Struct ToolSummary 

pub struct ToolSummary {
    pub tool_id: String,
    pub description: String,
}

A lightweight, schema-free description of a single MCP tool.

Returned by ToolIndex::search so that an external client can discover what tools exist without receiving every tool’s full JSON input schema. Once the client has identified the specific tool it needs, it calls get_tool_schema with the tool_id to retrieve the full schema lazily.

Naming convention

tool_id uses the double-underscore qualified format "<server_name>__<tool_name>" so that the ID is both human-readable and usable as the tool_id argument to get_tool_schema and invoke_tool without any further look-up.

Fields

tool_id: String

Qualified tool identifier: "<server_name>__<tool_name>".

Pass this string directly to get_tool_schema or invoke_tool.

description: String

One-line human-readable description, or an empty string if the upstream MCP server did not provide one.
