Quick start

1. Get your API key

Open Integrations

In the LinkedCamp app, go to Settings → Integrations → API. API access needs a plan with Pro features (Pro or Agency) and the Integrations permission.

Copy the API key

It’s a UUID, for example 3f7c1a92-8e4b-4d1f-9c0a-2b5e8d4f6a11.

Keep it secret

Treat it like a password. Rotate it from the same page if it ever leaks.

The key acts as you. Anyone who has it can launch campaigns and send messages from your account. Rotating it from Integrations invalidates the old key immediately. Billing, agency admin and team management stay blocked on the server whatever the key.

2. Connect your client

Claude
Claude Code
Cursor / Windsurf / Zed
ChatGPT

In Claude on the web or desktop, add it as a custom connector and sign in. You don’t paste the key into a config file.

Open connector settings

Settings → Connectors → Add custom connector.

Paste the endpoint

https://mcp.linkedcamp.com/mcp

Authorize

Claude opens a LinkedCamp sign-in page. Paste your API key. It’s the only credential the page accepts.

Use it

Start a chat: “List my active campaigns and tell me which one has the best reply rate.”

The connector uses OAuth 2.1 with PKCE. Your API key is encrypted inside the access token and never appears in a URL or a log line.

claude mcp add --transport http linkedcamp https://mcp.linkedcamp.com/mcp \
  --header "X-Api-Key: YOUR_API_KEY"

Then check that it registered:

claude mcp list

Add the server to your MCP config. For Cursor, that’s ~/.cursor/mcp.json:

{
  "mcpServers": {
    "linkedcamp": {
      "url": "https://mcp.linkedcamp.com/mcp",
      "headers": { "X-Api-Key": "YOUR_API_KEY" }
    }
  }
}

The easiest way is the official plugin:

LinkedCamp for ChatGPT

Install the plugin to run campaigns, work the inbox and pull analytics from a ChatGPT chat, with no config file.

You can also add the server as a custom connector:

Open connector settings

Settings → Connectors → add a custom connector using the Streamable HTTP transport.

Paste the endpoint

https://mcp.linkedcamp.com/mcp

Authorize

ChatGPT opens a LinkedCamp sign-in page. Paste your API key. It’s the only credential the page accepts.

Use it

Start a chat: “Show me the campaigns that replied best this month.”

Custom connectors aren’t available on every ChatGPT plan, and on some they’re behind developer mode. If you can’t see the option, check your plan.

3. First conversation

Ask the assistant to call whoami first. It reports your plan and permissions, which decide which tools and sequence steps you can use. Then try:

“Which of my campaigns has the best acceptance rate this month?”
“Draft replies to my unread interested leads.”
“Create a draft campaign for CTOs in fintech and show me the sequence before launching.”

Authentication

Client type	How the key is sent
Claude and ChatGPT connectors	OAuth 2.1 + PKCE. You paste the key once on the LinkedCamp sign-in page.
Config-file clients (Claude Code, Cursor, Windsurf, Zed)	`X-Api-Key` HTTP header on every request.
