Open site Open in the app JSON README (API)READMELoading documentation…# burnmeter burnmeter analyses Claude Code token spend from the session logs already on your machine. It reads the JSONL session files, adds up the token counts in every usage record, and reports two views: how the total splits across output, input, cache-creation, and cache-read (the efficiency view), and the full totals with a per-model split (the breakdown view). One binary serves a command-line interface and a stdio MCP server. Everything is local. There is no network access, no API key, and no account. The log directory is taken from `CONTEXTBURN_LOG_DIR` when set and defaults to `~/.claude/projects`; every `*.jsonl` file under it is read recursively. ## Install ```bash npx @reneturcios/burnmeter breakdown ``` Or run the container image: ```bash docker run -i ghcr.io/cloudcorprecords/burnmeter ``` The container defaults to the MCP server (see below). Pass CLI arguments to use it as a CLI instead. Note the container reads logs from inside the container, so mount your log directory and point `CONTEXTBURN_LOG_DIR` at the mount if you use it for real logs. ## CLI ```bash burnmeter efficiency burnmeter breakdown burnmeter breakdown --log-dir ~/somewhere/else burnmeter --version ``` Both reports print JSON. `--log-dir` wins over `CONTEXTBURN_LOG_DIR`, which wins over the `~/.claude/projects` default. Exit codes: `0` on success, `1` when a report fails, `2` for usage errors. A breakdown contains `logDir`, `filesScanned`, `entriesWithUsage`, `malformedLines`, `totals` (the four token counts plus `total_tokens`), and `byModel` (the same counts per model, with an entry count, sorted by total tokens descending). An efficiency report contains the same scan fields and totals, plus `shares`: each category as a percentage of total tokens, rounded to two decimal places. How entries are counted: a log line that is not valid JSON (or not a JSON object) is skipped and counted in `malformedLines`. An entry counts when it carries a usage object, either at the top level or under its `message`; the four counts `input_tokens`, `output_tokens`, `cache_creation_input_tokens`, and `cache_read_input_tokens` are summed, with a missing or non-numeric field counting as 0. The model is `message.model`, falling back to a top-level `model`, falling back to `unknown`. Entries without a usage object are ignored. When the directory is missing or no usage entries are found, the report is not an error and no numbers are invented: totals and shares are zero, and the report carries a `note` field saying no usage entries were found and where it looked. ## MCP server One bin serves both faces. The `mcp` subcommand starts a stdio MCP server: ```bash npx -y @reneturcios/burnmeter mcp ``` MCP client configuration: ```json { "mcpServers": { "burnmeter": { "command": "npx", "args": ["-y", "@reneturcios/burnmeter", "mcp"] } } } ``` To read logs from a non-default directory, add `CONTEXTBURN_LOG_DIR` to the client's `env` for this server. ### Tools Both tools are parameterless, as documented in the original tool's public spec. | Tool | Input | What it returns | | --- | --- | --- | | `run_efficiency` | (none) | The efficiency report: totals plus each category's share of total tokens. | | `spend_breakdown` | (none) | The full breakdown report: totals plus the per-model split. | ## Development ```bash npm install npm run build # tsc -> dist/ npm test # node test runner over test/*.test.ts, no network (temporary fixture logs only) npm run dev # run the CLI from source via tsx ``` ## License MIT — see `LICENSE`.
