¿Este servidor envía mis datos a algún lado?

No. No abre ninguna conexión de red ni hace solicitudes salientes de ningún tipo. Todo se calcula localmente en el proceso que corre en su máquina. El código fuente es un único archivo legible con licencia MIT, así que usted puede verificar esta afirmación en lugar de confiar en nuestra palabra.

¿Es gratis y necesito una API key?

Es gratuito y de código abierto, y no necesita API key ni cuenta. Ninguna de las seis herramientas llama a un modelo de IA: son cálculo local corriente, que es exactamente la razón por la que pueden funcionar sin credenciales y sin enviar nada a ningún lado.

Servidor MCP de OmniDeck

Caja de Herramientas IA

A free, open-source MCP server that gives Claude, Cursor or any AI agent six tools that run entirely on your own machine. It makes no network calls of any kind, so the secrets and documents you hand it never leave your computer.

Install

Requires Node.js 18 or newer. For Claude Code, run this in your terminal:

claude mcp add omnideck -- npx -y omnideck-mcp

For Claude Desktop, add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "omnideck": {
      "command": "npx",
      "args": ["-y", "omnideck-mcp"]
    }
  }
}

The six tools

Redact sensitive data, masks emails, API keys, credit cards, IBANs, IP addresses and phone numbers before text reaches an external API.
Decode a JWT, reads a token's header, payload and expiry locally, so a live credential never gets pasted into a website.
Estimate LLM cost, compares what one request would cost across nine GPT, Claude and Gemini models, cheapest first.
Split for context, breaks a long document into chunks that fit a context window, cutting on paragraph boundaries.
Check output fidelity, flags names, numbers and dates that appear in an AI summary but not in the source it came from.
Hash text, computes MD5, SHA-1, SHA-256 or SHA-512 digests locally, for passwords and other private values.

How to use the OmniDeck MCP server

Install it with one of the commands above, no account, no API key, no configuration file to write by hand.
Restart your AI client so it picks up the new server.
Ask your assistant to use a tool in plain language, for example, "scrub the secrets out of this log before we look at it."

What is MCP, and why does this server exist?

MCP (Model Context Protocol) is an open standard that lets an AI assistant call external tools instead of guessing at answers on its own. Most MCP servers connect an assistant to a remote service, which means your data travels to somebody else's infrastructure to be processed. This one is deliberately the opposite: every tool here is pure local computation inside your own machine. It exists because a specific group of everyday tasks, decoding a token, hashing a password, scrubbing a log file, are normally solved by pasting the sensitive value into a random website, which is precisely the thing a careful person should not do.

Does this server send my data anywhere?

No. It opens no network connections and makes no outbound requests of any kind. Everything it does is computed locally in the process running on your machine. The source is a single readable file under an MIT license, so you can verify this claim yourself rather than taking our word for it.

Is it free, and do I need an API key?

It is free and open source, and it needs no API key or account. None of the six tools call an AI model, they are ordinary local computation, which is exactly why they can run without credentials and without sending anything anywhere.
