# La Growth Machine MCP server: LinkedIn and email outreach from Claude and ChatGPT

Connect La Growth Machine (LGM), the multichannel sales outreach platform, to Claude, ChatGPT, Claude Code, Cursor or Codex. Build audiences from Sales Navigator, write and edit campaign sequences, clear your LinkedIn and email inbox, and measure which campaigns turn replies into meetings and pipeline. Built for GTM engineers, RevOps, sales managers and SDR teams.

**Server URL: `https://mcp.lagrowthmachine.com`**. Sign in with your La Growth Machine account (OAuth), no API key needed. See [Connect](#connect).

**Reads and writes.** Read tools run without confirmation. Every write (sending a message, editing a campaign, spending credits) asks you first.

## Connect

Paste one URL, sign in to La Growth Machine, done. No API key to copy, nothing to install. You need an active La Growth Machine workspace.

```
https://mcp.lagrowthmachine.com
```

### Claude (claude.ai, Desktop, mobile)

1. In Claude, open **[Customize > Connectors](https://claude.ai/customize/connectors)** and search **La Growth Machine** in the directory.
   Not listed? Click **Add custom connector**, name it *La Growth Machine* and paste the URL above. On Team and Enterprise plans, an owner may have to add it first.
2. Click **Connect**, sign in to La Growth Machine and approve. You are back in Claude, ready to ask.

### ChatGPT

1. In ChatGPT, open **Settings > Apps** and create an app (developer mode must be on; on Business and Enterprise plans a workspace admin enables it).
2. Name it *La Growth Machine*, paste the URL above and choose **OAuth** authentication.
3. Click **Connect**, sign in to La Growth Machine and approve.

### Claude Code

```bash
claude mcp add --transport http --scope user LaGrowthMachine https://mcp.lagrowthmachine.com
```

Then type `/mcp` in Claude Code, pick **LaGrowthMachine** and sign in from your browser.

### Cursor

Add the server to `~/.cursor/mcp.json` (or **Cursor Settings > MCP > Add new MCP server**):

```json
{
  "mcpServers": {
    "LaGrowthMachine": { "url": "https://mcp.lagrowthmachine.com" }
  }
}
```

Cursor asks you to sign in to La Growth Machine on first use.

### Codex

```bash
codex mcp add LaGrowthMachine --url https://mcp.lagrowthmachine.com
codex mcp login LaGrowthMachine
```

### Any other MCP client

Any client that supports remote MCP servers (Streamable HTTP) and OAuth works with the same URL. Without OAuth support, use an [API key](#api-key-clients-without-oauth).

## What you can ask Claude

**Build audiences and leads**
- "Create an audience called 'DACH VPs of Sales' from this Sales Navigator search URL, using my main LinkedIn identity."
- "Import everyone who commented on this LinkedIn post into a new audience."
- "Add this LinkedIn profile as a lead in the 'Q4 partners' audience with a note about our last call."
- "Find a pro email for Marie Dupont at Acme." (credit cost is shown and confirmed before spending)

**Write and manage campaigns**
- "Duplicate 'VP Sales Q2', rename it 'VP Sales Q3' and assign the new audience."
- "Show me the sequence of 'DACH Enterprise' and rewrite step 3 so it is shorter and ends with a question."
- "Turn on HubSpot sync and skip already-contacted leads on this campaign, then resume it."

**Handle replies**
- "Which conversations are waiting for my reply? Draft an answer for each."
- "Send a LinkedIn voice message to John Smith from my main identity."
- "Snooze every 'not now' conversation for two weeks and archive the out-of-office ones."
- "Which calls do I have to make? I just reached Jean Dupont, he's interested — close his call task."

**Analyze performance**
- "Compare reply rates and conversions across my running campaigns and flag anything under 10% acceptance."
- "Which step of 'DACH Enterprise' loses the most leads?"
- "Give me the reply rate per step and per channel for the last 30 days." (read-only SQL over your activity logs)

## Who it is for

- **GTM and growth engineers, RevOps**: you run the outbound stack (Clay, HubSpot, La Growth Machine) and want campaign data and actions in the same chat as the rest of your tooling.
- **Heads of sales and team leads**: pipeline contribution per campaign without opening a dashboard.
- **SDRs and AEs**: one place to handle LinkedIn and email conversations and follow-ups.

## Go deeper with LGM Skills

The MCP gives Claude your data. [LGM Skills](https://github.com/laGrowthMachine/gtm-system) give it the method. **Campaign Analyzer** pulls stats and sequences through this MCP and returns prioritised fixes (weak steps, missing follow-ups, targeting mismatches). Segmentation Advisor and Copywriting Coach are next.

## Advanced setup

### API key (clients without OAuth)

Pass an API key from [Settings > API](https://app.lagrowthmachine.com/settings/integrations/api) in the `X-LGM-API-KEY` header:

```bash
claude mcp add --transport http --scope user LaGrowthMachine \
  https://mcp.lagrowthmachine.com \
  --header "X-LGM-API-KEY: <your-api-key>"
```

Replace `claude mcp add` with your client's equivalent command.

## FAQ

**Does La Growth Machine have an MCP server?**
Yes. This is the official, open-source (Apache 2.0) MCP server, listed in the Claude connectors directory and usable with any MCP client at `https://mcp.lagrowthmachine.com`. More on the [product page](https://lagrowthmachine.com/mcp/?utm_source=github&utm_medium=readme&utm_campaign=mcp).

**Can Claude send LinkedIn messages or emails through La Growth Machine?**
Yes, from any identity connected to your LGM account, text or voice on LinkedIn, new thread or reply by email. Claude asks for confirmation before every send.

**Can I create a campaign from scratch?**
Today Claude duplicates an existing campaign, then edits its steps, audience and settings. Creating from a blank sequence is on the roadmap.

**Does it work with HubSpot or Pipedrive?**
Yes. Claude can enable or disable CRM sync per campaign. Deals and contacts stay in your CRM; LGM pushes outreach activity to it.

**Is it free?**
The server is free and open source. You need an active La Growth Machine workspace. Enrichment tools spend LGM credits and always preview the cost first.

**What data leaves my account?**
Your data goes only to your AI client during the conversation. The server sends one first-party analytics event per tool call (tool name only, no content). See Privacy below.

## Privacy

This connector calls the [La Growth Machine](https://lagrowthmachine.com?utm_source=claude&utm_medium=mcp&utm_campaign=claude-store) API on your behalf, over OAuth or your API key. Data is fetched on demand and used only inside your AI conversation. Nothing is stored beyond your credentials (OS keychain for the desktop extension). Your data is not shared with any third party.

Full policy: [lagrowthmachine.com/privacy-policy](https://lagrowthmachine.com/privacy-policy?utm_source=claude&utm_medium=mcp&utm_campaign=claude-store)

### Usage analytics and opt-out

On each tool call the server sends one first-party event to `https://apiv2.lagrowthmachine.com/flow/tracking/mcp`: the event name (`mcp_tool_called`, or `mcp_preference_saved` for `save_identity_preference`) and the tool name. No conversation content, lead data, message bodies or arguments. The request is fire-and-forget and never blocks a result.

Opt out: enable **"Disable usage analytics"** in the extension settings, or set `LGM_DISABLE_TELEMETRY=true` for self-hosted and other clients.
