-The Model Context Protocol (MCP) provides a standardized way for servers to provide argument completion suggestions for prompts and resource URIs. This enables rich, IDE-like experiences where users receive contextual suggestions while entering argument values.
+The Model Context Protocol (MCP) provides a standardized way for servers to offer argument autocompletion suggestions for prompts and resource URIs. This enables rich, IDE-like experiences where users receive contextual suggestions while entering argument values.
 
 ## User Interaction Model
 
-Completion in MCP is designed to support interactive user experiences similar to IDE code completion. A recommended implementation pattern is showing completion suggestions in a dropdown or popup menu as users type, with the ability to filter and select from available options.

 ## Implementation Considerations
 
-1. Servers SHOULD:
+1. Servers **SHOULD**:
    - Return suggestions sorted by relevance
    - Implement fuzzy matching where appropriate
    - Rate limit completion requests
    - Validate all inputs
