Comprehensive Model Context Protocol server for managing Home Assistant through AI assistants.
Nothing to run from here
Postagent is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

Postagent costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http postagent-mcp https://api.postagent.sh/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
14 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

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 turn; if updateRequired is true, do not perform paid or irreversible PostAgent actions until the user up

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 printed. Use create_template instead only when the content must vary per recipient via {{fields}}. Returns
| Parameter | Type | Required | Notes |

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 for everyone, use create_letter instead (this tool rejects input with no {{fields}}). Returns a doc

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 against that URL (e.g. npx awal@latest x402 pay <paymentUrl>). The MCP submit_paid_mail_job tool is a

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 and pay; payment is asynchronous — once they finish, the letter is created automatically by Stripe's w

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 USDC-on-Base wallet; this is the autonomous fiat alternative). CHARGES MONEY AND IS IRREVERSIBLE: the server auth

| userConfirmed | boolean | yes | Must be true. Set this only after the human user explicitly approved sending physical mail at the quoted price. |
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 in-band handshake against paymentUrl; this tool is for inspection or for the detached-signature flow via `

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. Charges the agent in USDC on Base mainnet and creates a physical letter for printing and mailing. THIS

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", 6x11 needs 6.25"x11.25" (0.125" bleed on each edge). The selected delivery method prints the recipient a

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 address shape; INTERNATIONAL recipients are supported on 4x6 only (set to.country to the 2-letter ISO code
| Parameter | Type | Required | Notes |
|---|---|---|---|
| frontDocumentId | string | yes | documentId of the FRONT artwork (kind postcard_art). |

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 mail rails: call WITHOUT paymentSignature to get the 402 challenge and paymentUrl (preferred: have

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 identity-verified with PostAgent. Verification is operator-run, not self-serve: until the wallet is verifi

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.

Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither: the repository linked on this page is where this record was collected from, not a copy of what the address serves, so it is not graded in its place. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 0.5.0.

One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.

Any signed-in account that does not publish Postagent can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
