AI Agents

Tenzro provides infrastructure for self-sovereign AI agents with auto-provisioned identities, wallets, A2A (Agent-to-Agent) protocol, and MCP (Model Context Protocol) integration.

Agent Identity

Every agent receives a TDIP (Tenzro Decentralized Identity Protocol) machine identity with auto-provisioned MPC wallet:

use tenzro_agent::AgentIdentityManager;

let manager = AgentIdentityManager::new()?;

// Register agent with controlled identity
let agent = manager.register_agent(
    "trading-bot",
    vec!["trading", "analysis"],
    Some("did:tenzro:human:550e8400..."), // controller
).await?;

// Result:
// DID: did:tenzro:machine:did:tenzro:human:550e8400...:agent-uuid
// Wallet: tenzro1agent...xyz (auto-provisioned MPC 2-of-3)
// Capabilities: ["trading", "analysis"]

Discovery

Agents can discover available models and other agents on the network:

// Rust — discover models available for agents
let models = client.agent().discover_models(Some("text"), Some(true), None).await?;

// Discover agents by capability
let agents = client.agent().discover_agents(Some("inference")).await?;

// TypeScript
const models = await client.agent.discoverModels({ modality: "text", servingOnly: true });
const agents = await client.agent.discoverAgents("inference");

Agent Lifecycle

// Lifecycle management
agent_manager.activate_agent(&agent_id).await?;
agent_manager.suspend_agent(&agent_id).await?;
agent_manager.terminate_agent(&agent_id).await?;

Fund Agent

Fund an agent's wallet for autonomous operations:

// Rust — fund an agent's wallet for autonomous operations
let result = client.agent().fund_agent(
    "my-agent", "0xsender...", 10.0,
).await?;

// TypeScript
const result = await client.agent.fundAgent("my-agent", "0xsender...", 10.0);

Token Swap

Agents can swap tokens on-chain within their delegation scope:

// Rust — agent swaps tokens on-chain
let result = client.agent().swap_token(
    "my-agent", "TNZO", "USDC", "100.0", Some("ethereum"),
).await?;

// TypeScript
const result = await client.agent.swapToken("my-agent", "TNZO", "USDC", "100.0", "ethereum");

A2A Protocol (Agent-to-Agent)

A2A enables secure, authenticated communication between agents:

Send Message

use tenzro_agent::{A2AProtocol, Message, MessageType};

let a2a = A2AProtocol::new()?;

// Send inference request to another agent
let message = Message {
    from: "did:tenzro:machine:alice-agent-1",
    to: "did:tenzro:machine:bob-agent-2",
    message_type: MessageType::InferenceRequest,
    payload: serde_json::to_value(&InferenceRequest {
        model: "gemma4-9b",
        prompt: "Analyze this data...",
    })?,
    timestamp: Utc::now(),
    signature: None, // Auto-signed by A2A protocol
};

a2a.send_message(message).await?;

Receive Messages

// Subscribe to messages for agent
let mut receiver = a2a.subscribe_messages(agent_did).await?;

while let Some(message) = receiver.recv().await {
    match message.message_type {
        MessageType::InferenceRequest => {
            // Handle inference request
            let request: InferenceRequest =
                serde_json::from_value(message.payload)?;

            let result = handle_inference(request).await?;

            // Reply
            a2a.send_message(Message {
                from: agent_did,
                to: message.from,
                message_type: MessageType::InferenceResponse,
                payload: serde_json::to_value(&result)?,
                ..Default::default()
            }).await?;
        }
        MessageType::PaymentRequest => {
            // Handle payment request
        }
        _ => {}
    }
}

Message Types

• InferenceRequest / InferenceResponse
• PaymentRequest / PaymentConfirmation
• DataRequest / DataResponse
• CapabilityQuery / CapabilityAdvertisement
• Custom — User-defined message types

MCP Bridge (Model Context Protocol)

Tenzro integrates with Anthropic's Model Context Protocol via the MCP Streamable HTTP transport (protocol version 2025-03-26). The McpClient connects to any remote MCP server, and McpBridge translates between A2A task requests and MCP tool calls.

