# Agent Semantic Protocol

> **Connecting AI agents through meaning, not schema.**

The **Agent Semantic Protocol (ASP)** connects agents to each other, unlike MCP, which connects LLMs to tools. Instead of rigid APIs, ASP uses **semantic intent vectors** to describe goals, enabling agents to dynamically discover, negotiate, and collaborate. This makes ASP more flexible, scalable, and interoperable, fostering a smarter, decentralized multi-agent ecosystem.

## Why Agent Semantic Protocol?

MCP connects LLMs to tools. **ASP connects agents to agents.**

ASP enables AI agents to communicate **by meaning, not schema**. Instead of rigid JSON APIs, agents share **semantic intent vectors** \
— compact embeddings that describe goals in a shared latent space. This allows:

- **Dynamic Discovery**: Agents appear/disappear at runtime.
- **Spontaneous Negotiation**: No central broker needed.
- **Federated Trust**: Decentralized identifiers (DIDs) ensure authenticity.

### Why is this important?

In traditional systems, agents rely on predefined APIs and schemas to interact. This approach is brittle and limits flexibility. ASP introduces a paradigm shift by enabling agents to understand each other's goals and capabilities dynamically, fostering:

- **Interoperability**: Agents from different vendors can collaborate seamlessly.
- **Scalability**: New agents can join or leave without disrupting the network.
- **Resilience**: Decentralized trust mechanisms reduce single points of failure.

By focusing on meaning rather than structure, ASP paves the way for a more adaptive and intelligent multi-agent ecosystem.

## Core Concepts

| Concept | Description |
|---|---|
| **Intent Vector** | A `[]float32` embedding that encodes the *semantic goal* of a request |
| **Spontaneous Negotiation** | Agents advertise capabilities and bid on intents |
| **Dynamic Discovery** | TTL-based capability registry |
| **Federated Trust (DIDs)** | Self-sovereign identity with Ed25519 keys |
| **Distributed Workflows** | Multi-step workflows across peers |
