Atlassian Data Center MCP

Note: This is a community-maintained project and is not affiliated with, endorsed by, or supported by Atlassian. Use at your own discretion.

This project provides a Model Context Protocol (MCP) integration for Atlassian Data Center products, including Jira, Confluence, and Bitbucket.

Quick Setup

Each package ships an interactive setup subcommand that stores your credentials in the most secure place available on your OS. Run it once per product:

npx @atlassian-dc-mcp/jira setup
npx @atlassian-dc-mcp/confluence setup
npx @atlassian-dc-mcp/bitbucket setup

The setup CLI prompts for host, API base path, default page size, and API token. Before saving, it validates obvious input mistakes and performs a timed authenticated request to the selected Atlassian product, so a bad host, base path, or token is caught during setup.

CLI flags and non-interactive mode

Setup accepts flags so you can prefill values or skip prompts entirely (useful for scripted bootstrap, CI, or remote sessions). Run npx @atlassian-dc-mcp/<product> setup --help for the full list.

In interactive mode, any flag you pass prefills its prompt (so e.g. --host skips the host prompt but still asks for the rest). In --non-interactive mode, setup resolves anything missing from existing configuration (process env, ~/.atlassian-dc-mcp/<product>.env, or macOS Keychain) and exits non-zero if a host (or full-URL --api-base-path) and token cannot be found. An existing token is reused when --token is omitted.

# Scripted, no prompts, write everything from flags
npx @atlassian-dc-mcp/jira setup --non-interactive \
  --host jira.example.com \
  --token "$JIRA_TOKEN"

# Re-validate the existing token without re-entering it
npx @atlassian-dc-mcp/jira setup --non-interactive --host jira.example.com

Credential validation behaves differently between modes: interactive mode offers retry/save-anyway prompts on failure, while --non-interactive exits with code 1 on the first validation failure so it can be used as a CI gate.

Token storage:

• macOS — written to the login Keychain via /usr/bin/security (service atlassian-dc-mcp, account <product>-token).
• Linux — written to ~/.atlassian-dc-mcp/<product>.env with POSIX mode 0600 (read/write for your user only; other local user accounts cannot read it).
• Windows — written to %USERPROFILE%\.atlassian-dc-mcp\<product>.env. Node passes the mode bits but Windows ignores them, so the file inherits the ACL of your user profile directory — typically readable only by your user, SYSTEM, and Administrators.

Non-secret fields (host, API base path, default page size) are always written to the home file — ~/.atlassian-dc-mcp/<product>.env on macOS/Linux, %USERPROFILE%\.atlassian-dc-mcp\<product>.env on Windows. After a successful Keychain write, the token line is cleared from the home file so there is never a second copy in a less-secure place.

Once setup has run, the MCP servers can boot with no environment variables at all:

{
  "mcpServers": {
    "atlassian-jira-dc": { "command": "npx", "args": ["-y", "@atlassian-dc-mcp/jira"] },
    "atlassian-confluence-dc": { "command": "npx", "args": ["-y", "@atlassian-dc-mcp/confluence"] },
    "atlassian-bitbucket-dc": { "command": "npx", "args": ["-y", "@atlassian-dc-mcp/bitbucket"] }
  }
}

You can still pass credentials via environment variables or ATLASSIAN_DC_MCP_CONFIG_FILE as shown in the sections below — they take precedence over values saved by setup.

Configuration Sources & Precedence

At startup, each MCP server resolves each config key by walking sources in this order and taking the first non-empty value:

Notes:

• Process env wins over everything, so you can always override a stored credential for one session.
• ATLASSIAN_DC_MCP_CONFIG_FILE must be an absolute path; if set and missing, the server fails fast.
• Keychain reads are cached at init (one execFileSync per product-token), so tool calls never shell out.
• If a higher-priority source shadows the value setup is about to save, setup prints a warning naming the env var so you can unset it.
• Atlassian API requests time out after 30 seconds by default. Set ATLASSIAN_DC_MCP_REQUEST_TIMEOUT_MS to a positive millisecond value to override it.

Claude Desktop Configuration

Official Anthropic quick start guide

To use these MCP connectors with Claude Desktop, add the following to your Claude Desktop configuration.

