LinkedIn for AI agents from your own Chrome session: search, profiles, lists, outreach queue.
Overview
A local MCP server that lets an assistant search, extract and act on LinkedIn through your own logged-in Chrome session, with caps and an approval queue.
- What you can do
- Search and extract profiles, search results, post engagers, group members, event attendees, company employees, connections and message threads, exported as CSV, JSON or SQLite. Organize contacts into named lists and CRM tags with dedupe, a contacted-before flag and intent signals. Run outreach sequences of visits, follows, invites, messages, InMail, likes and comments with branching and A/B variants. Read and triage the inbox with reply detection, sentiment tagging and saved replies. Build research packs from a CSV of names or domains into dossiers and enriched CSVs. Query the local SQLite mirror with read-only SQL.
- When to use it
- Useful when you want an AI assistant to do LinkedIn sourcing, list building, outreach drafting or inbox triage from your own account without a headless browser or cloud session. Also relevant if you want a free local alternative to paid prospecting tools.
- Requirements
- Runs locally via npx (Node.js). Needs Google Chrome with the toolkit's unpacked extension loaded in developer mode and paired with a token, plus a LinkedIn account you are signed into. LINKEDIN_TOOLKIT_HOME sets the directory for the local SQLite mirror and config, defaulting to ~/.linkedin-toolkit. Optional enrichment needs your own API key.
Installation
In SourceWeft
- Open LinkedIn Toolkit in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.
README
LinkedIn Toolkit
[License: MIT] [MCP] [No headless browser] [Runs locally] [CI]
LinkedIn blocks AI browser agents. This is how agents get in.
Operator, Browser Use, computer-use models and Playwright bots get challenged or banned on LinkedIn: headless fingerprints, datacenter IPs, machine-speed clicks. LinkedIn Toolkit gives any agent a safe, structured API to your own logged-in Chrome session — through the same internal endpoints the LinkedIn page itself calls, at human pace, under hard caps, with a human approval queue. It is also a free replacement for Waalaxy and PhantomBuster if you never touch an agent at all. No headless browser, no proxies, no cloud session, no telemetry, no subscription.
▶ Try it without installing · Install guide · Full-quality MP4
Recorded against the toolkit's own demo mode (lit serve --http --fake). Every tool call is real; everyone in it is invented.
Quick start
One command, then three clicks in Chrome.
That downloads the extension for your version, checks it, unpacks it to
~/.linkedin-toolkit/extension, prints the pairing token, waits for the extension to connect,
and writes the MCP config block into your client's own config file — keeping every other
server in it and backing the file up first. --client takes claude-desktop, claude-code,
cursor, windsurf, vscode, n8n or print; add --dry-run to see what it would do
without touching anything.
Then the three steps Chrome does not let any installer do for you:
- Open
chrome://extensions— type it in the address bar; it does not come up in search. - Turn on Developer mode, top right.
- Click Load unpacked and choose the folder setup printed.
Paste the pairing token into the popup → Settings → Local bridge, and check it took:
Rather do it by hand, or only want the extension and no agent?
Download linkedin-toolkit-extension-v*.zip from the
Releases page, unzip it
somewhere permanent (Chrome loads it from that folder on every start), then do the three steps
above. Run npx linkedin-toolkit-mcp for the pairing token, and copy the config block for your
client out of docs/clients.md.
docs/install.md is the same thing with screenshots, written for somebody who has never loaded an unpacked extension.
Mass unfollow — Preview first, then a small number, then the rest — is in docs/install.md. Read the "Connections are followed too" part before you decide the feature is broken: LinkedIn's Following list does not include your connections, who are followed automatically when you connect, so emptying that list to zero leaves a feed still full of posts. Ticking "Also unfollow my connections" scans your followers list instead, which is the only place that state is visible.
Every client's config file, path and shape: docs/clients.md · one page per ecosystem.
Not using MCP? lit serve --http gives you POST /actions/{action} and a generated
GET /openapi.json. Examples in seven languages.
[!IMPORTANT] Nothing sends without you. Copilot mode is the default: every write an agent makes queues for your approval in the popup. Hard caps live in the extension — 100 invites, 150 messages, 500 profile visits, 1,000 search results a day — and no agent, CLI flag or config file can raise them. Read the safety page before you turn Autopilot on.
What it does
Works with your agent
Structured errors carry code, message, retryAfter and howToFix, so an agent recovers or
explains itself instead of retrying into a wall. There is an
llms.txt and an agent quickstart written for an agent to
read and self-install.
Browser agents vs LinkedIn Toolkit
The long version, with the actual detection mechanisms: Why browser agents fail on LinkedIn.
Why extensions broke, and why this one is built to be repaired
LinkedIn's web client now serves nearly all of its data through
GET /voyager/api/graphql?queryId=<name>.<32-hex hash>&variables=(...), and those hashes change
with each web client release (current: 1.13.46474). The old REST Voyager paths that a generation of
2024–2025 extensions hard-coded return 400, 410 or 500 today. That is the mechanism — not a ban
wave. This extension calls the same GraphQL queries the page calls, from inside your own tab, and
keeps every query ID in one refreshable table with its capture date and client version:
docs/voyager-endpoints.md. lit endpoints check reports which are ok,
failed or unverified, and lit endpoints doctor names the query id whose hash went stale and the
key in the table that holds it, so drift is a maintenance task rather than an architecture change.
