Installation

Using npx (Recommended)

The easiest way to use this MCP server is directly with npx:

{
  "mcpServers": {
    "bitbucket": {
      "command": "npx",
      "args": [
        "-y",
        "@nexus2520/bitbucket-mcp-server"
      ],
      "env": {
        "BITBUCKET_USERNAME": "your-username",
        "BITBUCKET_APP_PASSWORD": "your-app-password"
      }
    }
  }
}

For Bitbucket Server:

{
  "mcpServers": {
    "bitbucket": {
      "command": "npx",
      "args": [
        "-y",
        "@nexus2520/bitbucket-mcp-server"
      ],
      "env": {
        "BITBUCKET_USERNAME": "your.email@company.com",
        "BITBUCKET_TOKEN": "your-http-access-token",
        "BITBUCKET_BASE_URL": "https://bitbucket.yourcompany.com"
      }
    }
  }
}

From Source

  1. Clone or download this repository

  2. Install dependencies:

    npm install

  3. Build the TypeScript code:

    npm run build

Authentication Setup

This server uses Bitbucket App Passwords for authentication.

Creating an App Password

  1. Log in to your Bitbucket account

  2. Navigate to: https://bitbucket.org/account/settings/app-passwords/

  3. Click "Create app password"

  4. Give it a descriptive label (e.g., "MCP Server")

  5. Select the following permissions:

    • Account: Read

    • Repositories: Read, Write

    • Pull requests: Read, Write

  6. Click "Create"

  7. Important: Copy the generated password immediately (you won't be able to see it again!)

Running the Setup Script

node scripts/setup-auth.js

This will guide you through the authentication setup process.

Configuration

Add the server to your MCP settings file (usually located at ~/.vscode-server/data/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json):

{
  "mcpServers": {
    "bitbucket": {
      "command": "node",
      "args": ["/absolute/path/to/bitbucket-mcp-server/build/index.js"],
      "env": {
        "BITBUCKET_USERNAME": "your-username",
        "BITBUCKET_APP_PASSWORD": "your-app-password"
      }
    }
  }
}

Replace:

  • /absolute/path/to/bitbucket-mcp-server with the actual path to this directory

  • your-username with your Bitbucket username (not email)

  • your-app-password with the app password you created

For Bitbucket Server, use:

{
  "mcpServers": {
    "bitbucket": {
      "command": "node",
      "args": ["/absolute/path/to/bitbucket-mcp-server/build/index.js"],
      "env": {
        "BITBUCKET_USERNAME": "your.email@company.com",
        "BITBUCKET_TOKEN": "your-http-access-token",
        "BITBUCKET_BASE_URL": "https://bitbucket.yourcompany.com"
      }
    }
  }
}

Important for Bitbucket Server users:

  • Use your full email address as the username (e.g., "john.doe@company.com")

  • This is required for approval/review actions to work correctly

      ]
    }
  ],
  "total_count": 15,
  "start": 0,
  "limit": 50,
  "has_more": false
}

Note: This tool currently only works with Bitbucket Server. Bitbucket Cloud support is planned for a future release.

List Pull Requests

{
  "tool": "list_pull_requests",
  "arguments": {
    "workspace": "PROJ",  // Required - your project key
    "repository": "my-repo",
    "state": "OPEN",  // Optional: OPEN, MERGED, DECLINED, ALL (default: OPEN)
    "author": "username",  // Optional: filter by author (see note below)
    "limit": 25,  // Optional: max results per page (default: 25)
    "start": 0  // Optional: pagination start index (default: 0)
  }
}

Returns a paginated list of pull requests with:

  • Array of pull requests with same details as get_pull_request

  • Total count of matching PRs

  • Pagination info (has_more, next_start)

Note on Author Filter:

  • For Bitbucket Cloud: Use the username (e.g., "johndoe")

Create Pull Request

{
  "tool": "create_pull_request",
  "arguments": {
    "workspace": "PROJ",
    "repository": "my-repo",
    "title": "Add new feature",
    "source_branch": "feature/new-feature",
    "destination_branch": "main",
    "description": "This PR adds a new feature...",  // Optional
    "reviewers": ["john.doe", "jane.smith"],  // Optional
    "close_source_branch": true  // Optional (default: false)
  }
}

