What the code does

We read the source, 20 h ago · rules 3dff92dd89df

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.

Builds a file path from a variable src/tools/preCommit.ts:30
        const fullPath = path.join(scanPath, file);
Reads files and sends them to the network src/client.ts:60
        entries = fs.readdirSync(dir, { withFileTypes: true });

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 arcwall-security -- npx -y @arcwall/mcp-server
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "arcwall-security": {
      "args": [
        "-y",
        "@arcwall/mcp-server"
      ],
      "command": "npx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.arcwall-security]
command = "npx"
args = ["-y", "@arcwall/mcp-server"]
.cursor/mcp.json
{
  "mcpServers": {
    "arcwall-security": {
      "args": [
        "-y",
        "@arcwall/mcp-server"
      ],
      "command": "npx"
    }
  }
}
.vscode/mcp.json
{
  "mcpServers": {
    "arcwall-security": {
      "args": [
        "-y",
        "@arcwall/mcp-server"
      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: ARCWALL_API_KEY (Your Arcwall API key from arcwall.io/app.html). The author declared them in the registry entry; get the values from the project itself.

Arcwall Security — questions

Answers built from our own checks of this server.

Why is there no uptime for Arcwall Security?
Arcwall Security 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 @arcwall/mcp-server was installed 26 times last week.
How do I connect Arcwall Security?
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 @arcwall/mcp-server straight from npm; nothing to host, nothing to sign up for.
How many people use Arcwall Security?
The npm package @arcwall/mcp-server was installed 26 times in the last week. Week over week that is +17%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Arcwall Security open source?
We cannot say either way: written in TypeScript and 1 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
