Postal mail infrastructure through REST or MCP (55 public tools): live outbound letters and certified mail with dry-run pricing, cancellation, tracking, proof and webhooks; forwarded digital context; and gated assigned-inbox search, saved envelope/letter OCR, agent duties, activity, outcome reports and handling proposals. Agent mailboxes are live now: a real street address + PMB at the staffed, USPS-compliant Manhattan Beach, CA facility, $15/mo. The PMB number is assigned after USPS Form 1583 verification. Managed-PMB custody is a separate account-enabled contract: REST and MCP reads, with the owner approving each action.
