Tokmeter — AI Agent Usage & Cost MCP server

Tokmeter

Every AI coding agent you run, on one ledger.

Tokmeter reads the session files your agents already write to disk and turns them into token and cost totals by project, model, provider, and day — across Claude Code, Codex, Gemini CLI, Cursor, and a dozen more. No API keys, no telemetry, no account. Your data never leaves the machine.

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.

What it looks like

macOS menubar — today's tokens and cost, always visible

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/drishti

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.
