db3-atlassian-mcp

Lightweight MCP server for Jira, Confluence, and Bitbucket — read, create, and update from your AI IDE.

Install

Step 1: Get an API Token

Go to https://id.atlassian.com/manage-profile/security/api-tokens and create a new token.

Step 2: Create your .env file

mkdir -p ~/.db3-atlassian-mcp

cat > ~/.db3-atlassian-mcp/.env << EOF
JIRA_BASE_URL=https://yourcompany.atlassian.net
JIRA_USER=you@yourcompany.com
JIRA_API_KEY=your-api-token-here

# Optional: Bitbucket Cloud
BITBUCKET_WORKSPACE=your-workspace
BITBUCKET_USER=you@yourcompany.com
BITBUCKET_API_TOKEN=your-bitbucket-api-token

# Optional: Enable additional Bitbucket tool tiers
# ENABLE_BITBUCKET_PR_TOOLS=true
# ENABLE_BITBUCKET_ADMIN_TOOLS=true
EOF

Step 3: Add to your IDE's MCP config

Tip: If you skip Step 2, you can put your credentials directly in the env block below instead of using a .env file. Either approach works.

Kiro

You can ask Kiro to do this for you: "Add db3-atlassian-mcp to my MCP config using uvx with my Atlassian credentials"

Or manually open ~/.kiro/settings/mcp.json and add inside "mcpServers":

"db3.atlassian-mcp": {
  "command": "uvx",
  "args": ["db3-atlassian-mcp@latest"],
  "disabled": false,
  "autoApprove": [],
  "env": {
    "JIRA_BASE_URL": "https://yourcompany.atlassian.net",
    "JIRA_USER": "you@yourcompany.com",
    "JIRA_API_KEY": "your-api-token-here"
  }
}

The env block is optional if you already created a .env file in Step 2.

VS Code / Cursor / Windsurf

Add to .vscode/mcp.json in your workspace (or global settings):

{
  "mcpServers": {
    "db3.atlassian-mcp": {
      "command": "uvx",
      "args": ["db3-atlassian-mcp@latest"],
      "env": {
        "JIRA_BASE_URL": "https://yourcompany.atlassian.net",
        "JIRA_USER": "you@yourcompany.com",
        "JIRA_API_KEY": "your-api-token-here"
      }
    }
  }
}

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "db3.atlassian-mcp": {
      "command": "uvx",
      "args": ["db3-atlassian-mcp@latest"],
      "env": {
        "JIRA_BASE_URL": "https://yourcompany.atlassian.net",
        "JIRA_USER": "you@yourcompany.com",
        "JIRA_API_KEY": "your-api-token-here"
      }
    }
  }
}

Step 4: Restart your IDE

The MCP server will appear in your sidebar as db3.atlassian-mcp.

Once connected, ask Kiro something like "Read Jira ticket PROJECT-123" to verify it's working.

Configuration

Credentials

The server reads credentials from a .env file. It searches in this order:

1. ~/.db3-atlassian-mcp/.env (recommended)

2. .env in the current working directory

You can also pass credentials via your MCP config's env block (see Step 3 above).

Bitbucket Tool Tiers

By default, only core Bitbucket tools are enabled (repos, branches, PRs) to keep the tool count low. Enable additional tiers via environment variables:

Example with all tiers enabled:

"db3.atlassian-mcp": {
  "command": "uvx",
  "args": ["db3-atlassian-mcp@latest"],
  "env": {
    "JIRA_BASE_URL": "https://yourcompany.atlassian.net",
    "JIRA_USER": "you@yourcompany.com",
    "JIRA_API_KEY": "your-api-token-here",
    "ENABLE_BITBUCKET_PR_TOOLS": "true",
    "ENABLE_BITBUCKET_ADMIN_TOOLS": "true"
  }
}

Bitbucket Cloud

Bitbucket support is optional. Set these values only if you want Bitbucket tools:

BITBUCKET_WORKSPACE=your-workspace
BITBUCKET_USER=you@yourcompany.com
BITBUCKET_API_TOKEN=your-bitbucket-api-token

BITBUCKET_WORKSPACE lets tool calls omit the workspace argument. For bitbucket.org/your-workspace/..., use:

BITBUCKET_WORKSPACE=your-workspace

Use a Bitbucket Cloud API token scoped to the operations you need. Read-only tools need repository and pull request read scopes. Pipeline status tools need pipeline read scope. Creating pull requests or comments needs write access for pull requests.

Alternative: Install from Source

git clone https://github.com/db3net/db3-atlassian-mcp.git
cd db3-atlassian-mcp
bash install.sh

The installer prompts for your credentials, sets up a Python venv, validates the connection, and configures Kiro automatically.

Updating

If using uvx with @latest, it automatically pulls the newest version each time your IDE starts. If installed from source, run the installer again.

Version Pinning

Using @latest is convenient but means updates are applied automatically. For production or security-sensitive environments, pin to a specific version:

"args": ["db3-atlassian-mcp==1.1.0"]

This way you only get updates when you explicitly change the version number. Check PyPI for available versions.

Uninstall

rm -rf ~/.db3-atlassian-mcp

Then remove the "db3.atlassian-mcp" entry from your IDE's MCP config.

Troubleshooting

Server shows "connection failed" or ENOENT

• Make sure uv is installed: pip install uv or brew install uv

• Verify uvx is on your PATH: which uvx

• Check that Python 3.10+ is available: python3 --version

401 Unauthorized

• Verify your API token hasn't expired (Atlassian tokens can have expiration dates)

• Check that JIRA_USER is your email address, not your username

• Regenerate your token at https://id.atlassian.com/manage-profile/security/api-tokens

.env file not found

• Confirm the file exists: cat ~/.db3-atlassian-mcp/.env

• Make sure all three variables are set: JIRA_BASE_URL, JIRA_USER, JIRA_API_KEY

• The URL should not have a trailing slash

Tools not showing up

• Restart your IDE after adding the MCP config

• Check your IDE's MCP server logs for errors

• In Kiro: look at the MCP Servers panel in the sidebar and click reconnect
