UnverifiedThe scalability problem with MCP is that the name, description, and schema of each tool must be placed in the system prompt, and 20 servers with 15 tools each would occupy most of the context window.75% similarUnverifiedA healthy MCP Server typically contains 5–20 purpose-specific tools rather than integrating a large number of tools.74% similarUnverifiedMCP's default implementation injects the schemas of all registered tools into the context at session initialization; when the number of tools reaches dozens or even hundreds, tool descriptions alone may consume thousands of tokens.73% similarUnverifiedMCP的工具发现机制通过tools/list接口查询已连接Server的工具列表，参数schema基于JSON Schema规范72% similarUnverified大约20行Python代码即可构建一个可工作的MCP服务器72% similar
