SSO login in a browser (Playwright); saves cookies for REST. If IdP redirects or automation block a session, use JIRA_PAT + PREFER_SSO_COOKIES=0 in mcp.json or delete the reported cookie file. When JIRA_PAT is set, REST prefers it unless PREFER_SSO_COOKIES and cookies override.

Run a JQL search and return issues (summary fields).

Get full issue JSON from Jira. Uses JIRA_REST_API_PREFIX (e.g. /rest/api/2 or /rest/api/3). If you see 401, set JIRA_PAT or run jira_login once.

Read a ticket as a compact object (summary, plain-text description, status, assignee, etc.).

Same as get_ticket — returns full issue JSON (alias for task-type issues).

Same as read_ticket — compact issue view (alias for task-type issues).

Return only summary and plain-text description for an issue.

Create an issue in a project. project is optional if the destination is unambiguous: set JIRA_DEFAULT_PROJECT in MCP env, pass boardName or boardId (Jira Software Agile boards), or omit when your account sees exactly one project across boards—otherwise the tool fails with a clear error listing boards (use list_boards). Description is plain text: v3 → ADF, v2 → string (JIRA_REST_API_PREFIX, JIRA_DESCRIPTION_FORMAT). Does not set sprint/backlog placement—use the UI or Agile REST for that.

Update issue fields (summary, description, labels, parent).

Delete an issue (requires permission).

List Jira projects. Uses /project/search on REST v3; on REST v2 uses GET /project (v2 has no project search endpoint).

List Jira Software boards (GET /rest/agile/1.0/board). Use names/ids with create_ticket when project is ambiguous. Returns 404 if Agile is disabled or your site has no Software boards—in that case pass project or JIRA_DEFAULT_PROJECT.

Assign an issue by Atlassian account ID.

List users assignable for a project.

Return all issue statuses from Jira.

Download an attachment from Confluence (CONFLUENCE_BASE_URL + CONFLUENCE_PAT or SSO cookies) and upload it to a Jira issue.

Download a file from a public URL and attach it to a Jira issue.
