## About

# JIRA MCP Server

A Model Context Protocol (MCP) server implementation that provides access to JIRA data with relationship tracking, optimized data payloads, and data cleaning for AI context windows.

ℹ️ There is a separate MCP server [for Confluence](https://github.com/cosmix/confluence-mcp)

---

## Jira Cloud & Jira Server (Data Center) Support

This MCP server supports both **Jira Cloud** and **Jira Server (Data Center)** instances. You can select which type to use by setting the `JIRA_TYPE` environment variable:

- `cloud` (default): For Jira Cloud (Atlassian-hosted)
- `server`: For Jira Server/Data Center (self-hosted)

The server will automatically use the correct API version and authentication method for the selected type.

---

## Features

- Search JIRA issues using JQL (maximum 50 results per request)
- Retrieve epic children with comment history and optimized payloads (maximum 100 issues per request)
- Get detailed issue information including comments and related issues
- Create, update, and manage JIRA issues
- Add comments to issues
- Extract issue mentions from Atlassian Document Format
- Track issue relationships (mentions, links, parent/child, epics)
- Clean and transform rich JIRA content for AI context efficiency
- Support for file attachments with secure multipart upload handling
- **Supports both Jira Cloud and Jira Server (Data Center) APIs**

## Prerequisites

- [Bun](https://bun.sh) (v1.0.0 or higher)
- JIRA account with API access

## Environment Variables

```bash
JIRA_API_TOKEN=your_api_token            # API token for Cloud, PAT or password for Server/DC
JIRA_BASE_URL=your_jira_instance_url     # e.g., https://your-domain.atlassian.net

JIRA_TYPE=cloud                          # 'cloud' or 'server' (optional, defaults to 'cloud')
JIRA_AUTH_TYPE=basic                     # 'basic' or 'bearer' (optional, defaults to 'basic')
```

### Authentication Methods

- **Jira Cloud**: Use API tokens with Basic authentication
  - Create an API token at: 
  - Set `JIRA_AUTH_TYPE=basic` (default)
  
- **Jira Server/Data Center**:
  - **Basic Auth**: Use username/password or API tokens
    - Set `JIRA_AUTH_TYPE=basic` (default)
  - **Bearer Auth**: Use Personal Access Tokens (PATs) - available in Data Center 8.14.0+
    - Create a PAT in your profile settings
    - Set `JIRA_AUTH_TYPE=bearer`
    - Use the PAT as your `JIRA_API_TOKEN`

## Installation & Setup

### 1. Clone the repository

```bash
git clone [repository-url]
cd jira-mcp
```

### 2. Install dependencies and build

```bash
bun install
bun run build
```

### 3. Configure the MCP server

Edit the appropriate configuration file:

**macOS:**

- Cline: `~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json`
- Claude Desktop: `~/Library/Application Support/Claude/claude_desktop_config.json`

**Windows:**

- Cline: `%APPDATA%\Code\User\globalStorage\saoudrizwan.claude-dev\settings\cline_mcp_settings.json`
- Claude Desktop: `%APPDATA%\Claude Desktop\claude_desktop_config.json`

**Linux:**

- Cline: `~/.config/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json`
- Claude Desktop: _sadly doesn't exist yet_

Add the following configuration under the `mcpServers` object:

```json
{
  "mcpServers": {
    "jira": {
      "command": "node",
      "args": ["/absolute/path/to/jira-mcp/build/index.js"],
      "env": {
        "JIRA_API_TOKEN": "your_api_token",
        "JIRA_BASE_URL": "your_jira_instance_url",
        "JIRA_USER_EMAIL": "your_email",
        "JIRA_TYPE": "cloud",
        "JIRA_AUTH_TYPE": "basic"
      }
    }
  }
}
```

### 4. Restart the MCP server

Within Cline's MCP settings, restart the MCP server. Restart Claude Desktop to load the new MCP server.

## Development

```bash
bun test
```

Watch mode for development:
