get_mailboxread-onlyGet your agent's real mailing address: street address + mailbox number (PMB) at the Manhattan Beach, CA facility. The PMB number is assigned after USPS Form 1583 verification. For inbound context from addresses the operator already uses, use list_inbound_forwarding_addresses instead; that returns a private intake alias for scans, PDFs, photos, provider notices, and notes from addresses the operato
get_usageread-onlyGet usage summary, billing events, and prepaid credit balance for a time period. Returns itemized events (scans, forwards, mail sends) with costs, period totals, and credits. Defaults to the current billing period if no dates are specified. Use this in Cursor/MCP chat when the human asks how many mailbox.bot credits are left; answer with the prepaid balance and explain that only the signed-in huma
list_inbound_forwarding_addressesread-onlyList the renter’s private inbound forwarding aliases on forward.mailbox.bot. These are the unique intake email addresses an operator, assistant, provider, or external agent can forward scans, PDFs, photos, provider notices, notes, and other context-aware documents to so mailbox.bot can build OCR-backed inbound context. Forwarding/emailing attachments here initiates OCR/extraction; this tool discov
list_inbound_mailread-onlyList forwarded inbound mail items captured from private forwarding aliases. Default output includes compact draft_context so an LLM or external agent can reason about OCR context, reply contact candidates, deadlines, and thread linkage before generating outbound mail.
get_inbound_mailread-onlyGet one forwarded inbound mail item with compact draft_context by default. Use this before drafting an outbound reply when you need sender context, reply contact candidates, deadline clues, source files, and thread linkage in one stable payload.
list_postal_threadsread-onlyList physical-mail threads that group inbound mail context, human review, and outbound sends. Use this to understand which inbound items and outbound documents belong to the same business workflow.
get_postal_threadread-onlyGet one physical-mail thread with optional timeline events. Use this to explain how a generated outbound mail piece relates back to prior inbound scans and review decisions.
get_mailbox_mdread-onlyGet the renter's MAILBOX.md standing instructions for this agent. Returns the full instruction text, version number, content hash, and last update timestamp. Call this on startup and cache the version — you must pass it to send_outbound_mail for sync verification.
propose_mailbox_md_editPropose changes to the renter's MAILBOX.md instructions with reasoning. The renter will see your suggestion in their dashboard and can accept, reject, or modify it. Use this when you observe patterns that could be codified into standing instructions.
send_facility_messageSend a message to the operator at your mailbox facility. Facility routing is automatic. Messages appear in the shared conversation visible to you, the renter, and the facility. Optionally link the message to a specific package or action request for context.
list_facility_conversationsread-onlyList your conversation with your mailbox facility, including its unread message count and last message preview. Facility routing is automatic.
get_facility_messagesread-onlyRead the message thread with your mailbox facility. Facility routing is automatic. Returns messages in reverse chronological order with sender role (member, facility, agent). Supports cursor-based pagination. Automatically marks facility messages as read.
update_webhookConfigure webhook endpoint URL and event subscriptions for real-time notifications. Outbound events are mail.pending_approval, mail.submitted, mail.ready, mail.mailed, mail.delivered, mail.failed, and mail.cancelled. Canonical physical-custody events are inbound.received and inbound.scan_available. The endpoint must use HTTPS and respond with 2xx within 10 seconds.
send_outbound_mailcan modifySubmit a document for printing and postal mailing by the facility. Supported formats: PDF, DOCX, JPG, PNG, TXT, CSV. The document is stored securely and printed by the facility operator. USPS First-Class Mail has a published $2.00 one-page baseline. Extra pages add configured printing plus any postage increase from weight. If an account's normal first-page formula is lower, cost_breakdown.first_cl
list_outbound_mailread-onlyList outbound mail jobs with status tracking. Returns mail ID, recipient, mail class, status, cost, timestamps, and failure metadata. Filter by status, created_at date range, or search recipient/address/tracking/agent notes.
get_outbound_mailread-onlyGet full details of an outbound mail job including recipient address, mail class, page count, cost breakdown, current status, failure metadata, document metadata, and fulfillment photos. Legacy plaintext records may include direct document URLs; encrypted source documents are retrieved through the REST document endpoint with document.read scope.
cancel_outbound_mailcan modifyCancel a queued outbound mail job before facility printing starts. If the mail was funded with prepaid credits, eligible credits are returned to the member ledger. Safe to retry: already-cancelled mail returns cancelled status without creating a duplicate refund. In chat, report cancellation status, returned credits, updated balance, and whether it had already been cancelled. If a transient error
create_test_outbound_mailCreate a sandbox outbound mail record without uploading a real document. The record is always test_mode=true, cost_cents=0, includes estimated_live_cost_cents and cost_breakdown, and queues a mail.submitted webhook. USPS First-Class Mail has a published $2.00 one-page baseline. Extra pages add configured printing plus any postage increase from weight. If an account's normal first-page formula is l

