CLI and MCP server for LinkedHelper automation.

This project is brought to you by Alexey Pelykh.

What It Does

lhremote lets AI assistants (Claude, etc.) control LinkedHelper through the Model Context Protocol. It can:

• App management — detect, launch, and quit LinkedHelper instances
• Account & instance control — list accounts, start/stop instances, check status
• Campaign automation — create, configure, start, stop, and monitor campaigns with full action-chain management
• People import — import LinkedIn profile URLs into campaign target lists
• Profile queries — look up and search cached LinkedIn profiles from the local database
• Messaging — send direct messages, InMails, and connection requests; query messaging history and check for replies
• LinkedIn engagement — visit profiles, endorse skills, follow/unfollow, like posts, comment, and react
• Feed & post intelligence — read the LinkedIn feed, search posts, get post details, engagement stats, and engager lists
• Profile enrichment — extract emails, phones, socials, and company data from LinkedIn profiles
• LinkedIn search — build search URLs, resolve entity IDs, and query reference data for search filters
• Budget & throttle monitoring — check daily action limits and LinkedIn throttling status
• Action discovery — list available LinkedHelper action types with configuration schemas

Quick Start

npm install -g lhremote        # or: npx lhremote --help
lhremote launch-app            # start LinkedHelper with remote debugging
lhremote list-accounts         # find your LinkedIn account ID
lhremote start-instance        # start an instance (auto-selects single account)
lhremote campaign-create --file my-campaign.yaml   # create a campaign
lhremote import-people-from-urls <campaignId> --urls "https://www.linkedin.com/in/..."
lhremote campaign-start <campaignId> --person-ids <id1,id2,...>
lhremote campaign-status <campaignId>              # monitor progress

Pacing: LinkedIn monitors automated activity. See the Rate Limiting guide for recommended settings.

Prerequisites

• Node.js >= 24
• LinkedHelper desktop application (requires a paid subscription)

Installation

npm install -g lhremote

Or run directly with npx:

npx lhremote --help

Usage with Claude Desktop

Add to your Claude Desktop configuration (claude_desktop_config.json):

{
    "mcpServers": {
        "lhremote": {
            "command": "npx",
            "args": ["lhremote", "mcp"]
        }
    }
}

Once configured, Claude can use all 68 tools directly. A typical workflow:

1. find-app — Detect a running LinkedHelper instance (or launch-app to start one)
2. list-accounts — See available LinkedIn accounts
3. start-instance — Start an instance for an account
4. describe-actions — Explore available action types
5. campaign-create — Create a campaign from YAML/JSON configuration
6. import-people-from-urls — Import target LinkedIn profiles into the campaign
7. campaign-start — Run the campaign
8. campaign-status / campaign-statistics — Monitor progress
9. query-messages / check-replies — Review messaging results

MCP Tools

Common Parameters

Most tools and CLI commands connect to LinkedHelper via the Chrome DevTools Protocol (CDP). In addition to the tool-specific parameters listed below, all CDP-connected tools accept:

Security warning: Enabling allowRemote permits CDP connections to remote hosts. CDP is an unsandboxed protocol that grants full control over the target browser — equivalent to remote code execution. Only enable this when the network path between your machine and the target host is fully secured (e.g., SSH tunnel, VPN, or trusted LAN).

App Management

find-app

Detect running LinkedHelper application instances and their CDP connection details.

No parameters.

launch-app

Launch the LinkedHelper application with remote debugging enabled.

quit-app

Quit the LinkedHelper application.

Account & Instance

list-accounts

List available LinkedHelper accounts. Returns account ID, LinkedIn ID, name, and email for each account.

start-instance

Start a LinkedHelper instance for a LinkedIn account.

stop-instance

Stop a running LinkedHelper instance.

check-status

Check LinkedHelper connection status, running instances, and database health.

Campaigns

campaign-list

Export campaign configuration as YAML or JSON.

campaign-update

Update a campaign's name and/or description.

campaign-delete

Delete (archive) a campaign.

campaign-erase

Permanently erase a campaign and all related data from the database. This is irreversible — unlike campaign-delete (which archives), this removes all campaign data permanently.

campaign-stop

Stop a running campaign.

campaign-status

Check campaign execution status and results.

campaign-statistics

Get per-action statistics for a campaign.

campaign-retry

Reset specified people for re-run in a campaign.

Campaign Actions

campaign-add-action

Add a new action to a campaign's action chain. Use describe-actions to explore available action types.

campaign-remove-action

Remove an action from a campaign's action chain.

campaign-update-action

Update an existing action's configuration in a campaign. Only provided fields are changed.

campaign-reorder-actions

Reorder actions in a campaign's action chain.

Remove people from a LinkedHelper collection.

import-people-from-collection

Import all people from a LinkedHelper collection into a campaign. Large sets are automatically chunked.

