dsh-duizhang

Bank/credit statement PDFs and invoice batches into ledger-ready tables, then reconciled — on a shared key in integer cents, or with no shared key at all by amount, date window, reference numbers and fuzzy counterparty names.

What & why

The point is that it refuses to look right when it is wrong. reconcile_ledger compares in integer cents, so 0.1+0.2 never invents a phantom difference. extract_statement re-adds the running total independently (opening + credits − debits = closing) and, if it does not balance, names the row where it first breaks. match_transactions handles split (1:N) and combined (N:1) payments and declines to guess when the evidence is thin. dedupe_entities never merges anything — it shows the evidence, cross-checked against tax-ID checksums, and leaves the decision to a human.

Every set ships what_can_you_do — describe a task in any language, get the exact tool plus a ready-to-run call.

What's in this pack

15 tools, read from the live endpoint on 2026-08-22 — this table is generated, not hand-written, so it cannot drift away from what tools/list actually returns. The Arguments column is what the tool genuinely reads; it comes from the tool's own declared input schema.

— in the price column means the tool is not metered per call (session/trial-gated instead). Failed calls are never charged. Check it yourself:

Install

dsh plugin --profile <your-profile> add github:mario03690/dsh-duizhang

Thin config layer only (one @deepseek-ai/dsh-mcp-client row, shipped as cordis.patch.yml) — no tool code runs on your machine. Built against the MCP client config shape of the dsh v0.1 developer preview; verified against the live endpoint on 2026-08-22.

Cost, quota, privacy

Mixed. The table operations are deterministic and cheap ($0.002–$0.008). The two extractors read documents with a model: extract_statement $0.03, extract_invoices $0.05. Every response reports its exact USD cost; failed calls are not charged.

No signup for the free anonymous quota. Documents are processed in memory and not retained. The config URL carries ?s=dsh-duizhang — a channel tag identifying the install path, not you.

Disclosure: built and run by the team behind ainetcafe.com — our own service, free tier plus paid usage. Full bundle (everything at once): dsh-netcafe. MIT.
