AgentMart

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).

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.

Install

Tested by us: Claude Code. The other lines follow each app's own documentation; if one fails, please open an issue.

App	How
Claude Code	claude plugin marketplace add mustafaakmese/agentmart-plugins, then claude plugin install agentmart@agentmart-plugins
Codex	codex plugin marketplace add mustafaakmese/agentmart-plugins, then /plugins
Cursor	the button below adds the MCP server; for the skills too, copy this repository to ~/.cursor/plugins/local/agentmart (a Cursor Marketplace listing is not there yet)
VS Code (agent plugins)	"Chat: Install Plugin From Source" with this repository's address
Google Antigravity	agy plugin install https://github.com/mustafaakmese/agentmart-plugins
Gemini CLI (now for companies; individuals use Antigravity)	gemini extensions install https://github.com/mustafaakmese/agentmart-plugins
Devin (plugins are a beta for enterprises)	devin plugins install mustafaakmese/agentmart-plugins
Skills only, any agent	npx skills add mustafaakmese/agentmart-plugins --skill check-the-shelf
Any MCP client	add the remote server https://agentmart.ciphyr.ai/mcp (streamable HTTP, OAuth)

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.
