When using SSE (Server-Sent Events) MCP Server High Latency observed during execution of agentic workflows Issue High latency observed when fetching responses from an external source during execution of agentic workflows in ServiceNow via the AI agents module. The issue affects both custom agents and out-of-the-box (OOB) workflows. ReleaseAllCause1. The KnowledgeBase MCP Server was generating excessive metadata due to SSE streaming, which ServiceNow does not support, leading to prolonged processing times. 2. Large input/output token counts (25k+ input tokens and ~700 output tokens) and redundant ReAct processing (input planning and response synthesis) exacerbated latency.Resolution1. Remove SSE (Server-Sent Events) functionality from the KnowledgeBase MCP Server to reduce metadata sent over, as ServiceNow does not support SSE for this use case. 2. Optimize the MCP tool to return a smaller output, as excessive metadata and large input/output token counts contribute to latency. 3. Ensure the MCP server configuration aligns with ServiceNow's ReAct flow to avoid redundant processing.
