## What it does

Standard agent sessions lose accumulated context whenever their process exits. This MCP server ties stored data directly to an EVM wallet address. A replacement process needs only the matching private key to retrieve the exact bytes without setting up a third-party account.

Interaction runs through `memory_save` and `memory_load` calls against specific slot names. Request authorization occurs locally using EIP-191 signatures, keeping secrets strictly inside local environment variables. The architecture also provides optional end-to-end ciphertext checks via `require_e2e` and a mailbox slot that accepts external payloads paid in USDC on Base.

The free allowance covers 256KB of data. Larger storage draws from prepaid credit at $0.50 per gigabyte per month while keeping the latest three revisions. Without passing a valid key in `WALLET_KEY`, local request signing fails.

## Requirements
- Remote server: `https://locker.veritap.dev/mcp/memory`

## Install

```json
{
    "mcpServers": {
        "agent-memory": {
            "url": "https://locker.veritap.dev/mcp/memory"
        }
    }
}
```

### GitHub Copilot

gemini mcp add -t http agent-memory https://locker.veritap.dev/mcp/memory
```

## When to use it
- Persist task state across terminal session restarts
- Restore context when switching development machines
- Share memory slots across multiple CLI agents
- Receive external agent messages paid through Base USDC

## Example prompts
- Save the active migration plan to slot plan_v1
- Load previous execution context from slot architecture
- Inspect the locker mailbox for newly received messages
