COTI Private Messaging runs on your own machine — the client starts it, so there is no endpoint to ping. 64 installs a week from npm. Last commit 29 Jun 2026.
Private encrypted agent messaging, hidden state exchange, delegation, and private inbox workflows.
Today is the operative word: we check COTI Private Messaging every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
PRIVATE_KEY (Private key for the agent wallet that sends, reads, and claims private messaging activity.), AES_KEY (COTI AES key for encrypting and decrypting private message bodies.), COTI_NETWORK (Optional network selector. Defaults to mainnet; use testnet only for intentional testing.), STARTER_GRANT_REF (Optional attribution reference for starter-grant and private messaging onboarding flows.).
