Jira Integration Skill

Retrieve, analyze, and update Jira tickets directly from your AI coding workflow. Supports both MCP-based (recommended) and direct REST API approaches.

When to Activate

• Fetching a Jira ticket to understand requirements
• Extracting testable acceptance criteria from a ticket
• Adding progress comments to a Jira issue
• Transitioning a ticket status (To Do → In Progress → Done)
• Linking merge requests or branches to a Jira issue
• Searching for issues by JQL query

Prerequisites

Option A: MCP Server (Recommended)

Install the mcp-atlassian MCP server. This exposes Jira tools directly to your AI agent.

Requirements:

• Python 3.10+
• uvx (from uv), installed via your package manager or the official uv installation documentation

Add to your MCP config (e.g., ~/.claude.json → mcpServers):

{
  "jira": {
    "command": "uvx",
    "args": ["mcp-atlassian==0.21.0"],
    "env": {
      "JIRA_URL": "https://YOUR_ORG.atlassian.net",
      "JIRA_EMAIL": "[email protected]",
      "JIRA_API_TOKEN": "your-api-token"
    },
    "description": "Jira issue tracking — search, create, update, comment, transition"
  }
}

Security: Never hardcode secrets. Prefer setting JIRA_URL, JIRA_EMAIL, and JIRA_API_TOKEN in your system environment (or a secrets manager). Only use the MCP env block for local, uncommitted config files.

To get a Jira API token:

1. Go to https://id.atlassian.com/manage-profile/security/api-tokens
2. Click Create API token
3. Copy the token — store it in your environment, never in source code

Option B: Direct REST API

If MCP is not available, use the Jira REST API v3 directly via curl or a helper script.

Required environment variables:

Store these in your shell environment, secrets manager, or an untracked local env file. Do not commit them to the repo.

For direct curl examples, keep credentials out of command-line arguments by passing the Jira user config on stdin:

jira_curl() {
  printf 'user = "%s:%s"\n' "$JIRA_EMAIL" "$JIRA_API_TOKEN" |
    curl -s -K - "$@"
}

MCP Tools Reference

When the mcp-atlassian MCP server is configured, these tools are available:

Tip: Always call jira_get_transitions before transitioning — transition IDs vary per project workflow.

Direct REST API Reference

Fetch a Ticket

jira_curl \
  -H "Content-Type: application/json" \
  "$JIRA_URL/rest/api/3/issue/PROJ-1234" | jq '{
    key: .key,
    summary: .fields.summary,
    status: .fields.status.name,
    priority: .fields.priority.name,
    type: .fields.issuetype.name,
    assignee: .fields.assignee.displayName,
    labels: .fields.labels,
    description: .fields.description
  }'

Fetch Comments

jira_curl \
  -H "Content-Type: application/json" \
  "$JIRA_URL/rest/api/3/issue/PROJ-1234?fields=comment" | jq '.fields.comment.comments[] | {
    author: .author.displayName,
