Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

File ships in the package but is absent from the source [пакет] ledger_agent/__init__.py:1, [пакет] ledger_agent/__main__.py:1, [пакет] ledger_agent/alerts.py:1 и ещё 34

этот файл ставится пользователю, но в репозитории его нет

Builds a file path from a variable [пакет] ledger_agent/benchmark_cost.py:205

    json_path = os.path.join(out_dir, f"{base}.json")

Runs an external command [пакет] ledger_agent/bridge.py:52

        out = subprocess.run(argv + ["--json"], capture_output=True,

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Perseus Ledger — verifiable, hash-chained event provenance — questions

Answers built from our own checks of this server.

Why is there no uptime for Perseus Ledger — verifiable, hash-chained event provenance?

Perseus Ledger — verifiable, hash-chained event provenance runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package perseus-ledger was installed 131 times last week.

Is Perseus Ledger — verifiable, hash-chained event provenance still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Perseus Ledger — verifiable, hash-chained event provenance?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls perseus-ledger straight from pypi; nothing to host, nothing to sign up for.

How many people use Perseus Ledger — verifiable, hash-chained event provenance?

The pypi package perseus-ledger was installed 131 times in the last week. Week over week that is -49%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
