Full LinkedIn platform management from your terminal. 43 platform commands (profiles, posts, messaging, connections, search, feed, engagement) **plus an OSINT suite**: company discovery, employee scraping, username generation, role classification, org charts, and email deanonymization — powered by cookie session auth.

Works as a **CLI** and an **MCP server** (for Claude Code, Cursor, Windsurf, and other AI agents). All 56 tools (43 platform + 13 OSINT) are exposed over MCP automatically, plus an interactive console for humans.

## OSINT Suite

The `osint` command group ports the best of three legacy Python toolkits
(`legacy/python/`) into the TypeScript engine — API-native, no browser needed:

| Command | What it does | Ported from |
|---------|--------------|-------------|
| `osint discover` | Discover companies by region (`--geo`), keyword, industry | osint_discover.py |
| `osint employees` | Scrape a company's employees (50/page; `--keywords` / `--geoblast` outer loops bypass the 1,000-result cap; detects the commercial-search UPSELL_LIMIT) | linkedin2username |
| `osint names` | Username/email permutations (`flast`, `f.last`, `firstl`, `first.last`, `first`, `lastf`) from a name or employees file | linkedin2username NameMutator |
| `osint classify` | Classify titles into 12 hierarchy levels x 20 divisions (rules engine learned from ~30K profiles) | osint_classify_rules.py |
| `osint ai-score` / `osint ai-classify` | Groq LLM relevance scoring / batch classification (graceful no-op without `GROQ_API_KEY`) | osint_classify_ai.py |
| `osint orgchart` | Build hierarchical org chart JSON (divisions x levels) | osint_build_orgchart.py |
| `osint matrix` | Standalone HTML matrix org chart (search, expand/collapse, avatars) | osint_generate_html.py |
| `osint stats` / `osint scan` | Classification health + suggested `title_overrides` for the rules JSON | osint_stats.py / osint_scan.py |
| `osint deep-dive` | One profile's about/experience/education/skills via the profileView endpoint, optional AI deep classification | osint_scrape_profiles.py |
| `osint email-lookup` | Email → LinkedIn profile via Outlook/Delve (needs a Microsoft token) | outlook_http_client.py |
| `osint funnel` | The full pipeline: discover → employees → orgchart → matrix, with resume | osint_funnel.py |

Offline-safe (no cookies needed): `classify --title`, `names --name`, `matrix`, `stats`, `scan`.
Everything else uses the same cookie session as the platform commands.

```bash
# Discover cybersecurity companies in the USA
linkedin osint discover --geo USA --keyword cybersecurity --limit 10

# Scrape their employees (and generate username lists for a domain)
linkedin osint employees acme-corp --keywords "sales,engineering" --domain acme.com

# Classify one title offline
linkedin osint classify --title "Senior Cyber Security Manager"

# Full funnel: discover -> employees -> org chart -> HTML matrix
linkedin osint funnel --geo USA --keyword fintech --limit 5

# Explore the result interactively
# (open assets/org_chart_viewer.html and load output/org_chart_*.json)
```

The interactive org chart viewer ships at `assets/org_chart_viewer.html` (tree + matrix modes, demo data in `assets/demo_org_chart.json`).


## Install

From source (this repo is not published to npm):

```bash
git clone https://github.com/gnmike57/linkedin-osint-cli.git
cd linkedin-osint-cli
npm ci
npm run build
npm link          # puts the `linkedin` command on your PATH

linkedin --help
```

`@inquirer/prompts` is an **optional** dependency: the interactive console uses
it when present and otherwise falls back to a built-in `node:readline`
implementation, so a restricted registry or a partial install never blocks you.
Force either path with `LINKEDIN_PROMPTS=inquirer` (require it, fail loudly) or
`LINKEDIN_PROMPTS=fallback` (always use the built-in console).

> **Note:** The npm package is `@bcharleson/linkedincli` but the CLI command is just **`linkedin`**.

## Local harness only

A **live LinkedIn session** (cookies, Chrome cookie import, Voyager API calls) must run on a **local harness only** — your own computer, such as a laptop or Mac mini.

Do **not** run a live session from Grok Bot, a cloud VM, or any remote runner. Safe use from those environments is limited to:

- installing the `linkedin` CLI binary, or
- calling an MCP server that is already running on the local harness

Cookies and Voyager calls never leave the local machine. Do not put `li_at` / `JSESSIONID` in a cloud or Grok Bot environment.

The opt-in `--from-chrome` and `LINKEDIN_HTTP=curl-impersonate` paths are **local-only**: they read a Chrome profile and/or `curl_chrome123` on that same machine.

