jira_get

Read any Jira data. Returns TOON format by default (30-60% fewer tokens than JSON). **IMPORTANT - Cost Optimization:** - ALWAYS use `jq` param to filter response fields. Unfiltered responses are very expensive! - Use `maxResults` query param to restrict result count (e.g., `maxResults: "5"`) - If unsure about available fields, first fetch ONE item with `maxResults: "1"` and NO jq filter to explore the schema, then use jq in subsequent calls **Schema Discovery Pattern:** 1. First call: `path: "/rest/api/3/search/jql", queryParams: {"maxResults": "1", "jql": "project=PROJ"}` (no jq) - explore available fields 2. Then use: `jq: "issues[*].{key: key, summary: fields.summary, status: fields.status.name}"` - extract only what you need **Output format:** TOON (default, token-efficient) or JSON (`outputFormat: "json"`) **Common paths:** - `/rest/api/3/project` - list all projects - `/rest/api/3/project/{projectKeyOrId}` - get project details - `/rest/api/3/search/jql` - search issues with JQL (use `jql` query param). NOTE: `/rest/api/3/search` is deprecated! - `/rest/api/3/issue/{issueIdOrKey}` - get issue details - `/rest/api/3/issue/{issueIdOrKey}/comment` - list issue comments - `/rest/api/3/issue/{issueIdOrKey}/worklog` - list issue worklogs - `/rest/api/3/issue/{issueIdOrKey}/transitions` - get available transitions - `/rest/api/3/user/search` - search users (use `query` param) - `/rest/api/3/status` - list all statuses - `/rest/api/3/issuetype` - list issue types - `/rest/api/3/priority` - list priorities **JQ examples:** `issues[*].key`, `issues[0]`, `issues[*].{key: key, summary: fields.summary}` **Example JQL queries:** `project=PROJ`, `assignee=currentUser()`, `status="In Progress"`, `created >= -7d` API reference: https://developer.atlassian.com/cloud/jira/platform/rest/v3/

jira_post

Create Jira resources. Returns TOON format by default (token-efficient). **IMPORTANT - Cost Optimization:** - Use `jq` param to extract only needed fields from response (e.g., `jq: "{key: key, id: id}"`) - Unfiltered responses include all metadata and are expensive! **Output format:** TOON (default) or JSON (`outputFormat: "json"`) **Common operations:** 1. **Create issue:** `/rest/api/3/issue` body: `{"fields": {"project": {"key": "PROJ"}, "summary": "Issue title", "issuetype": {"name": "Task"}, "description": {"type": "doc", "version": 1, "content": [{"type": "paragraph", "content": [{"type": "text", "text": "Description"}]}]}}}` 2. **Add comment:** `/rest/api/3/issue/{issueIdOrKey}/comment` body: `{"body": {"type": "doc", "version": 1, "content": [{"type": "paragraph", "content": [{"type": "text", "text": "Comment text"}]}]}}` 3. **Add worklog:** `/rest/api/3/issue/{issueIdOrKey}/worklog` body: `{"timeSpentSeconds": 3600, "comment": {"type": "doc", "version": 1, "content": [{"type": "paragraph", "content": [{"type": "text", "text": "Work done"}]}]}}` 4. **Transition issue:** `/rest/api/3/issue/{issueIdOrKey}/transitions` body: `{"transition": {"id": "31"}}` 5. **Add attachment:** `/rest/api/3/issue/{issueIdOrKey}/attachments` Note: Requires multipart form data (complex - use Jira UI for attachments) API reference: https://developer.atlassian.com/cloud/jira/platform/rest/v3/

jira_put

Replace Jira resources (full update). Returns TOON format by default. **IMPORTANT - Cost Optimization:** Use `jq` param to extract only needed fields from response **Output format:** TOON (default) or JSON (`outputFormat: "json"`) **Common operations:** 1. **Update issue (full):** `/rest/api/3/issue/{issueIdOrKey}` body: `{"fields": {"summary": "New title", "description": {...}, "assignee": {"accountId": "..."}}}` 2. **Update project:** `/rest/api/3/project/{projectIdOrKey}` body: `{"name": "New Project Name", "description": "Updated description"}` 3. **Set issue property:** `/rest/api/3/issue/{issueIdOrKey}/properties/{propertyKey}` body: `{"value": "property value"}` Note: PUT replaces the entire resource. For partial updates, prefer PATCH. API reference: https://developer.atlassian.com/cloud/jira/platform/rest/v3/

jira_patch

Partially update Jira resources.

jira_delete

Delete Jira resources. Returns TOON format by default. **Output format:** TOON (default) or JSON (`outputFormat: "json"`) **Common operations:** 1. **Delete issue:** `/rest/api/3/issue/{issueIdOrKey}` Query param: `deleteSubtasks=true` to delete subtasks 2. **Delete comment:** `/rest/api/3/issue/{issueIdOrKey}/comment/{commentId}` 3. **Delete worklog:** `/rest/api/3/issue/{issueIdOrKey}/worklog/{worklogId}` 4. **Delete attachment:** `/rest/api/3/attachment/{attachmentId}` 5. **Remove watcher:** `/rest/api/3/issue/{issueIdOrKey}/watchers` Query param: `accountId={accountId}` Note: Most DELETE endpoints return 204 No Content on success.
