# wanderbooks
|
|
|
|
Canonical double-entry bookkeeping, rebuilt from scratch. The engine is
|
|
verified against oracles, parity is tracked automatically, and the primary
|
|
interface is AI-first: you talk to an agent, the agent drives the books
|
|
through MCP. Self-hosted, no rent.
|
|
|
|
## What it is
|
|
|
|
- **`ledger-core`** — the semantics engine. Exact decimal money, five
|
|
account types, balanced journal entries, immutable posted log with
|
|
reversing entries, trial balance, P&L, balance sheet, indirect-method
|
|
cash flow, fixed-asset register with straight-line depreciation.
|
|
- **`ledger-store`** — durable storage. The source of truth is an
|
|
append-only, hash-chained JSONL journal; SQLite is a disposable
|
|
projection rebuilt from it; receipts live in a content-addressed blob
|
|
store. Drafts are durable, corrupt projections self-heal.
|
|
- **`ledger-mcp`** — the AI-first interface. 64 MCP tools over stdio or
|
|
Streamable HTTP: draft → preview → post workflow, server-side receipt
|
|
policy (>$25), anti-splitting detection, asset management, digest for
|
|
human review, plus read-only resources for dashboards.
|
|
- **`ledger-import`** — QuickBooks interop. Import bank/credit-card CSVs
|
|
and chart-of-accounts CSVs; export IIF journal entries (for QuickBooks
|
|
Desktop) and XLSX reports.
|
|
- **`ledger-config`** — the company settings in a books dir's
|
|
`wanderbooks.toml`.
|
|
- **`ledger-gui`** — the viewer: a read-only, live window on the books for owners and their
|
|
accountant (egui). Answers first (cash, runway, profit, what needs
|
|
attention), then every number drills down to its lines, its entry, the
|
|
rendered receipt, and the journal history. Follows the journal live:
|
|
a change the agent makes appears in milliseconds. `--demo` opens a
|
|
realistic demo company.
|
|
|
|
## Verification
|
|
|
|
This is the storytold way applied to accounting: agents verify against
|
|
oracles, never ship what they haven't demonstrated.
|
|
|
|
- 70 workspace tests: invariant tests encoding accounting law, golden-file
|
|
report snapshots, property tests (proptest), end-to-end MCP stdio tests.
|
|
- Mutation testing via cargo-mutants; fuzzing via cargo-fuzz (11.5M+
|
|
executions, zero crashes).
|
|
- GnuCash is the behavioral oracle (never a code source — clean room,
|
|
MIT OR Apache-2.0).
|
|
|
|
## Status
|
|
|
|
Parity is 12 of 12 against the spreadsheet workflow it replaces
|
|
(`docs/capability-parity.md`). The parallel-run plan
|
|
(`docs/parallel-run.md`) is written; the Google Sheet stays the system of
|
|
record until a clean month and explicit cutover approval.
|
|
|
|
See [`plan/STATUS.md`](plan/STATUS.md) for where things stand and
|
|
[`plan/roadmap.md`](plan/roadmap.md) for where it's going.
|
|
|
|
## Quickstart
|
|
|
|
```bash
|
|
cargo test # whole suite
|
|
cargo run -p ledger-mcp -- --data-dir /tmp/books # MCP server over stdio
|
|
cargo run -p ledger-gui -- --demo # the viewer, on a demo company
|
|
```
|
|
New books, one command (installs Rust and wanderbooks if needed, makes the
|
|
books dir with the MCP server registered for it, and starts the agent):
|
|
|
|
```bash
|
|
curl -fsSL https://wanderbooks.ai/install.sh | sh -s -- ~/Books/Acme
|
|
```
|
|
|
|
Already installed: `wanderbooks new ~/Books/Acme` (add `--codex` to keep the
|
|
books with Codex instead of Claude Code). In a books dir, `just`
|
|
lists the shortcuts (`just gui`, `just agent`, `just backup`).
