Struct McpToolAdapter 

pub struct McpToolAdapter {
    pub openai_name: String,
    pub mcp_tool_name: String,
    pub description: String,
    pub input_schema: Value,
    pub result_cap_bytes: usize,
    pub client: Arc<McpClient>,
}

A Rig dynamic-tool view of one MCP-discovered tool.

openai_name is what the LLM sees and what ToolDyn::name returns. mcp_tool_name is the original name from tools/list, used on the wire when dispatching back into the MCP server. client is shared (via Arc) so multiple adapters fronting the same MCP server reuse one connection.

Fields

openai_name: String

mcp_tool_name: String

description: String

input_schema: Value

result_cap_bytes: usize

client: Arc<McpClient>

Implementations

impl McpToolAdapter

pub async fn from_client_tools( client: Arc<McpClient>, result_cap_bytes: usize, ) -> Result<Vec<McpToolAdapter>>

Build one adapter per tool the server advertises. The server’s local name (from McpClient::name) becomes the prefix.
