Run LinkedIn outbound from Claude: connect Sliq as an MCP server
Published:
Last updated:
You can run LinkedIn and email outbound from Claude by connecting Sliq as a custom MCP connector. In Claude, open Settings → Connectors, add a custom connector, and paste Sliq's MCP server URL: https://mcp.getsliq.com/mcp. Once connected, you ask Claude to find prospects, research them, and draft outreach through Sliq — and every message waits for your approval before it sends. Claude does the driving; you keep the final say. This guide walks through the setup for Claude, Claude Code, and ChatGPT.
Sliq is not the only LinkedIn tool with a Claude MCP — HeyReach has one too. The difference is what happens when Claude says "go." HeyReach launches a LinkedIn campaign that runs on its own. Sliq covers LinkedIn and email, and holds every drafted message for your approval first. If you want Claude to run your outbound without giving up the send button, that gate is the whole point.
What is the Sliq MCP server?
The Sliq MCP server is a public endpoint that gives an AI client — Claude, Claude Code, or ChatGPT — access to Sliq's outbound tools and data. MCP (Model Context Protocol) is the standard those clients use to connect to outside tools. Point a client at Sliq's MCP URL, sign in, and Claude can prospect, research, and draft LinkedIn and email outreach in Sliq on your behalf, with your approval gate intact.
The server URL is:
https://mcp.getsliq.com/mcp
That full path is the endpoint. Claude apps and Claude Desktop authenticate over OAuth when you sign in; Claude Code and other command-line clients authenticate with a Sliq API key (an sk_live_… token from your Sliq settings).
How to connect Sliq to Claude (claude.ai and Desktop)
Use this for the Claude web app and Claude Desktop:
- In Claude, open Settings → Connectors.
- Click Add custom connector.
- Paste the server URL
https://mcp.getsliq.com/mcpand add it. - Approve the Sliq sign-in when prompted.
That's it. Adding a custom connector requires a paid Claude plan (Pro, Max, Team, or Enterprise). Once it's connected, Claude can work with Sliq directly in your conversations.
How to connect Sliq to Claude Code
Claude Code connects from the command line. Run this in your terminal, using an API key from your Sliq settings:
claude mcp add --transport http sliq https://mcp.getsliq.com/mcp --header "Authorization: Bearer sk_live_YOUR_KEY"
Replace sk_live_YOUR_KEY with your own key. Claude Code now has Sliq's LinkedIn and email tools available, with the same approval gate on every send.
How to connect Sliq to ChatGPT
Sliq's MCP server works with ChatGPT too:
- In ChatGPT, open Settings → Connectors and turn on developer mode if needed.
- Add a custom connector and paste
https://mcp.getsliq.com/mcp. - Sign in to Sliq when prompted.
Custom connectors require a paid ChatGPT plan.
What you can do once Claude is connected
With Sliq connected, you drive outbound in plain language from your Claude conversation. For example:
- Find prospects. "Find heads of sales at seed-stage B2B SaaS companies in New York."
- Research and draft. "Research the top 20 and draft a LinkedIn connection note for each, referencing something specific about their company."
- Add email. "For anyone who accepts, draft a follow-up email."
- Review and approve. Claude queues each drafted message in Sliq. You approve, edit, or reject before any of it sends.
Claude handles the thinking and the drafting. The send stays behind your approval — so a Claude prompt can never fire off a message you haven't seen.
Sliq vs HeyReach for running LinkedIn outbound from Claude
Both connect to Claude through a native MCP server. They differ on channels and, most importantly, on whether a human approves each send.
| Sliq | HeyReach | |
|---|---|---|
| Connects to Claude via MCP | Yes — https://mcp.getsliq.com/mcp |
Yes — native MCP |
| Channels | LinkedIn and email | LinkedIn-first (email via Instantly / Smartlead integrations) |
| What happens on "go" | Drafts and queues; you approve before each send | Launches and runs the LinkedIn campaign automatically |
| Human approval gate | Yes — on every message, set per action type | No per-message gate; built to run autonomously |
| Best for | Running outbound from Claude while keeping the send button | Scaling automated LinkedIn campaigns across senders |
The takeaway: HeyReach's Claude integration is LinkedIn automation that executes once launched. Sliq's is LinkedIn and email, and every send is gated by your approval. Choose HeyReach if you want Claude to kick off a campaign that runs itself; choose Sliq if you want Claude to run your outbound and you to sign off on what actually goes out.

Why the approval gate matters when Claude runs your outbound
Handing outbound to an AI in a chat window is powerful and a little dangerous: a single prompt could, in theory, send hundreds of messages under your name. Sliq's gate removes that risk. Claude can do everything up to the send — find, research, personalize, draft — and then each message waits for you.
You also control how tight the gate is, action type by action type. Routine mechanics like profile follows and bare connection requests can auto-send; the messages that carry your voice — connection notes, first DMs, follow-ups, comments, and emails — stay on ask-me-first. So "run my LinkedIn outbound from Claude" doesn't mean "let Claude send whatever it wants." It means Claude drives and you approve. For the deeper argument, see the AI outbound tools that approve every message before it sends.
