Bitbucket Automation via Rube MCP

Automate Bitbucket operations including repository management, pull request workflows, branch operations, issue tracking, and workspace administration through Composio's Bitbucket toolkit.

Prerequisites

• Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
• Active Bitbucket connection via RUBE_MANAGE_CONNECTIONS with toolkit bitbucket
• Always call RUBE_SEARCH_TOOLS first to get current tool schemas

Setup

Get Rube MCP: Add https://rube.app/mcp as an MCP server in your client configuration. No API keys needed — just add the endpoint and it works.

1. Verify Rube MCP is available by confirming RUBE_SEARCH_TOOLS responds
2. Call RUBE_MANAGE_CONNECTIONS with toolkit bitbucket
3. If connection is not ACTIVE, follow the returned auth link to complete Bitbucket OAuth
4. Confirm connection status shows ACTIVE before running any workflows

Core Workflows

1. Manage Pull Requests

When to use: User wants to create, review, or inspect pull requests

Tool sequence:

1. BITBUCKET_LIST_WORKSPACES - Discover accessible workspaces [Prerequisite]
2. BITBUCKET_LIST_REPOSITORIES_IN_WORKSPACE - Find the target repository [Prerequisite]
3. BITBUCKET_LIST_BRANCHES - Verify source and destination branches exist [Prerequisite]
4. BITBUCKET_CREATE_PULL_REQUEST - Create a new PR with title, source branch, and optional reviewers [Required]
5. BITBUCKET_LIST_PULL_REQUESTS - List PRs filtered by state (OPEN, MERGED, DECLINED) [Optional]
6. BITBUCKET_GET_PULL_REQUEST - Get full details of a specific PR by ID [Optional]
7. BITBUCKET_GET_PULL_REQUEST_DIFF - Fetch unified diff for code review [Optional]
8. BITBUCKET_GET_PULL_REQUEST_DIFFSTAT - Get changed files with lines added/removed [Optional]

Key parameters:

• workspace: Workspace slug or UUID (required for all operations)
• repo_slug: URL-friendly repository name
• source_branch: Branch with changes to merge
• destination_branch: Target branch (defaults to repo main branch if omitted)
• reviewers: List of objects with uuid field for reviewer assignment
• state: Filter for LIST_PULL_REQUESTS - OPEN, MERGED, or DECLINED
• max_chars: Truncation limit for GET_PULL_REQUEST_DIFF to handle large diffs

Pitfalls:

• reviewers expects an array of objects with uuid key, NOT usernames: [{"uuid": "{...}"}]
• UUID format must include curly braces: {123e4567-e89b-12d3-a456-426614174000}
• destination_branch defaults to the repo's main branch if omitted, which may not be main
• pull_request_id is an integer for GET/DIFF operations but comes back as part of PR listing
• Large diffs can overwhelm context; always set max_chars (e.g., 50000) on GET_PULL_REQUEST_DIFF

2. Manage Repositories and Workspaces

When to use: User wants to list, create, or delete repositories or explore workspaces

Tool sequence:

1. BITBUCKET_LIST_WORKSPACES - List all accessible workspaces [Required]
2. BITBUCKET_LIST_REPOSITORIES_IN_WORKSPACE - List repos with optional BBQL filtering [Required]
3. BITBUCKET_CREATE_REPOSITORY - Create a new repo with language, privacy, and project settings [Optional]
4. BITBUCKET_DELETE_REPOSITORY - Permanently delete a repository (irreversible) [Optional]
5. BITBUCKET_LIST_WORKSPACE_MEMBERS - List members for reviewer assignment or access checks [Optional]

Key parameters:

• workspace: Workspace slug (find via LIST_WORKSPACES)
• repo_slug: URL-friendly name for create/delete
• q: BBQL query filter (e.g., name~"api", project.key="PROJ", is_private=true)
• role: Filter repos by user role: member, contributor, admin, owner
• sort: Sort field with optional - prefix for descending (e.g., -updated_on)
• is_private: Boolean for repository visibility (defaults to true)
• project_key: Bitbucket project key; omit to use workspace's oldest project

