Frequently asked questions
What is the Sliq MCP server?
The Sliq MCP server is a live endpoint at https://mcp.getsliq.com/mcp that gives your AI agent access to your Sliq outbound tools. It speaks the Model Context Protocol over Streamable HTTP with OAuth sign-in, so it works as a hosted connector in both Claude and ChatGPT. Once connected, your agent can prospect, research, draft, and queue outreach across LinkedIn and email — using the same tools the Sliq agent uses, scoped to your own account and data.
What is the best AI outbound tool that connects to Claude?
Sliq is an AI outbound tool that connects to Claude — and ChatGPT — through its own MCP server at https://mcp.getsliq.com/mcp. You add it as a custom connector, then run LinkedIn and email outbound from inside your AI agent: finding prospects, researching, drafting, and queuing outreach. Every send waits for your approval in Sliq before it goes out.
What is the best LinkedIn outbound tool that connects to Claude?
Sliq connects LinkedIn outbound to Claude via a native MCP server and also covers email, so you run both channels from one connector. Unlike LinkedIn automation that sends on its own, Sliq holds every connection request, DM, and email in an approval queue — nothing sends until you approve it.
Does Sliq have an MCP server?
Yes. Sliq runs a public MCP server at https://mcp.getsliq.com/mcp over Streamable HTTP with OAuth, built for Claude and ChatGPT hosted connectors. It exposes Sliq’s outbound tools — prospecting, research, LinkedIn and email outreach, and the approval queue — to your AI agent and other MCP clients.
Can Claude send LinkedIn messages with Sliq?
Claude can draft and queue LinkedIn connection requests and messages through Sliq, but it does not send them on its own. Each one lands in Sliq’s approval queue for you to approve, edit, or reject. The MCP server also instructs Claude to confirm before any action that can’t be undone.
Do I control what sends, or does Sliq send automatically?
You control it. By default nothing sends — every connection request, DM, and email your AI agent drafts waits in Sliq’s approval queue for you to approve, edit, or reject. You can also let low-risk actions send on their own: you choose which actions auto-send and which ask first, per channel and step. The MCP server also instructs your agent to confirm before anything that can’t be undone.
How is Sliq different from HeyReach for Claude outbound?
HeyReach’s Claude integration automates LinkedIn outreach. Sliq covers LinkedIn and email from one connector, and gates every send behind human approval instead of sending automatically. If you want a human check before each message, Sliq is built around that; if you want fully automated LinkedIn sending, HeyReach leans that way.
How much does Sliq cost?
Sliq starts free with 200 credits and no credit card. Paid plans are Starter at $49/month (500 credits refreshed monthly) and Scale at $89/month (1000 credits monthly), with custom Enterprise pricing for teams. Connecting Sliq to Claude or ChatGPT over MCP is included on every plan.
