View your Claude Code usage statistics directly inside VS Code. Local-only — no API key, no network access, nothing leaves your machine.
Features
Dashboard webview in the activity bar with tokens, cost, sessions, cache efficiency, and streaks
Per-project breakdown showing where your tokens and dollars are going
Spending view with model, session, tool, and MCP-server cost attribution
Environmental context translating token usage into energy, CO₂, and comparable everyday figures
Work profile — distribution of the nature of your work across projects
Auto-registers a local MCP server so your AI agent can query stats directly ("how many tokens did I use this week?")
Requirements
Node.js 22.5+ on your PATH (uses the built-in node:sqlite module)
Claude Code installed and used at least once — the extension reads from ~/.claude/projects/
Getting started
Install the extension
Click the Claude Stats icon in the activity bar, or run Claude Stats: Open Dashboard from the command palette
Restart Claude Code so it picks up the MCP server the extension auto-registers in ~/.claude.json
That's it. The extension reads Claude Code's local JSONL session files, aggregates them into a local SQLite database at ~/.claude-stats/stats.db, and renders the dashboard on demand.
MCP tools available to your agent
Once installed, ask your AI agent things like:
"How many tokens have I used this week?"
"What were my most expensive sessions today?"
"Which projects am I spending the most on?"
"How much CO₂ did my Claude usage cause last week?"
