AI Agent Tools Directory – 316 tools for building AI agents

Big, filterable index with clear category pills, a prominent search box and daily-updated counts — handy for quickly scanning the agent ecosystem. Feels like a thoughtful curation (MCP servers, memory, platforms called out) but it stops short of being decisive: there are few trust signals, no standardized metadata (pricing, license, maturity) and no side-by-side comparisons, so it’s a great starting point rather than the final answer when choosing tooling.
