Key features of Solo.io

• agentgateway: a gateway for service, LLM and MCP traffic with MCP and A2A support, model aliasing and token weighted rate limiting.
• agentregistry: a registry for MCP servers, agents, skills and prompts.
• agentdesktop: visibility and control for agents on the desktop.
• Istio and kgateway: service mesh and gateway for cloud connectivity.
• Platform controls: MCP server provenance checks, approved catalog workflows and centralized policy.
