Linkedin Cli

Post to LinkedIn using the official API v2. Uses OAuth tokens so only post when explicitly asked or scheduled.

Post to LinkedIn using the official API v2. This tool is rate-limited by LinkedIn, so only use it when the user explicitly asks you to post, or during scheduled cron tasks. Do not speculatively draft and post content.

Setup

1. Install (pinned to release tag):

bash

npm install -g github:0xmythril/linkedin-cli#v1.0.0

2. Create a LinkedIn app at https://www.linkedin.com/developers/apps
   • Enable Sign In with LinkedIn using OpenID Connect and Share on LinkedIn products
   • Add http://localhost:8585/callback to Authorized redirect URLs
3. Configure credentials (file is created with restricted permissions):

bash

mkdir -p ~/.config/linkedin-cli
touch ~/.config/linkedin-cli/.env
chmod 600 ~/.config/linkedin-cli/.env
cat > ~/.config/linkedin-cli/.env << 'EOF'
LINKEDIN_CLIENT_ID=your_client_id
LINKEDIN_CLIENT_SECRET=your_client_secret
EOF

4. Authenticate (opens browser for OAuth):

bash

linkedin-cli auth

5. Verify: linkedin-cli whoami

Security

• Credentials: Stored in ~/.config/linkedin-cli/.env (read by dotenv at runtime). Set chmod 600 to restrict access.
• No postinstall scripts: The package has zero install scripts — verify via npm pack --dry-run or inspect package.json.
• No telemetry or network calls except to the official LinkedIn API (api.linkedin.com) and OAuth (www.linkedin.com) when you run a command.
• Pinned install: The install command pins to a specific release tag. Audit the source at https://github.com/0xmythril/linkedin-cli before installing.
• Dependencies: Only 3 runtime deps — commander (CLI parsing), dotenv (env file loading), open (browser launch for OAuth). No transitive dependencies beyond these.

Important rules

• Do NOT post unless the user explicitly asks or a cron job triggers it. LinkedIn rate-limits API usage.
• Always confirm with the user before posting or sharing. Show them the text first.
• Keep posts professional — LinkedIn is a professional network.
• linkedin-cli accepts raw numeric IDs, full URNs, and LinkedIn post URLs.
• If you get a 401 error, the token has expired (~60 days). Ask the user to run linkedin-cli auth to re-authenticate.
• This tool is for posting only. It cannot read feeds, search profiles, or send messages.
