Auto-generates a PR title from branch naming convention (<type>/<taskId>_<description>), resolves the default target branch, validates that the branch has been pushed, and optionally adds reviewers and draft status.
reply_to_pr_comment	Posts a reply to a specific pull request comment by its ID. Use the comment IDs returned by get_pr_comments. Useful for acknowledging a review comment or explaining what fix was applied. Pass repoPath (from git rev-parse --show-toplevel) to auto-detect project, repo, and branch.

Available Prompts

Name	Description
review-pr-comments	Fetches and displays all unresolved PR review comments as formatted, navigable links
create-pull-request	Analyzes the current branch, drafts a PR title and short description following branch naming conventions, confirms with the user, then creates the pull request on Bitbucket Data Center.
rebase-onto-main	Detects the default branch (main or master), fetches the latest changes, rebases the current branch onto it, resolves any conflicts, and force-pushes.

For Developers

Scripts

Command	Description
pnpm dev	Run the MCP server
pnpm test	Run tests
pnpm typecheck	Type-check the project
pnpm inspect	Launch MCP Inspector UI

Debugging with MCP Inspector

The project includes @modelcontextprotocol/inspector as a dev dependency. Use it to interactively test tools, resources, and prompts exposed by the server.

Start the inspector:

pnpm inspect

The UI opens at http://localhost:6274.

Connect to the server in the UI:

Field	Value
Transport	STDIO
Command	tsx
Arguments	src/index.ts

Click Connect. The inspector spawns the server process and proxies the MCP protocol.

Alternatively, pass the command directly on the CLI:

npx @modelcontextprotocol/inspector tsx src/index.ts

Environment variables: Set BITBUCKET_URL and BITBUCKET_TOKEN in the Environment Variables section of the inspector UI before clicking Connect.