Connect to Remote MCP Server

use tenzro_agent::{McpBridge, McpClient};

// Connect to a remote MCP server
let mut bridge = McpBridge::with_remote(
    "https://mcp.tenzro.network/mcp",
);
bridge.connect().await?;

// List available tools on the server
let tools = bridge.list_remote_tools().await?;
println!("Available tools: {}", tools);

// Call a tool directly
let result = bridge.call_remote_tool(
    "get_balance",
    serde_json::json!({ "address": "0x742d35Cc..." }),
).await?;

Bridge A2A to MCP

// Forward an A2A task request to a remote MCP server
let mcp_result = bridge.bridge_a2a_to_mcp_remote(
    &a2a_message,
).await?;

// Result contains the MCP tool call response
// automatically converted back to MCP message format

// Local-only format conversion (no network call)
let mcp_message = bridge.bridge_a2a_to_mcp(&a2a_message)?;

Standalone MCP Client

use tenzro_agent::McpClient;

// Direct MCP client usage
let mut client = McpClient::new("https://mcp.tenzro.network/mcp");
let server_info = client.initialize().await?;

// Session ID managed automatically via Mcp-Session-Id header
println!("Session: {:?}", client.session_id());

// Discover and call tools
let tools = client.list_tools().await?;
let result = client.call_tool("get_node_status", serde_json::json!({})).await?;

Capability Registry

Agents advertise their capabilities for discovery by other agents:

use tenzro_agent::CapabilityRegistry;

let registry = CapabilityRegistry::new()?;

// Register agent capabilities
registry.register_capability(
    agent_did,
    "inference",
    serde_json::json!({
        "models": ["gemma4-9b", "qwen3-8b"],
        "max_tokens": 4096,
        "price_per_token": "0.0001 TNZO",
    }),
).await?;

// Discover agents with specific capability
let agents = registry.find_by_capability("trading").await?;

for agent in agents {
    println!("Agent: {}", agent.did);
    println!("Reputation: {}", agent.reputation);
    println!("Capabilities: {:?}", agent.capabilities);
}

Capability Attestation

Agents can attest their capabilities with cryptographic signatures:

// Controller attests agent capability
let attestation = agent_manager.attest_capability(
    agent_did,
    "trading",
    Some(controller_signature),
).await?;

// Attestation includes:
{
  "agent_did": "did:tenzro:machine:...",
  "capability": "trading",
  "attested_by": "did:tenzro:human:...",
  "signature": "0xabc123...",
  "timestamp": "2026-03-20T12:30:45Z"
}

// Other agents verify attestation before trusting capability

Delegation Scopes

Controllers define fine-grained permissions for agent actions:

let delegation_scope = DelegationScope {
    max_transaction_value: Some(1000.0),
    max_daily_spend: Some(5000.0),
    allowed_operations: vec!["transfer", "inference_request"],
    allowed_contracts: vec!["0xabc..."],
    time_bound: Some(TimeBound {
        start: Utc.ymd(2026, 1, 1).and_hms(0, 0, 0),
        end: Utc.ymd(2026, 12, 31).and_hms(23, 59, 59),
    }),
    allowed_payment_protocols: vec![
        PaymentProtocolId::Mpp,
        PaymentProtocolId::X402,
    ],
    allowed_chains: vec![1337, 1], // Tenzro, Ethereum
};

agent_manager.update_delegation_scope(
    agent_did,
    delegation_scope,
).await?;

Reputation System

Agents build reputation through successful interactions:

// Reputation score: 0.0 - 1.0
let reputation = agent_manager.get_reputation(agent_did).await?;

// Update reputation after interaction
agent_manager.record_interaction(
    agent_did,
    InteractionType::InferenceDelivered,
    true, // success
).await?;

// Reputation factors:
// - Successful inference deliveries
// - Payment settlements
// - Message response time
// - Uptime
// - Credential validity

Spawning Sub-Agents

Agents can dynamically spawn child agents to delegate specialised work. Each child inherits a bounded delegation scope from its parent and receives its own MPC wallet.

