VERDICT

Should I use AI Agent Index?

The 2025 AI Agent Index documents the origins, design, capabilities, ecosystem, and safety features of 30 prominent AI agents based on publicly available information and correspondence with developers. - aiagentindex.mit.edu

Depends. Use it if you research, procure, or govern AI agents and want free, documented capability and safety data. Skip it if you want ratings, pricing, or reviews to choose a vendor.

Confidence

Medium. Based on 20+ public sources; no independent user reviews or commercial pricing data found.

Gotchas - check before you buy

Easy to confuse with commercial site — different product, different owner.

medium

No pricing, trial, or vendor support info — useless as a standalone buying tool.

low

Coverage fixed at 30 agents; new agents appear slowly or never.

Pros and cons

Pros

  • Free, public research database on deployed AI agents
  • Documents 30 prominent agents' capabilities, ecosystem, and safety features
  • Includes developer correspondence beyond marketing claims
  • Cited in IETF and NIST policy and standards work
  • Safety-transparency findings picked up by Cambridge and security press

Cons

  • Only 30 agents — narrow snapshot, not a full directory
  • Documents rather than rates; no scores, pricing, or buyer guidance
  • Built on public information, so undisclosed capabilities stay hidden
  • Academic update cycle may lag a fast-moving agent market
