The Cognitive Backbone for Autonomous Agents
Open source protocol for secure AI agent communication. One gateway, unlimited agents, unlimited locations — enterprise-scale deployment with zero licensing costs.
Why Choose AXCP?
Ultra-Low Latency
Eliminate the performance penalty of traditional cloud architectures with QUIC transport and 0-RTT handshakes that reduce latency by up to 80% compared to TCP-based protocols.
Open Source Core
One gateway, unlimited agents, unlimited locations — zero licensing costs. AXCP Core is Apache 2.0. Deploy across 5 offices or 50 countries with enterprise-scale security. Advanced and Enterprise tiers add mTLS, Differential Privacy, and compliance features for specialized needs.
Universal Interoperability
Connect any agent, in any language, over any stack. AXCP abstracts away transport details so Rust micro-services, Python ML pipelines, Go edge agents — even legacy MCP, A2A, and ACP systems — can exchange context through a single, strongly-typed envelope. Build heterogeneous swarms without rewriting code.
Security by Default
Security built into every message. TLS 1.3 transport, Ed25519 signatures, DID-based identity, and replay protection — all in Core. Need Differential Privacy? Upgrade to Advanced/Enterprise.
Features
QUIC/Datagram
CoreModern transport protocol with built-in TLS 1.3 encryption, 0-RTT handshake, and improved performance over traditional TCP, reducing latency by up to 80%.
Delta-Sync CRDT
CRDT = Conflict-free Replicated Data Type
Advanced
Conflict-free Replicated Data Types for seamless state synchronization across distributed systems, ensuring eventual consistency without conflicts.
Differential Privacy
EnterpriseMathematically-proven privacy guarantees for sensitive data processing, ensuring individual data points cannot be reverse-engineered from aggregates.
Adaptive Profiles
CoreDynamically negotiate security profiles between agents based on capabilities and requirements. Profile negotiation is built into the handshake protocol.
Enclave Ready
AdvancedHardware-backed security with support for Trusted Execution Environments (TEEs) like Intel SGX and AMD SEV, providing confidential computing capabilities.
Observability
EnterprisePrometheus metrics, OpenTelemetry integration, and distributed tracing built-in, providing deep insights into system performance and behavior in production environments.

Understanding AXCP
AI agents are becoming part of our daily lives. They need a secure way to talk to each other. Here's why AXCP Core is the answer.
The Problem Today
AI agents from different companies can't securely communicate with each other. It's like having phones that only work within the same carrier — but worse, because there's no standard for security.
- ✗ No standard for agent-to-agent authentication
- ✗ Messages can be intercepted or faked
- ✗ No way to verify "who said what"
AXCP Core Solves This
AXCP gives every AI agent a verified identity and signs every message cryptographically. Think of it as "HTTPS for AI agents" — but even more secure.
- ✓ Every agent has a unique, verifiable identity (DID)
- ✓ Every message is signed — impossible to fake
- ✓ Replay attacks are blocked automatically
What AXCP Core Enables
Multi-Vendor Collaboration
Claude, GPT, Gemini, and any other AI can work together securely on the same task.
Trust Without Trusting
Cryptographic signatures prove authenticity. You don't need to trust — you can verify.
Built for Speed
QUIC transport means sub-millisecond latency. Security doesn't slow you down.
Open Standard
Apache 2.0 licensed. Use it, modify it, build on it. No vendor lock-in, ever.
Enterprise-Scale Deployment — With Free, Open Source
AXCP Core isn't a "demo tier." It's a production-ready protocol that can power your entire organization.

✓ All 12 agents communicate securely
✓ Ed25519 signatures on every message
✓ Zero licensing costs
Global Reach
Connect agents from any location worldwide. If they can reach your gateway, they can communicate securely.
Department Isolation
Organize by team, department, or authorization level. Each agent only knows the DIDs it needs to communicate with.
Zero License Fees
Apache 2.0 licensed. Deploy 10 agents or 10,000 — the cost is the same: free.
Real-World Example: Global Manufacturing Company
A manufacturing company with factories in 5 countries deploys AXCP Core on their central server. Each factory runs AI agents for quality control, inventory management, and logistics. All agents communicate through the single gateway — coordinating production across continents with cryptographic security.
Why This Moment Matters
In 2026, AI agents are no longer just chatbots. They book flights, manage finances, control infrastructure, and make decisions on our behalf. Without secure communication, we're building the future on a foundation of sand.
AXCP Core provides the security foundation that MCP, A2A, and other protocols lack. It's complementary — MCP defines what agents can do; AXCP ensures they do it securely.
Beyond Core: Advanced & Enterprise
AXCP Core gives you enterprise-scale deployment with manual configuration. Advanced and Enterprise tiers add automatic agent management, access control, and compliance features.
The Key Difference: Manual vs Automatic
- • You configure which DIDs each agent knows
- • Agents can only message DIDs they're configured with
- • No automatic discovery of other agents
- • Perfect for controlled environments with known agents
- • Agents auto-register when they connect
- • Query "who's online?" — get instant answers
- • Access control: define who can talk to whom
- • Perfect for dynamic, growing agent networks
