The server provides the following tools through the MCP interface:

linear_create_issue

Creates a new Linear issue with the following parameters:

• title (required): Issue title
• teamId (required): Team ID to create issue in
• description (optional): Issue description (markdown supported)
• priority (optional): Priority level (0-4)
• status (optional): Initial status name

linear_search_issues

Search Linear issues with flexible filtering:

• query (optional): Text to search in title/description
• teamId (optional): Filter by team
• status (optional): Filter by status
• assigneeId (optional): Filter by assignee
• priority (optional): Priority level (0-4)
• limit (optional, default: 10): Max results to return

linear_sprint_issues

• teamId (required): Team ID to get sprint issues for

linear_search_teams

Search and retrieve Linear teams:

• query (optional): Text to search in team names

linear_filter_sprint_issues

Filter current sprint issues by status and automatically filters to the current user:

• teamId (required): Team ID to get sprint issues for
• status (required): Status to filter by (e.g. "Pending Prod Release")

linear_bulk_update_status

Update the status of multiple Linear issues at once:

• issueIds (required): List of issue IDs to update (e.g. ["ENG-123", "DATA-456"])
• targetStatus (required): Target status to set for all issues (e.g. "In Progress")
