Nothing serious here today

Today is the operative word: we check Omniseal every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

seal

seal_files

Conceal a secret file inside a cover file, returning a new sealed file without overwriting originals. File results are binary MCP resources; this connector rejects results exceeding its 140,000-character limit. Inputs require actual file bytes or reachable URLs.

verify

verify_sealed_file

Check whether an Omniseal sealed file shows signs of tampering. File results are binary MCP resources; this connector rejects results exceeding its 140,000-character limit. Inputs require actual file bytes or reachable URLs.

Omniseal — questions

Answers built from our own checks of this server.

What can Omniseal do?

It exposes 4 tools, read directly from the server on our last check. Among them: remove_hidden_file, retrieve_secret_file, seal_files, verify_sealed_file. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Omniseal working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 338 ms. The bar chart above shows every period we have measured.

How do I connect Omniseal?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Omniseal need an API key?

No. Omniseal completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Omniseal?

It answers our handshake in 338 ms on average, which is faster than 41% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Omniseal open source?

We cannot say either way: 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
