Create, search and transition issues on a self-hosted Jira Data Center or Jira Server instance.
Jira Data Center ships in the w6w first-party pack. It declares 15 actions, 3 health checks, and the host runs its code in a sandbox that never sees the credential.
io.w6w.jira-data-centerJira Data Center is Atlassian’s self-hosted, clustered deployment of Jira — a genuinely different product from Jira Cloud (the sibling jira app in this pack), reachable at whatever domain a customer’s IT team gave it rather than a fixed *.atlassian.net host. This app treats that instance address the way it treats any self-hosted app’s URL — a connection field, not something a manifest can allowlist.
It covers the same day-to-day loop as the Cloud app — creating, searching, updating, transitioning and deleting issues; adding, listing and deleting comments; listing and reading projects; looking up and searching users — adapted to the classic v2 REST API Data Center actually serves: plain wiki-markup strings instead of Atlassian Document Format for descriptions and comment bodies, and usernames instead of Jira Cloud’s opaque account ids for assigning issues and identifying people.
Authentication is a Personal Access Token sent as a bearer credential — Atlassian’s own recommended method alongside OAuth 2.0, which this version skips because it requires registering an application link inside each target instance’s admin console before a single Connection can be made. A username/password Basic method is included as a fallback for instances where PAT creation is disabled. Boards and sprints (the separate agile API), attachments, issue links, worklogs and every admin-only surface are out of scope for a first version.
Three routes to the same 15 actions. The Workflow tab is generated from Jira Data Center'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.
issue-get-transitions List the workflow transitions available from the issue's CURRENT status — the ids `issue-transition` needs.
issue-transition Move an issue through its workflow. Status is not directly writable — use `issue-get-transitions` to find the id.
project-get-many List every project visible to the connection — the source of project keys.
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 Jira Data Center'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 Jira Data Center, 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 Jira Data Center. 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.jira-data-center#comment-add",
"input": {
"issueKey": "<issueKey>",
"body": "<body>"
}
}
}
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 Jira Data Center 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.
Jira Data Center'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. Jira Data Center itself is MIT, and the runtime that executes it is source-available (FSL).
Jira Data Center declares its own checks, so its health is a property of the app rather than something the host guesses at.
This connection's own instance, via its GET /serverInfo. Sends no credential — an instance that requires auth even for this endpoint still counts as reachable.
