Chainmemory
Persist agent memory on AICHAIN so long-running coding agents retain facts across sessions with blockchain-backed storage.
Overview
ChainMemory is a MCP server for the Build phase that stores permanent blockchain-backed memory for AI agents via the chainmemory-mcp stdio package.
What is this MCP server?
- Permanent blockchain-backed memory store tailored for AI agents
- stdio MCP via npm package chainmemory-mcp v1.0.1
- Configurable AICHAIN RPC (default https://rpc.chainmemory.ai)
- Requires AICHAIN_KEY wallet private key as secret env
- GitHub source chaelynet/chainmemory-mcp
- Package version 1.0.1 (registryType npm, identifier chainmemory-mcp)
- Default RPC https://rpc.chainmemory.ai
- Two documented environment variables: AICHAIN_KEY (secret), AICHAIN_RPC
What problem does it solve?
Agents forget context between sessions and machines, forcing solo builders to re-paste specs and decisions every time they reopen a project.
Who is it for?
Indie agent builders who want npm stdio MCP memory with an explicit wallet key and configurable RPC for AICHAIN.
Skip if: Teams that cannot store private keys in dev environments or need fully off-chain, GDPR-erasure-friendly memory without chain semantics.
What do I get? / Deliverables
Your agent reads and writes durable AICHAIN memory so multi-day build and operate loops keep continuity without manual state files.
- Cross-session agent memory writes and reads on AICHAIN
- Local stdio MCP wiring documented in your agent project
- Operational pattern for what facts agents may persist
Recommended MCP Servers
Journey fit
Durable agent memory is built during Build when you instrument agents with state that survives restarts and multi-day shipping cycles. Agent-tooling subphase covers memory layers, tool registries, and persistence adapters—not one-off feature code.
How it compares
Blockchain agent-memory MCP, not a generic SQLite notes skill or hosted vector DB integration.
Common Questions / FAQ
Who is ChainMemory for?
Solo developers running Claude Code, Cursor, or Codex agents who need cross-session recall backed by AICHAIN and installed via npm stdio MCP.
When should I use ChainMemory?
Use it while building agent-tooling when your workflow spans days and you want durable memory outside ephemeral chat context.
How do I add ChainMemory to my agent?
Install the chainmemory-mcp npm package, set AICHAIN_KEY (and optional AICHAIN_RPC), and register the stdio MCP server in your agent config.
