What is this?

AI agent ecosystems are marketplaces of plugins, agents, and integrations third parties extend. AgentNest publishes SDK and registry for ISV CRM and ERP plugins vetted for tenancy and security.

Why should you care?

Customers want Salesforce connector and SAP journal tools without AgentNest building every integration in-house.

See it live — copy this example

Paste into an ASP.NET Core 8+ / AgentNest project, then run with dotnet run (set your API keys in user-secrets).

// AgentNest.Sdk/IAgentNestPlugin.cs
public interface IAgentNestPlugin
{
    string Publisher { get; }
    KernelPlugin Build(IServiceProvider services);
}

// Host registration
foreach (var plugin in Directory.EnumerateFiles(pluginDir, "*.AgentNestPlugin.dll"))
    loader.RegisterFromAssembly(plugin);

What happened?

ISVs build IAgentNestPlugin; host loads signed DLLs into kernel registry after security review.
