What & why

Every tool here is a published algorithm — ISO 7064 MOD 11-2, Luhn, MOD-97, GB 11643 — computed in code, so the same input gives the same answer today and in five years. Nothing calls a model and nothing calls a third-party lookup service, so nothing here can break because someone else changed an API.

What is deliberately not here: phone-number carrier lookup, full administrative-division tables, courier detection. Those need external databases that change, or differ by locality. No reliable data, no tool — a "roughly right" answer would destroy the point of this pack.

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

18 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.

Tool	What it does	Arguments	Price / call
what_can_you_do	Describe a task in plain language (any language) and get back exactly which tools on this server do it, with ready-	task	—
unit_convert	Convert units: length, weight, temperature, area, volume, speed, data size. value + from + to (e.g. 100 km mi, 25 c	value, from, to	$0.001

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

curl -s -X POST https://ainetcafe.com/mcp/validate -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Install

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

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

Deterministic, no model calls: $0.001 per call, inside the free anonymous quota. 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-validate — 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.

Compatibility & permissions (at a glance)

What runs locally	Nothing. Ships one cordis.patch.yml row; there is no tool code, no build step and no lifecycle script in this package.
Filesystem access	None.
Shell / process access	None.
Network access	Outbound HTTPS to ainetcafe.com only, from the MCP client that dsh already ships.
Credentials	None required for the free tier. An optional AllRouter key, if you supply one, is sent by dsh as a request header and is never stored by us.

A directory listing is not a security review. Read cordis.patch.yml — it is short enough to read in full in under a minute.
