UnverifiedThe quality of MCP tool descriptions is critically important; vague descriptions cause the LLM to call the wrong tool or use incorrect parameters, and each retry cycle can consume 400 to 1,000 tokens depending on context size.76% similarUnverifiedWhen using a large model as the sole central scheduler to coordinate multiple MCP tools, if the number of tool calls is too large, the model is prone to scheduling confusion, resulting in poor stability and weak scalability.76% similarUnverifiedThe longer the tool chain integrating multiple generation stages, the higher the risk of error accumulation.73% similarUnverifiedEvery tool call in MCP must go through serialization, inter-process communication, and deserialization, which causes perceptible latency in scenarios with few tools but high call frequency.73% similar
