TL;DR

  • What is it? — This is an MCP server that automatically logs AI coding assistant activities such as command executions and code generation (supports Roo Code, Cline, Claude Code, etc.).
  • What does it do? — It saves activity history as JSON files, which you can search and analyze later.
  • How do I use it? — Add it to your Claude Code, Cline, or Roo-Code settings to enable automatic activity logging.

Overview

Roo Activity Logger is an MCP (Model Context Protocol) server that automatically records AI coding assistant development activities — including command executions, code generation, file operations, and more. It supports Claude Code, Cline, Roo-Code, and other MCP-compatible AI assistants. All logs are saved in JSON format, making it easy to search, analyze, and restore context at any time.

Sample Log Entry

Here is an example of a file_operation log entry saved as JSON:

{
  "id": "75add15d-8d5b-4e60-b327-fde785050c86",
  "timestamp": "2025-04-10T01:58:02.905Z",
  "type": "file_operation",
  "level": "info",
  "summary": "Inserted mermaid diagram into README.md",
  "details": {
    "file": "README.md",
    "operation": "insert_content",
    "insertedLines": "mermaid code block",
    "position": "after overview section"
  },
  "intention": "To visually explain the flow of saving and retrieving activities",
  "context": "Improving documentation for Roo Activity Logger",
  "parentId": "98280366-1de1-48e0-9914-b3a3409599b4"
}

Each log contains:

  • Log level (debug, info, warn, error)
  • Summary
  • Details (any structured data)
  • Intention / Purpose
  • Context information
  • Parent activity ID (for hierarchy)
  • Sequence number (for ordering)
  • Related activity IDs (for grouping)

Logs are:

  • Saved as date-based JSON files
  • Searchable by type, level, date, text, etc.
  • Customizable — you can specify different save directories per activity

Features

  • Logs various activity types:

    • Command executions (command_execution)
    • Code generation (code_generation)
    • File operations (file_operation)
    • Errors (error_encountered)
    • Decisions (decision_made)
    • Conversations (conversation)
  • Each activity log includes:

    • Unique ID
    • Timestamp
    • Activity type
    • Summary, details, intention, context, and optional metadata

Usage (Recommended: via npx)

You can run Roo Activity Logger directly without cloning the repository by using npx.

Add this to your Cline, Roo-Code, or Claude Code configuration:

{
  "mcpServers": {
    "roo-activity-logger": {
      "command": "npx",
      "args": ["-y", "github:annenpolka/roo-logger"],
      "env": {},
      "disabled": false
    }
  }
}

Then, add prompts to your rule files (for Cline/Roo-Code) or CLAUDE.md (for Claude Code) to ensure logging, for example:

## Important

Always log activities using roo-activity-logger according to the logging rules.

## Preparation

Check the current context with `git status`.

Then, use roo-activity-logger's `search_logs` to review existing logs and identify current tasks.

Be sure to perform the logging steps.

## Logging

- Always use roo-activity-logger for all logs
- Include stack traces and execution context
- Record intention and context

For Developers: Local Setup

To develop or customize locally, clone the repository and build:

# Clone the repo
git clone https://github.com/annenpolka/roo-logger.git
cd roo-logger

# Install dependencies
npm install

# Build
npm run build

Example configuration to use your local build:

{
  "mcpServers": {
    "roo-activity-logger": {
      "command": "node",
      "args": ["/path/to/your/local/roo-logger/dist/index.js"], // adjust path accordingly
      "env": {},
      "disabled": false
    }
  }
}

Notes

  • The specified directory will be created automatically if it does not exist.
