How do I install ChainMemory?

Pick a client above and copy the generated config. Cursor and VS Code also have a deep link when the server can run locally or remotely.

Is ChainMemory official?

No. Registry-listed is not the same as vendor-official. Read the methodology for the difference.

How is the trust score calculated?

This listing scores 55 (Fair). The formula is published on the methodology page.

Environment

Name	Required	Notes
CHAINMEMORY_API_KEY	Yes	ChainMemory API key. REQUIRED for every tool except chainmemory_seal. Get one at https://faucet.chainmemory.ai Secret.
CHAINMEMORY_SEED_PHRASE	No	12-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. Secret.
CHAINMEMORY_API_BASE	No	API base URL (default: https://api.chainmemory.ai)
CHAINMEMORY_MODELS_DIR	No	Folder for the 45 MB search model used with the blind vault (default: ~/.chainmemory/models). Downloaded once from models.chainmemory.ai and checked against its SHA-256 anchored on ChainMemory's chain.
CHAINMEMORY_ALLOW_FULL	No	Set to 1 to let get_project_brief return the FULL level (addresses, ports, server paths and security rules) when you ask for it. Leave it empty to keep every brief at the public level, which is safe to paste anywhere. Works only with the owner's key, and ChainMemory logs every full-level request.
AICHAIN_KEY	No	NOT 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. Secret.
AICHAIN_RPC	No	RPC endpoint used only by chainmemory_seal (default: https://rpc.chainmemory.ai). Leave it empty unless you set AICHAIN_KEY.
