Rack middleware to measure production code usage (LOC runtime usage)

https://github.com/0dayinc/pwn/README.md

rails-ai-context gives AI coding agents a complete mental model of your Rails app — not just files, but how schema, models, routes, controllers, views, and conventions connect. 39 live tools (via MCP server or CLI) let agents query structure on demand with semantic validation that catches cross-file errors (wrong columns, missing partials, broken routes) before code runs. Auto-generates context files for Claude Code, Cursor, GitHub Copilot, and OpenCode. Works standalone or in-Gemfile.

Unofficial Ruby SDK for interacting with Claude Code, supporting bidirectional conversations, custom tools, and hooks. Not officially maintained by Anthropic.

Provides an MCP (Model Context Protocol) server and a CLI to inspect SimpleCov coverage, including per-file summaries and uncovered lines.

FerrumMCP is a browser automation server that implements the Model Context Protocol (MCP), enabling AI assistants to interact with web pages through a standardized interface. Features include navigation, form interaction, content extraction, screenshot capture, JavaScript execution, cookie management, and advanced capabilities like smart cookie banner detection and AI-powered CAPTCHA solving.

A framework where markdown files with LLM-backed behavior act as first-class autonomous entities. Features inter-object communication and environment management.

Provides an MCP (Model Context Protocol) server and a CLI to inspect SimpleCov coverage, including per-file summaries and uncovered lines.

Model Context Protocol (MCP) server for Claude Code integration with Airbrake error tracking

A personal AI agent with desires, personality, and personal growth

An MCP server that provides access to BioRuby KEGG functionality, allowing AI assistants to query KEGG databases for biological pathways, compounds, and other molecular information.

An MCP server that indexes Cute Framework header files and provides search functionality for structs, functions, enums, and other elements.

MCP server and API for integrating Packwerk with AI tools like Cursor.

An MCP (Model Context Protocol) server that provides browser automation tools for AI agents using Ferrum and headless Chrome. Features 25 tools covering navigation, screenshots, form interaction, JavaScript evaluation, cookies, file downloads, and multi-session management.

This gem provides tools to manage Docker containers and images using MCP.

Developer tools for E11y: TUI, Browser Overlay, MCP Server

Evilution is a mutation testing tool for Ruby. It validates test suite quality by making small code changes and checking if tests catch them. AI-agent-first design with JSON output, diff-based targeting, and coverage-based filtering.

Agents that write and execute Ruby code. Inspired by smolagents. LLMs write executable code, not JSON blobs.

An MCP (Model Context Protocol) server that provides LLM agents with access to runtime context of executing Ruby processes. Connect to debug sessions, evaluate code, inspect objects, and control execution flow via MCP tools.

Agents that write and execute Ruby code. Developers can build and distribute Agents as files or compiled jar files. Inspired by smolagents. LLMs write executable code, not JSON blobs.
