Token Meter — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Token Meter (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Token Meter parses the JSONL files that Claude Code and Codex already write to disk and turns them into a real dashboard: cost per project, per model, per MCP tool, per hour. Your data never leaves your machine.
Use Token Meter if you:
claude --resume / codex resume command handyNot a fit if you need billing-grade numbers validated against your Anthropic or OpenAI invoice — Token Meter computes estimates from local JSONL files only.
When Token Meter is wired as an MCP server (install-mcp all), four tools become available to your AI assistant:
| Tool | What it returns |
|---|---|
usage_summary | Daily table of token counts, USD-equivalent cost, and call counts — broken down by day and model |
recent_sessions | Latest sessions with paste-ready claude --resume / codex resume commands |
session_tools | Per-tool breakdown inside a session: call count, total tokens, average latency, response size |
refresh_data | Re-scans your local JSONL logs for new activity, then returns a fresh summary |
All four are read-only. No data leaves your machine.
Copy-paste any of these into Claude Code or Cursor after installing the MCP server:
Show me my token usage and cost for the last 7 days.List my recent sessions so I can pick one to resume.Show the tool breakdown for my most recent session — which tool used the most tokens?Refresh token-meter data, then tell me which model cost the most this week.Which hour of the day am I spending the most tokens on?npx @whdrnr2583/token-meter ingest # scan ~/.claude/projects + ~/.codex/sessions
npx @whdrnr2583/token-meter stats 30 # CLI summary for last 30 days
npx @whdrnr2583/token-meter serve # http://localhost:8765 dashboard
npx @whdrnr2583/token-meter mcp # run as an MCP server for Claude Code / CursorThe package is published under an npm scope (@whdrnr2583/) because the baretoken-metername collides with an existing similar name on npm. The CLI binary is still calledtoken-meterafter install.
One command registers Token Meter with every supported client on your machine:
npx -y @whdrnr2583/token-meter install-mcp allHandles Claude Code, Cursor, and Claude Desktop — idempotent, backs up existing config, preserves other MCP servers. Single-client variants: install-mcp claude-code | cursor | claude-desktop. Add --dry-run to preview.
Or have your LLM do it. Open Claude Code / Cursor / Claude Desktop and ask: "Read https://raw.githubusercontent.com/whdrnr2583-cmd/token-meter/main/docs/mcp-server.md and set up token-meter as my MCP server."
Manual one-liners (if you'd rather not run our installer):
| Client | Command / config |
|---|---|
| Claude Code | claude mcp add token-meter -- npx -y @whdrnr2583/token-meter mcp then claude mcp list to verify |
| Cursor | Edit ~/.cursor/mcp.json (Windows: %USERPROFILE%\.cursor\mcp.json) — see docs/mcp-server.md |
| Claude Desktop | Edit claude_desktop_config.json — see docs/mcp-server.md |
| ChatGPT | Stdio-only for now; HTTP wrapper recipe in docs/mcp-server.md |
| Other (Continue, Zed, custom) | npx -y @whdrnr2583/token-meter mcp over stdio |
Then ask: "Use token-meter to show my recent sessions" or "Use token-meter usage_summary for this week".
Claude Code shortcut: runnpx -y @whdrnr2583/token-meter install-command claude-codeonce to register the/token-meterslash command. After reopening your session, type/token-meterfor a one-shot summary without natural language.

plan and want to know what the API would have cost.
tool is on average, response sizes per call.
Costs are estimates computed locally from the token counts that Claude Code and Codex already write to their JSONL files, multiplied by the model's published per-million-token rate. They are not validated against your actual Anthropic / OpenAI invoice and may diverge for several reasons:
src/pricing.ts is a snapshotthe API would have cost, not what you pay
approximated
Treat the numbers as relative signal for spotting waste, not as billing-grade accounting. Token Meter ships a regression test that the calculation is reproducible, and an audit script that checks invariants; neither verifies the rates against vendor invoices.

| Tier | Price | What you get |
|---|---|---|
| Free | $0 | Claude Code + Codex parsing, MCP/tool breakdown, hourly/model/project breakdown, 7-day history, 1 desktop alert |
| Pro | $5/mo | Everything in Free + 30-day history, unlimited smart alerts (desktop + webhook), session drill-down, cache efficiency, waste signals |
