Struct McpCallResult 

pub struct McpCallResult {
    pub content: Vec<McpContentItem>,
    pub is_error: bool,
}

Result of calling an MCP tool.

Contains the content returned by the tool execution and a flag indicating whether an error occurred.

Fields

• content - List of content items (text, images, or resources)
• is_error - Whether the tool execution failed

Error Handling

When is_error is true, the content typically contains error messages or diagnostic information. Clients should check this flag before processing the content.

Example

let result = McpCallResult {
    content: vec![McpContentItem::Text {
        text: "File contents here".to_string(),
    }],
    is_error: false,
};

if !result.is_error {
    for item in result.content {
        // Process content
    }
}

Fields

content: Vec<McpContentItem>

Content items returned by the tool

is_error: bool

Whether the tool execution encountered an error