Profiles & Messaging

query-profile

Like and optionally comment on posts and articles by a LinkedIn profile via an ephemeral campaign. Deducts from the daily action budget.

message-person

Send a direct message to a 1st-degree LinkedIn connection via an ephemeral campaign. Deducts from the daily action budget.

send-invite

Send a LinkedIn connection request via an ephemeral campaign. Deducts from the daily action budget.

send-inmail

Send an InMail message to a LinkedIn member (no connection required) via an ephemeral campaign. Deducts from the daily action budget.

remove-connection

Remove a person from 1st-degree LinkedIn connections (unfriend) via an ephemeral campaign. Deducts from the daily action budget.

Feed & Posts

get-feed

Read the LinkedIn home feed. Returns structured post data with cursor-based pagination.

get-post

Get detailed data for a single LinkedIn post including its comment thread.

get-post-stats

Get engagement statistics for a LinkedIn post: reaction count (broken down by type), comment count, and share count.

comment-on-post

Post a comment on a LinkedIn post. Checks action budget before attempting.

react-to-post

React to a LinkedIn post with a specific reaction type.

react-to-comment

React to a specific LinkedIn comment with a specific reaction type. Use this for the organic-engagement pattern of acknowledging a reply (e.g., the post author replied to your comment) without extending the thread. Mirrors react-to-post semantics scoped to one comment via its URN (as returned by get-post's commentUrn field).

LinkedIn Search & Reference

build-linkedin-url

Build a LinkedIn URL for any supported source type. Supports SearchPage (basic search with faceted filters), SNSearchPage (Sales Navigator), and parameterised templates for company, school, group, and event pages. CLI command: build-url.

resolve-linkedin-entity

Resolve human-readable names (company names, locations, schools) to LinkedIn entity IDs via LinkedIn's public typeahead endpoint. No authentication and no running LinkedHelper instance required. CLI command: resolve-entity.

list-linkedin-reference-data

List LinkedIn reference data for finite enumerations (industries, seniority levels, functions, company sizes, connection degrees, profile languages). Use this to discover valid IDs for search filters. CLI command: list-reference-data.

Utilities

List available LinkedHelper action types with descriptions and configuration schemas.

get-errors

Query current LinkedHelper UI errors, dialogs, and blocking popups.

dismiss-errors

get-action-budget

Get daily action budget showing limit types, thresholds, and today's usage from LH campaigns and CDP-direct actions.

get-throttle-status

Check if LinkedIn is currently throttling the account.

Known Limitations

• Platform support: LinkedHelper runs on macOS, Windows, and Linux. Binary paths are detected automatically but can be overridden with the LINKEDHELPER_PATH environment variable.
• Instance startup time: Starting an instance loads LinkedIn, which may take up to 45 seconds.
• Profile data is cached: query-profile and query-profiles search the local LinkedHelper database. Profiles must have been visited or imported by LinkedHelper to appear in results.
• Messaging scrape is slow: scrape-messaging-history navigates LinkedIn's messaging UI and can take several minutes depending on conversation volume.
• Same-machine requirement: lhremote must run on the same machine as LinkedHelper. CDP connections are localhost-only by default (for security), and database access requires direct file system access to the LinkedHelper SQLite database.

Troubleshooting

LinkedHelper is not running

Error: LinkedHelper is not running (no CDP endpoint at port 9222)

Solution: Use launch-app to start LinkedHelper, or start it manually. lhremote communicates with LinkedHelper via the Chrome DevTools Protocol (CDP), which requires the application to be running.

LinkedHelper is unreachable

Error: LinkedHelper processes detected but CDP endpoint is unreachable

Solution: LinkedHelper is running but its CDP port is not responding. This typically means a stale or zombie process. Use launch-app --force to kill stale processes and relaunch, or manually restart LinkedHelper.

Application binary not found

Error: LinkedHelper application binary not found. Set LINKEDHELPER_PATH to override.

Solution: Install LinkedHelper from linkedhelper.com. If installed in a non-standard location, set the LINKEDHELPER_PATH environment variable to the binary path.

No accounts found

Error: No accounts found.

Solution: Open LinkedHelper and configure at least one LinkedIn account before using lhremote.

Multiple accounts found

Error: Multiple accounts found. Specify accountId. Use list-accounts to see available accounts.

Solution: Use list-accounts to see available accounts, then pass the desired accountId to start-instance, stop-instance, or other tools.

No instance running

Error: No LinkedHelper instance is running. Use start-instance first.

Solution: Run start-instance before using campaign or messaging tools. An instance must be running to interact with LinkedIn.

Instance initialization timeout

Error: Instance started but failed to initialize within timeout.

Solution: The instance was started but took too long to finish loading. This can happen on slow connections. Try again; the instance may still be starting in the background. Use check-status to verify.

Database not found

Error: No database found for account

Solution: The LinkedHelper database file is missing for the specified account. Ensure the account has been used at least once in LinkedHelper so that a local database has been created.
