Struct CompositeToolConfig 

pub struct CompositeToolConfig {
    pub name: String,
    pub description: String,
    pub tools: Vec<String>,
    pub strategy: CompositeStrategy,
}

Configuration for a composite tool that fans out to multiple backend tools.

Composite tools appear in ListTools responses alongside regular tools. When called, the proxy dispatches the request to every tool in tools concurrently (for parallel strategy) and aggregates all results.

Example

[[composite_tools]]
name = "search_all"
description = "Search across all knowledge sources"
tools = ["github/search", "jira/search", "docs/search"]
strategy = "parallel"

Fields

name: String

Name of the composite tool as it appears to MCP clients.

description: String

Human-readable description of the composite tool.

tools: Vec<String>

Fully-qualified backend tool names to fan out to (e.g. "github/search").

strategy: CompositeStrategy

Execution strategy (default: parallel).
