| Aspect | Grand Plaza (vendor website) | A2A Registry (public registry site) | MCP Gateway & Registry (project site) |
|---|---|---|---|
| Starting Price | Not publicly listed | Listing is stated as free for public entries | Open-source (community code hosting); operational costs depend on deployment |
| Best For | Enterprises seeking an A2A-focused discoverability and collaboration layer | Public discovery directory / open registry routing model | Organizations seeking a governed internal control plane for MCP servers/agents/skills |
| Key Strength | Vendor materials emphasize discoverability as a core problem in the A2A era | Clear public positioning around being a global A2A registry and routing endpoint | Explicitly positions as a governed control plane across AI assets |
| Key Weakness | Limited public evidence: no pricing, limited documentation, and no independent reviews located | Public registry model may not meet regulated/private enterprise requirements | May require increased self-management; depends on community maturity |
