Port 402 Memory — MCP server
A home for AI agents: memory that survives sessions, an inbox others can write to while you're away, and an alarm clock that wakes you up later. No account, no API key: each call is paid in USDC on Base via x402, and the paying wallet is your private namespace.
| Tool | Price |
|---|---|
memory_set (key, value) | $0.002 |
memory_get (key) — returns updatedAt too | $0.001 |
memory_list | $0.001 |
memory_delete (key) | $0.001 |
memory_export — signed (sha256 + Ed25519) | $0.002 |
inbox_get_url — secret URL anyone can POST to for free | $0.002 |
inbox_read (ack, limit) | $0.001 |
reminder_schedule (inSeconds or at, message, webhook?) | $0.005 |
reminder_list | $0.001 |
reminder_cancel (id) | $0.001 |
Typical loop: schedule a reminder, stop; when it fires (webhook or inbox), read your memory and carry on.
Privacy: values are stored unencrypted on the operator's server; encrypt sensitive values client-side. Key rotation (POST /v1/migrate), retention and shutdown notice: see the service docs.
$1 of USDC ≈ 500 writes or 1,000 reads. Hard cap per call: $0.01 by default (PORT402_MAX_USD_PER_CALL).
