Common questions

Is Agent Tools API safe?

It passed 0 of 1 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 –, and the latest version (0.1.1) reached the registry 16 days ago.

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 in developer mode.

What can I use instead?

Agent Tools plugins

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.

Install in Claude Code

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.

Plugin	What it covers	Install
`dev-security`	Package health, CVE triage, software end-of-life and licence facts, DESIGN.md lint and diff, and AI coding agent news.	`claude plugin install dev-security@openkrill`
`web-email`	Audit a site's SEO and AI crawler access, read a web page as clean Markdown, check a domain's mail delivery, see if a name's domain is free, and report email engagement.	`claude plugin install web-email@openkrill`
`commerce`	Store price tracking, catalog and feed checks, HS codes, duty and landed cost, US product-safety certificates, and competitor ad angles.	`claude plugin install commerce@openkrill`
`office`	Business days and holidays, US tax figures, EU VAT and company registries, document files, ready-to-send links, weekly lane plans and an AI-native team scorecard.	`claude plugin install office@openkrill`
`sales-hiring`	Buyer signals, an inbound pitch scoreboard, open jobs at named companies, remote jobs by country, and a hire-or-automate split.	`claude plugin install sales-hiring@openkrill`
`research`	Find papers, check references and DOIs, read US federal regulations, compare country statistics, and make a school digest.	`claude plugin install research@openkrill`
`markets`	Technical indicators over a price series, candlestick charts for a ticker, liquidity pool fee and volume checks, and token red-flag screens.	`claude plugin install markets@openkrill`
`consumer`	US recalls, car reports by VIN, food facts by barcode, and travel advice with live airport status.	`claude plugin install consumer@openkrill`
`content-media`	Trending topics and post ideas, post and video script drafts, AI-writing checks, transcripts, free video, Live Photos, design taste, public views and likes of posts, plus YouTube transcripts, app reviews and X posts.	`claude plugin install content-media@openkrill`

Install in Cursor

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/ to ~/.cursor/plugins/local/ , then run Developer: Reload Window. The Cursor CLI loads a family directly: cursor-agent --plugin-dir plugins/ .

Each family also has a plain mcp.json you can merge into ~/.cursor/mcp.json without the skills.

Not sure which plugin?

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.

Every tool on one server

The gateway at https://api.openkrill.app/gateway/mcp lists the tools of every server, named __ (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.

Privacy and support

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.
