Set it up in Melso

1In Melso, open Settings → Agent Apps and hit Connect on Jira.
2Finish the OAUTH2 / S2S_OAUTH2 sign-in in the window that opens. Melso stores the connection, not your credentials.

Tools Jira exposes

JIRA_ADD_ATTACHMENT

Add Attachment

Uploads and attaches a file to a Jira issue.

JIRA_ADD_COMMENT

Add Comment

Adds a comment using Atlassian Document Format (ADF) for rich text to an existing Jira issue.

JIRA_ADD_USERS_TO_PROJECT_ROLE

Add Users to Project Role

Adds users and optionally groups to a project role.

JIRA_ADD_USER_TO_GROUP

Add User to Group

Adds a user to a Jira group.

JIRA_ADD_WATCHER_TO_ISSUE

Add Watcher to Issue

Adds a user to an issue's watcher list by account ID. Requires the authenticated user to have permission to view the issue and manage watchers; insufficient permissions may result in silent failure or an error response.

JIRA_ADD_WORKLOG

Add Worklog

Tool to add a worklog entry to a Jira issue. Use when logging time spent on an issue.

JIRA_ANALYSE_EXPRESSION

Analyse Jira Expression

Analyses Jira expressions for syntax validation, type checking, and complexity analysis. Use when you need to validate Jira expression syntax before using it in automation rules, custom fields, or workflows.

JIRA_ASSIGN_ISSUE

Assign Issue

Assigns a Jira issue to a user, default assignee, or unassigns; supports email/name lookup.

Events your agent can react to

JIRA_NEW_ISSUE_TRIGGER

New Issue

Fires when a new issue is created in the Jira project you configure. Only issues created in that project produce an event.

JIRA_NEW_PROJECT_TRIGGER

New Project

Triggered when a new project is added in Jira

JIRA_UPDATED_ISSUE_TRIGGER

Updated Issue

Fires when an existing issue is changed in the Jira project you configure — for example its status, assignee, or any other field on the issue is updated. Only issues in that project produce an event. It does not fire on comment activity: adding, editing, or deleting a comment on an issue will not produce an event from this trigger.
