A collection of free online tools that an agent can call without creating an account or providing an access key. It covers everyday tasks such as converting files, making QR codes, storing temporary data, and searching by meaning.

Use it to work with time, hashes, encoded data, JSON, CSV, images, PDFs, QR codes, temporary storage, webhook requests, queues, and semantic search. A webhook is a URL that receives an event from another service; semantic search finds related meaning rather than only matching exact words.

It removes the need to build or connect separate small services for common utility tasks. It can also handle temporary coordination tasks such as queues, webhooks, and leases.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

Security

Grade A, and why

aisense scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it installs

The manifest is a name and a version. 1 skill, 1 MCP server travel with it, and installing the plugin installs all of them — 87 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