## Sessions keep getting killed?

Default Node `fetch` has a TLS/JA3 fingerprint that is not Chrome. LinkedIn often detects that and **invalidates `li_at` on the first Voyager call** (issue [#1](https://github.com/bcharleson/linkedincli/issues/1)). Manual `li_at` + `JSESSIONID` paste still works for some accounts, but is the fragile path.

Two **opt-in, local-only** workarounds (default transport remains Node `fetch`):

1. **`LINKEDIN_HTTP=curl-impersonate`** — on the local harness, shell out to `curl_chrome123` so the TLS ClientHello matches Chrome.
2. **`--from-chrome` / `LINKEDIN_FROM_CHROME=1`** — on the local harness, read the full `linkedin.com` cookie jar from a local Chrome profile (not just the two auth tokens).

Use them together on the local machine when possible.

### Diagnostics

Set `LINKEDIN_DEBUG=1` to trace the HTTP transport on stderr (method, URL, status
and `Location` for each request, including redirects). It never logs cookies or
request bodies.

```bash
LINKEDIN_DEBUG=1 linkedin status --verify
```

### Install curl-impersonate (local harness)

Install `curl_chrome123` on the same local machine that holds the LinkedIn session. The transport looks for it on `PATH` (override with `LINKEDIN_CURL_IMPERSONATE_BIN`).

```bash
# Nix
nix profile install nixpkgs#curl-impersonate-chrome

# Homebrew
brew install curl-impersonate

# Confirm the binary exists
curl_chrome123 --version
export LINKEDIN_HTTP=curl-impersonate
```

If the binary is named differently on your platform, point at it:

```bash
export LINKEDIN_CURL_IMPERSONATE_BIN=/usr/local/bin/curl_chrome123
export LINKEDIN_HTTP=curl-impersonate
```

## Quick Start

### Interactive console

Run `linkedin` with no arguments (or `linkedin menu` from anywhere) to open the
interactive console: a searchable command palette over every CLI command, a
category browser, guided prompts for each argument/option, and the equivalent
scriptable command line printed before each run so you can graduate to
scripts. Session actions (`login`, `status --verify`, `logout`) are built in.
On a pipe or CI (no TTY), bare `linkedin` prints plain help instead.

The palette uses `@inquirer/prompts` when it is installed. That package is an
**optional dependency**: if your registry blocks it (or the install is broken),
the console silently falls back to a built-in zero-dependency
`node:readline` implementation with the same behaviour — so the console always
launches. Both paths are exercised by `npm run smoke:menu` (build first), which
drives a full session through the palette and asserts the selected command
actually runs.

### Option A — Read cookies from Chrome (local macOS/Linux only)

If you are already logged into LinkedIn in Chrome **on this machine**, the CLI can decrypt cookies from the local profile. This sends the full cookie jar (not just `li_at` + `JSESSIONID`), which matches a real browser more closely. Local-only — do not point this at a remote Chrome profile or run it from a cloud agent.

```bash
# macOS will prompt to unlock Keychain ("Chrome Safe Storage") the first time.
# Requires the `sqlite3` CLI (preinstalled on macOS; `sudo apt install sqlite3` on Linux).
linkedin --from-chrome profile me --pretty

# Or persist the two auth tokens into ~/.linkedin-cli/config.json
linkedin login --from-chrome

# Non-default Chrome profile
linkedin --from-chrome --chrome-profile "Profile 1" status --verify
```

Environment equivalents: `LINKEDIN_FROM_CHROME=1`, `LINKEDIN_CHROME_PROFILE=Default`. Optional: `LINKEDIN_CHROME_USER_DATA_DIR` to point at a custom user-data directory (Chrome/Chromium).

Windows is not supported for `--from-chrome` (Chrome 127+ App-Bound Encryption).

Cookie values are never printed to stdout/stderr.

### Option B — Paste cookies manually

Open LinkedIn in your browser → DevTools (`F12`) → Application → Cookies → `linkedin.com`

Copy these two values:
- **`li_at`** — your session token (long string starting with `AQED...`)
- **`JSESSIONID`** — your session ID (starts with `ajax:`)

```bash
linkedin login
# Paste your li_at and JSESSIONID when prompted
```

Or non-interactively:

```bash
linkedin login --li-at "AQEDxxxxxxx" --jsessionid "ajax:1234567890"
```

Manual paste + default Node fetch may still get the session killed. Prefer Option A plus `LINKEDIN_HTTP=curl-impersonate` on the local harness.

