BitBucket-MCP-To-Review-PRs

A read-only MCP (Model Context Protocol) server for the Bitbucket Cloud REST API v2.0. Enables AI assistants (Kiro, VS Code, Claude Desktop, etc.) to browse workspaces, repositories, and review pull requests — all without modifying anything in Bitbucket.

Features

• List workspaces and repositories

• List, view, and review pull requests

• Get PR diffs, diffstats, comments, and commits

• Parse Bitbucket PR URLs for one-shot review context

• View file contents at any commit

• Automatic pagination and rate limit handling

• Strictly read-only (GET requests only)
