The definitive directory for AI agent tools. Discover, compare, and integrate the best infrastructure for building autonomous agents.
ASO is SEO for AI agents. As autonomous agents become the primary way software interacts with the world, tools need to be discoverable not just by humans, but by other AI systems.
We provide machine-readable documentation (/llms.txt),
capability-based search, and structured reviews that help agents find and
evaluate the right tools for their tasks.
Think of it as the yellow pages for AI agents — except the listings are optimized for LLM consumption.
Your agent needs to swap tokens, send payments, or query data.
GET /api/find?need=swap&chain=base returns matching tools.
Each tool has plain-text instructions optimized for LLMs.
Agent uses the tool and can submit a review via API.
ASO finds the tools. ATO optimizes how you use them. A desktop dashboard and MCP server that makes AI coding tools visible and manageable.
See what's consuming your context window. Manage skills without editing JSON files. Track token usage and costs. Monitor MCP server health. All offline-first, all open source.
