Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

File ships in the package but is absent from the source [пакет] cm-bip39.js:1, [пакет] cm-client.js:1, [пакет] cm-crypto.js:1 и ещё 1

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

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: CHAINMEMORY_API_KEY (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, but sealed:true is unavailable. 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)), 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.). The author declared them in the registry entry; get the values from the project itself.

ChainMemory — questions

Answers built from our own checks of this server.

Why is there no uptime for ChainMemory?
ChainMemory runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package chainmemory-mcp was installed 777 times last week.
How do I connect ChainMemory?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls chainmemory-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use ChainMemory?
The npm package chainmemory-mcp was installed 777 times in the last week. Week over week that is -42%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is ChainMemory open source?
We cannot say either way: written in JavaScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