## Global Options

Every command supports these flags:

| Flag | Description |
|------|-------------|
| `--li-at <cookie>` | Override li_at cookie |
| `--jsessionid <cookie>` | Override JSESSIONID cookie |
| `--from-chrome` | Read cookies from a Chrome profile on this local machine |
| `--chrome-profile <name>` | Chrome profile directory (default: `Default`) |
| `--output pretty` | Pretty-printed JSON |
| `--pretty` | Shorthand for `--output pretty` |
| `--quiet` | No output, exit codes only |
| `--fields <list>` | Comma-separated fields to include |

## Environment Variables

```bash
export LINKEDIN_LI_AT="your_li_at_cookie"
export LINKEDIN_JSESSIONID="your_jsessionid_cookie"

# Opt-in: avoid Node fetch TLS fingerprint (requires curl_chrome123)
export LINKEDIN_HTTP=curl-impersonate
# export LINKEDIN_CURL_IMPERSONATE_BIN=/path/to/curl_chrome123

# Opt-in: read the full LinkedIn cookie jar from Chrome
export LINKEDIN_FROM_CHROME=1
# export LINKEDIN_CHROME_PROFILE="Profile 1"
```

Auth resolution order: `--from-chrome` / `LINKEDIN_FROM_CHROME` → `--li-at`/`--jsessionid` flags → env vars → `~/.linkedin-cli/config.json`

`linkedin status --verify` now classifies LinkedIn 3xx login/challenge redirects as `session_valid: false` with an auth message instead of a generic network error.

## MCP Server (AI Agents)

All 56 tools (43 platform + 13 OSINT) are available as MCP tools. The MCP process that talks to LinkedIn must run on the **local harness**. Cloud agents and Grok Bot may install the CLI binary or call this local MCP — they must not hold cookies or originate Voyager calls.

### Local Claude Code / Cursor / Windsurf

Add to the MCP config **on the local machine**:

```json
{
  "mcpServers": {
    "linkedin": {
      "command": "linkedin",
      "args": ["mcp"],
      "env": {
        "LINKEDIN_LI_AT": "your_li_at_cookie",
        "LINKEDIN_JSESSIONID": "your_jsessionid_cookie",
        "LINKEDIN_HTTP": "curl-impersonate"
      }
    }
  }
}
```

Or point straight at the standalone MCP entry (`dist/mcp.js`, no CLI wrapper):

```json
{
  "mcpServers": {
    "linkedin": {
      "command": "node",
      "args": ["/absolute/path/to/linkedin-osint-cli/dist/mcp.js"]
    }
  }
}
```

Then a **local** AI agent can manage LinkedIn through that MCP process. Remote/cloud agents should call this local server rather than starting their own session.

## Cookie Expiration

LinkedIn `li_at` cookies expire periodically (usually every few weeks). They can also be invalidated immediately when the client TLS fingerprint does not look like Chrome. When your session expires:

```bash
linkedin status --verify    # Check if session is valid
linkedin login --from-chrome
# or: linkedin login
```

## Search posts limitation

`linkedin search posts` is **not available**. LinkedIn's CONTENT resultType on `voyagerSearchDashClusters.b0928897b71bd00a5a7291755dcd64f0` still returns HTTP 200 but `included[]` is only a `FeedbackCard` (issue [#2](https://github.com/bcharleson/linkedincli/issues/2)). People and company search on the same queryId still work. A replacement content-search `queryId` has not been verified from public/in-repo sources, so this CLI does not invent one.

For posts **by a specific member**, use `profile posts` (`identity/profileUpdatesV2`):

```bash
linkedin profile posts <urn-id> --limit 20
```

## Development

```bash
npm run typecheck      # tsc --noEmit
npm test               # vitest
npm run build          # tsup -> dist/ (index.js + mcp.js)
npm run smoke:menu     # end-to-end interactive console (run build first)
npm run smoke:mcp      # MCP handshake + tools/list (run build first)
```

The smoke scripts drive the real `dist/` artifacts, not mocks: `smoke:menu`
runs two scripted console sessions (search path and category-browse path) and
asserts the selected command actually executes, that no prompt hangs on piped
input, and that the process exits cleanly; `smoke:mcp` boots the server,
performs the initialize handshake and verifies every tool is exposed with a
schema. Both force `LINKEDIN_PROMPTS=fallback` so scripted input behaves the
same on every machine. CI runs typecheck + tests + build + both smoke suites
on Node 18, 20 and 22 (plus Windows on Node 20).
