# AgentReady v2.0 adds AR-ACT-10, an MCP server or CLI as a MUST

2026-10-20

AgentReady v2.0 was merged on 21 Oct 2026 and makes an MCP server or a CLI a MUST for products that agents act on. It also raises WebMCP to SHOULD and adds four identifiers, so a product that conformed to v1.0 can now fail.

## What changed

The spec repository moved to v2.0 in commit 8eff705, merged 21 Oct. AR-ACT-10 requires an MCP server or a CLI for products agents act on, AR-ACT-07 WebMCP rises to SHOULD, and AR-FIND-04, AR-READ-11, AR-ACT-08 and AR-ACT-09 are new. A v1.0-conformant product may fail v2.0.
