Remote Tool Invocation With Parameter Marshaling

via “tool invocation with schema-based argument marshalling”

TypeScript runtime and CLI for connecting to configured Model Context Protocol servers.

Unique: Implements MCP-compliant tool invocation with client-side schema validation and automatic argument serialization, supporting the full MCP tool definition spec including complex types, optional parameters, and nested objects

vs others: More reliable than manual function calling because schema validation catches argument errors before sending to the server, reducing round-trips and improving agent reliability
