tokencat 0.4.0

Local-first, read-only AI coding agent token and usage inspector.

TokenCat

TokenCat is a local-first, read-only CLI for understanding how AI coding agents are being used on your machine.

If you jump between Codex, Gemini CLI, and Copilot CLI, TokenCat gives you one terminal-native view for sessions, models, tokens, and API-equivalent cost estimates without proxying traffic, rewriting endpoints, or touching your prompts and responses.

Why TokenCat

• One place to inspect Codex, Gemini CLI, VS Code Copilot Chat/Agent usage, and Copilot CLI session-state totals
• A default 0-argument dashboard: just run tokencat
• Read-only by design: no proxying, no interception, no auth-token handling
• Local pricing estimates with clear coverage for unknown or unattributed usage
• JSON output for scripts and terminal output for humans

Install

Python 3.11+ is required.

pipx install tokencat

Upgrade later with:

pipx upgrade tokencat

If you want to try the repo directly:

pipx install .

Quick Start

Open the dashboard:

tokencat

Look at a longer window:

tokencat --since 30d

Focus on one tool:

tokencat dashboard --provider codex

List recent sessions:

tokencat sessions --provider codex --limit 20

Inspect model totals:

tokencat models --provider gemini

Check local detection and health:

tokencat doctor

Inspect or refresh pricing data:

tokencat pricing show
tokencat pricing refresh

What You Get

• A dense terminal dashboard with provider health, token totals, pricing coverage, daily usage, and recent sessions
• Session-level views with anonymous IDs by default
• Model-level aggregation across supported tools
• A bundled pricing catalog, plus a local cache that can refresh itself on first use
• Stable JSON envelopes for scripting and automation

Supported Tools

Tool	Status	Notes
Codex	Supported	Reads ~/.codex/sessions/**/*.jsonl and ~/.codex/archived_sessions/*.jsonl, then falls back to ~/.codex/state_*.sqlite when needed.
Gemini CLI	Supported	Reads ~/.gemini/tmp/**/chats/session-*.json and non-sensitive settings metadata.
GitHub Copilot	Supported	Reads VS Code `workspaceStorage//chatSessions/.json

Pricing

TokenCat can estimate API-equivalent cost for models with known pricing data.

• Pricing works offline by default using the bundled catalog shipped with the package.
• On first pricing use, TokenCat silently tries to refresh its own cache under ~/.tokencat/pricing/.
• If that refresh fails, it quietly falls back to the bundled catalog.
• tokencat pricing refresh manually refreshes the local cache.
• Pricing resolution is source-aware: direct source price first, then official API price, then OpenRouter as the marketplace fallback.
• JSON output includes pricing_source so you can see whether a session or model was priced from the direct source, an official vendor catalog, or OpenRouter.
• Metadata-only rows in the upstream dataset are ignored; TokenCat only treats entries with explicit price fields as priced.
• Unknown or historically renamed models are shown clearly instead of being guessed.

Current pricing references:

• OpenAI API pricing
• OpenAI Codex pricing
• Gemini API pricing
• Anthropic models and pricing
• xAI models
• OpenRouter pricing
• GitHub Copilot plans

Privacy

TokenCat is intentionally conservative.

• It only reads local files that already exist on your machine.
• It does not proxy traffic or intercept requests.
• It does not rewrite provider endpoints or mutate provider sessions.
• It does not read OAuth credentials for reporting.
• It never prints raw prompt or response bodies.
• It redacts sensitive local metadata by default.

To reveal more local metadata in session listings:

tokencat sessions --show-title --show-path

JSON Output

All JSON commands keep a stable top-level shape:

• generated_at
• filters
• providers
• summary or items
• warnings

That makes TokenCat easy to pipe into scripts, local dashboards, or personal automation.

Common Flags

• --provider codex|gemini|copilot
• --since / --until with values like 7d, 24h, or ISO dates
• --json
• --no-price

Session listings also support:

• --limit
• --model
• --show-title
• --show-path

Limits

• TokenCat is macOS-first today.
• Linux path hooks are present, but Linux is not yet a polished target.
• Windows is not yet supported.
• Copilot support covers VS Code Chat/Agent sessions plus standalone CLI shutdown summaries under ~/.copilot/session-state/. Active CLI sessions without a shutdown summary are detected but not yet counted.
• Cost is an estimate, not your actual bill.
