About ChainMemory

ChainMemory is an MCP server published by the GitHub account chaelynet. Verifiable, portable AI memory. Optional vault: encrypted on your machine, 12 words only you hold.

It runs on your own machine: your AI client starts it from the npm package chainmemory-mcp at version 2.10.0.

It asks for 3 secrets: CHAINMEMORY_API_KEY, CHAINMEMORY_SEED_PHRASE and AICHAIN_KEY. Give it a key with the least access that still works.

Version 2.10.0 was published on 10 October 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 9 automated checks on the registry entry and the package code: 6 pass, 2 warn, 0 fail, 1 info. How we check.

What it asks for

VariableRequiredSecretDescription
CHAINMEMORY_API_KEYYesYesChainMemory API key. REQUIRED for every tool except chainmemory_seal. Get one at https://faucet.chainmemory.ai
CHAINMEMORY_SEED_PHRASENoYes12-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.
CHAINMEMORY_API_BASENoNoAPI base URL (default: https://api.chainmemory.ai)
CHAINMEMORY_MODELS_DIRNoNoFolder 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_FULLNoNoSet 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_KEYNoYesNOT 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.
AICHAIN_RPCNoNoRPC endpoint used only by chainmemory_seal (default: https://rpc.chainmemory.ai). Leave it empty unless you set AICHAIN_KEY.
