag anything that needs action today."

AI reads Mail and Teams per deal, updates the Excel tracker, flags urgent items — full review in 2 minutes.

The bottleneck

Daily standup updates are inconsistent — people forget or write too little context

Tell your AI:

Scheduled daily at 9am: "Read yesterday's activity from calendar, emails and Teams and post the standup."

AI reads three sources, drafts each update, posts to the Teams standup channel — every morning, without anyone lifting a finger.

Use from anywhere

ChatGPT, Claude.ai web — connected to your machine

Most 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.

✓Opt-in toggle in the menu bar — off by default, privacy-first

✓Encrypted end-to-end via WebSocket — backend never persists tool responses

✓Works with ChatGPT Plus/Team/Enterprise, Claude.ai web, and any MCP cloud client

“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.”

“Finally an AI tool that doesn't require sending my client emails to some random server. GDPR compliance by architecture, not by policy — that's exactly what we needed.”

Client setup notes

⚡

Cursor — Agent mode required

LMCP tools only appear in Agent mode. Open Composer (⌘I) and switch the mode selector to Agent. Chat and Edit modes don't expose MCP tools.

🤖

Claude Desktop / Claude Code

Works out of the box after install. Restart Claude Desktop once. In Claude Code, MCP tools are available immediately in new sessions.

🪟

VS Code / Windsurf / Zed

Configured automatically. In VS Code with GitHub Copilot, enable MCP in settings and use Agent mode in the chat panel.

What’s next

Request it. We ship it.

No 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.
