Get all available issue link types (Blocks, Duplicate, Relates, etc.). Use before add_issue_link to find correct link type names.
AI agents call quinta-jira_get_link_types to retrieve information from JIRA MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a pure read operation that queries and returns metadata about available link types in Jira. It does not create, modify, delete, or execute any operations—it merely retrieves existing configuration data. The severity is low as misuse poses minimal risk; returning wrong link type names would only cause errors when passed to add_issue_link, not independent harm.
From the tool's definition Tool retrieves 'all available issue link types' with examples like 'Blocks, Duplicate, Relates'. The description explicitly states 'Use before add_issue_link', indicating this is a lookup/query operation with no side effects.
