ZAP Protocol
Zero-Copy App Proto — High-performance Cap'n Proto RPC for AI agent communication. 10-100x faster than MCP with post-quantum security.
ZAP Protocol
ZAP (Zero-Copy App Proto) is a high-performance communication protocol for AI agents built on Cap'n Proto. It provides full MCP compatibility with 10-100x performance improvements, post-quantum security, and native support for 11 programming languages.

- Zero-Copy Performance — Cap'n Proto's zero-copy serialization eliminates parsing overhead
- MCP Compatible — Full backward compatibility with Model Context Protocol servers
- Post-Quantum Security — ML-KEM and ML-DSA cryptography for future-proof security
- Multi-Language — Native bindings for Rust, Go, Python, JavaScript, C++, and 6 more
- Agent Consensus — Built-in voting mechanism for multi-agent response aggregation
- W3C DID — Native decentralized identity support

Quick Example
interface Zap {
init @0 (client :ClientInfo) -> (server :ServerInfo);
listTools @1 () -> (tools :ToolList);
callTool @2 (call :ToolCall) -> (result :ToolResult);
listResources @3 () -> (resources :ResourceList);
readResource @4 (uri :Text) -> (content :ResourceContent);
}use zap_protocol::{Zap, ClientInfo};
#[tokio::main]
async fn main() -> Result<()> {
let client = Zap::connect("zap://localhost:9000").await?;
let info = client.init(ClientInfo::new("my-agent", "1.0.0")).await?;
let tools = client.list_tools().await?;
for tool in tools {
println!("Tool: {} - {}", tool.name, tool.description);
}
Ok(())
}ZAP vs MCP
| Feature | MCP | ZAP |
|---|---|---|
| Serialization | JSON-RPC | Cap'n Proto |
| Performance | Baseline | 10-100x faster |
| Memory | High (parsing) | Zero-copy |
| Post-Quantum | No | ML-KEM, ML-DSA |
| Threshold Signing | No | Ringtail |
| DID Support | No | W3C DIDs |
| Agent Consensus | No | Built-in voting |
ZAP includes MCP Gateway Mode for seamless migration from existing MCP servers.