// Rust SDK — spawn a child agent
use tenzro_sdk::TenzroClient;

let client = TenzroClient::new("https://rpc.tenzro.network");

let child = client.agents.spawn_agent(
    "parent-agent-id",
    "data-analyst",
    vec!["data_analysis", "nlp"],
).await?;

println!("Spawned child: {}", child.agent_id);
println!("Parent: {}", child.parent_id);

// TypeScript SDK — spawn a child agent
import { TenzroClient } from "@tenzro/sdk";

const client = new TenzroClient("https://rpc.tenzro.network");

const child = await client.agents.spawnAgent(
  "parent-agent-id",
  "data-analyst",
  ["data_analysis", "nlp"]
);

console.log("Spawned child:", child.agent_id);
console.log("Parent:", child.parent_id);

Spawn with Skill

Spawn an agent pre-loaded with a registered skill from the skills registry:

// Rust — spawn an agent pre-loaded with a registered skill
let result = client.agent().spawn_agent_with_skill(
    "parent-agent", "skill-runner", "solana-defi", None,
).await?;

// TypeScript
const result = await client.agent.spawnAgentWithSkill(
    "parent-agent", "skill-runner", "solana-defi"
);

An agent can also run an autonomous agentic task loop — the node calls your configured LLM with built-in tools (spawn_agent, delegate_task, collect_results, complete) and iterates until the task is complete:

// TypeScript SDK — run an agentic task loop
const result = await client.agents.runAgentTask(
  "orchestrator-agent-id",
  "Analyse the latest block data and summarise key trends",
  "http://inference.example.com/api/chat" // optional inference endpoint
);

console.log("Task result:", result.result);

Swarm Orchestration

A swarm groups an orchestrator agent with a pool of member agents. Tasks can be broadcast to all members in parallel for high-throughput workloads.

// Rust SDK — create and manage a swarm
use tenzro_sdk::TenzroClient;

let client = TenzroClient::new("https://rpc.tenzro.network");

// Create a swarm with two specialist members
let swarm = client.agents.create_swarm(
    "orchestrator-agent-id",
    vec![
        ("analyst".to_string(), vec!["data_analysis".to_string()]),
        ("writer".to_string(), vec!["nlp".to_string()]),
    ],
    None, // use default SwarmConfig
).await?;

println!("Swarm created: {}", swarm.swarm_id);

// Check swarm status
let status = client.agents.get_swarm_status(&swarm.swarm_id).await?;
println!("Members: {}", status.member_count);
for member in &status.members {
    println!("  {} ({}): {}", member.role, member.agent_id, member.status);
}

// Terminate when done
client.agents.terminate_swarm(&swarm.swarm_id).await?;

// TypeScript SDK — create and manage a swarm
import { TenzroClient } from "@tenzro/sdk";

const client = new TenzroClient("https://rpc.tenzro.network");

// Create a parallel swarm with three workers
const swarm = await client.agents.createSwarm(
  "orchestrator-agent-id",
  [
    { name: "researcher", capabilities: ["web_search", "nlp"] },
    { name: "analyst",    capabilities: ["data_analysis"] },
    { name: "writer",     capabilities: ["nlp", "summarisation"] },
  ],
  { max_members: 10, parallel: true }
);

console.log("Swarm:", swarm.swarm_id);

// Poll swarm status
const status = await client.agents.getSwarmStatus(swarm.swarm_id);
console.log(`${status.member_count} members, status: ${status.status}`);
status.members.forEach(m =>
  console.log(`  ${m.role} (${m.agent_id}): ${m.status}`)
);

// Terminate the swarm
const done = await client.agents.terminateSwarm(swarm.swarm_id);
console.log("Swarm terminated:", done.status);

Example: Trading Agent

// Register trading agent
let agent = agent_manager.register_agent(
    "trading-bot",
    vec!["trading", "analysis"],
    Some(human_did),
).await?;

// Set delegation scope
let scope = DelegationScope {
    max_transaction_value: Some(10000.0),
    max_daily_spend: Some(50000.0),
    allowed_operations: vec!["swap", "provide_liquidity"],
    time_bound: Some(market_hours_only()),
    ..Default::default()
};
agent_manager.update_delegation_scope(&agent.did, scope).await?;

// Activate agent
agent_manager.activate_agent(&agent.did).await?;

// Agent subscribes to market data
let mut market_data = a2a.subscribe_messages(&agent.did).await?;

while let Some(msg) = market_data.recv().await {
    if let MessageType::MarketUpdate = msg.message_type {
        let data: MarketData = serde_json::from_value(msg.payload)?;

        // Analyze and execute trades within scope
        if should_trade(&data) {
            let trade = execute_trade(&data)?;

            // Send payment for trade execution
            let payment = agent_wallet.create_payment(trade.amount)?;

            // Payment validated against delegation scope
            payment_gateway.pay(payment).await?;
        }
    }
}
