What the code does

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.

   const child=spawn(process.execPath,[fileURLToPath(new URL(worker,import.meta.url)),this.config.configPath,id],{detached:true,stdio:'ignore',env:process.env});
Builds a file path from a variable src/bridge.ts:51
  const parent=await project(this.config,args.parent);const dest=path.join(parent,args.name);

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

This one needs environment variables set before it will start: COS_BRIDGE_CONFIG (Absolute path to the private config.json created by the CoS Codex Bridge installer.). The author declared them in the registry entry; get the values from the project itself.

CoS Codex Bridge — questions

Answers built from our own checks of this server.

Why is there no uptime for CoS Codex Bridge?
CoS Codex Bridge 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 cos-codex-bridge.
How do I connect CoS Codex Bridge?
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 cos-codex-bridge straight from npm; nothing to host, nothing to sign up for.
Is CoS Codex Bridge open source?
Yes — it is published under the MIT licence, written in TypeScript and 2 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.
