Our reading of LogCarverGuard, from the data

LogCarverGuard is a database MCP server from caiderek, listed in the official MCP Registry.

We haven't measured its tool list yet, so its token cost is unknown.

Maintenance is active: the last public signal was in the last day (2026-10-18). For comparison, 64% of database servers are active or maintained.

With 1 GitHub stars it ranks #538 of 1,397 database servers we index.

It runs locally on your machine over stdio and needs one secret (LOGCARVERGUARD_CONNECTION_STRING); use a scoped, least-privilege key.
