Feature request: Context-Aware Completion Enhancement (MCP 2025-06-18) #395
Description
Summary
Implement context-aware completion from PR #598 to enable intelligent completion suggestions based on previously resolved arguments.
Current completion requests lack context about previously resolved variables, limiting completion intelligence for multi-argument templates.
Solution
Add optional CompletionContext to completion requests:
#[derive(Debug, Serialize, Deserialize, Clone, Default)]
pub struct CompletionContext {
#[serde(skip_serializing_if = "Option::is_none")]
pub arguments: Option<HashMap<String, String>>,
}
#[derive(Debug, Serialize, Deserialize, Clone)]
pub struct CompleteRequestParam {
pub r#ref: Reference,
pub argument: ArgumentInfo,
#[serde(skip_serializing_if = "Option::is_none")]
pub context: Option<CompletionContext>, // NEW
}
