Read, write and search records in a Kintone app, plus comments, files and form metadata, via each customer's own Kintone REST API.
Kintone ships in the w6w first-party pack. It declares 12 actions, 2 health checks, and the host runs its code in a sandbox that never sees the credential.
io.w6w.kintoneKintone (Cybozu) is a no-code database/app builder: every customer runs their own tenant at https://<subdomain>.cybozu.com or https://<subdomain>.kintone.com, and every Kintone “App” inside that tenant is its own record schema the customer designs, not a fixed shape this integration can assume. So, like bubble, mautic and tableau in this pack, the tenant’s own URL is a connection field and the field-value shapes are passed through as the raw objects Kintone’s REST API documents ({"FieldCode": {"value": ...}}), rather than guessed at.
This app covers the REST API surface that a per-App API Token can reach: single and bulk record create/read/update/delete, a query-string search over a Kintone App’s records, comments, file upload/download, and the two read-only App metadata calls (general info, form fields) documented as API-Token-authenticated. Left out on purpose: listing every App in the tenant and anything about Kintone’s own Users/Groups/Spaces admin surface, because those require Password, Session or OAuth 2.0 authentication — a Kintone API Token is deliberately scoped to one App and cannot reach them (verified against Kintone’s own Authentication reference; see the README).
Three routes to the same 12 actions. The Workflow tab is generated from Kintone's own manifest and carries its real ids, so it is copy-pasteable; the Code and CLI examples are the same call for any action on any app, so every app-specific value in them is a blank you fill in.
comment-add Post a comment to a record, optionally mentioning users, groups or departments.
file-download Download a file attached to a record, by the fileKey found on its Attachment field.
file-upload Upload a file to Kintone and get back a fileKey for use in an Attachment field.
record-update Change field values on one record, addressed by Record ID or a unique key.
records-delete Permanently delete up to 100 records by Record ID. Kintone has no single-record delete endpoint.
A workflow step names the app and the action, and the editor fills in the
connection when you pick one. This is the Step shape from the
workflow spec, carrying Kintone's real ids.

Every app-specific value here is a blank you have to fill in. An
app action is reached through the connection that authenticates it, so the
address is a connection id, not the app id — and connections belong to your account,
so a public page cannot know yours. Create one for Kintone, then fill in
the three blanks: conn_YOUR_CONNECTION_ID, the action key, and the
parameters that action declares. The call itself is real — the shape is transcribed
from the studio's own snippet builder, which prints the same kind of blanks — but
nothing in it is specific to Kintone. The Workflow tab is where this app's
real ids are.

One MCP endpoint exposes every app, function and workflow the caller is entitled to, as tools it can discover and run. Access is granted per team while we onboard.
One tool call{
"name": "w6w_invoke",
"arguments": {
"ref": "app:io.w6w.kintone#app-fields-get",
"input": {
"appId": "<appId>"
}
}
}
Every tool names its target with a single ref. The
app: form above doesn't name a connection at all — the
host resolves which of the caller's Kintone connections to sign
with, and refuses rather than guesses when the answer is ambiguous.
The token is attached host-side, at the moment of the call. It is never a tool argument, never in the model's context, and never in a transcript — so a prompt injection has nothing to exfiltrate.
Tools are derived per end user from what that person has actually connected and is entitled to — not one shared bot identity carrying the union of everyone's access.
Multi-step work runs on the workflow engine and returns a run handle the agent can poll — retries, branching and state survive the conversation that started them.
Kintone's declared health checks are on the surface too, so an agent can tell "the vendor is down" from "your credential expired" before it burns a retry on either.
The MCP surface is part of the hosted platform. Kintone itself is MIT, and the runtime that executes it is source-available (FSL).
Kintone declares its own checks, so its health is a property of the app rather than something the host guesses at.

This connection's own Kintone tenant, via an unauthenticated request — Cybozu's edge answers a generic HTML page for an unprovisioned subdomain, while a live tenant's own REST API answers its documented JSON error shape even without a credential.
