Pulse: A Local Monitor for Claude Agent Activity

Pulse is a local application designed to monitor and manage Claude agent activity directly from a user's terminal session.

Developed by a student from Flanders, this open-source tool provides real-time visibility into token usage and associated costs for developers working with Anthropic's Claude models.

Its primary function is to offer a transparent view of an AI agent's operations, a feature often obscured in standard API interactions or cloud-based dashboards. Users can track expenditures as they occur, ensuring better budget control.

A notable feature allows for remote approval of tool calls, enabling developers to oversee and grant permissions to their Claude agents from a mobile device, even when away from their primary workstation.

The application emphasizes local execution and privacy, operating without requiring an account or transmitting data to external cloud services. This local-first approach could appeal to developers or small teams prioritizing data sovereignty and cost transparency when experimenting with or deploying Claude agents.

...easily follow what your claude agent is doing right now in your terminal session with an ambiance design and easily give permissions for your agent.

While Pulse offers a useful utility for individual developers and researchers, its impact on broader Tokyo business workflows remains limited. It addresses a niche technical need for those directly building and debugging AI agents, rather than a widespread professional pain point for general business users.
