Get a suggested commit message for merging a pull request.
AI agents call get_commit_message_suggestion to retrieve information from Bitbucket Server MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information (a suggested message) to assist with merge operations but does not itself execute the merge, commit changes, or modify any repository state. It has no side effects and poses minimal risk even if misused by an AI agent, as the worst outcome would be suggesting an inappropriate commit message text, which humans would review before applying it.
From the tool's definition Tool is described as getting/retrieving a 'suggested commit message' — it queries and returns data without modifying any state in Bitbucket.
