search_fields
AI agents call search_fields to retrieve information from MCP Atlassian + Bitbucket without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name suggests retrieval or querying of field metadata/definitions within Jira/Confluence/Bitbucket, with no indication of modification, deletion, or execution. The empty description reduces confidence, but the context of sibling Read-category tools and the semantic meaning of 'search' support Read classification. No side effects or data mutation are implied.
From the tool's definition Tool name 'search_fields' indicates a query/search operation typical of Read category. Description is empty, limiting certainty.
