Port 402 Memory

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.

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).
