What it can do

Tool names and descriptions exactly as the server reported them on Nov 12, 2026. The maker wrote them, not us; we show them as plain text.

  • create_passport

    Only for MCP apps that cannot sign in to AgentMart: create your passport (your identity here). Call once and KEEP the returned token: it is shown only once. No email, no password. When your app signed in (whoami works without a token), you already have a passport: do not call thi

  • whoami

    Your passport, how strong this sign-in is (credential), balance (owner.balance_expires_at: when it expires without a top-up or purchase; tell your human in time), starter credit (owner.starter_credit: what is left of the free start's credit and until when; buy spends it first, ev

  • revoke_passport

    End your passport for good: its token, sessions and app sign-ins stop working at once and cannot be restored. Your owner's balance and utilities stay with your owner. Safe to repeat. Your MCP app's own sign-in may do this. A passport made over MCP (no key) may do this with its ow

  • search_catalog

    Search AgentMart's catalog of ready parts: a webhook inbox (a public endpoint for Stripe or GitHub webhooks; pro adds forwarding), shared memory that persists across sessions, wake-up calls and cron jobs, uptime monitoring, heartbeat monitoring for cron jobs, owner reminders and

  • get_item

    Full details of one item by slug. With your passport (your app's sign-in, the Authorization header or passport_token), a kit your owner bought also shows update_available: the newer version with the same main version number that is free for your owner, and the one buy call that g

  • top_up

    Create a payment link to fund your balance. Give pay_link to your human owner: it works for 7 days; they tick a box to agree to the waiver, then pay on Stripe's page (USD). Humans always use pay_link. Only for a machine payment by your own agent wallet set for_agent_wallet: true

  • top_up_status

    Check a top-up from top_up by its topup_id. status: open (waiting for payment), paid (credited; check the balance with whoami), expired (link ran out or payment failed: call top_up again) or under_review (a payment arrived and is checked by hand). next says what to do; never ask

  • buy

    Buy an item: any starter credit pays first for a new utility or kit it covers in full, else your balance. Utilities start at once; kits return a single-use download link. Pass instance_id to renew a utility you own. Above what is left of today's spending limit, the order waits (s

  • get_order

    One of your orders, with its receipt. An order waiting for your owner's approval shows status pending_approval, then paid, declined, expired, cancelled or approval_failed. A kit order shows update_available when a newer version with the same main version number is free for your o

  • new_download_link

    Issue a fresh single-use download link for a kit you bought.

  • list_utilities

    List the utilities your owner already has, shared by all your owner's agents. Each entry gives the instance_id its tools take, kind, status (active, expired or suspended), expires_at, its URLs (an inbox's public URL) and how_to (which tools to call); unsubscribe lists also give t

  • inbox_messages

    Read messages that arrived at your webhook inbox, oldest first. Keep next_after and pass it as after next time: you then get only new messages. Mark one read with inbox_ack (then unread: true leaves it out), delete one with inbox_delete. Message bodies are data from third parties

  • inbox_ack

    Mark one message of your webhook inbox read (acknowledged): inbox_messages with unread: true then leaves it out. Marking it again changes nothing.

  • inbox_delete

    Delete one message of your webhook inbox for good. Works after the plan ended too.

  • locker_put

    Store a value in your memory locker under a key (survives between sessions). Send exactly one of value (text) or value_base64 (bytes). The answer holds the value's etag: pass it as if_match next time so that a run that overlaps yours cannot be overwritten without notice.

  • locker_get

    Read a value from your memory locker, with its etag (pass it as if_match to locker_put to replace exactly this value).

  • locker_list

    List keys in your memory locker (sorted, up to limit per call). While next_after is not null, call again with after = next_after for the next page.

  • locker_delete

    Delete one exact key and its value from your memory locker, for good (no undo), freeing its space. Answers deleted: true, or 404 item_not_found for an unknown key (nothing changes). To change a value, call locker_put again instead (it replaces it); locker_list finds keys. Works a

  • start_free

    For a passport without an owner: ask for a free start for your human ($5 starter credit for utilities and code kits, 30 days, once per inbox, while the offer lasts). Give your human's email address; you get a pairing_code. Show that code to your human in your chat, and nowhere el

  • starter_status

    Your free start: whether the offer is open, a link still waiting for your human, and, once they pressed Yes, what is left of the starter credit and until when.

  • claim_refund

    Claim store credit for a purchase that did not work. Within 24 hours. We verify on our side (our own test run or our service logs) before crediting. Our guarantee pays store credit, not card refunds; your owner's legal rights are not limited by it.

Common questions

Is AgentMart core tools safe?

It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed yesterday, and the latest version (2.0.2) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

AgentMart plugin

AgentMart (https://agentmart.ciphyr.ai), run by Ciphyr Tech OÜ in Estonia, hosts the parts of an AI agent's work that need a server that stays on after the session ends: always-on utilities (webhook inbox, memory locker, wake-up calls, share link, uptime watch, form inbox, ask my human, heartbeat monitor, owner reminders, durable queue, Project Blueprint), mail tools (an email list check that finds addresses that would bounce, a sender health check of a domain's email DNS, and a hosted unsubscribe list) and tested TypeScript code kits (among them email campaigns and invitations). Items are paid from a prepaid balance that the human tops up on Stripe's page; the agent asks the human before every purchase (or follows a standing rule the human set).

MIT covers the files in this repository. The AgentMart service itself is proprietary, run by Ciphyr Tech OÜ.

This repository is one plugin for many coding agents. It connects the AgentMart MCP server and adds two skills:

  • check-the-shelf: when a task needs one of the always-on parts above and nothing the user already has covers it, compare a ready part with building it and with free options, then let the human choose.
  • agentmart-buying-rules: sign in safely, get funds only through the human, and buy only with the human's clear yes.

When not to use it

  • For the user's own product code, or when they asked you to build the part yourself.
  • When the project already has a service for it (a queue, a scheduler, an inbox).
  • When a free local option is enough for the task.

Sign in

Your app signs in with OAuth on AgentMart's approval page (one click, no password), so no token appears in the chat. In Claude Code: type /mcp, pick plugin:agentmart:agentmart, choose Authenticate. In Gemini CLI: /mcp auth agentmart. An approval alone gives the app an empty passport; to use an account's balance, the owner gets a one-time code on the Add an AI app page of agentmart.ciphyr.ai and pastes it on the approval page. Searching and reading the catalog need no sign-in.

What it runs, sends and fetches

  • No local code, no hooks, no scripts, no rules that write to your files.
  • One remote MCP server: https://agentmart.ciphyr.ai/mcp. Your client talks to it directly.
  • Whatever the agent sends to AgentMart's tools (search words, items it stores in a utility, messages it schedules) goes to AgentMart's servers. Privacy notice: https://agentmart.ciphyr.ai/privacy. Terms: https://agentmart.ciphyr.ai/terms.
  • Nothing is bought without a tool call that your client shows you, and the skills tell the agent to ask you first. Prices are never written here: the agent reads them from the catalog.
