mcp-bitbucket-dc

MCP (Model Context Protocol) server for Bitbucket Data Center. Enables AI assistants to search code, browse files, manage pull requests, and explore repositories through a standardized interface.

Built with FastMCP in Python. Installs via uvx — no Node.js required.

Quick Start

1. Generate a Personal Access Token

1. Log in to your Bitbucket Data Center instance
2. Go to Manage Account → HTTP access tokens
3. Click Create token
4. Set permissions: Repository Read (and Write if you need PR creation/commenting)
5. Copy the token

2. Configure Your IDE

Add to your MCP configuration (mcp.json in VS Code, claude_desktop_config.json for Claude Desktop):

{
  "mcpServers": {
    "bitbucket-dc": {
      "command": "uvx",
      "args": ["mcp-bitbucket-dc"],
      "env": {
        "BITBUCKET_HOST": "git.yourcompany.com",
        "BITBUCKET_API_TOKEN": "your-personal-access-token"
      }
    }
  }
}

That's it. The server starts automatically when your IDE connects.

3. Start Using

Ask your AI assistant:

• "Search for CompanyInfoUpdater in the codebase"
• "Show me the file structure of the api-service repo in PROJECT"
• "Get the content of src/main/Application.java from repo backend"
• "List open pull requests in PROJECT/my-repo"
• "What branches exist in PROJECT/my-repo?"

Search Query Syntax

The bitbucket_code_search tool uses Lucene-style queries:

# Simple text search
CompanyInfoUpdater

# Filter by file extension
function ext:java

# Filter by language
config lang:python

# Filter by repository or project
DatabaseHelper repo:backend-api
service project:PLATFORM

# Filter by path
controller path:src/main

# Boolean operators (must be UPPERCASE)
config AND (yaml OR yml)
test NOT unit
UserService AND ext:java AND project:CORE

Configuration

Environment Variable	Required	Description
BITBUCKET_HOST	Yes*	Bitbucket DC hostname (e.g. git.company.com)
BITBUCKET_URL	Yes*	Full base URL alternative (e.g. https://git.company.com)
BITBUCKET_API_TOKEN	Yes	Personal Access Token

* Provide either BITBUCKET_HOST or BITBUCKET_URL, not both.
