Heartbeat Silence Check

A local MCP server that checks whether a heartbeat file's modification time has passed a silence threshold, flagging a stalled workspace heartbeat.

What you can do

Reads the modification time of the workspace heartbeat file and compares it against a silence threshold, defaulting to a set value, to report whether the heartbeat has gone quiet. The description names a single check rather than a set of tools, so the assistant gets a silence verdict for that file. It is a narrow monitoring helper for one specific file path in a workspace.

When to use it

Use it when an assistant or workflow needs to notice that a workspace heartbeat file has stopped being updated, for example to detect a stalled agent or scheduled job. It is not a general monitoring or alerting tool.

Requirements

Runs as a local process on the user's machine (stdio transport) and is desktop only. It expects a workspace file at workspace/system_memory/heartbeats.json to exist and be readable. No packages, environment variables, headers or authentication are declared.
