Tokmeter

---

Why

Every agent bills you separately and shows you its own slice. Claude Code knows what Claude Code cost. Codex knows what Codex cost. Nothing knows what today cost, or which project is quietly burning the most, or whether the model you switched to is actually cheaper for the work you do.

Tokmeter answers that from data already on your disk. It parses each agent's local session logs, prices them against a live model catalog, and keeps an append-only daily ledger so history survives even after the agents rotate their own logs away.

npx @sriinnu/tokmeter --today

What it looks like

CLI — usage by project, model and provider	Digest — a weekly report card

There is also a terminal UI (tokmeter-tui), a local web dashboard, a statusline for Claude Code, and an MCP server so an agent can query its own spending.

Install

Requires Node.js 18+. Reading session files needs no provider credentials; pricing lookups fetch a public catalog, and --light skips them entirely.

# Try it without installing
npx @sriinnu/tokmeter --today

# Install the CLI, and the daemon/MCP server
npm install -g @sriinnu/tokmeter @sriinnu/tokmeter-mcp

Package	Contents
@sriinnu/tokmeter	Core API, CLI, and terminal UI
@sriinnu/tokmeter-mcp	MCP server, daemon, statusline, and live terminal UI

packages/core, packages/cli, and packages/tui are private workspace packages bundled into @sriinnu/tokmeter. packages/web is a separate private workspace app run from source.

Claude Code and Codex are the primary validation targets. See provider compatibility for the other parsers and their known limits.

CLI

tokmeter --today
tokmeter models --project my-app --json
tokmeter daily --week
tokmeter projects
tokmeter stats --month
tokmeter digest --period week
tokmeter pricing sonnet

Filters include --project, --claude, --codex, --week, --month, and --since YYYY-MM-DD --until YYYY-MM-DD. Use --json for machine-readable output and --light for token-only reports.

• Aliases: merge display names, tag projects, or hide them from lists.
• Backup and restore: portable snapshots, cleanup preview, restore. Cleanup deletes source files; keep the confirmation and backup steps.
• CLI reference: every command with examples.
• How the numbers work: what each bucket means and where estimates enter.

TypeScript API

The root export provides the core API. Convenience query helpers use the /cli subpath.

import { TokmeterCore } from "@sriinnu/tokmeter";
import { loadTokmeterSummary } from "@sriinnu/tokmeter/cli";

const core = new TokmeterCore();
await core.scan({ providers: ["codex", "claude-code"], today: true });
const models = core.getModelCosts();
const daily = core.getDailyBreakdown();

const summary = await loadTokmeterSummary({ week: true, light: true });

Reuse one core scan when querying several breakdowns. See integration guidance, core API usage, and SKILL.md for agent-facing integration instructions.

Daemon, MCP, and statusline

tokmeter-mcp daemon start
tokmeter-mcp daemon status
tokmeter-mcp serve             # MCP server over stdio
tokmeter-mcp statusline        # one statusline tick
tokmeter-mcp live              # live terminal UI

The daemon uses local HTTP port 9877 for queries and WebSocket port 9876 for live registration. The macOS app, statusline, and MCP server consume its shared state. Daemon commands belong to @sriinnu/tokmeter-mcp; install it for these surfaces.

MCP tools use the tokmeter_ prefix and cover usage queries, comparisons, forecasts, export, and confirmed cleanup/restore operations. See the MCP reference for names, configuration, and programmatic exports.

tokmeter-mcp editors lists installer targets. tokmeter-mcp install-mcp and tokmeter-mcp install-statusline write editor configuration; inspect the generated settings for your editor. See architecture for registration, authentication, refresh, storage, and daemon lifecycle details.

Terminal and web interfaces

# After installing @sriinnu/tokmeter
tokmeter-tui

# Without a global install
npx -p @sriinnu/tokmeter tokmeter-tui

The terminal UI supports overview, model, daily, and statistics views. See its keys and commands.

Run the web workspace from a source checkout:

bun install
bun run dev:web

Open http://localhost:3000. See web setup and data sources.

macOS app

Release builds target Apple silicon and macOS 14+. Node.js 18+ with npx is also required for the local daemon.

Install @sriinnu/tokmeter-mcp, run tokmeter-mcp daemon start, then open TokmeterBar from /Applications. Download the app from GitHub Releases.

The popup gives today's tokens and estimated API cost equal prominence, with models and projects below. Chart hover cards show exact daily tokens and cost. Usage details expands lifetime totals, trends, and signals. Six themes are selectable: Terminal, Paper, Prism, Lagoon, Carbon, and Glass. The Hub provides larger breakdowns and settings. Settings → Open web dashboard starts its local server on demand; Stop web dashboard or quitting the app stops it.

See macOS build and runtime details, first-use checks, and popover validation. The completion tracker records remaining fresh-machine, reliability, update, accounting, accessibility, and trial gates.

The synthetic walkthrough documents how the example images were generated; it is not a capture of a current local candidate.