Update Pull Request

{
  "tool": "update_pull_request",
  "arguments": {
    "workspace": "PROJ",
    "repository": "my-repo",
    "pull_request_id": 123,
    "title": "Updated title",  // Optional
    "description": "Updated description",  // Optional
    "destination_branch": "develop",  // Optional
    "reviewers": ["new.reviewer"]  // Optional - see note below
  }
}

Important Note on Reviewers:

  • When updating a PR without specifying the reviewers parameter, existing reviewers and their approval status are preserved

  • When providing the reviewers parameter:

    • The reviewer list is replaced with the new list

    • For reviewers that already exist on the PR, their approval status is preserved

    • New reviewers are added without approval status

  • This prevents accidentally removing reviewers when you only want to update the PR description or title

Add Comment

Add a comment to a pull request, either as a general comment or inline on specific code:

// General comment
{
  "tool": "add_comment",
  "arguments": {
    "workspace": "PROJ",
    "repository": "my-repo",
    "pull_request_id": 123,
    "comment_text": "Great work on this PR!"
  }
}

// Inline comment on specific line
{
  "tool": "add_comment",
  "arguments": {
    "workspace": "PROJ",
    "repository": "my-repo",
    "pull_request_id": 123,
    "comment_text": "Consider extracting this into a separate function",
    "file_path": "src/utils/helpers.js",
    "line_number": 42,
    "line_type": "CONTEXT"  // ADDED, REMOVED, or CONTEXT
  }
}

// Reply to existing comment
{
  "tool": "add_comment",
  "arguments": {
    "workspace": "PROJ",
    "repository": "my-repo",
    "pull_request_id": 123,
    "comment_text": "I agree with this suggestion",
    "parent_comment_id": 456
  }
}

// Add comment with code suggestion (single line)
{
  "tool": "add_comment",
  "arguments": {
    "workspace": "PROJ",
    "repository": "my-repo",
    "pull_request_id": 123,
    "comment_text": "This variable name could be more descriptive.",
    "file_path": "src/utils/helpers.js",
    "line_number": 42,
    "line_type": "CONTEXT",
    "suggestion": "const userAuthenticationToken = token;"
  }
}

// Add comment with multi-line code suggestion
{
  "tool": "add_comment",
  "arguments": {
    "workspace": "PROJ",
    "repository": "my-repo",
    "pull_request_id": 123,
    "comment_text": "This function could be simplified using array methods.",
    "file_path": "src/utils/calculations.js",
    "line_number": 50,
    "suggestion_end_line": 55,
    "line_type": "CONTEXT",
    "suggestion": "function calculateTotal(items) {\n  return items.reduce((sum, item) => sum + item.price, 0);\n}"
  }
}

The suggestion feature formats comments using GitHub-style markdown suggestion blocks that Bitbucket can render. When adding a suggestion:

  • suggestion is required and contains the replacement code

  • file_path and line_number are required when using suggestions

  • suggestion_end_line is optional and used for multi-line suggestions (defaults to line_number)

  • The comment will be formatted with a ````suggestion` markdown block that may be applicable in the Bitbucket UI

Using Code Snippets Instead of Line Numbers

The add_comment tool now supports finding line numbers automatically using code snippets. This is especially useful when AI tools analyze diffs and may struggle with exact line numbers:

// Add comment using code snippet
{
  "tool": "add_comment",
  "arguments": {
    "workspace": "PROJ",
    "repository": "my-repo",
    "pull_request_id": 123,
    "comment_text": "This variable name could be more descriptive",
    "file_path": "src/components/Button.res",
    "code_snippet": "let isDisabled = false",
    "search_context": {
      "before": ["let onClick = () => {"],
      "after": ["setLoading(true)"]
    }
  }
}

// Handle multiple matches with strategy
{
  "tool": "add_comment",
  "arguments": {
    "workspace": "PROJ",
    "repository": "my-repo",
    "pull_request_id": 123,
    "comment_text": "Consider extracting this",
    "file_path": "src/utils/helpers.js",
    "code_snippet": "return result;",
    "search_context": {
      "before": ["const result = calculate();"],
      "after": ["}"]
    },
    "match_strategy": "best"  // Auto-select highest confidence match
  }
}

