Which AI agent platforms, frameworks and infrastructure products publicly document support for the protocols that determine how agents connect to tools, talk to each other, prove who they are, and spend money.
MCP (Model Context Protocol) is how an agent calls external tools and data sources. A2A is agent-to-agent coordination — discovering and delegating to other agents. Signed means agent actions or identities are cryptographically signed, which is what makes an action attributable after the fact. Payments means the agent can transact, via protocols such as x402 or AP2. Definitions and the source hierarchy behind each field are in the methodology.

45 platforms. Each row links to a full profile with its primary source and evidence level. Rows are re-checked on a rotating schedule; the date shown is when that entry was last verified against its sources.
Freshness. This table is generated from the directory dataset, so it always matches the profile pages exactly. Listings are re-verified on a rotating basis covering the full set roughly every 3–4 weeks. Oldest row currently on this page: 2026-09-08. Most recent: 2026-09-28. If the oldest date is more than eight weeks behind today, treat this table as stale and check the individual profiles and their primary sources instead.
