Bitbucket

You can run a Bitbucket MCP Server to empower your large language model workflows with direct access to Bitbucket workspaces, repositories, branches, pull requests, and commits. This MCP server lets you programmatically explore and manage Bitbucket resources, making it easy to build intelligent assistants that analyze code, review changes, and automate repository tasks.

How to use

Use an MCP client to query and control Bitbucket resources through the server. You can list workspaces and repositories, fetch repository details, search code across repositories, view and compare branches, manage pull requests (list, create, approve, merge, and comment), and inspect commits and file contents. Typical workflows include asking your model to summarize repository structure, locate references across code, create and merge a pull request, or fetch a file’s content from a specific branch.

To interact, connect your MCP client to one or more MCP servers configured for Bitbucket. The server exposes a set of endpoints you can invoke from your LLM tooling to perform the actions described above.

How to install

Prerequisites: ensure you have Node.js 18 or higher and a Bitbucket account with an App Password.

Step 1 — Install the MCP server and dependencies:

npm install

Step 2 — Prepare environment variables. Create a file named .env with your Bitbucket credentials and workspace:

BITBUCKET_USERNAME=your-username-or-email
BITBUCKET_APP_PASSWORD=your-app-password
BITBUCKET_WORKSPACE=default-workspace (optional)

Step 3 — Build the project:

npm run build

Step 4 — Run the MCP server locally in stdio mode using the provided command from the example configuration: either run via Node pointing to the built script or use the bundled CLI if you installed the package globally.

Configuration and start options

You can configure the MCP server in your Claude Desktop or other MCP-compatible clients by providing the following stdio configuration blocks.

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

Using the CLI to start the server

If you installed the MCP server globally, you can start it with the following command.

bitbucket-mcp
