API and MCP

The marketplace is readable by software and AI, without an account.

JSON API

GET https://marketplace.kroy.cc/api/v1/servers

Parameter	Meaning
`q`	Search words (names, descriptions, tags, tool names)
`category`	`productivity`, `development`, `data`, `finance`, `crm`, `communication`, `documents`, `search`, `design`, `operations`, `security` or `other`
`limit`	1–100, default 30
`cursor`	from `metadata.nextCursor` of the previous page

GET https://marketplace.kroy.cc/api/v1/servers/{id} returns one server.

Each server follows the shape of the official MCP Registry's server.json (name, description, version, repository, remotes, packages), plus Kroy's own details under _meta["cc.kroy.marketplace"]:

{
  "id": "acme-weather",
  "name": "Acme Weather",
  "description": "Current conditions and forecasts for any UK postcode.",
  "version": "1.2.0",
  "remotes": [{ "type": "streamable-http", "url": "https://mcp.acme.com/mcp" }],
  "_meta": {
    "cc.kroy.marketplace": {
      "url": "https://marketplace.kroy.cc/servers/acme-weather",
      "publisher": "acme",
      "reviewed": true,
      "checks": { "ok": true, "checkedAt": "2026-09-25T12:00:00Z" },
      "ratings": { "works": 14, "doesNotWork": 1 },
      "dataHandling": "Receives the postcode. Stores nothing…",
      "tools": [{ "name": "get_forecast", "description": "…", "readOnly": true, "destructive": false }],
      "toolsSource": "server"
    }
  }
}

toolsSource is server when Kroy read the tools from the server, and publisher when they were declared.

The API is rate-limited to 120 requests a minute per address. Responses allow cross-origin use and are cached for a minute.

MCP server

Add https://marketplace.kroy.cc/mcp to any MCP client (Streamable HTTP, no sign-in). It offers two read-only tools:

search_servers (query, optional category, limit): finds published servers.
get_server (id): one listing in full.

Claude Code:

claude mcp add --transport http kroy-marketplace https://marketplace.kroy.cc/mcp
