jira-context-mcp

jira-context-mcp is a production-focused MCP server that fetches structured Jira issue context from a Jira URL. It is designed for coding agents like Codex and Claude Code so they can quickly understand issue intent and implementation context.

What This Server Does

• Exposes one MCP tool: get_jira_issue_from_url

• Validates that the input URL belongs to your JIRA_BASE_URL

• Extracts a Jira issue key from multiple Jira URL shapes

• Calls Jira Cloud REST API:

  • GET /rest/api/3/issue/{issueIdOrKey}?expand=names,renderedFields

• Converts Jira rich text (Atlassian Document Format) into plain text

• Returns concise, agent-friendly structured issue context

Supported Jira Issue Types

This server is issue-type agnostic. It works for any Jira issue type, including:

• Bug

• Feature request

• Task

• Story

• Epic

• Requirement

• Improvement

• Support ticket

• Custom issue types

Required Environment Variables

• JIRA_EMAIL: Jira account email

• JIRA_API_TOKEN: Jira API token

• JIRA_BASE_URL: Jira Cloud tenant URL (example: https://your-domain.atlassian.net)

Security Notes

• Keep JIRA_API_TOKEN secret. Never commit it to source control.

• Use least-privilege Jira access for the account tied to the token.

• This server only fetches issue data and attachment metadata; it does not download attachment files.

• URL validation rejects URLs outside your configured JIRA_BASE_URL.
