Environment variables
  • CHAINMEMORY_API_KEYrequiredsecretChainMemory API key. REQUIRED for every tool except chainmemory_seal. Get one at https://faucet.chainmemory.ai
  • CHAINMEMORY_SEED_PHRASEsecret12-word BIP-39 phrase for the blind vault. Optional: without it the server works exactly as before. With it, sealed:true encrypts a memory on your machine and computes its search vector here, so sealed memories can still be found, and searches send the query's vector instead of its text. Generate one with chainmemory_new_seed. It never leaves your machine and cannot be recovered.
  • AICHAIN_KEYsecretNOT NEEDED for normal use — leave it empty. Only the chainmemory_seal tool reads it, to sign a contract call yourself instead of letting the API anchor the memory (which chainmemory_remember already does). If you do set it, it is a wallet private key: use a dedicated wallet holding only a few AIC, never your main one. No other tool uses it.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.

[![ChainMemory — listed on Serverdex](https://serverdex.io/brand/badge.svg)](https://serverdex.io/server/io-github-chaelynet-chainmemory?utm_source=badge)

Nice for visibility, but GitHub marks README links nofollow, so it doesn't pass authority. Use the HTML badge on your site as well.
