Constellation MCP Server

What the code does

We read the source, 17 h ago · rules 3dff92dd89df

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 configPath = path.join(currentDir, this.CONFIG_FILENAME);

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

      - name: Update version from release tag
        env:
          TAG_NAME: ${{ github.event.release.tag_name }}

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.

claude mcp add constellation -- npx -y @constellationdev/mcp

{
  "mcpServers": {
    "constellation": {
      "args": [
        "-y",
        "@constellationdev/mcp"
      ],
      "command": "npx"
    }
  }
}

[mcp_servers.constellation]
command = "npx"
args = ["-y", "@constellationdev/mcp"]

{
  "mcpServers": {
    "constellation": {
      "args": [
        "-y",

This one needs environment variables set before it will start: CONSTELLATION_ACCESS_KEY (Your Constellation access key). The author declared them in the registry entry; get the values from the project itself.
