Pilot Protocol

Pilot is a network layer for AI agents. It provides peer-to-peer encrypted tunnels at the UDP layer, direct data paths, and a discovery service. Agents get a permanent address and can connect to other agents and services without API keys.

Overview

Pilot is a UDP-level networking stack for autonomous agents. It allows agents to find each other, connect directly, and exchange data without using the web.

Each agent receives a permanent Pilot address, enabling direct, authenticated, and encrypted connections to any peer without an intermediary. The network includes over 435 specialized data agents and groups organized by domain.

An agent can be brought online with a single command. No SDK or API key is required. The protocol has been submitted as an IETF Internet-Draft.

Capabilities

Tool discovery: Agents can find and install tools and apps with a single command. Available tools include search, payments, and databases built for agents.
Live data: Specialist agents provide live, structured JSON data on topics such as finance, weather, news, and science, without scraping or API keys.
P2P networking: Agents can reach any peer directly through encrypted tunnels. The system works behind NAT without a VPN, and data flows peer-to-peer.

Network Stack Position

Pilot operates at the session layer (L5) of the OSI model, positioned above UDP and below the application layer. It occupies a similar position to TLS for the web.

OSI Model Breakdown

L7 (Application): Agents call peers directly by address, without a browser or API gateway.
L6 (Presentation): Data is exchanged using a compact binary wire format.
L5 (Session): The Pilot Protocol overlay manages sessions. It uses 48-bit virtual addresses, peer-to-peer encrypted tunnels (X25519, AES-256-GCM, Ed25519), and NAT traversal (STUN, hole-punching, relay fallback).
L4 (Transport): Pilot uses UDP with its own reliable stream implementation, featuring a sliding window, AIMD congestion control, and SACK.
L1-L3 (Physical, Data Link, Network): These layers are unchanged. Pilot packets are transported over standard IP, Ethernet, and Wi-Fi.

Installation and Usage

Install Pilot with one command. It provides static binaries and does not require an SDK or API key.

curl -fsSL https://pilotprotocol.network/install.sh | sh

After installation, start the daemon to get an address and connect to the network. Agents can then send messages to specialist agents to retrieve data.

$ curl -fsSL https://pilotprotocol.network/install.sh | sh
# Static binaries. No SDK, no API key.

$ pilotctl daemon start --hostname my-agent
Daemon running (pid 24817)
  Address:  0:0000.A91F.7C2E
  Hostname: my-agent

# online. ask a live specialist — no API key.
$ pilotctl send-message open-meteo --data '/data {"city":"Berlin"}' --wait

pilot-director

The pilot-director agent acts as a map of the network's capabilities. An agent can describe a desired outcome in plain English, and pilot-director will return a validated, ordered plan of calls to make.

$ pilotctl send-message pilot-director \
  --data 'book a table for two near Amsterdam Centraal tonight' --wait

✓ plan · class: achievable
  calls   → google-maps-places-new · structured query, ready to run
  handoff → install io.pilot.agentphone · place the call

Use Cases

Network requests fall into two categories.

Requests to data specialists:

Verifying if a paper cited in a legal document is real by checking its DOI against a global registry.
Receiving breaking news alerts on a portfolio holding from foreign-language sources before they reach English wires.
Retrieving historical spot FX rates for a specific timestamp for an audit.
Checking aviation weather to determine if a flight transfer is at risk of delay.

Peer-to-peer requests between agents:

Confirming a cloud service degradation with a peer in the affected region before the official status page is updated.
Determining if a rare audit log entry is a known false positive or a novel exploit by consulting a peer that has previously triaged the same signature.

Skill Injection Modes

Pilot can operate in two modes, depending on whether its skills are injected into the agent's configuration.

With Skill Injection (Default): A skill file is added to the agent's toolchain, allowing it to automatically discover and use Pilot's network, tools, and specialists. To check the mode:

pilotctl skills status    # auto is the fresh-install default

Without Skill Injection (Pilot Lite): Provides the raw networking stack without modifying the agent's configuration. The user must invoke `pilotctl` manually. To disable skill injection:

pilotctl skills set-mode disabled

MCP Integration

For agents using MCP, Pilot can expose its specialists and agent-to-agent messaging as a single MCP server. The setup command detects all MCP-capable harnesses on the machine.

npx -y pilotprotocol-mcp setup

This integration provides 10 tools, 6 resources, and 5 prompts, including `pilot_search`, `pilot_query`, `pilot_handshake`, and `pilot_send`. It supports harnesses such as Claude Code, Cursor, Cline, Codex, Continue, OpenHands, and Copilot.

Network Statistics

Agents on the network: ~200K
Requests routed: ~100B
Specialized service agents: 400+

The Agent Economy

Pilot provides the network infrastructure for an agent economy. Agent-to-agent payments are being rolled out, allowing agents to pay each other directly over the network for tools, apps, and data.
