@atom8n/mcp-logger

A Model Context Protocol (MCP) server that fetches logs from a local server running on localhost:6277. This package provides a simple interface to retrieve paginated log entries through the MCP protocol.

Overview

The mcp-logger is an MCP server implementation that acts as a bridge between MCP clients and a local logging service. It provides a single tool called get_logs that fetches log entries from http://localhost:6277/logs/current with support for pagination.

Features

• Log Retrieval: Fetch logs from a local server endpoint
• Pagination Support: Retrieve logs in pages with configurable limits
• Error Handling: Comprehensive error handling with descriptive messages
• MCP Protocol: Full compliance with Model Context Protocol standards
• TypeScript Support: Built with TypeScript for type safety

Installation

Global Installation

npm install -g @atom8n/mcp-logger

Local Installation

npm install @atom8n/mcp-logger

MCP Configuration

To use this MCP server with an MCP client, add the following configuration to your MCP client settings:

{
  "mcpServers": {
    "mcp-logger": {
      "command": "npx",
      "args": [
        "@atom8n/mcp-logger"
      ]
    }
  }
}

Alternative Configuration (if installed globally)

{
  "mcpServers": {
    "mcp-logger": {
      "command": "mcp-logger"
    }
  }
}

Usage

Once configured, the MCP server provides the following tool:

get_logs

Fetches logs from the local server at http://localhost:6277/logs/current.

Parameters:

• page (optional, number): Page number for pagination (default: 1)
• limit (optional, number): Number of log entries per page (default: 50)

Example Usage:

// Fetch first page with default limit (50 entries)
await mcpClient.callTool("get_logs", {});

// Fetch second page with 25 entries per page
await mcpClient.callTool("get_logs", {
  page: 2,
  limit: 25
});

Prerequisites

• Local Server: A server must be running on localhost:6277 that provides logs at the /logs/current endpoint
• Node.js: Version 14 or higher
• MCP Client: A compatible MCP client to interact with the server

Error Handling

The server provides detailed error messages for common scenarios:

• Connection Refused: When the local server is not running
• HTTP Errors: When the server responds with error status codes
• Timeout Errors: When requests take longer than 10 seconds
• Network Issues: When no response is received
