Why this one

Agents are fast. LinkedIn punishes fast.

01

The whole surface, not just sending

Reading, researching, commenting, publishing, listening and messaging. Most tools only do outreach, so everything else stays manual.

02

No browser automation

No Playwright loops, no selectors that break when LinkedIn ships a redesign. Real endpoints returning structured results your agent can use.

03

Your laptop can be closed

Schedule work from Claude and it runs in our cloud when it's due. Tuesday's post goes out Tuesday whether or not your agent is open.

04

Safety limits your agent can't skip

Daily caps, human-like pacing, working hours, and a breaker that halts writes the moment LinkedIn flinches. Your agent can't loop itself into a ban.

05

LinkedIn and X in one connection

Same tools, same agent, both platforms. Most MCP servers only do LinkedIn, so your agent needs a second integration for X.

06

It remembers the context

Who replied, who accepted, what was said last, where the lead came from. Your agent gets the history instead of starting cold every prompt.

FAQ

Questions, answered plainly

What can my agent actually do?

+
Broadly, anything you'd do yourself on linkedin.com. It can search and monitor posts, pull the people who commented or reacted, read profiles and companies, score leads against your ICP, comment and reply, react, publish posts and carousels, send invites and DMs, read your inbox, and watch for replies. Reading and listening are first-class, not just sending — so you can point it at research or content work, not only outreach.

What is MCP, in plain terms?

+
MCP is a standard that lets an AI assistant use outside tools. You connect Commentify once, and from then on Claude or Cursor can actually do things on LinkedIn and X instead of just writing you a plan you have to execute yourself.

Which AI clients does it work with?

+
Anything that speaks MCP: Claude and Claude Code, Cursor, Codex, ChatGPT, n8n, and your own agents. It's a remote MCP server, so there's nothing to install locally.

Do I need to keep my agent or laptop open?

+
No. Anything you schedule runs in our cloud when it's due, with your working hours and pacing rules still applied. Ask for a post on Tuesday morning or a follow-up next week and it happens, whether or not Claude is running.

Is my LinkedIn account safe?

+
This is where most agent setups go wrong, so the limits sit below the tools rather than in your prompt. Every account gets a sticky residential proxy, human-like pacing, daily caps, working hours, and a breaker that freezes writes the instant LinkedIn signals a checkpoint. Your agent cannot exceed those caps even if you tell it to. No automation is risk-free, but an agent can't blast 500 invites here.

Do I need Sales Navigator?

+
No. It works with or without. Sales Navigator gives you stronger search filters if you already pay for it, but you can build good lists from post commenters, reactors, profile viewers and keyword monitoring on a normal account.

How is this different from Lemlist, Waalaxy, HeyReach or Expandi?

+
Those are sequencers, and they only really do outreach: you build a campaign from templates and fixed steps and it runs the same way for everyone in the list. Here your agent keeps the reasoning and the context about your business, and gets the whole platform — research, content, commenting, listening and messaging — rather than a sending pipeline.

Does it really cover X as well as LinkedIn?

+
Yes — search, read threads, reply, post, follow, DMs and mention alerts, through the same connection and the same agent. That's the main thing other LinkedIn MCP servers don't do.

Is there a REST API if I'd rather not use MCP?

+
Yes. Same capabilities, same safety limits, plain REST with signed webhooks — for teams embedding this in their own product rather than driving it from a chat client. Mention it on the call.

What does it cost?

+
Priced per connected account, quoted on the call against your volume. Early users get pricing locked before it goes public.
