Developers building AI agents often struggle when their workflows must pause mid-execution to ask users for clarification, request large language model (LLM)-generated content, or provide real-time progress updates during long-running operations, stateless MCP servers can’t handle these scenarios. This solves these limitations by introducing three client capabilities from the MCP specification:
