Just_Facebook MCP Server

This project is a Model Context Protocol (MCP) server for automating and managing interactions on a Facebook Page using the Facebook Graph API. It provides tools to create posts, moderate comments, fetch post insights, and filter negative feedback — ready to plug into Claude or any other LLM-based agent.

Originally developed from @HagaiHen/facebook-mcp-server, this version is intended for packaging and distribution via PyPI.

🤖 What Is This?

This MCP provides a suite of AI-callable tools that connect directly to a Facebook Page, abstracting common API operations as LLM-friendly functions.

✅ Benefits

• Empowers social media managers to automate moderation and analytics.
• Seamlessly integrates with any Agent client.
• Enables fine-grained control over Facebook content from natural language.

🚀 Setup & Installation

1. Prerequisites

This project requires Python 3.10+ and uv (a fast Python package manager).

To install uv, run:

curl -LsSf https://astral.sh/uv/install.sh | sh

2. Clone the Repository

3. 🛠️ Install Dependencies

Use the uv tool with pyproject.toml:

# Install all dependencies and create a virtual environment
uv sync

# For development (includes testing and linting tools)
uv sync --dev

4. Set Up Environment

Create a .env file in the root directory and add your Facebook Page credentials:

FACEBOOK_ACCESS_TOKEN=your_facebook_page_access_token
FACEBOOK_PAGE_ID=your_page_id

Getting Your Facebook Credentials

1. Log into Facebook for Developers

2. Choose Developer as your use case.

3. Create a new app.

4. In the app dashboard, go to Customize Use Case and select all options.

5. Navigate to Tools → Graph API Explorer.

6. First create a User Access Token — make sure to:

   *Select all required permissions

   *Associate it with your app

7. Then generate a Page Access Token (this will inherit the permissions).

8. Save the Page Access Token and use it in the .env file.

To find your Page ID:

Go to your Facebook Page → About → Scroll down to view the ID

⏰ Important: Facebook API Token Limitations

Facebook access tokens have limited lifespans and will expire, causing API calls to fail. Understanding these limitations is crucial for maintaining your MCP server.

Token Types & Lifespans:

Token Type	Lifespan	Use Case
Short-lived User Token	1-2 hours	Testing only
Long-lived User Token	60 days	Development
Short-lived Page Token	1-2 hours	Testing only
Long-lived Page Token	60 days	Recommended for MCP
System User Token	No expiration*	Production apps

When Tokens Expire:

• ❌ All MCP tools will return OAuthException errors
• ❌ Error message: "Session has expired"
• ❌ Error codes: 190 (expired token) or 463 (session expired)

Automatic Token Refresh:

We provide a script to easily generate long-lived tokens (60 days):

uv run python scripts/refresh_facebook_token.py

This script will:

• ✅ Guide you through token generation
• ✅ Exchange short-lived for long-lived tokens
• ✅ Update your .env file automatically
• ✅ Validate the new token

Best Practices:

• 🔄 Refresh tokens every 50 days to avoid expiration
• 📅 Set calendar reminders for token renewal
• 🤖 Use long-lived Page tokens for development
• 🏢 Consider System User tokens for production

Troubleshooting Token Issues:

# Check if your token is expired
uv run python -c "
from just_facebook_mcp.manager import Manager
manager = Manager()
try:
    result = manager.get_page_fan_count()
    print('✅ Token is working')
except Exception as e:
    print(f'❌ Token error: {e}')
"

5. 🏃‍♂️ Running the Server

# Option 1: Using the script entry point (recommended)
uv run just_facebook_mcp

# Option 2: Run the Python module directly
uv run python -m just_facebook_mcp.server

# Option 3: Activate virtual environment first
source .venv/bin/activate
python -m just_facebook_mcp.server

🧩 Using with Claude Desktop

To integrate with Claude Desktop:

1. Open Claude Desktop

2. Go to Settings → Developer → Edit Config

Fast setup with uvx

You can use the MCP server without local installing with uvx:

Add the following to your MCP configuration:

{
  "mcpServers": {
    "just_facebook_mcp": {
      "command": "uvx",
      "args": [
        "just_facebook_mcp"
      ],
      "env": {
        "FACEBOOK_ACCESS_TOKEN": "<put_your_FB_token_here>",
        "FACEBOOK_PAGE_ID": "<put_your_page_id_here>"
      }
    }
  }
}

Development local setup:

If you already git-cloned the MCP server you can configure it locally.

Add the following to your MCP configuration:

Option 1: Using the package entry point (recommended)

{
  "mcpServers": {
    "just_facebook_mcp": {
      "command": "uv",
      "args": [
        "run",
        "--directory",
        "/absolute/path/to/just_facebook_mcp-server",
        "just_facebook_mcp"
      ]
    }
  }
}

Option 2: Using Python module

{
  "mcpServers": {
    "just_facebook_mcp": {
      "command": "uv",
      "args": [
        "run",
        "--directory",
        "/absolute/path/to/just_facebook_mcp-server",
        "python",
        "-m",
        "just_facebook_mcp.server"
      ]
    }
  }
}

Option 3: If installed via pip

{
  "mcpServers": {
    "just_facebook_mcp": {
      "command": "just_facebook_mcp"
    }
  }
}

Replace /absolute/path/to/just_facebook_mcp-server with your actual project path.
