CompleteRequestSchema MCP Protocol Support
Resolved 💬 3 comments Opened May 7, 2025 by mettamatt Closed Jan 3, 2026
Feature Request
Implement client-side support for the CompleteRequestSchema MCP protocol.
Current Behavior
Currently, Claude Code and Claude Desktop do not utilize the CompleteRequestSchema MCP protocol. When a server implements these features, the client does not send CompleteRequest messages to get completion suggestions for prompt arguments.
Why This Is Valuable
This functionality would significantly improve the user experience by reducing repetitive data entry for frequently used values in prompt arguments.
The client-side implementation would need to send CompleteRequest messages when a user is filling in a prompt argument field.
