Curated map of 3,000+ open-source AI agent tools: coding agents, agent frameworks, MCP servers, RAG, memory and local LLMs, sorted by layer and ranked by GitHub stars.
MCPpedia last refreshed this data
Awesome AI Agent Stack is an MCP server that curated map of 3,000+ open-source AI agent tools: coding agents, agent frameworks, MCP servers, RAG, memory and local LLMs, sorted by layer and ranked by GitHub stars. Its tool list has not been published yet over stdio, sse and http, requires no API key, and scores 41/100 on MCPpedia's security, maintenance and efficiency rubric.
Config is the same across clients - only the file and path differ.

3,000+ tools across 29 categories, ranked by GitHub stars. Each section is split into sub-groups by what the tools do. Every entry passes a mechanical bar: real, public, not archived, and actively maintained (pushed in the last 12 months); new additions also need 1,000+ stars. Every link is re-checked against the GitHub API, and projects under 10,000 stars that stop being maintained are pruned. Organized as a stack so you can find the right tool for each layer of an agent system.
