resolve_pr_comment · Bitbucket MCP: Risk & Policy

WHAT IT DOES

What resolve_pr_comment does on Bitbucket

AI agents use resolve_pr_comment to create or update resources in Bitbucket — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Bitbucket environment.

WHY IT NEEDS A POLICY

Why resolve_pr_comment needs a policy

This tool creates or modifies data reversibly by changing the resolution status of a PR comment. It does not execute code, delete data, or perform financial operations. The action is reversible (comments can be marked as resolved or unresolved again), placing it in the Write category. Severity is low because the blast radius of misuse is limited to PR comment metadata with no impact on code, builds, or deployments.

From the tool's definition Tool description states: 'Mark a PR comment as resolved or unresolved.' This modifies the state of a PR comment (resolved/unresolved status) reversibly.
