UnverifiedIn MCP, tools are functions that the model can execute, resources are read-only data with no side effects, and prompts are reusable templates that users actively select.74% similarUnverifiedIn an Agent loop, the return values of MCP tools feed directly into the next round of LLM context, so the volume of their output has a direct impact on token consumption.74% similarUnverified建议在自定义MCP工具实现中主动向代理返回操作后的相关日志摘要，将两次工具调用合并为一次，以压缩迭代轮次并降低token消耗与延迟74% similarUnverifiedMCP implements runtime dynamic tool discovery through the tools/list method without requiring hardcoded interfaces, which is a core advantage over traditional REST API integration.73% similarUnverifiedMainstream Agent frameworks such as ReAct and Plan-and-Execute can both use MCP as a standardized implementation of the tool-calling layer.72% similar
