MCP网关工具

Traditional:  Load all tool schemas → High context usage
MCPrism:      Load metadata → Search → Fetch schemas as needed
Result:       Significantly reduced context usage

// Client loads ALL tool schemas upfront
const tools = await client.listTools();
// All schemas loaded into context immediately

// 1. Search for tools using natural language
const tools = await mcprism.searchTools("read file");
// Returns: [{ name: "read_file", description: "...", server: "filesystem" }]

// 2. Fetch full schema only when needed
const schema = await mcprism.getToolSchema("read_file");

// 3. Execute tool
const result = await mcprism.executeTool("read_file", { path: "/tmp/foo.txt" });