Honestly: those IDs will drift, and re-capturing them is the contribution this project most
needs. It is a table edit, not a rewrite — open DevTools on LinkedIn, filter the Network tab for
voyager/api, and copy the queryId from a request the page makes; the same hashes are also
literal strings inside LinkedIn's JS bundles if you would rather grep for them.
Versus the paid tools
Competitor prices are public list prices checked September 2026 and are approximate — they
change, vary by currency and billing term, and each vendor's tiers differ. Feature claims are taken
from each vendor's public product pages, also checked September 2026, and tiers move. Check their
sites before deciding anything. Corrections welcome via PR — if we have a feature wrong, open one
and it gets fixed.
Source for the Waalaxy column: its current Chrome extension listing, "Alien Copilot" by Waapi
(Montpellier) — v1.1.3, updated August 2026, roughly 2,000 users, 3.0★ from 3 ratings — which
describes itself as "your Waalaxy companion, helps you import prospects". On that listing the
extension imports prospects into Waalaxy, and the automation runs on Waalaxy's servers using your
session. Listing details read September 2026.
Research Pack
Drop in a CSV with any of name, linkedin_url, email, domain, company. Get back a dossier
per row, an enriched CSV, and a list — all local.
- Resolve — match each row to a profile or company. Ambiguous rows come back with candidates and a confidence score for you to pick from, rather than a silent guess.
- Gather — full profile capture, company page, recent posts and engagement, mutual connections, connection status.
- Signals — job change in the last 90 days, recent posting activity, hiring signals, headcount band, mutuals, engaged-with-me.
- Enrich (optional, your key, off by default) — verified email and phone.
- Web — the
linkedin-research-packskill has your agent use its own web search for news, talks, GitHub and podcasts, and write them into the pack with sources. The extension never crawls the open web. - Write —
pack.mdandpack.jsonper row, anoutput.csvwith every original column plus resolved URL, title, company, location, signals and match confidence, and a new list.
Caps apply throughout: resolution spends search quota, capture spends visit quota. A 500-row CSV is a multi-day job by design, and you get the ETA up front.
Safety
The honest position: LinkedIn's User Agreement prohibits automated access. This tool automates LinkedIn. Nothing below makes that risk zero.
What it does do:
- Hard caps in the extension, below every client: 100 invites, 150 messages, 500 profile
visits, 1,000 search results per day.
config.setclamps whatever you pass. - Human pacing — jittered 8–15 second delays, hourly caps, a business-hours window, weekdays only if you want. Machine-speed activity is the loudest signal an account can emit.
- 14-day warm-up for new or dormant accounts.
- Copilot mode — every agent write queues for your approval. Autopilot is a toggle only a human can flip, in the popup. Approving still is not sending: the engine paces it anyway.
- 429 → backoff. A security check → stop. A CAPTCHA or "confirm it's you" check — whether it arrives as a 451 or, as it usually does, as a redirect to LinkedIn's checkpoint page — pauses every request immediately and stays paused until you have completed it yourself and said so in the popup. There is no retry loop anywhere in the codebase.
- Never bypasses a security measure. No CAPTCHA solving, no challenge circumvention, no proxies, no fingerprint spoofing, no cookie import, no account you are not signed into. What triggers a check, what the toolkit does, what you should do and what we will not build: docs/captcha-and-security-checks.md.
What it does not do is make you invisible. Running inside your own session removes the fingerprint and IP signals that get browser agents caught — it does nothing about how much you do or how regularly you do it, and LinkedIn counts both. That is exactly why the caps and the pacing are not configurable past a ceiling: they are the only defence left once the easy tells are gone. An account sending 90 invites a day at perfectly spaced intervals is still an account sending 90 invites a day.

Architecture
One engine, several clients: the popup, the CLI, an MCP tool call and a campaign step all go
through the same handle(action, params, origin) switch. The caps and the queue sit below it, so
there is no path around them — there is only one path. Full architecture ·
action contract · tool reference.
CLI
lit ships in the same npm package as the server.
Full reference · shell examples.
Your data is a SQLite file
Everything you capture mirrors into ~/.linkedin-toolkit/toolkit.db. Agents get read-only SQL over
it — no network, no quota, no rate limit — and you can open the same file in any SQLite tool.
An agent reaches the same thing through linkedin_query_sql with { "sql": "SELECT …" }.
SELECT only — anything else is rejected.
Webhooks
The server POSTs { event, payload } to a URL you set — invite_accepted, reply_received,
positive_reply, campaign_step_done, campaign_completed, quota_hit, challenge_detected,
queue_item_added, queue_item_sent, campaign_note_truncated, research_progress,
research_completed.
An importable n8n workflow does the obvious thing with them: accepted invite →
profile.get → an LLM drafts a first message → it queues → Slack asks a human → approval link →
queue.approve.
Skills
Six task recipes in the Agent Skills format. They carry the guardrails — facts only, quota awareness, the approval queue as the expected destination — not just the tool sequence.

Contributing
Adding an extractor is the best first contribution and touches four files: how to build one. Sequences, skills and agent integrations are merged fastest because they are additive and self-contained.
