Bitbucket Mcp

Bitbucket MCP Server

This project provides an implementation of the Model Context Protocol (MCP) server in Python. It allows users to interact with Bitbucket repositories through a standardized interface, supporting code searches, repository management, and more.

Features

• Implements the MCP server protocol for Bitbucket integration
• Searches code in Bitbucket repositories with support for multiple pages of results
• Retrieves repository information and commit history
• Fetches file contents from repositories
• Creates branches and pull requests
• Automatically masks sensitive credentials in search results
• Returns data in JSON format
• Includes syntax rules for searching files in Bitbucket

Project Structure

bitbucket_mcp/
├── __init__.py          # Package init
├── __main__.py          # CLI entry point (argparse, logging, mcp.run)
├── server.py            # FastMCP instance + plugin-style tool/prompt registration
├── client.py            # BitbucketClient class (unified pagination, shared instance)
├── credentials.py       # mask_credentials() utility
├── config.py            # BitbucketConfig dataclass + env-var validation
└── prompts.py           # SYNTAX_RULES + TOOL_PROMPTS dictionary

Adding a New Tool

1. Add a method to BitbucketClient in client.py.
2. Add a tool function in server.py using the @bitbucket_tool decorator — the function signature defines the MCP input schema, and the body delegates to the client via _call().
3. (Optional) Add a prompt by adding an entry to TOOL_PROMPTS in prompts.py — it's auto-registered, no @mcp.prompt() boilerplate needed.

Adding a New Prompt

Just add an entry to the TOOL_PROMPTS dict in prompts.py. The prompt is automatically registered as {key}_prompt at server startup.

Requirements

• Python 3.11+
• atlassian-python-api library
• mcp library with CLI support
• uv for project management

Environment Variables

The server requires the following environment variables:

• BITBUCKET_WORKSPACE - Your Bitbucket workspace name
• APP_USERNAME - Bitbucket username
• APP_PASSWORD - Bitbucket password or app password
• BITBUCKET_URL - (Optional) Bitbucket API URL, defaults to https://api.bitbucket.org/

Configuration Example

"BitbucketMCP": {
      "type": "local",
      "command": ["uv", "run", "bitbucket-mcp"],
      "environment": {
        "BITBUCKET_WORKSPACE": "test_workspace",
        "APP_USERNAME": "username",
        "APP_PASSWORD": "password"
      }
}

Alternatively, you can still use the backward-compatible shim:

"BitbucketMCP": {
      "type": "local",
      "command": ["uv", "run", "server.py"],
      "environment": {
        "BITBUCKET_WORKSPACE": "test_workspace",
        "APP_USERNAME": "username",
        "APP_PASSWORD": "password"
      }
}
