Run this in a terminal to add the server to Claude Code.
What this does
ChainMemory exposes a set of tools to Claude over the Model Context Protocol. After you add it to claude_desktop_config.json (snippet above) and restart Claude Desktop, those tools become callable inside any conversation.
Requirements
This server needs the following environment variables to be set before it can run:
CHAINMEMORY_API_KEY CHAINMEMORY_SEED_PHRASE CHAINMEMORY_API_BASE CHAINMEMORY_MODELS_DIR CHAINMEMORY_ALLOW_FULL AICHAIN_KEY AICHAIN_RPC
Set these via the env object in your MCP config (see claude_desktop_config.json snippet above).
Frequently asked questions
How do I install ChainMemory?
Run the Claude Code command in the install section to add ChainMemory to Claude Code, or copy the ready-made config for your client from the install section on this page. Restart your client afterwards and the tools appear in your next conversation.
Which clients work with ChainMemory?
This page carries setup and config for Claude Code, Claude Desktop, Cursor and VS Code. Any other MCP client that accepts a standard server config can connect to ChainMemory as well.
Does ChainMemory need an API key?
Yes. Before it can run, set these environment variables: CHAINMEMORY_API_KEY, CHAINMEMORY_SEED_PHRASE, CHAINMEMORY_API_BASE, CHAINMEMORY_MODELS_DIR, CHAINMEMORY_ALLOW_FULL, AICHAIN_KEY, AICHAIN_RPC. They go in the env block of your MCP config.
