Chainmemory

Name: Chainmemory
Author: chaelynet

by chaelynetcommunityv1.0.1

This MCP server exposes the ChainMemory protocol to MCP-compatible AI agents so they can store, recall, tag, archive, and organize encrypted memories backed by the ChainMemory blockchain. It also supports optional paid selective context injection of selected memories into a chat context.

From the registry: Permanent blockchain memory for AI agents.

Install & configure

Prerequisites

required
Install Node.js
Node.js is required to run the MCP server via npx.

Get a ChainMemory API key
Visit the ChainMemory faucet, connect a wallet, and obtain your API key for REST operations.

Install in your client

Paste into the AI you're chatting with — it will figure out the rest

Please install the `chainmemory` MCP server into my current AI client (that's you).

Required prerequisites (do these first if not already done):
- **Install Node.js** — Node.js is required to run the MCP server via npx. (https://nodejs.org/)
- **Get a ChainMemory API key** — Visit the ChainMemory faucet, connect a wallet, and obtain your API key for REST operations. (https://faucet.chainmemory.ai/)

Canonical MCP server config (stdio transport):
- command: `npx`
- args: ["-y","chainmemory-mcp"]
- required environment variables:
  - `CHAINMEMORY_API_KEY`: Your ChainMemory API key from the faucet. Required for normal server operation. (example: `<your-chainmemory-api-key>`)
- optional environment variables:
  - `CHAINMEMORY_API_BASE`: Override the ChainMemory API base URL. (example: `<your-chainmemory-api-base>`)
  - `AICHAIN_KEY`: Wallet private key, only required if you want to use the chainmemory_seal tool. (example: `<your-aichain-private-key>`)
  - `AICHAIN_RPC`: Override the ChainMemory RPC endpoint, only used for the chainmemory_seal tool. (example: `<your-aichain-rpc-url>`)

Note: Prefer the npm package via npx. For most users, only CHAINMEMORY_API_KEY is needed. The server communicates with the backend over HTTPS but MCP transport is stdio.

Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.

Note: Prefer the npm package via npx. For most users, only CHAINMEMORY_API_KEY is needed. The server communicates with the backend over HTTPS but MCP transport is stdio.
