This results in inability to e.g. unassign an issue from user. \n\nSame issue is observed when trying to set 'labels' to empty array. \n\n### Affected version\n\nLatest, connected to remote GitHub MCP server via MCP inspector.\n\n### Steps to reproduce the behavior\n\n1. Create an issue.\n2. Assign issue to user by calling issue_write with 'assignees' parameter set to [ 'anna-kogai' ] \n3. Unassign issue from user by calling issue_write with 'assignees' parameter set to []\n4. Observe tool reporting success\n\n### Expected vs actual behavior\n\nExpected behavior: The list of assignees is empty. \nActual behavior: Assignees is still set to [ 'anna-kogai' ]\n\n### Logs\n\nPaste any available logs. Redact if needed.\n","author":{"url":"https://github.com/anna-kogai","@type":"Person","name":"anna-kogai"},"datePublished":"2026-06-02T23:23:52.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/2596/github-mcp-server/issues/2596"}
