Tier lists: which tools AI agents can use
The same tool can be great for one agent and weak for another. A coding agent needs a CLI. A server automation does not. So we rank every tool once per purpose, from S to D.
Coding agents9 in S tier · CLI and MCP count most. llms.txt and key auth are important. A public API, OpenAPI spec and sandbox are nice to have.Automation agents20 in S tier · Public API, key auth and OpenAPI count most. MCP is important. A CLI does not count, because servers rarely install one.Data agents3 in S tier · MCP and a sandbox (or branch) count most. API, CLI and key auth are important.Payment agents4 in S tier · Sandbox, public API and key auth count most. Without a sandbox the score stops at 50, so the tool cannot rank above C.
