## Body
MCP Registry releases published MCP Registry v1.8.7. This automated release-watch entry was generated from the project's official GitHub release feed and is kept separate from human-reviewed editorial analysis. Release notes: Adds prepared listing JSON to avoid repeated decoding and rebuilding of server payloads on listing reads. Prepared reads are disabled by default and support bounded backfill and flag rollback. Listing rows release their database connection before JSON processing; pool defaults remain 60/10. Focused response/update/delete/backfill/rollback checks passed. Local encoding benchmarks over saved public records measured 63% less encoding time and 88% fewer allocations. These are encoding-cost results, not a peak-capacity guarantee. Broad staging replay remained inconclusive for capacity due to generator port exhaustion and losses.

## Recommended actions
- Review the official MCP Registry releases release notes before upgrading.
- Check compatibility, migration, and security notes against your current agent stack.
- Run focused regression tests before production rollout.