Code Snippet Parameters:

  • code_snippet: The exact code line to find (alternative to line_number)

  • search_context: Optional context to disambiguate multiple matches

    • before: Array of lines that should appear before the target

    • after: Array of lines that should appear after the target

  • match_strategy: How to handle multiple matches

    • "strict" (default): Fail with error showing all matches

    • "best": Auto-select the highest confidence match

Error Response for Multiple Matches (strict mode):

{
  "error": {
    "code": "MULTIPLE_MATCHES_FOUND",
    "message": "Code snippet 'return result;' found in 3 locations",
    "occurrences": [
      {
        "line_number": 42,
        "file_path": "src/utils/helpers.js",
        "preview": "  const result = calculate();\n> return result;\n}",
        "confidence": 0.9,
        "line_type": "ADDED"
      },
      // ... more matches
    ],
    "suggestion": "To resolve, either:\n1. Add more context...\n2. Use match_strategy: 'best'...\n3. Use line_number directly"
  }
}

This feature is particularly useful for:

  • AI-powered code review tools that analyze diffs

  • Scripts that automatically add comments based on code patterns

  • Avoiding line number confusion in large diffs

Note on comment replies:

  • Use parent_comment_id to reply to any comment (general or inline)

  • In get_pull_request responses:

    • Bitbucket Server shows replies nested in a replies array

    • Bitbucket Cloud shows a parent_id field for reply comments

  • You can reply to replies, creating nested conversations

Note on inline comments:

  • file_path: The path to the file as shown in the diff

  • line_number: The line number as shown in the diff

  • line_type:

    • ADDED - For newly added lines (green in diff)

    • REMOVED - For deleted lines (red in diff)

    • CONTEXT - For unchanged context lines

Add Comment - Complete Usage Guide

The add_comment tool supports multiple scenarios. Here's when and how to use each approach:

1. General PR Comments (No file/line)

  • Use when: Making overall feedback about the PR

  • Required params: comment_text only

  • Example: "LGTM!", "Please update the documentation"

2. Reply to Existing Comments

  • Use when: Continuing a conversation thread

  • Required params: comment_text, parent_comment_id

  • Works for both general and inline comment replies

3. Inline Comments with Line Number

  • Use when: You know the exact line number from the diff

  • Required params: comment_text, file_path, line_number

  • Optional: line_type (defaults to CONTEXT)

4. Inline Comments with Code Snippet

  • Use when: You have the code but not the line number (common for AI tools)

  • Required params: comment_text, file_path, code_snippet

  • The tool will automatically find the line number

  • Add search_context if the code appears multiple times

  • Use match_strategy: "best" to auto-select when multiple matches exist

5. Code Suggestions

  • Use when: Proposing specific code changes

  • Required params: comment_text, file_path, line_number, suggestion

  • For multi-line: also add suggestion_end_line

  • Creates applicable suggestion blocks in Bitbucket UI

Decision Flow for AI/Automated Tools:

1. Do you want to suggest code changes?
   → Use suggestion with line_number
   
2. Do you have the exact line number?
   → Use line_number directly
   
3. Do you have the code snippet but not line number?
   → Use code_snippet (add search_context if needed)
   
4. Is it a general comment about the PR?
   → Use comment_text only
   
5. Are you replying to another comment?
   → Add parent_comment_id

Common Pitfalls to Avoid:

  • Don't use both line_number and code_snippet - pick one

  • Suggestions always need file_path and line_number

  • Code snippets must match exactly (including whitespace)

  • REMOVED lines reference the source file, ADDED/CONTEXT reference the destination

Note on Tasks:

  • Tasks are implemented as comments with severity: "BLOCKER" in Bitbucket Server

  • Tasks can be in OPEN or RESOLVED state

  • Only the task creator, PR author, or repository admin can edit text or delete tasks

  • Anyone with read access can mark tasks as done/undone

Development

  • npm run dev - Watch mode for development

  • npm run build - Build the TypeScript code

  • npm start - Run the built server

Troubleshooting

  1. Authentication errors: Double-check your username and app password

  2. 404 errors: Verify the workspace, repository slug, and PR ID

  3. Permission errors: Ensure your app password has the required permissions
