Installation and Configuration

Method 1: Direct Use (Recommended)

Use emlog-mcp directly in Claude Desktop configuration without local installation. Jump to MCP Client Configuration section.

Method 2: Local Development Installation

1. Clone the Project

git clone https://github.com/eraincc/emlog-mcp.git
cd emlog-mcp

2. Install Dependencies

npm install

3. Environment Variable Configuration

Copy the example configuration file and edit:

cp .env.example .env

Set the following environment variables in the .env file:

# Emlog API base URL (required)
EMLOG_API_URL=https://your-emlog-site.com

# Emlog API key (required)
EMLOG_API_KEY=your_api_key_here

Getting API Key:

1. Log in to your Emlog backend management system
2. Go to "Settings" → "API Interface"
3. Enable API functionality and generate API key
4. Copy the generated key to the .env file

4. Build Project

npm run build

5. Run Service

npm start

Or development mode:

npm run dev

MCP Client Configuration

Claude Desktop Configuration

Add to Claude Desktop configuration file (usually located at ~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "emlog": {
      "command": "npx",
      "args": ["emlog-mcp"],
      "env": {
        "EMLOG_API_URL": "https://your-emlog-site.com",
        "EMLOG_API_KEY": "your_api_key_here"
      }
    }
  }
}

Note: The configuration now directly uses the published npm package emlog-mcp, no local installation or compilation required. npx will automatically download and run the latest version.

The project also provides an example configuration file claude-desktop-config.json for reference.

Other MCP Clients

For other MCP-supporting clients, please refer to their respective documentation for stdio transport configuration.

• Parameter Errors - Input parameter validation and prompts

Development and Debugging

Available Scripts

# Build project
npm run build

# Start service
npm start

# Development mode (auto restart)
npm run dev

# Watch mode (auto compile)
npm run watch

# Run tests
npm test

Log Output

The service outputs runtime status information to stderr for debugging:

Emlog MCP server running on stdio

Test Service

The project includes a simple test script test-server.js to verify if the service is working properly:

node test-server.js

Security Considerations

1. API Key Protection - Ensure API keys are not leaked, use environment variables for storage
2. HTTPS Connection - Recommend using HTTPS connection to Emlog API in production
3. Permission Control - Ensure API keys have appropriate permission scope
4. Input Validation - All user inputs are validated and sanitized

Troubleshooting

Common Issues

1. Connection Failure

   • Check if EMLOG_API_URL is correct
   • Confirm Emlog site is accessible

2. Authentication Failure

   • Verify if EMLOG_API_KEY is valid
   • Check API key permissions

3. Tool Call Failure

   • Check specific reasons in error messages
   • Confirm parameter format is correct
