What it can do
| Tool | What it says it does |
|---|---|
check_postagent_updates | Fetches the live PostAgent agent manifest. Call this before using PostAgent in a new session, after reconnecting the MCP server, or when an installed PostAgent skill may be stale. If the installed skill is older than latestSkillVersion, read latestSkillUrl and follow those instructions for this… |
create_campaign_quote | Quote ONE bulk send to MANY recipients (up to 500): a single template or static document, fulfilled through PostAgent's campaign workflow. Price is an inclusive customer-facing total, locked for 15 minutes. Payment is x402 ONLY. IMPORTANT — KYC WALL: campaigns require the paying wallet to be… |
create_card_checkout | Creates a Stripe-hosted Checkout page for a locked quote and returns a `checkoutUrl` plus a `statusUrl`. Use this as the LAST-RESORT payment rail, when the payer is a human paying by credit card (the agent cannot complete card entry itself). Hand the `checkoutUrl` to the user to open in a browser… |
create_letter | Upload and normalize a FINISHED, ready-to-mail document to PDF. Choose this when the content is final and IDENTICAL for every recipient — including when you mail the same letter to many people (just quote/pay once per recipient with the same documentId). The exact bytes you give are what gets… |
create_mail_quote | Verifies the recipient and sender US addresses and locks a 15-minute USDC price for a documentId. Does not charge or mail anything. Returns a `paymentUrl` (a per-quote x402-payable URL); the preferred way to actually mail the letter is for the agent's wallet to perform an in-band x402 payment… |
create_postcard_art | Upload ONE side of a postcard (front or back) as single-page PDF, PNG, or JPEG artwork. The file is stored VERBATIM — no page-size normalization and no reserved address zone — so you are responsible for the correct trim size plus bleed: 4x6 cards need 4.25"x6.25" artwork, 6x9 needs 6.25"x9.25"… |
create_postcard_quote | Verifies the recipient and sender addresses and locks a 15-minute USDC price for mailing a postcard built from two postcard_art documents (front + back, uploaded via create_postcard_art). Sizes: 4x6 (default), 6x9, 6x11 — postcards always print in full color. US recipients use the strict US… |
create_template | Upload a REUSABLE template containing `{{field}}` placeholders (e.g. `Dear {{name}},` or `Balance due: {{amount}}`). Choose this ONLY when the content must vary per recipient (mail merge) — recipient count is irrelevant, so a single personalized letter belongs here too. If the content is identical… |
get_campaign_status | Returns a campaign's validation/sending progress: status (validating | sent | partial | failed), recipient counts (total / validated / failed), and a failures report URL when some recipients could not be validated. Polling this endpoint also advances the campaign (it releases the campaign for… |
get_mail_job_status | Returns normalized status, carrier/tracking/proof data, and tracking events for a previously created job. |
pay_mail_with_shared_payment_token | Autonomous, no-browser FIAT payment for a locked quote using a Stripe Shared Payment Token (SPT / Machine Payments Protocol). Use this when the agent can mint an SPT on the buyer's behalf and wants to pay by card/wallet without a human in a browser (prefer x402 first if the agent has a… |
prepare_mail_payment | Returns the x402 PAYMENT-REQUIRED challenge for a locked quote so an x402-capable wallet client can sign it. No payment is taken at this step. Probes the canonical per-quote pay URL (`/v1/quotes/:quoteId/pay`). The preferred way to actually pay is for the wallet to perform the standard x402… |
submit_paid_mail_job | Detached-signature fallback for x402 wallets that can emit a standalone PAYMENT-SIGNATURE header. THE PRIMARY/RECOMMENDED PATH is for the agent's wallet to pay the quote's `paymentUrl` in-band (e.g. `npx awal@latest x402 pay <paymentUrl>`); use this tool only if your wallet client cannot do that… |
verify_address | Standalone paid address verification — no mail is sent. Checks whether an address is deliverable and returns the standardized form (US: CASS with ZIP+4; international: per-country matching). Costs a small flat USDC fee per call via x402 (a fraction of a cent vs. mailing). Two-step flow, like the… |
In its maker's words
Print & mail PDF/HTML/Markdown/text/DOCX/images to US addresses; pay per call in x402 USDC on Base.
