Summary
AWS's Bedrock AgentCore Agent Registry, the private governed catalog for discovering and approving agents, tools, skills, and MCP servers first previewed in April 2026, graduated on August 6, 2026 to a dedicated agent-registry namespace. Support for the original preview bedrock-agentcore namespace will be discontinued on September 17, 2026, signaling the registry's move toward production-grade agent governance.
What changed
AWS moved the Agent Registry to a standalone agent-registry namespace on August 6, 2026 (retiring the preview bedrock-agentcore namespace on September 17, 2026), advancing the governed catalog for agents, tools, skills, and MCP resources beyond its April preview.
Why it matters
Governed discovery is becoming a control-plane feature as enterprises accumulate more agents, tools, and MCP endpoints; promoting the registry to its own namespace and setting a preview-retirement date signals AWS is hardening agent governance toward production, alongside parallel moves from Databricks (Unity Catalog) and Anthropic (self-hosted Claude Code).
