sealkeep MCP Server

local only

sealkeep runs on your own machine — the client starts it, so there is no endpoint to ping. 195 installs a week from npm. Last commit 9 Oct 2026.

Let AI agents use secrets without seeing them: inject into a command, redact the output.

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs a command on install [пакет] package.json:1
postinstall: node bin/postinstall.js
  const res = spawnSync(bin, args, { stdio: 'inherit' });
Builds a file path from a variable npm/build-mcpb.mjs:48
    copyFileSync(path.join(here, 'bin', f), path.join(stage, 'server', f));

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add sealkeep -- npx -y @munhq/sealkeep

    "sealkeep": {

This one needs environment variables set before it will start: SEALKEEP_CONFIG (Path of the config file (stores, aliases, guard rules). Default: the config folder of the OS, for example ~/.config/sealkeep/config.toml. With no file, sealkeep uses the OS keyring.). The author declared them in the registry entry; get the values from the project itself.

sealkeep — questions

Answers built from our own checks of this server.

Why is there no uptime for sealkeep?
sealkeep runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @munhq/sealkeep was installed 195 times last week.
How do I connect sealkeep?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @munhq/sealkeep straight from npm; nothing to host, nothing to sign up for.
How many people use sealkeep?
The npm package @munhq/sealkeep was installed 195 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is sealkeep open source?
Yes — it is published under the MIT licence, written in Rust and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
