LinkedIn Post Creator for Claude

A Model Context Protocol (MCP) tool that allows Claude to create and schedule LinkedIn posts on your behalf.

Overview

This tool enables Claude to post content to LinkedIn directly through a simple API. It uses the Model Context Protocol (MCP) to integrate with Claude Desktop, allowing for a seamless experience when you want to draft and publish LinkedIn content with AI assistance.

Features:

• Create LinkedIn posts with custom content
• Schedule posts for future publication
• Secure handling of LinkedIn API credentials
• Debug mode for testing without posting to LinkedIn

Installation

Prerequisites

• Rust (1.76.0 or newer)
• Claude Desktop
• LinkedIn Developer Account with API access

Setup

1. Clone the repository:

   git clone https://github.com/yourusername/linkedin-mcp-server.git
   cd linkedin-mcp-server
   

2. Create an .env file with your LinkedIn credentials:

   LINKEDIN_ACCESS_TOKEN=your_access_token_here
   LINKEDIN_PERSON_ID=your_linkedin_person_id
   SERVER_ADDRESS=0.0.0.0:3500
   LOG_LEVEL=info
   DEBUG_MODE=true  # Set to false in production
   

3. Build the project:

   cargo build --release
   

Integrating with Claude Desktop

To use this tool with Claude Desktop, you need to create a wrapper script and update Claude's mcpServers.json file.

Step 1: Create a Wrapper Script

Create a file named run_linkedin_server.sh (Linux/macOS) or run_linkedin_server.bat (Windows):

For macOS/Linux:

#!/bin/bash

# Set environment variables explicitly
export LINKEDIN_ACCESS_TOKEN="your_access_token_here"
export LINKEDIN_PERSON_ID="your_linkedin_person_id"
export SERVER_ADDRESS="0.0.0.0:3500"
export LOG_LEVEL="info"
export DEBUG_MODE="true"  # Set to false when ready for real posting

# Change to the directory containing your Rust project
cd /ABSOLUTE/PATH/TO/YOUR/linkedin-mcp-server

# Run the project
cargo run --release

Make it executable:

chmod +x run_linkedin_server.sh

For Windows:

@echo off
rem Set environment variables explicitly
set LINKEDIN_ACCESS_TOKEN=your_access_token_here
set LINKEDIN_PERSON_ID=your_linkedin_person_id
set SERVER_ADDRESS=0.0.0.0:3500
set LOG_LEVEL=info
set DEBUG_MODE=true

cd /d C:\ABSOLUTE\PATH\TO\YOUR\linkedin-mcp-server
cargo run --release

Step 2: Configure Claude Desktop

1. Locate the mcpServers.json file:

   • On macOS: ~/Library/Application Support/Claude/mcpServers.json
   • On Windows: %APPDATA%\Claude\mcpServers.json
   • On Linux: ~/.config/Claude/mcpServers.json

2. Edit the file to add your LinkedIn tool:

{
    "mcpServers": {
        "linkedin_post": {
            "command": "/ABSOLUTE/PATH/TO/YOUR/run_linkedin_server.sh",
            "args": []
        }
    }
}

If you already have other tools in this file, add your LinkedIn tool as an additional entry.

3. Restart Claude Desktop

Using the Tool with Claude

Once configured, you can use the tool in conversations with Claude:

1. Start a new conversation in Claude Desktop

2. Ask Claude to help you create a LinkedIn post:

   Can you draft a LinkedIn post about our new product launch and post it for me?
   

3. Claude will draft the post and use the tool to publish it to LinkedIn

4. To schedule a post for the future, specify a time:

   Draft a LinkedIn post about our upcoming webinar and schedule it for next Monday at 9am.
   

Example Prompts

• "Create a LinkedIn post announcing our new partnership with Acme Corp."
• "Draft a professional LinkedIn update about my recent promotion to Director of Marketing."
• "Help me write a LinkedIn post about our industry conference and schedule it for Tuesday next week."
• "Create a LinkedIn post sharing our quarterly results."

Troubleshooting

Tool Not Available in Claude

• Make sure your server is configured correctly in mcpServers.json
• Check that the paths in your wrapper script are correct
• Restart Claude Desktop
• Look for error messages in Claude's console

Authentication Issues

• Verify your LinkedIn API credentials are correct
• Ensure your access token has the appropriate permissions
• Check that the environment variables are set correctly in your wrapper script

Port Conflicts

If you see an error like "Address already in use":

1. Change the port in your wrapper script and server configuration
2. Ensure no other instance of the server is running
3. Check if another application is using the same port

Development

Debug Mode

Set DEBUG_MODE=true in your environment variables to prevent actual posts to LinkedIn during testing.

Logging

Adjust the LOG_LEVEL environment variable to control logging verbosity:

• trace: Most detailed
• debug: Development information
• info: General information (default)
• warn: Warnings only
• error: Errors only
