Transform how you work with Bitbucket by connecting Claude, Cursor AI, and other AI assistants directly to your repositories, pull requests, and code. Get instant insights, automate code reviews, and streamline your development workflow.

What You Can Do

• Ask AI about your code: "What's the latest commit in my main repository?"
• Get PR insights: "Show me all open pull requests that need review"
• Search your codebase: "Find all JavaScript files that use the authentication function"
• Review code changes: "Compare the differences between my feature branch and main"
• Manage pull requests: "Create a PR for my new-feature branch"
• Automate workflows: "Add a comment to PR #123 with the test results"

Perfect For

• Developers who want AI assistance with code reviews and repository management
• Team Leads needing quick insights into project status and pull request activity
• DevOps Engineers automating repository workflows and branch management
• Anyone who wants to interact with Bitbucket using natural language

Quick Start

Get up and running in 2 minutes:

1. Get Your Bitbucket Credentials

IMPORTANT: Bitbucket App Passwords are being deprecated and will be removed by June 2026. We recommend using Scoped API Tokens for new setups.

Option A: Scoped API Token (Recommended - Future-Proof)

Bitbucket is deprecating app passwords. Use the new scoped API tokens instead:

1. Go to Atlassian API Tokens
2. Click "Create API token with scopes"
3. Select "Bitbucket" as the product
4. Choose the appropriate scopes:
   • For read-only access: repository, workspace
   • For full functionality: repository, workspace, pullrequest
5. Copy the generated token (starts with ATATT)
6. Use with your Atlassian email as the username

Option B: App Password (Legacy - Will be deprecated)

Generate a Bitbucket App Password (legacy method):

1. Go to Bitbucket App Passwords
2. Click "Create app password"
3. Give it a name like "AI Assistant"
4. Select these permissions:
   • Workspaces: Read
   • Repositories: Read (and Write if you want AI to create PRs/comments)
   • Pull Requests: Read (and Write for PR management)

2. Try It Instantly

# Set your credentials (choose one method)

# Method 1: Scoped API Token (recommended - future-proof)
export ATLASSIAN_USER_EMAIL="your.email@company.com"
export ATLASSIAN_API_TOKEN="your_scoped_api_token"  # Token starting with ATATT

# OR Method 2: Legacy App Password (will be deprecated June 2026)
export ATLASSIAN_BITBUCKET_USERNAME="your_username"
export ATLASSIAN_BITBUCKET_APP_PASSWORD="your_app_password"

# List your workspaces
npx -y @aashari/mcp-server-atlassian-bitbucket get --path "/workspaces"

# List repositories in a workspace
npx -y @aashari/mcp-server-atlassian-bitbucket get --path "/repositories/your-workspace"

# Get pull requests for a repository
npx -y @aashari/mcp-server-atlassian-bitbucket get --path "/repositories/your-workspace/your-repo/pullrequests"

# Get repository details with JMESPath filtering
npx -y @aashari/mcp-server-atlassian-bitbucket get --path "/repositories/your-workspace/your-repo" --jq "{name: name, language: language}"

Connect to AI Assistants

For Claude Desktop Users

Add this to your Claude configuration file (~/.claude/claude_desktop_config.json):

Option 1: Scoped API Token (recommended - future-proof)

{
  "mcpServers": {
    "bitbucket": {
      "command": "npx",
      "args": ["-y", "@aashari/mcp-server-atlassian-bitbucket"],
      "env": {
        "ATLASSIAN_USER_EMAIL": "your.email@company.com",
        "ATLASSIAN_API_TOKEN": "your_scoped_api_token"
      }
    }
  }
}

Option 2: Legacy App Password (will be deprecated June 2026)

{
  "mcpServers": {
    "bitbucket": {
      "command": "npx",
      "args": ["-y", "@aashari/mcp-server-atlassian-bitbucket"],
      "env": {
        "ATLASSIAN_BITBUCKET_USERNAME": "your_username",
        "ATLASSIAN_BITBUCKET_APP_PASSWORD": "your_app_password"
      }
    }
  }
}

Restart Claude Desktop, and you'll see the bitbucket server in the status bar.

For Other AI Assistants

Most AI assistants support MCP. Install the server globally:

npm install -g @aashari/mcp-server-atlassian-bitbucket

Then configure your AI assistant to use the MCP server with STDIO transport.

Alternative: Configuration File

Create ~/.mcp/configs.json for system-wide configuration:

Option 1: Scoped API Token (recommended - future-proof)

{
  "bitbucket": {
    "environments": {
      "ATLASSIAN_USER_EMAIL": "your.email@company.com",
      "ATLASSIAN_API_TOKEN": "your_scoped_api_token",
      "BITBUCKET_DEFAULT_WORKSPACE": "your_main_workspace"
    }
  }
}

Option 2: Legacy App Password (will be deprecated June 2026)

{
  "bitbucket": {
    "environments": {
      "ATLASSIAN_BITBUCKET_USERNAME": "your_username",
      "ATLASSIAN_BITBUCKET_APP_PASSWORD": "your_app_password",
      "BITBUCKET_DEFAULT_WORKSPACE": "your_main_workspace"
    }
  }
}

Alternative config keys: The system also accepts "atlassian-bitbucket", "@aashari/mcp-server-atlassian-bitbucket", or "mcp-server-atlassian-bitbucket" instead of "bitbucket".

Troubleshooting

"Authentication failed" or "403 Forbidden"

1. Choose the right authentication method:

   • Standard Atlassian method: Use your Atlassian account email + API token (works with any Atlassian service)
   • Bitbucket-specific method: Use your Bitbucket username + App password (Bitbucket only)

2. For Scoped API Tokens (recommended):

   • Go to Atlassian API Tokens
   • Make sure your token is still active and has the right scopes
   • Required scopes: repository, workspace (add pullrequest for PR management)

3. For Bitbucket App Passwords (legacy):

   • Go to Bitbucket App Passwords
   • Make sure your app password has the right permissions

4. Verify your credentials:

   npx -y @aashari/mcp-server-atlassian-bitbucket get --path "/workspaces"

"Resource not found" or "404"

1. Check the API path:

   • Paths are case-sensitive
   • Use workspace slug (from URL), not display name
   • Example: If your repo URL is https://bitbucket.org/myteam/my-repo, use myteam and my-repo

2. Verify the resource exists:

   # List workspaces to find the correct slug
   npx -y @aashari/mcp-server-atlassian-bitbucket get --path "/workspaces"
