The company says developers can retrieve CPU, memory, disk, replication lag and connection figures through an AI assistant without leaving their editor.

PlanetScale announced a tool for retrieving database branch metrics through its MCP server in a changelog entry dated October 9, 2026. Called planetscale_get_branch_metrics, it brings those readings into an AI assistant, according to the company.

The tool pulls five categories of data: CPU, memory, disk, replication lag and connections. PlanetScale describes the benefit as keeping those figures close at hand—developers can check them without leaving their editor.

The short announcement leaves several practical details unstated. It does not identify supported database engines, explain the time window or granularity of the readings, or specify the permissions needed to retrieve them. The available evidence establishes what PlanetScale announced, not how well the tool performs in troubleshooting; no hands-on test is included in the supplied material.
