LinkedIn — Engagement via chrome-bridge MCP

LinkedIn is a React SPA on top of a logged-in Chrome session. The bridge profile has cookies. Do not attempt programmatic login. If redirected to /login or /checkpoint, stop and tell the user.

How this skill is laid out

Each capability has a focused JS file under scripts/. To use one:

1. Read the script file to load it as a string.
2. Pass the contents as the code argument to mcp__chrome-bridge__execute_script.
3. The script returns a structured object — see the header comment at the top of each file for the exact return shape.

Capability map

Profile overview via schema (fast path)

Before scrolling the activity feed, hit the profile page — LinkedIn embeds a JSON-LD array of the user's recent Pulse articles with headlines, publish dates, and like counts. Zero DOM scraping.

navigate(url='https://www.linkedin.com/in/<handle>/')
# wait ~5s
page_schema()
# → { schemas: [{ "@graph": [{ "@type": "Article", author, headline, datePublished,
#                              interactionStatistic: { userInteractionCount: 7139, ... },
#                              url }, ...] }] }

This is the cheapest way to enumerate a profile's recent article posts. It does not include feed-style short posts — for those, walk the activity page below.

View a profile's recent activity feed

navigate(url='https://www.linkedin.com/in/<handle>/recent-activity/all/')
# wait ~5s
execute_script(code=<contents of scripts/scroll_for_feed.js>)
# wait ~3s
posts = execute_script(code=<contents of scripts/enumerate_posts.js>)

Like a post

LinkedIn calls the like button the "Reaction button". Its aria-pressed reflects state.

result = execute_script(code=<contents of scripts/like_first_unliked.js>)
# wait ~1s, verify by re-querying the same button's aria-pressed

React with a specific emotion (not just Like)

execute_script(code=<contents of scripts/reaction_hover.js>)
# wait ~1s for picker to appear
dom_click('button[aria-label="Celebrate"]')   # or Like / Support / Love / Insightful / Funny

Comment on a post (ProseMirror)

LinkedIn's comment editor is ProseMirror. dom_fill will not work — you must use dom_type.

execute_script(code=<contents of scripts/comment_open.js>)
# wait ~2s for the editor to mount
dom_type('[role="textbox"][aria-label*="comment" i]', 'Great insight — thanks for sharing.')
# wait ~1s so LinkedIn's "empty comment" check unlatches
execute_script(code=<contents of scripts/comment_submit.js>)

Repost

execute_script(code=<contents of scripts/repost_open.js>)
# wait ~1s for the menu
execute_script(code=<contents of scripts/repost_select.js>)

Expand truncated post text

execute_script(code=<contents of scripts/expand_truncated.js>)

Dismiss banners and popups

LinkedIn throws occasional "Turn on notifications", "Upgrade to Premium", or messaging dropdowns over the feed:

execute_script(code=<contents of scripts/dismiss_banners.js>)

Rate limiting

• Likes: 3–5s between
• Comments: 10–30s between
• Follows / connects: 5–10s between
• Per session: 20–30 actions max, then pause 5–10 minutes

If you see "You've reached the weekly invitation limit" or "We've limited your activity", stop immediately.

Critical rules

1. Scroll before interacting. LinkedIn's feed lazy-loads — no posts exist in the DOM until scroll ~1000px down. Use scroll_for_feed.js.
2. Check aria-pressed before clicking Reaction. Clicking when already pressed will unlike. like_first_unliked.js does this for you.
3. Use dom_type for comments. Anything else silently fails.
4. Submit comments via comment_submit.js — it walks up from the editor to find the correct inner submit. The action-bar Comment button is a different element that re-opens the editor.
5. Skip Promoted / Suggested posts — [data-urn*="sponsored"] or look for "Promoted" in the card. Engaging with these wastes rate-limit budget.
6. Close tabs when done.

Example: like the 3 latest posts of a profile

navigate(url='https://www.linkedin.com/in/williamhgates/recent-activity/all/')
# wait ~5s
execute_script(code=<contents of scripts/scroll_for_feed.js>)
# wait ~3s

# Like the first 3 unliked posts in order
for _ in range(3):
    r = execute_script(code=<contents of scripts/like_first_unliked.js>)
    if r == 'all posts already liked': break
    # wait 4s (rate limit)
    execute_script(code=<contents of scripts/scroll_step.js>)
    # wait 2s
