Iris is a local-first MCP server that scores AI agent runs for quality, safety, and cost using 20 built-in deterministic rules, an optional LLM judge, and a web dashboard — all on your machine with no account or telemetry.

Persistent memory engine for AI coding agents. Auto-captures sessions via hooks, stores in SQLite with BM25/vector/graph hybrid search, and serves 54 MCP tools across 20+ agents. Self-hosted, keyless, zero external dependencies.

An MCP server for South Korean listed companies' ESG data, created by a securities analyst. It allows AI agents like Claude and ChatGPT to query ratings from 5 agencies, governance indicators, and GHG emissions from KRX, KIND, and GIR via 12 tools without requiring API keys.

Connect Blender to any LLM for AI-assisted 3D modeling, scene creation, and object manipulation via socket-based communication.

CoalLedger is a docs-health checking suite for AI coding agents — the documentation counterpart to CoalMine's code canaries. Seven canaries flag wrong, incomplete, stale, contradictory, broken, unreadable and (optionally) leaked documentation, with a bundled zero-dependency CommonMark+GFM AST engine, context-judged severity and choice-gated fixes.

ECC is an agent harness operating system that provides a coordinated engineering system and toolbox for AI agents, enabling structured workflows like planning, testing, and reviewing.

17-lesson tutorial teaching harness engineering for AI agents: build the tools, knowledge, permissions, and context management around an LLM agent loop, using Claude Code as the reference design. Runnable Python examples progress from the agent loop to a goal loop.

AI-powered template that clones any website into a clean Next.js app via a single command. Supports Claude Code, Cursor, Codex, Gemini, and more.

A local, read‑only dashboard that visualizes Claude Code usage—token counts, cost estimates, sessions, tools, skills, projects, and activity patterns—by scanning ~/.claude/projects/ and serving a FastAPI‑based UI.

OmniRoute is an open-source MIT-licensed AI gateway providing one unified endpoint to access 352+ AI providers and 1200+ models (150+ free tiers). It features quota-aware auto-fallback, token compression saving 15–95%, and integrates with Claude Code, Cursor, Cline, and other coding agents.

Oh My OpenAgent (OmO) is an open-source AI coding agent toolkit with three editions: Ultimate for OpenCode, Light for Codex CLI, and standalone Senpi beta. It provides multi-model orchestration, ultrawork mode, parallel team agents, LSP/AST-Grep integration, and MCP support to automate and streamline software development workflows.

Lemory is a local middleware that transforms markdown notes (e.g., Obsidian vaults) into a context database for AI agents. It supports keyless on-device hybrid search, Korean-specific processing, hierarchical token savings, and knowledge graph visualization, integrating with various AI tools via MCP.

An experimental security extension for the Model Context Protocol (MCP) providing runtime evidence for tool calls via HTTP message signatures and mTLS.

A library of 166 ready-to-use Agent Skills plus 100+ scientific database integrations that turn AI coding agents into research assistants for biology, chemistry, medicine, drug discovery and data analysis.

Ponytail is an AI coding-agent skill/plugin that nudges agents toward minimal, necessary code using a seven-rung decision ladder, plus review/audit commands. It supports Claude Code, Codex, Copilot CLI, Gemini, OpenCode, and many other coding tools via plugin installs or ruleset files.

FastGPT is a knowledge base platform based on large language models, providing out-of-the-box capabilities such as data processing, RAG retrieval, and visual AI workflow orchestration, supporting rapid construction and deployment of complex Q&A systems.
