Token Optimization

v2.0.0 introduces significant token savings on every LLM request:

Configuration	Tools exposed	Est. tokens
Bitbucket Server (all groups)	29	~5,100
Bitbucket Cloud (auto-filtered)	21	~3,900
Custom group preset (e.g. pr_core,pr_review,files)	12	~2,100

Bitbucket Cloud automatically hides the 10 server-only tools with no configuration needed.

BITBUCKET_TOOL_GROUPS lets you expose only the groups relevant to your workflow — see Tool Group Filtering below.

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": "[email protected]",
        "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": "[email protected]",
        "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., "[email protected]")
• This is required for approval/review actions to work correctly

Tool Group Filtering

Reduce the number of tools sent to the LLM on every request by setting BITBUCKET_TOOL_GROUPS to a comma-separated list of group names. Only tools in the listed groups will be exposed.

Available groups

Group	Tools	Platform
pr_core	get_pull_request, list_pull_requests, create_pull_request, update_pull_request, merge_pull_request, decline_pull_request	Both
pr_comments	add_comment, delete_comment	Both
pr_review	get_pull_request_diff, set_pr_approval, set_review_status	Both
pr_tasks	list_pr_tasks, create_pr_task, update_pr_task, set_pr_task_status, delete_pr_task, convert_pr_item	Server only
commits	list_pr_commits, list_branch_commits, get_commit_detail	Both
branches	list_branches, get_branch, delete_branch	Both
files	list_directory_content, get_file_content, search_files, get_file_blame (Server only)	Both
search	search_code, search_repositories	Server only
discovery	list_projects, list_repositories	Both

Example presets

PR review workflow (~2,100 tokens):

"env": {
  "BITBUCKET_TOOL_GROUPS": "pr_core,pr_review,files"
}

Full PR management (~3,500 tokens):

"env": {
  "BITBUCKET_TOOL_GROUPS": "pr_core,pr_comments,pr_review,pr_tasks"
}

Code exploration only (~1,400 tokens):

"env": {
  "BITBUCKET_TOOL_GROUPS": "files,search,discovery"
}

When BITBUCKET_TOOL_GROUPS is not set, all applicable tools are exposed (default behaviour). Bitbucket Cloud users always have server-only tools automatically hidden regardless of this setting.

  "repository": "my-repo",
  "search_query": "TODO",
  "results": [
    {
      "file_path": "src/utils/helper.js",
      "file_name": "helper.js",
      "repository": "my-repo",
      "project": "PROJ",
      "matches": [
        {
          "line_number": 42,

          ]
        }
      ]
    }
  ],
  "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")
• For Bitbucket Server: Use the full email address (e.g., "[email protected]")

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

Line Types and Usage with add_comment:

Line Type	Description	Use with add_comment
ADDED	New line (green in diff)	Use destination_line as line_number, line_type: "ADDED"
REMOVED	Deleted line (red in diff)	Use source_line as line_number, line_type: "REMOVED"
CONTEXT	Unchanged context line	Use destination_line as line_number, line_type: "CONTEXT"

Example: Adding an inline comment on an ADDED line:

// From the diff response, we see line 29 was added with content "    newFunction()"
{
  "tool": "add_comment",
  "arguments": {
    "workspace": "PROJ",
    "repository": "my-repo",
    "pull_request_id": 123,
    "file_path": "src/components/Button.res",
    "line_number": 29,  // Use destination_line for ADDED
    "line_type": "ADDED",
    "comment_text": "Consider adding error handling here"
  }
}

    "workspace": "PROJ",
    "repository": "my-repo",
    "file_path": "src/index.ts",
    "branch": "main",  // Optional (defaults to default branch)
    "start_line": 1,  // Optional: starting line (1-based, use negative for from end)
    "line_count": 100,  // Optional: number of lines to return
    "full_content": false  // Optional: force full content (default: false)
  }
}

Smart Truncation Features:

• Automatically truncates large files (>50KB) to prevent token overload
• Default line counts based on file type:
  • Config files (.yml, .json): 200 lines
  • Documentation (.md, .txt): 300 lines
  • Code files (.ts, .js, .py): 500 lines
  • Log files: Last 100 lines
• Use start_line: -50 to get last 50 lines (tail functionality)
• Files larger than 1MB require explicit full_content: true or line parameters

Returns file content with:

• File path and branch
• File size and encoding
• Content (full or truncated based on parameters)
• Line information (if truncated):
  • Total lines in file
  • Range of returned lines
  • Truncation indicator
• Last modified information (commit, author, date)

Example responses:

// Small file - returns full content
{
  "file_path": "package.json",
  "branch": "main",
  "size": 1234,
  "encoding": "utf-8",

Get File Blame

Get per-line authorship (blame) for a file — who last modified each line, the commit hash, and author timestamp. Feed the returned commit_id into get_commit_detail to see what actually changed.

Bitbucket Server only. Bitbucket Cloud does not expose a blame API.

