Text Saver MCP server

The TextSaver MCP is a server that integrates with Claude Desktop, allowing Claude to save text to files on your local filesystem. It provides a convenient way to preserve important information directly from your conversations with Claude.

Installation Requirements

• Python 3.8 or higher
• Claude Desktop application

Setup Instructions

Step 1: Install Dependencies

Install the required dependencies using pip:

pip install -r requirements.txt

Step 2: Configure Claude Desktop

Open your Claude Desktop configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: C:\Users\YourUsername\AppData\Roaming\Claude\claude_desktop_config.json

Add the TextSaver MCP server configuration:

{
  "mcpServers": {
    "text-saver": {
      "command": "/full/path/to/python",
      "args": [
        "/full/path/to/text_saver_mcp.py"
      ],
      "cwd": "/path/to/writable/directory",
      "host": "127.0.0.1",
      "port": 8080,
      "timeout": 30000
    }
  }
}

Important: Replace the paths with actual locations on your system:

• /full/path/to/python should be the path to your Python executable
• /full/path/to/text_saver_mcp.py should be the path to the script
• /path/to/writable/directory should be a directory where you want saved files to be stored

Step 3: Restart Claude Desktop

After configuring the MCP server, restart Claude Desktop for the changes to take effect.

Using TextSaver

After setup, you can ask Claude to save text in natural language. Here are some example prompts:

• "Save this text to a file"
• "Save this information to a file called notes.txt"
• "Write this content to a text file named project-ideas.txt"

The text will be saved to the directory you specified in the configuration.

Troubleshooting

Common Issues

Python Not Found Error

If you see "spawn python ENOENT" error, Claude can't find your Python executable. Find your Python path and use the full path in your configuration:

which python  # On macOS/Linux
where python  # On Windows

Read-only File System Error

This indicates the script doesn't have permission to write to the specified directory. Make sure the configured directory is writable.

Permission Problems

Ensure your save directory has appropriate write permissions:

chmod 755 /path/to/save/directory  # On macOS/Linux

Security Features

TextSaver includes several built-in security features:

• File size limits (default: 10MB)
• Filename validation and sanitization
• Protection against directory traversal attacks
• Writes only to the specified directory

For any other issues, check the logs in the Claude Desktop developer console.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "text-saver" '{"command":"/full/path/to/python","args":["/full/path/to/text_saver_mcp.py"],"cwd":"/path/to/writable/directory","host":"127.0.0.1","port":8080,"timeout":30000}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "text-saver": {
            "command": "/full/path/to/python",
            "args": [
                "/full/path/to/text_saver_mcp.py"
            ],
            "cwd": "/path/to/writable/directory",
            "host": "127.0.0.1",
            "port": 8080,
            "timeout": 30000
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

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

2. Add this to your configuration file:

{
    "mcpServers": {
        "text-saver": {
            "command": "/full/path/to/python",
            "args": [
                "/full/path/to/text_saver_mcp.py"
            ],
            "cwd": "/path/to/writable/directory",
            "host": "127.0.0.1",
            "port": 8080,
            "timeout": 30000
        }
    }
}
