JIRA MCP Server

A production-ready Model Context Protocol (MCP) server for JIRA integration. This server enables AI assistants to query JIRA issues and perform searches using natural language.

🎯 What This Demonstrates

MCP Concepts

• Tool Registration: Using @mcp.tool decorator

• Async Operations: Asynchronous tool functions

• Tool Documentation: Proper descriptions and type hints

• Server Lifecycle: Managing MCP sessions with FastAPI

• HTTP Streaming: Stateless HTTP-based MCP communication

Integration Patterns

• API Wrapper Design: Clean separation between MCP layer and API layer

• Error Handling: Robust error handling for API failures

• Configuration: Environment-based configuration

• Formatting: LLM-friendly Markdown output

• Authentication: Bearer token authentication

🚀 Quick Start

Prerequisites

• Python 3.11 or higher

• JIRA instance (Atlassian Cloud or self-hosted)

• JIRA API token with appropriate permissions

Installation

1. Navigate to this directory:

   cd 20_mcp/04-implementations/02-jira-server

2. Install dependencies:

   # Using uv (recommended)
   uv venv
   uv sync
   
   # Or using pip
   python -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate
   pip install -r requirements.txt

3. Configure environment:

   cp .env.example .env
   nano .env

Configuration

Create a .env file with your JIRA details:

# JIRA Configuration
JIRA_API_TOKEN=your_api_token_here
JIRA_BASE_URL=https://your-company.atlassian.net

# Optional: Custom SSL Certificate Path
# JIRA_CERT_PATH=/path/to/ca-bundle.crt

# Optional: Server Port
PORT=8000

Getting Your JIRA API Token

For Atlassian Cloud:

1. Log in to https://id.atlassian.com

2. Go to Security → API tokens

3. Click Create API token

4. Copy the token and add to .env

For Self-Hosted JIRA:

1. Log in to your JIRA instance

2. Go to Profile → Personal Access Tokens

3. Create a new token with appropriate scopes

4. Copy the token and add to .env

Running the Server

# Method 1: Using Python
python server.py

# Method 2: Using uvicorn directly
uvicorn server:app --host 0.0.0.0 --port 8000

# Method 3: Using uv
uv run server.py

Server will be available at:

• MCP Endpoint: http://localhost:8000/jira

• API Docs: http://localhost:8000/docs

📖 Usage

Available Tools

1. Get JIRA Issue

Fetch detailed information about a specific JIRA issue.

Example:

# Single issue
get_jira_issue("PROJECT-123")

# Multiple issues (comma-separated)
get_jira_issue("PROJECT-123,PROJECT-456")

Returns:

### Issue PROJECT-123: Fix login bug
**Status:** Open
#### Description:
Users cannot log in after password reset. Error occurs on login page...

2. Search JIRA Issues

Search for issues using JQL (JIRA Query Language).

Example JQL Queries:

# Open issues in a project
project = MYPROJECT AND status = Open

# High priority bugs assigned to you
assignee = currentUser() AND priority = High AND type = Bug

# Recently created issues
created >= -7d

# Search by text
summary ~ "performance" OR description ~ "performance"

# Complex query
project = MYPROJECT AND status IN (Open, "In Progress") AND assignee = currentUser() ORDER BY priority DESC

Example:

search_jira_issue("project = MYPROJECT AND status = Open")

Returns:

### Issue PROJECT-123: Fix login bug
**Status:** Open
#### Description:
Users cannot log in...

### Issue PROJECT-456: Update API documentation
**Status:** Open
#### Description:
API docs need updating...

🔌 Integration with AI Assistants

VS Code with GitHub Copilot

Add to your VS Code settings.json:

{
  "mcp.servers": {
    "jira": {
      "command": "python",
      "args": ["/path/to/20_mcp/04-implementations/02-jira-server/server.py"],
      "env": {
        "JIRA_API_TOKEN": "${env:JIRA_API_TOKEN}",
        "JIRA_BASE_URL": "https://your-company.atlassian.net"
      }
    }
  }
}

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "jira": {
      "command": "python",
      "args": ["/path/to/20_mcp/04-implementations/02-jira-server/server.py"],
      "env": {
        "JIRA_API_TOKEN": "your_token_here",
        "JIRA_BASE_URL": "https://your-company.atlassian.net"
      }
    }
  }
}

Using with MCP Client

from mcp.client import Client

async with Client("http://localhost:8000/jira") as client:
    # Get issue details
    result = await client.call_tool("get_jira_issue", {"issue_key": "PROJECT-123"})
    print(result)
    
    # Search issues
    result = await client.call_tool(
        "search_jira_issue", 
        {"query": "project = MYPROJECT AND status = Open"}
    )
    print(result)

🐳 Docker Deployment

FROM python:3.11-slim

WORKDIR /app

COPY pyproject.toml ./
RUN pip install uv && uv sync

COPY . .

CMD ["python", "server.py"]

Build and run:

docker build -t jira-mcp .
docker run -p 8000:8000 --env-file .env jira-mcp

🔒 Security Considerations

Authentication

• ✅ Uses Bearer token authentication (secure)

• ✅ Tokens stored in environment variables (not in code)

• ✅ Supports custom SSL certificates for enterprise

• ⚠️ Ensure .env is in .gitignore

Best Practices

• Use read-only JIRA tokens when possible

• Implement rate limiting for production

• Add request validation and sanitization

• Use HTTPS in production

• Implement proper logging (avoid logging tokens)

🐛 Troubleshooting

"Authentication failed"

• Verify JIRA_API_TOKEN is correct

• Check token hasn't expired

• Ensure token has appropriate permissions

"SSL Certificate verify failed"

• For self-hosted JIRA with custom certs, set JIRA_CERT_PATH

• For Atlassian Cloud, ensure JIRA_CERT_PATH is not set or set to None

"Issue not found"

• Verify issue key format (e.g., "PROJECT-123")

• Check you have permission to view the issue

• Ensure project key is correct

"JQL query failed"

• Validate JQL syntax at: https://your-jira-instance/secure/IssueNavigator.jspa

• Check field names are correct

• Ensure you have permission for the queried projects
