Double hop performance tax in MCP request routing

7/10 High

Every MCP tool call requires two round trips (agent → MCP server → tool → MCP server → agent) instead of direct calls, adding latency and overhead to each interaction. This architectural inefficiency compounds at scale and makes production deployments slower.

Query: “What are the most common pain points with MCP for developers in 2025?”4/7/2026

Every time an AI agent wants to call a tool in MCP, the request doesn't go directly to the tool. It makes two trips. The agent sends a JSON-RPC request to the MCP Server, the server parses it, reformats it, and forwards it to the actual tool.