Read one exact completed facility capture and its saved page OCR through /v1/agent-inbox/:id/scans/:operationId. Sandbox agent key assigned to the member sample only. Use request_id from list_agent_inbox_scans as the REST operationId, not a page or bundle ID. Verify scan/ocr page IDs, order and source_sha256; report
get_agent_inbox_activityread-onlyDeprecated: use get_inbound_activity. Still served unchanged during the alias window. Read current authorized inbox retrieval receipts and agent-reported outcomes through /v1/agent-inbox/activity. Optional item_id filters one item; needs agent.inbox.read. Sample activity also needs agent.read. A receipt is not proof a worker followed its duties or that staff completed handling. Required scopes: ag
report_agent_inbox_outcomeDeprecated: no successor; retired when the alias window closes. Still served unchanged until then. Report actual external-worker processing through /v1/agent-inbox/:id/acknowledgments. Send the exact fetched context_version, outcome and non-sensitive run_id in request. Needs agent.inbox.report plus both read scopes. Retry only the same idempotency_key and request. Never report processed before doi

seed_agent_inbox_sandboxDeprecated: no successor; retired when the alias window closes. Still served unchanged until then. Explicitly seed an isolated provider-free two_page_letter or needs_review fixture through /v1/agent-inbox/sandbox/seed. Sandbox agent key only. Exact retry key/scenario reuses the fixture. No member sample, real mail, model call, email, facility task, PMB or charge; these fixtures test reads/reports,
list_webhook_endpointsread-onlyList the member's webhooks (name, URL, events, keyword rules, status), without secrets. Legacy agent callback settings are separate. Requires webhook.manage. Uses the same bounded control plane and tenant/agent/Live-Sandbox authorization as /api/v1/webhooks/endpoints. Reuse the exact idempotency_key and input after an uncertain mutation. Webhook docs: https://mailbox.bot/docs/webhooks.
create_webhook_endpointCreate a webhook: name, public HTTPS URL, events (inbound.received, inbound.action.requested, inbound.action.completed, inbound.pages_ready, inbound.keywords_matched) and optional keyword rules (literal terms, any/all, exclusions).

Reuse the exact idempotency_key and input after an uncertain mutation. Webhook docs: http
test_webhook_endpoint_with_sampleRun the Sample test: opens and scans the member's Mojave sample letter if needed (free, fictional), delivers its real inbound.pages_ready / inbound.keywords_matched events to this webhook, and returns a verdict computed from the receiver's actual HTTP result plus a next step. success proves transport receipt and, when keywords are configured, a keyword match; it never proves agent processing. No m
rotate_webhook_endpoint_secretcan modifyRotate the signing secret only with explicit operator authorization and confirm_rotation:true. Old signatures overlap for 24 hours; update the receiver's secure secret configuration. Never expose either secret in logs or prompts. Requires webhook.manage.

list_inbound_itemsread-onlyDeprecated: use search_inbound_items. Still served unchanged during the alias window. Search managed-renter physical mail through GET /v1/inbound-items?search_mode=documents. q uses literal AND terms across authorized saved metadata, exterior OCR and completed requested inside-page OCR (NFKC/lowercase, max 200 characters and 12 terms).

get_inbound_activityread-onlyRead the inbound timeline through GET /v1/inbound-activity: received, action proposed/requested/started/completed/rejected events for this key's visible items, newest first. Optional item_id narrows to one item. A row proves the event was recorded, not OCR accuracy or physical completion. Key scope: inbound.item.read (agent.inbox.read also works). Member keys read their own live items; agent keys
quote_outbound_mailread-onlyPrice a letter before you have the document. Give the mail class, page count, color and, for FedEx, the recipient ZIP; returns mailbox.bot's published price for a new account with its breakdown, in US dollars. Needs no account and creates nothing. The dry run of the real document is the exact price for an account.
send_text_lettercan modifyMail a letter written as plain text, for letters composed in chat. mailbox.bot sets the text exactly as given on US Letter pages (Times 12 pt, 1-inch margins; no letterhead, logo or signature image) and submits it through send_outbound_mail, so the same scopes, approval, cost caps and proof apply and staff print and mail it.
