Is it possible to use StructuredTool with any Agent?

I am was trying to figure out a way to use StructuredTool as a multi-input Tool and used from an Agent; for example, an ZeroShotAgent. Sadly, looks like all the agents are defined to use Tool[] instead of StructuredTool[ ] or ObjectTool[ ]. Is there any way I can do that?

This is my code, the final Tool (QuerySpecificFieldSupabaseTool) is an StructuredTool which is incompatible with the Agents.

export class SupabaseToolkit extends Toolkit {
    tools: Tool[];
    cli: SupabaseClient
    dialect = "supabase"

    constructor(cli: SupabaseClient) {
        super()
        this.cli = cli
        this.tools = [
            new QuerySupabaseTool(cli),
            new ListTablesSupabaseTool(cli),
            new ListFieldsSupabaseTool(cli),
            new QuerySpecificFieldSupabaseTool(cli),
        ]
    }
}

Solution

As of 02 May 2023 (likely subject to change):
Structured Tools can only accept one string argument in order to be compatible with most existing Agents. The one Agent than can accept a structured tool with multiple arguments is the STRUCTURED_CHAT_ZERO_SHOT_REACT_DESCRIPTION Agent type, see docs here.

This is discussed in the blog post that introduces Structured Tools.

Q: Can I use structured tools with existing agents?

A: If your structured tool accepts one string argument: YES, it will still work with existing agents. However, structured tool with more than one argument are not directly compatible with the following agents without further customization:
