Global tax and accounting knowledge built with accountants around the world, with official sources and transparent authorship and review status.
This connects Kimi Code CLI to the Open Accountants knowledge network, so Kimi can answer tax and accounting questions from Guides that cite an official source and carry an explicit review status, instead of from recall.
Two parts, and the first one is enough on its own:
- The MCP server, which gives Kimi 14 tools. One command.
- An Agent Skill, which tells Kimi when to use those tools and how to report jurisdiction, sources and review status. Optional but recommended.
kimi mcp add --transport http open-accountants https://www.openaccountants.com/api/mcpConfirm it works:
kimi mcp test open-accountantsYou should see ✓ Connected and 14 available tools.
Kimi discovers Agent Skills from ~/.kimi/skills/.
Copy the skill in:
git clone https://github.com/openaccountants/kimi-code-plugin.git
mkdir -p ~/.kimi/skills
cp -R kimi-code-plugin/skills/using-open-accountants ~/.kimi/skills/To scope it to one project instead, copy it to .kimi/skills/ in that project.
Kimi also reads ~/.claude/skills/, so if you already keep skills there, that
directory works too.
Restart Kimi. The skill is loaded when its name and description appear in the session's skill list.
Kimi Code CLI plugins are local executable tools declared in a plugin.json,
which is a different mechanism from MCP servers. A remote MCP server like this
one cannot be delivered as a Kimi plugin; it is added with kimi mcp add, and
the knowledge layer ships as an Agent Skill. The repository keeps the
kimi-code-plugin name for continuity with the other Open Accountants
integration repositories.
No key or configuration is needed to connect. Anonymous use is capped at a small number of free questions, after which the server returns a sign-in prompt with a link to create a free account. The Guides themselves are free to read.
As of 5 August 2026 the live network holds 1,790 Guides across 244
jurisdictions: 188 country-level jurisdictions, 52 US state-level
jurisdictions, and 4 regional or cross-border groupings. Of those Guides, 188
carry an attestation from a credentialed accountant; the rest are
accountant-authored or source-cited drafts. Coverage per jurisdiction is uneven,
and list_jurisdictions reports the per-jurisdiction counts so you can see what
is thin before you rely on it.
Topics covered: income tax, corporate tax, VAT/GST and sales tax, payroll, audit and audit exemption, company formation and entity choice, capital gains, crypto, tax residency, filing deadlines, and cross-border and relocation taxation.

Guides are authored by accountants and carry one of three review states, which the tools return with every result:
| State | What it means |
|---|---|
| Source-cited draft | Published with citations to official sources. No credentialed human has reviewed it. |
| Accountant-authored | Written by an accountant with a public licence number on file. |
| Attested by another accountant | A second credentialed professional has publicly stood behind that version. |
Verification is fact by fact, and the accountant who attests is named and personally accountable. A cited official source proves where a rule came from, not that it is still current. Confirm figures against the source before acting.
- No credentials to configure. The Guides are public and the server connects without a key. See the limits section above.
- What is sent. Only the query text your prompt produces (the topic and the jurisdiction). No files, no code, no credentials.
- Read-only by default. Thirteen of the fourteen tools only read. The one
exception,
share_with_openaccountants, sends a correction or a question to the network, and only when you explicitly ask for it. - Transport. HTTPS to
https://www.openaccountants.com/api/mcp. - To restrict to reads only, add
"disabledTools": ["share_with_openaccountants"]to theopen-accountantsentry in~/.kimi/mcp.json. - Full policy: https://www.openaccountants.com/privacy
Open Accountants is a research layer. It gives you the reviewed method, the official source, and a named professional where one exists, which is more than a guess and less than advice. Anything that ends in a filing position, a valuation, or a number a tax authority will see should go past a qualified local accountant first.
