Coding Agents: AI agents, MCP servers and skills
Agents and tools that write, review and refactor code.
AI Agents
AutoGPT
AutoGPT is the vision of accessible AI for everyone, to use and to build on. Our mission is to provide the tools, so that you can focus on what matters.
Langchain
The agent engineering platform.
Gemini CLI
An open-source AI agent that brings the power of Gemini directly into your terminal.
MetaGPT
🌟 The Multi-Agent Framework: First AI Software Company, Towards Natural Language Programming
Oh My Openagent
OmO: Just type "mass ulw" keyword with your prompt. Now you are the master of graph engineering.
Openinterpreter
A coding agent for open models like Kimi K3 and GLM 5.3
MCP Servers
Headroom
Compress tool outputs, logs, files, and RAG chunks before they reach the LLM. 20% fewer tokens for coding agents, 60-95% fewer tokens for JSON, same answers. Library, proxy, MCP server.
Context Mode
Context window optimization for AI coding agents. Sandboxes tool output (98% reduction), persists session memory, and enforces routing across 17 platforms via MCP + hooks.
Code Review Graph
Local-first code intelligence graph for MCP and CLI. Builds a persistent map of your codebase so AI coding tools read only what matters, with benchmarked context reductions on reviews and large-repo workflows.
Serena
A powerful MCP toolkit for coding, providing semantic retrieval and editing capabilities - the IDE for your agent
Mastra
Mastra is the modern TypeScript framework for AI-powered applications and agents.
Fastmcp
🚀 The fast, Pythonic way to build MCP servers and clients.
Agent Skills
Rea
Reverse engineer anything with agents, from app behavior down to native binaries.
Agent Skills
Production-grade engineering skills for AI coding agents.
I Have Adhd
A skill to stop your coding agent from burying the answer. ADHD-friendly output.
Open Code Review
Secure, fast, efficient, battle-tested at Alibaba's scale. Hybrid architecture code review tool: deterministic pipelines + LLM Agent, precise line-level comments, built-in multi-language ruleset (NPE, thread-safety, XSS, SQL injection), OpenAI & Anthropic compatible.
Agent Skills For Context Engineering
A comprehensive collection of Agent Skills for context engineering, multi-agent architectures, and production agent systems. Use when building, optimizing, or debugging agent systems that require effective context management.
React Doctor
Your agent writes bad React. This catches it

Questions
What are the best open-source coding agents tools?
This page lists 724 open-source AI agents, MCP servers and skills for coding agents, ordered by GitHub stars within each type. Open a listing to compare license, activity, install steps and what it can touch.
How do I choose a tool for coding agents?
Start from the job you need done, then compare recent activity, license and the access each tool asks for. Prefer the narrowest tool that does the job, and try it on a small task first.
Are these tools safe to install?
Not automatically. Each listing shows what the tool can touch and, where a scan has run, a dated report for one commit. Read the source and limit the access you give it.
Can I add my project to this category?
Yes. List it free on AgenticMart and pick the category that fits. Paid selling opens soon.
