Quibbly LinkedIn MCP server

---

The Quibbly LinkedIn MCP server connects your LinkedIn inbox to Claude and any other MCP client. Claude can read your conversations and connections, see who watched your videos, pull your CRM in beside them, and write messages that wait in Quibbly for you to send.

It is a hosted server, so there is nothing to install or run. You add one URL to your assistant and approve it once:

https://server.quibbly.co/mcp

Setup from sign-up to the first prompt, then four real examples: first messages to new connections, call prep with HubSpot, a follow-up with the right video attached, and syncing LinkedIn DMs into HubSpot.

See it work

One prompt in Claude, and a first message for every new BDR manager lands in the Quibbly sheet on LinkedIn, each with its own Send button. Nothing is sent until you click it.

What you can do

Write first messages to new connections

Write a first message to every BDR manager I connected with this month.

Claude searches your connections, skips anyone you have already messaged, and writes each person a message based on their role and company. Ask it to attach your intro video and every draft carries it.

Prep a call with your CRM beside the conversation

Prep me for my call with Marcus at Brightloop. Use HubSpot and my LinkedIn.

With HubSpot or Salesforce connected too, Claude pulls the deal, reads the whole LinkedIn conversation and checks who watched your videos: the part your CRM never had.

Write the follow-up, with the right video

Write my follow-up to Marcus. Answer his Sales Navigator question and attach my video that shows Sales Navigator.

Claude searches what you say inside your videos, not just their titles, attaches the right one, and drafts the reply beside the conversation on LinkedIn.

Sync your LinkedIn DMs into HubSpot or Salesforce

Sync my LinkedIn DMs into HubSpot.

Claude finds every message that isn't logged yet, matches each person to their CRM contact, creates the missing ones and logs each conversation. Quibbly remembers every match and where it stopped, so the next sync only moves what is new.

How it works

Claude never logs into LinkedIn. The Quibbly extension keeps a private, synced copy of your inbox while you use LinkedIn. Claude reads that copy through the MCP, and anything it writes goes back as a draft into the Quibbly sheet, right next to the conversation, where you send it yourself.

Quick start

About five minutes, start to finish.

1. Start Quibbly. Sign up at quibbly.co and pick Solo Pro, the plan with assistant access. The first 3 days are free; a card is needed to start, and if you cancel before the trial ends you pay nothing.
2. Add Quibbly to Chrome from the Chrome Web Store, in the Chrome profile you use for LinkedIn.
3. Turn on Inbox. Open LinkedIn, click the Quibbly tab on the left edge to open the sheet, and click Turn on Inbox. Your conversations start syncing.
4. Connect your assistant with the server URL below, then approve the connection on the Quibbly page that opens.

Connect your assistant

Claude (web, desktop and mobile)

1. Open Customize → Connectors, click + Add and choose Add custom connector.
2. Name it Quibbly and paste https://server.quibbly.co/mcp, then Add and Connect.
3. Sign in to Quibbly if asked, review the permissions and click Allow.

Connectors you add on claude.ai also work in the Claude desktop and phone apps.

Claude Code

claude mcp add --transport http quibbly https://server.quibbly.co/mcp

Then run /mcp in Claude Code and choose Quibbly to sign in.

Cursor

Add it in Settings → MCP → Add new server (transport HTTP), or put this in .cursor/mcp.json:

{
  "mcpServers": {
    "quibbly": {
      "url": "https://server.quibbly.co/mcp"
    }
  }
}

VS Code

.vscode/mcp.json:

{
  "servers": {
    "quibbly": {
      "type": "http",
      "url": "https://server.quibbly.co/mcp"
    }
  }
}

ChatGPT

On chatgpt.com, open Plugins, click + and choose Add custom MCP server. Paste https://server.quibbly.co/mcp, choose OAuth, create and install it, then approve on the Quibbly page that opens. ChatGPT allows custom MCP servers that write (Quibbly writes drafts) on Business and Enterprise plans; on Business, a workspace admin adds it.

Any other MCP client

Any client that supports remote MCP servers over streamable HTTP with OAuth can connect to https://server.quibbly.co/mcp.

If your client can't do the sign-in step, create a personal access token in Quibbly under Settings → Assistants and send it as Authorization: Bearer <token>. For clients that only speak stdio, a bridge such as mcp-remote works:

{
  "mcpServers": {
    "quibbly": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://server.quibbly.co/mcp"]
    }
  }
}

Tools

Claude picks the tools for you, so you never call them by name. 31 tools, in three permission scopes you approve when you connect:

• inbox:read: your synced conversations, connections, follow-ups, tags and drafts
• engagement:read: your videos and voice notes, and who watched them
• crm:write: propose replies and organise (drafts, follow-ups, notes, tags, CRM links). Nothing in this scope sends.

Tool	What it does
list_conversations	Synced conversations, newest first. Filter by status (waiting on you, waiting on them, follow-up due, hot, gone quiet, not interested, closed), tag, company or date.
search_messages	Full-text search across synced messages and contacts: names, headlines and companies.
read_conversation	One thread: messages, voice-note transcripts, the videos you sent and whether they were watched, follow-ups, the pending draft and your notes.
get_contact	One person: profile, CRM links, tags, notes, follow-ups and every video you sent them. On team plans, whether a teammate is already in touch.
recent_messages	A feed of messages across the inbox. Can return only what is new since the last sync to a CRM.
list_connections	Your connections, newest first, including people you have never messaged. Filter by date, words in the headline or company, and whether you have messaged them.
list_follow_ups	Follow-up reminders: overdue, due today, due this week, or all open.
list_tags	Your tags.
sync_status	How fresh the data is, whether the extension is online and whether Inbox sync is on.

Tool	What it does
who_watched	Who watched one video or your whole library: watch percent, watch time, plays and whether they replied.
list_library	Your videos and voice notes. Search covers names and what you say in each video.
get_library_item	One video or voice note in full: transcript, share link and everyone you sent it to.
find_attachments	Everything a draft can carry: videos, voice notes, snippet files, and files from your LinkedIn conversations.
list_quick_replies	Your saved snippets and their placeholders.

Tool	What it does
draft_reply	Proposes one message: a reply, or a first message to a connection. Text, an attachment, or both. It waits in your Quibbly drafts until you send it. Nothing is sent by this tool.
withdraw_draft	Removes a draft before anyone sends it.
list_drafts	Drafts and what happened to each: ready, sent, skipped, expired or failed.
upload_attachment	Stores a file (up to 8 MB) for 24 hours so a draft can carry it.

Tool	What it does
set_follow_up	Creates or moves a follow-up reminder.

save_script	Creates or edits one of your personal teleprompter scripts.

Tool	What it does

request_sync	Asks your extension to refresh your inbox now, if a LinkedIn tab is open.

Safe for your LinkedIn account

LinkedIn doesn't allow automation, so Quibbly is built so that nothing automated ever runs on your account:

• No bots, no auto-sending, no auto-connecting. None of the 31 tools can send a message, a connection request or a post.
• You click Send on every message, exactly as if you had typed it. Each draft has its own Send button; there is no send-all.
• Claude never touches LinkedIn. It reads the copy your extension already synced. The extension syncs gently in the background and backs off the moment LinkedIn asks it to.
• You stay in control. Every request an assistant makes is listed in Quibbly under Settings → Assistants, where you can disconnect any assistant or revoke all access at once. Reads and writes are rate limited per connection.

Pricing

The LinkedIn MCP is included in Solo Pro ($39 a month) and every team plan. Every plan starts with a 3 day free trial; a card is needed to start, and if you cancel before the trial ends you pay nothing. See all plans.