Pitfalls:

• BITBUCKET_DELETE_REPOSITORY is irreversible and does not affect forks
• BBQL string values MUST be enclosed in double quotes: name~"my-repo" not name~my-repo
• repository is NOT a valid BBQL field; use name instead
• Default pagination is 10 results; set pagelen explicitly for complete listings
• CREATE_REPOSITORY defaults to private; set is_private: false for public repos

3. Manage Issues

When to use: User wants to create, update, list, or comment on repository issues

Tool sequence:

1. BITBUCKET_LIST_ISSUES - List issues with optional filters for state, priority, kind, assignee [Required]
2. BITBUCKET_CREATE_ISSUE - Create a new issue with title, content, priority, and kind [Required]
3. BITBUCKET_UPDATE_ISSUE - Modify issue attributes (state, priority, assignee, etc.) [Optional]
4. BITBUCKET_CREATE_ISSUE_COMMENT - Add a markdown comment to an existing issue [Optional]
5. BITBUCKET_DELETE_ISSUE - Permanently delete an issue [Optional]

Key parameters:

• issue_id: String identifier for the issue
• title, content: Required for creation
• kind: bug, enhancement, proposal, or task
• priority: trivial, minor, major, critical, or blocker
• state: new, open, resolved, on hold, invalid, duplicate, wontfix, closed
• assignee: Bitbucket username for CREATE; assignee_account_id (UUID) for UPDATE
• due_on: ISO 8601 format date string

Pitfalls:

• Issue tracker must be enabled on the repository (has_issues: true) or API calls will fail
• CREATE_ISSUE uses assignee (username string), but UPDATE_ISSUE uses assignee_account_id (UUID) -- they are different fields
• DELETE_ISSUE is permanent with no undo
• state values include spaces: "on hold" not "on_hold"
• Filtering by assignee in LIST_ISSUES uses account ID, not username; use "null" string for unassigned

4. Manage Branches

When to use: User wants to create branches or explore branch structure

Tool sequence:

1. BITBUCKET_LIST_BRANCHES - List branches with optional BBQL filter and sorting [Required]
2. BITBUCKET_CREATE_BRANCH - Create a new branch from a specific commit hash [Required]

Key parameters:

• name: Branch name without refs/heads/ prefix (e.g., feature/new-login)
• target_hash: Full SHA1 commit hash to branch from (must exist in repo)
• q: BBQL filter (e.g., name~"feature/", name="main")
• sort: Sort by name or -target.date (descending commit date)
• pagelen: 1-100 results per page (default is 10)

Pitfalls:

• CREATE_BRANCH requires a full commit hash, NOT a branch name as target_hash
• Do NOT include refs/heads/ prefix in branch names
• Branch names must follow Bitbucket naming conventions (alphanumeric, /, ., _, -)
• BBQL string values need double quotes: name~"feature/" not name~feature/

5. Review Pull Requests with Comments

When to use: User wants to add review comments to pull requests, including inline code comments

Tool sequence:

1. BITBUCKET_GET_PULL_REQUEST - Get PR details and verify it exists [Prerequisite]
2. BITBUCKET_GET_PULL_REQUEST_DIFF - Review the actual code changes [Prerequisite]
3. BITBUCKET_GET_PULL_REQUEST_DIFFSTAT - Get list of changed files [Optional]
4. BITBUCKET_CREATE_PULL_REQUEST_COMMENT - Post review comments [Required]

Key parameters:

• pull_request_id: String ID of the PR
• content_raw: Markdown-formatted comment text
• content_markup: Defaults to markdown; also supports plaintext
• inline: Object with path, from, to for inline code comments
• parent_comment_id: Integer ID for threaded replies to existing comments