Set *_HOST variables only to domain + port without protocol (e.g., your-instance.atlassian.net). The https protocol is assumed.

Alternatively, you can use *_API_BASE_PATH variables instead of *_HOST to specify the complete API base URL including protocol (e.g., https://your-instance.atlassian.net/rest). Note that the /api/latest/ part is static and added automatically in the code, so you don't need to include it in the *_API_BASE_PATH values.

You can leave only the services you need in the configuration.

macOS:

~/Library/Application Support/Claude/claude_desktop_config.json

Windows:

%APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "atlassian-jira-dc": {
      "command": "npx",
      "args": ["-y", "@atlassian-dc-mcp/jira"],
      "env": {
        "JIRA_HOST": "your-jira-host",

      }
    },
    "atlassian-confluence-dc": {

      "env": {
        "CONFLUENCE_HOST": "your-confluence-host",
        "CONFLUENCE_API_TOKEN": "your-token"
      }
    },
    "atlassian-bitbucket-dc": {
      "command": "npx",
      "args": ["-y", "@atlassian-dc-mcp/bitbucket"],
      "env": {

        "BITBUCKET_API_TOKEN": "your-token"
      }
    }
  }
}

You can also use the alternative API base path configuration:

{
  "mcpServers": {
    "atlassian-jira-dc": {
      "command": "npx",
      "args": ["-y", "@atlassian-dc-mcp/jira"],
      "env": {
        "JIRA_API_BASE_PATH": "https://your-jira-host/rest",
        "JIRA_API_TOKEN": "your-token"
      }
    },
    "atlassian-confluence-dc": {
      "command": "npx",
      "args": ["-y", "@atlassian-dc-mcp/confluence"],
      "env": {
        "CONFLUENCE_API_BASE_PATH": "https://your-confluence-host/rest",
        "CONFLUENCE_API_TOKEN": "your-token"
      }
    },
    "atlassian-bitbucket-dc": {
      "command": "npx",
      "args": ["-y", "@atlassian-dc-mcp/bitbucket"],
      "env": {
        "BITBUCKET_API_BASE_PATH": "https://your-bitbucket-host/rest",
        "BITBUCKET_API_TOKEN": "your-token"
      }
    }
  }
}

Shared External Config File

If you want multiple MCP hosts or tools on one machine to reuse the same Atlassian credentials, put the existing JIRA_*, CONFLUENCE_*, and BITBUCKET_* variables into one dotenv-style file and point each MCP server at it with ATLASSIAN_DC_MCP_CONFIG_FILE.

The path must be absolute. Direct environment variables still override values from the shared file.

Example shared file:

JIRA_HOST=your-jira-host
JIRA_API_TOKEN=your-jira-token
JIRA_DEFAULT_PAGE_SIZE=50

CONFLUENCE_HOST=your-confluence-host
CONFLUENCE_API_TOKEN=your-confluence-token

BITBUCKET_HOST=your-bitbucket-host
BITBUCKET_API_TOKEN=your-bitbucket-token
BITBUCKET_DEFAULT_PAGE_SIZE=50

Claude Desktop example using one shared file:

{
  "mcpServers": {
    "atlassian-jira-dc": {
      "command": "npx",
      "args": ["-y", "@atlassian-dc-mcp/jira"],
      "env": {
        "ATLASSIAN_DC_MCP_CONFIG_FILE": "/Users/your-user/.config/atlassian-dc-mcp.env"
      }
    },
    "atlassian-confluence-dc": {
      "command": "npx",
      "args": ["-y", "@atlassian-dc-mcp/confluence"],
      "env": {
        "ATLASSIAN_DC_MCP_CONFIG_FILE": "/Users/your-user/.config/atlassian-dc-mcp.env"
      }
    },
    "atlassian-bitbucket-dc": {
      "command": "npx",
      "args": ["-y", "@atlassian-dc-mcp/bitbucket"],
      "env": {
        "ATLASSIAN_DC_MCP_CONFIG_FILE": "/Users/your-user/.config/atlassian-dc-mcp.env"
      }
    }
  }
}
