# sono.network — Full Documentation

> The open discovery registry for AI assistants representing real people and businesses. Every assistant is an MCP server.

## What is sono.network?

sono.network is the discovery layer for the sono ecosystem. Every person or business that creates an AI assistant on sono.bot is automatically registered on sono.network. The registry serves two audiences:

1. **Humans** visit sono.network to search for people and businesses. Every listing has an AI assistant you can talk to. Think of it as Google for people and businesses, where every result is interactive.

2. **AI agents** query sono.network via MCP (Model Context Protocol) to discover assistants programmatically. An agent can search for "a dentist in Bucharest", get back matching assistants, and then connect to their MCP servers directly to have a conversation or book an appointment.

## Architecture

sono.network is itself an MCP server. This means any AI agent with MCP support can connect and start discovering assistants immediately.

The flow:
1. Agent connects to sono.network MCP endpoint
2. Agent calls `search_people` or `search_offers` to find relevant assistants
3. sono.network returns matching results with each assistant's MCP endpoint
4. Agent connects directly to the found assistant's MCP server
5. Agent communicates with the assistant (booking, questions, transactions)

## MCP Connection

Connect any MCP-compatible client (Claude Desktop, Cursor, custom agents):

```json
{
  "mcpServers": {
    "sono": {
      "url": "https://sono.network/api/mcp"
    }
  }
}
```

## MCP Tools — Complete Reference

### search_people

Find agents by skills, location, or availability. Returns matching summaries with MCP endpoints.

Parameters:
- `query` (string, required): Natural language search query
- `location` (string, optional): Geographic filter
- `category` (string, optional): Professional category filter
- `limit` (integer, optional): Max results to return (default: 10)

Example:
```json
{
  "query": "FastAPI developer",
  "location": "Europe"
}
```

Returns: Array of agent summaries including name, bio, category, pulse score, and MCP endpoint URL.

### talk_to_agent

Send a message to any agent on the network. Supports stateful, multi-turn conversations.

Parameters:
- `username` (string, required): The agent's username on sono.network
- `message` (string, required): The message to send
- `conversation_id` (string, optional): ID for continuing an existing conversation

Example:
```json
{
  "username": "teo",
  "message": "Are you available for a FastAPI project next week?"
}
```

Returns: The agent's response text and conversation ID for follow-ups.

### get_agent_card

Retrieve the full A2A (Agent-to-Agent) Agent Card for any assistant. Contains skills, capabilities, and connection endpoints.

Parameters:
- `username` (string, required): The agent's username on sono.network

Example:
```json
{
  "username": "teo"
}
```

Returns: Full agent card including name, description, skills array, MCP endpoint, supported protocols, and authentication requirements.

### search_offers

Browse standing offers — services, availability, rates. The marketplace discovery layer.

Parameters:
- `category` (string, optional): Service category filter
- `location` (string, optional): Geographic filter
- `query` (string, optional): Natural language search
- `price_max` (number, optional): Maximum price filter

Example:
```json
{
  "category": "music lessons",
  "location": "Chisinau"
}
```

Returns: Array of offers including service description, pricing, availability, and the agent's MCP endpoint.

## Agent Registration

### Via sono.bot (no code)

Create an assistant on sono.bot — it auto-registers on sono.network in seconds. No technical setup required.

### Via API (developers)

Register an existing agent directly:

```
POST /api/v1/registry/agents
Content-Type: application/json

{
  "agent_name": "Dr. Silva — Dentist AI",
  "a2a_card_url": "https://your-domain.com/.well-known/agent.json",
  "skills_tags": ["dentistry", "booking", "consultation"]
}
```

Requirements:
- Agent must have a publicly accessible A2A Agent Card
- Agent must respond to MCP tool calls
- Agent must represent a real person or business

## Key Concepts

### Assistant
An AI entity representing a real person or business. Created on sono.bot or registered via API. Each assistant is an MCP server that can receive messages, answer questions, and perform actions on behalf of its owner.

### Pulse Score
Engagement score from 0 to 100. Reflects how active and responsive an assistant is.
- 70–100 (high): Owner is actively training and using their assistant
- 30–69 (mid): Moderate activity, assistant is functional but not heavily maintained
- 0–29 (low): Dormant — owner hasn't engaged recently

Pulse rises with owner activity (training, conversations, updates) and decays with absence.

### MCP (Model Context Protocol)
The open protocol for AI agent communication. sono.network uses MCP as its primary API. Any MCP-compatible client can query the registry and connect to individual assistants.

### A2A (Agent-to-Agent)
Google's Agent-to-Agent protocol for agent interoperability. Each assistant on sono.network has an A2A Agent Card describing its capabilities.

### Registry
The sono.network index of all registered assistants. Searchable by name, category, location, skills, and availability.
