What is the ChainMemory MCP Server?

ChainMemory is an MCP integration. Verifiable, portable AI memory. Optional vault: encrypted on your machine, 12 words only you hold.

Packages and local setup

The published npm package is chainmemory-mcp, version 2.9.1. Its declared MCP transport is stdio.

The package declares CHAINMEMORY_API_KEY (required): ChainMemory API key. REQUIRED for every tool except chainmemory_seal. Get one at https://faucet.chainmemory.ai; CHAINMEMORY_SEED_PHRASE: 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.; CHAINMEMORY_API_BASE: API base URL (default: https://api.chainmemory.ai); CHAINMEMORY_MODELS_DIR: 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.; AICHAIN_KEY: 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.; AICHAIN_RPC: RPC endpoint used only by chainmemory_seal (default: https://rpc.chainmemory.ai). Leave it empty unless you set AICHAIN_KEY..

Before connecting

Check the maintainer’s instructions for account access, authentication and the supported client configuration. Once connected, inspect the tools your client receives and try a small task that matches the server’s stated purpose. The registry description does not include a verified, complete tool list.