// Full-file blame
{
  "tool": "get_file_blame",
  "arguments": {
    "workspace": "PROJ",
    "repository": "my-repo",
    "file_path": "src/index.ts"
  }

// Blame for a specific branch and line range
{
  "tool": "get_file_blame",
  "arguments": {
    "workspace": "PROJ",
    "repository": "my-repo",
    "file_path": "src/index.ts",
    "branch": "main",
    "start_line": 100,
    "line_count": 20
  }
}

// Ungrouped — one entry per line
{
  "tool": "get_file_blame",
  "arguments": {
    "workspace": "PROJ",
    "repository": "my-repo",
    "file_path": "src/index.ts",
    "group_by_commit": false
  }
}

Parameters:

• file_path: File path, e.g. "src/index.ts" (required)
• branch: Branch name (optional, defaults to default branch)
• start_line: Starting line (1-based) to limit output (optional)
• line_count: Number of lines to return from start_line (optional)
• group_by_commit: Group contiguous lines from the same commit into ranges (default: true)

Response (grouped, default):

{
  "file_path": "src/index.ts",
  "branch": "main",
  "total_lines": 1982,
  "returned_lines": { "start": 1, "end": 1982 },
  "unique_commits": 42,
  "unique_authors": 16,
  "grouped": true,
  "blame": [
    {
      "line_start": 1,
      "line_end": 4,
      "commit_id": "fbbe61e95f51abb8aed8dd5a472074a77b3d0f46",
      "commit_display_id": "fbbe61e95f5",
      "author": { "name": "Jane Doe", "email": "[email protected]" },
      "date": "2025-04-15T12:01:01.000Z",
      "original_file_name": "src/index.ts"
    }
  ]
}

Response (ungrouped, group_by_commit: false): each blame entry has a single line field instead of line_start/line_end.

Useful for:

• Finding the main authors of a file before requesting reviews
• Tracing who introduced a particular line or block
• Feeding commit_id into get_commit_detail to see the full diff of a blamed change
• Identifying code ownership when refactoring shared modules

• For Bitbucket Cloud, this returns workspaces (not projects in the traditional sense)
• For Bitbucket Server, this returns both personal and team projects

This tool is particularly useful for:

• Discovering available projects/workspaces for your account
• Finding project keys needed for other API calls
• Identifying projects you have specific permissions on
• Browsing organizational structure

List Repositories

List repositories within a specific project/workspace or across all accessible repositories:

// List all repositories in a workspace/project
{
  "tool": "list_repositories",
  "arguments": {
    "workspace": "PROJ",  // Required for Bitbucket Cloud, optional for Server
    "limit": 25,          // Optional (default: 25)
    "start": 0            // Optional: for pagination (default: 0)
  }
}

{
  "tool": "list_repositories",
  "arguments": {
    "limit": 100
  }
}

// Filter by repository name
{
  "tool": "list_repositories",
  "arguments": {
    "workspace": "PROJ",
    "name": "frontend",  // Partial name match
    "limit": 50
  }
}

// Filter by permission level (Bitbucket Server only)
{
  "tool": "list_repositories",
  "arguments": {
    "workspace": "PROJ",
    "permission": "REPO_WRITE",  // REPO_READ, REPO_WRITE, REPO_ADMIN
    "limit": 100
  }
}

Parameters:

• workspace: Project key (Server) or workspace slug (Cloud)
  • Required for Bitbucket Cloud
  • Optional for Bitbucket Server (omit to list all accessible repos)
• name: Filter by repository name (partial match, optional)
• permission: Filter by permission level (Bitbucket Server only, optional)
  • REPO_READ: Read access
  • REPO_WRITE: Write access
  • REPO_ADMIN: Admin access

Returns repository information:

{
  "repositories": [
    {
      "slug": "my-repo",
      "id": 5678,
      "name": "My Repository",
      "description": "Repository description",
      "project_key": "PROJ",
      "project_name": "My Project",
      "state": "AVAILABLE",  // AVAILABLE, INITIALISING, INITIALISATION_FAILED (Server)
      "is_public": false,
      "is_forkable": true,
      "clone_urls": {
        "http": "https://bitbucket.yourcompany.com/scm/PROJ/my-repo.git",
        "ssh": "ssh://[email protected]:7999/PROJ/my-repo.git"
      },
      "url": "https://bitbucket.yourcompany.com/projects/PROJ/repos/my-repo"
    }
    // ... more repositories
  ],
  "total_count": 42,
  "start": 0,
  "limit": 25,
  "has_more": true,
  "next_start": 25,
  "workspace": "PROJ"
}

Important Notes:

• Bitbucket Cloud requires the workspace parameter. If omitted, you'll receive an error message
• Bitbucket Server allows listing all accessible repos by omitting the workspace parameter
• Clone URLs are provided for both HTTP(S) and SSH protocols

This tool is particularly useful for:

• Discovering available repositories in a project/workspace
• Finding repository slugs needed for other API calls
• Identifying repositories you have specific permissions on
• Getting clone URLs for repositories
• Browsing repository structure within an organization

Search Repositories

Search for repositories by name or description (Bitbucket Server only):

// Basic search
{
  "tool": "search_repositories",
  "arguments": {
    "search_query": "backend",

  }
}

// Search within a specific project
{
  "tool": "search_repositories",
  "arguments": {
    "search_query": "dashboard",
    "workspace": "PROJ",
    "limit": 25
  }
}

  }
}

Note: Comments with replies cannot be deleted. Only the comment author, PR author, or repository admin can delete comments.

    "repository": "my-repo",
    "pull_request_id": 123,
    "comment_id": 456
  }

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
