Plugins for Claude Code and Cursor that connect an agent to the Agent Tools MCP servers by OpenKrill. Each plugin is one tool family: a skill per server that says when to use it, plus the remote MCP config for those servers. 9 plugins bundle 54 public MCP servers. None needs an API key, a sign-up or a local process.

claude plugin marketplace add nguyenhieuec/agent-tools-plugins
claude plugin install dev-security@openkrill
Start a new session and ask: "Is lodash 4.17.15 vulnerable, and which version fixes it?"
Install any other family the same way.
Inside a session, /plugin marketplace add nguyenhieuec/agent-tools-plugins and /plugin do the same.
Cursor reads the same plugins through .cursor-plugin/marketplace.json.
A team admin can import this repository under Dashboard, Plugins & MCPs, Team Marketplaces, Import from Repo, and members install from Customize.
To try one family alone, clone this repository and copy plugins/<family> to ~/.cursor/plugins/local/<family>, then run Developer: Reload Window.
The Cursor CLI loads a family directly: cursor-agent --plugin-dir plugins/<family>.
Each family also has a plain mcp.json you can merge into ~/.cursor/mcp.json without the skills.
Add the API server alone and ask it: its index_tools tool searches every Agent Tools server by task in plain words and answers with the tool name and the MCP address to add.
claude mcp add --transport http openkrill https://api.openkrill.app/mcp
The plugin servers do not list index_tools: each one describes only its own tools.
The gateway at https://api.openkrill.app/gateway/mcp lists the tools of every server, named <server>__<tool> (for example packages__check_package), and runs each call on the owning server with its usual per-network limits.
The full list has every tool of every server, about 200 KB, so a client that loads every tool into the model should pick a family with ?servers=:
claude mcp add --transport http openkrill-dev-security "https://api.openkrill.app/gateway/mcp?servers=dev-security"
?servers= takes a family name or server names, comma-separated.
The same tools work in Zapier without code: join the OpenKrill Tools integration with this invite link. It is early and private until Zapier reviews it; every action is one gateway call and needs no key.

There are no accounts. Most servers keep only daily call counts and a short cache of public data. Some keep what their tools say they keep: Store Price Tracker keeps public store snapshots, Taste Profile and Outreach Desk keep a profile under a key only you hold, and Transcript Kit keeps a transcript for 24 hours. What each server receives, keeps and for how long: https://tools.openkrill.app/privacy#per-server. Terms: https://tools.openkrill.app/terms.

Copy the http config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.
