Your AI assistantExample

How did my campaigns do this week?

hollerly · list_campaigns

Two campaigns ran this week.

Q4 founders: 96 invites, 41 accepted, 9 replies, 2 meetings.
Agency owners: 88 invites, 30 accepted, 6 replies.

Q4 founders has the better reply rate. Want me to list the interested replies?

Yes, and pause Agency owners for now.

Run LinkedIn outreach by asking

No dashboards to click through. Type what you want in the chat you already use. Your assistant picks the right Hollerly tool, reads the answer and tells you what happened.

“How did my campaigns do this week?”

Invites, accepts, replies and meetings for every campaign, with the rates worked out for you.

list_campaigns

“Add these 20 founders to my Q4 campaign.”

Paste names and LinkedIn URLs, or a list from another tool. Duplicates and do-not-contact leads are skipped.

add_leads

“Which leads replied and are interested?”

Recent LinkedIn and email replies with each lead's name, company and pipeline stage.

list_replies

“Pause the agency campaign.”

Sending stops right away. No more invites, messages or emails until you resume it.

pause_campaign

“Move Dana from Brightline to meeting booked.”

The lead moves on your pipeline board, the same as dragging the card in Hollerly.

set_lead_stage

“Pull up everything on the lead who replied this morning.”

Profile, status, stage, reply tag, tags and timestamps for that one person.

get_lead

How to connect Claude to LinkedIn in 3 steps

Hollerly runs your LinkedIn and email campaigns in the cloud. The MCP server is the bridge between those campaigns and your AI assistant. Setup takes about a minute.

1
Start a Hollerly campaign

Connect your LinkedIn account, build a campaign and approve the first 5 sample messages. This is what the assistant will work with.
2
Add Hollerly as a connector

In Claude or ChatGPT, open Settings → Connectors → Add custom connector, and paste https://hollerlyai.com/api/mcp.
3
Sign in and click Allow

Log in to Hollerly when asked and approve access. Then open a new chat and ask how your campaigns are doing.

Claude and ChatGPT

The one-click way. You sign in to Hollerly in a browser window and approve access, so there is no key to copy or store. It works in claude.ai, the Claude desktop app and ChatGPT.

https://hollerlyai.com/api/mcp

Claude Code, Cursor and other dev tools

Create an API key in Settings → Integrations and send it as a header. The API docs have a JSON config for other clients.

claude mcp add --transport http hollerly \
  https://hollerlyai.com/api/mcp \
  --header "Authorization: Bearer hl_live_..."

Every tool in the LinkedIn automation MCP

Eight tools, kept short on purpose. Your assistant sees these and nothing else. There is no tool that writes or sends a message, and none that deletes data.

Tool	What it does	Type
list_campaigns	Lists your campaigns with lead, invite, accept, reply and meeting counts.	Read
get_campaign_stats	Stats for one campaign: the counts plus accept and reply rates.	Read
add_leads	Adds up to 500 leads to a campaign in one call. Each lead needs a LinkedIn URL or an email.	Write
list_replies	Recent replies on LinkedIn and email, with name, company and stage. Last 7 days by default.	Read
get_lead	One lead: profile, status, pipeline stage, reply tag, tags and timestamps.	Read
set_lead_stage	Moves a lead to replied, interested, meeting, proposal, won or lost.	Write
pause_campaign	Pauses a campaign. Nothing else goes out until it is resumed.	Write
resume_campaign	Resumes a paused campaign. Only works once 5 sample messages are approved in the app.	Write

ChatGPT LinkedIn automation, Claude and any MCP client

Use the assistant your team already pays for. Hollerly's AI still writes every message in your campaigns. The assistant you connect is the one you talk to.

Claude

claude.ai and the Claude desktop app. Add Hollerly as a custom connector and sign in.

ChatGPT

Add Hollerly as a connector in ChatGPT settings and sign in. Same tools, same rules.

Claude Code

One terminal command with your API key. Handy if you already live in the terminal.

Cursor

Add the server URL and API key header to your MCP config file.

Any MCP client

Hollerly speaks standard MCP over Streamable HTTP, so other clients work the same way.

An MCP server for LinkedIn outreach that keeps your rules

An AI assistant can be eager. Hollerly is not. Every request goes through the same checks as a click in the app, so a chat can never push your account past its limits. Read more about how Hollerly protects your LinkedIn account.

Safety caps still apply

Daily and weekly invite caps, message caps, warm-up and random gaps between actions stay in place.
Working hours only

Actions run in your working hours, and messages wait for the prospect's working hours too.
Your approval comes first

The assistant can't resume a campaign until you approve 5 sample messages in Hollerly. There is no way around it.
Do-not-contact is respected

Leads on your do-not-contact list, or already in your workspace, are skipped when added.
Revoke any time

Remove a connection or API key in Settings → Integrations and access ends straight away.

Built for teams that run a lot of campaigns

The MCP server is part of the Agency plan, alongside 3 LinkedIn accounts, 3 team seats and client reports. Agencies use it to check every client campaign from one chat. Founders use it as a lightweight AI SDR that reports back each morning. See the full list of Hollerly features or compare plans and pricing.

LinkedIn MCP server FAQ

What is an MCP server?

MCP (Model Context Protocol) is an open standard that lets AI assistants use outside tools. Hollerly's MCP server gives Claude, ChatGPT and other MCP clients a short list of actions on your Hollerly workspace, like reading campaign stats, adding leads and pausing a campaign, so you can run outreach by asking in plain words.

Does the LinkedIn MCP server send messages on its own?

No. There is no tool that writes or sends a message directly. Your assistant can add leads, read replies, move stages and pause or resume campaigns. Hollerly's own sequence does the sending, inside your daily caps and working hours, after you approve the first 5 sample messages.

Which plan includes the MCP server?

The MCP server comes with the Agency plan at $69 a month, together with the public API, 3 LinkedIn accounts and 3 team seats. Every plan starts with a 7-day free trial, and you are not charged if you cancel before day 8.

How do I connect Claude to LinkedIn with Hollerly?

In claude.ai or the Claude desktop app, open Settings, then Connectors, and add a custom connector with the URL hollerlyai.com/api/mcp. Sign in to Hollerly and click Allow. Claude then works with your Hollerly campaigns, which run your LinkedIn and email outreach.

Can I use ChatGPT for LinkedIn automation?

Yes. Add Hollerly as a connector in ChatGPT settings with the same URL, sign in and allow access. ChatGPT can then check results, add leads and pause campaigns. Depending on your ChatGPT plan, custom connectors may sit behind a developer mode setting.

Is it safe for my LinkedIn account?

The assistant goes through Hollerly, not around it. Every action keeps your daily invite and message caps, working hours, warm-up and do-not-contact list. Nothing is ban-proof, since LinkedIn does not allow third-party automation, but the MCP server adds no new way to exceed your limits.

How do I disconnect an assistant?

Open Settings, then Integrations in Hollerly. Revoke the connection or the API key there and the assistant loses access straight away. You can also remove the connector from Claude or ChatGPT, but revoking in Hollerly is the step that matters.
