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

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": "your.email@example.com",
      "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

Required environment variables:

JIRA_URL

https://yourorg.atlassian.net

JIRA_EMAIL

JIRA_API_TOKEN

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

MCP Tools Reference

When the

mcp-atlassian

jira_search

project = PROJ AND status = "In Progress"

jira_get_issue

PROJ-1234

jira_create_issue

jira_update_issue

jira_transition_issue

jira_add_comment

jira_get_sprint_issues

jira_create_issue_link

jira_get_issue_development_info

Tip: Always call

jira_get_transitions

before transitioning — transition IDs vary per project workflow.

Direct REST API Reference

Fetch a Ticket

curl -s -u "$JIRA_EMAIL:$JIRA_API_TOKEN" \
  -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

curl -s -u "$JIRA_EMAIL:$JIRA_API_TOKEN" \
  -H "Content-Type: application/json" \
  "$JIRA_URL/rest/api/3/issue/PROJ-1234?fields=comment" | jq '.fields.comment.comments[] | {
    author: .author.displayName,
    created: .created[:10],
    body: .body
  }'

Add a Comment

curl -s -X POST -u "$JIRA_EMAIL:$JIRA_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "body": {
      "version": 1,
      "type": "doc",
      "content": [{
        "type": "paragraph",
        "content": [{"type": "text", "text": "Your comment here"}]
      }]
    }
  }' \
  "$JIRA_URL/rest/api/3/issue/PROJ-1234/comment"

Transition a Ticket

# 1. Get available transitions
curl -s -u "$JIRA_EMAIL:$JIRA_API_TOKEN" \
  "$JIRA_URL/rest/api/3/issue/PROJ-1234/transitions" | jq '.transitions[] | {id, name: .name}'

# 2. Execute transition (replace TRANSITION_ID)
curl -s -X POST -u "$JIRA_EMAIL:$JIRA_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"transition": {"id": "TRANSITION_ID"}}' \
  "$JIRA_URL/rest/api/3/issue/PROJ-1234/transitions"

Search with JQL

curl -s -G -u "$JIRA_EMAIL:$JIRA_API_TOKEN" \
  --data-urlencode "jql=project = PROJ AND status = 'In Progress'" \
  "$JIRA_URL/rest/api/3/search"

Analyzing a Ticket

When retrieving a ticket for development or test automation, extract:

1. Testable Requirements

• Functional requirements — What the feature does
• Acceptance criteria — Conditions that must be met
• Testable behaviors — Specific actions and expected outcomes
• User roles — Who uses this feature and their permissions
• Data requirements — What data is needed
• Integration points — APIs, services, or systems involved

2. Test Types Needed

• Unit tests — Individual functions and utilities
• Integration tests — API endpoints and service interactions
• E2E tests — User-facing UI flows
• API tests — Endpoint contracts and error handling

3. Edge Cases & Error Scenarios

• Invalid inputs (empty, too long, special characters)
• Unauthorized access
• Network failures or timeouts
• Concurrent users or race conditions
• Boundary conditions
• Missing or null data
• State transitions (back navigation, refresh, etc.)

4. Structured Analysis Output

Security Guidelines

• Never hardcode Jira API tokens in source code or skill files
• Always use environment variables or a secrets manager
• Add

  .env

  to

  .gitignore

  in every project
• Rotate tokens immediately if exposed in git history
• Use least-privilege API tokens scoped to required projects
• Validate that credentials are set before making API calls — fail fast with a clear message

Best Practices

• Update Jira as you go, not all at once at the end
• Keep comments concise but informative
• Link rather than copy — point to PRs, test reports, and dashboards
• Use @mentions if you need input from others
• Check linked issues to understand full feature scope before starting
• If acceptance criteria are vague, ask for clarification before writing code
