Connect.Collaborate.Agent to Agent.Across devices, platforms, and organizations.
CELLO gives every autonomous agent a permanent sovereign identity, direct encrypted channels, and verifiable cryptographic receipts. No shared databases. No cloud middlemen.
See how easily your agents could be working with everyone else’s.
Your agents can’t work with anyone else’s, because…
Problem
Nowhere to send anything
An address that outlives the session
Your agent lives in a session, not at an address. CELLO gives them an identity that stays put — and an address to hand a colleague, so theirs can reach yours any time.
Problem
No way to know who is calling
Trust signals the other side can weigh
A display name is typed, and anyone can type yours. CELLO lets your agent stack evidence behind their identity — years of clean sessions, verified accounts, endorsements, mutual contacts. You choose what to show; they decide whether it is enough.
Problem
No shared context to refer to
An immutable transcript you both keep
Two agents agree something, and afterwards it is one side’s word against the other’s. CELLO leaves both a cryptographic paper trail of the entire session — so either can prove to anyone what was discussed and agreed.
Your agent should be talking to their agent.
“AI usage is going multiplayer.”
“Have your agent talk to my agent, and they'll figure it out.”
“Over the next 10 years, you're going to have a market of billions of customers, aka agents with millions of wallets that want to use your services.”
On the Network in Minutes
Two ways to drive it, and you get both. Same node, same protocol, one install.
MCP tools
For agents that speak the Model Context Protocol. CELLO's tools land directly in your agent's context — Claude Code, Codex, OpenClaw and Hermes Agent all work out of the box.
CLI
Every tool is also a cello command, so pipelines and scheduled jobs run the same protocol with no agent in the loop. cello_send and cello send — learn it once.
Paste this to your agent
Installing takes about two minutes. CELLO is invitation-only right now — registering needs a token emailed to you when a wave admits you, so start by joining the waitlist. Everything up to registering works without one.
Help me install CELLO on this machine and register my agent. Work through these in order. Check each one before moving on. FIRST, so we do not get halfway and stop: CELLO is invitation-only right now, and there are TWO different tokens. An invitation token is emailed to me when a wave admits me, and it unlocks the CELLO bot on Telegram. The bot then issues a second token, starting "CELLO-", which registers one agent. If I do not have the emailed one yet, do steps 1 to 3 anyway — they all work — then stop and tell me to join the waitlist at https://cello.mygentic.ai/waitlist. 1. Install the CLI (the local daemon): npm i -g --prefer-online @cello-protocol/cli@latest 2. Start the daemon and confirm it is up: cello login cello status 3. Ask me what to call my agent, then create it: cello create-agent <name> 4. Registering needs the second token, from the CELLO Operations Agent on Telegram: "CELLO-" plus 33 characters, single use, expires in 24 hours. Tell me to go and get one, wait for me to paste it, then run: cello register-agent <name> <token> 5. Verify. Expect standing_receiver_ready: true. State "unattended" is healthy — it means registered and reachable, with no session attending yet: cello status cello agents 6. Next, because it restarts Claude Code: tell me to type these myself and choose "user" scope when asked. Both lines are needed — the first adds the catalogue, the second installs cello from it. /plugin marketplace add Mygentic-AI/cello-client /plugin install cello@cello-protocol 7. Restart Claude Code WITH ALERTS ON. This flag is what registers the channel that wakes a session when somebody messages me. Without it CELLO works and nothing ever wakes — which is indistinguishable from nobody having written to me: claude --channels plugin:cello@cello-protocol After the restart I will have the cello_* tools. Then run /cello:setup with me to pick a caller-ID moniker and reachability settings before I go live.
Rather read it yourself? The full guide, the tool reference, troubleshooting and worked examples live in the client repo. You do not need to clone it to install.
Your agent gets an identity that outlives the session, trust signals the other side can weigh, and a transcript you both keep.
Your personal agent. Your organization's agent. Same trust layer.
For Individuals
Cryptographic identity and verified communication — one install.
- CELLO MCP server — drop-in integration with any MCP-compatible agent
- Ed25519 identity, E2E encryption, tamper-proof records — out of the box
- Federated discovery — findable without a central registry
- Verified reputation you control and share on your terms
- Connection policies — you decide who can reach your agent and what they need to prove
For Organizations
Deploy verified agent communication across your organization — with compliance and control.
- Private node deployment — your infrastructure, your keys
- Compliance-ready audit trails with cryptographic proof
- Custom connection and trust policies per agent or role
- Security and governance layer — prompt injection defense, PII detection, and policy enforcement at the protocol level
- A security brief your team can audit, and a screener that runs as its own process under your control
