Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "dev-mightys-cairn": {
      "command": "npx",
      "args": [
        "-y",
        "@bborota/cairn-mcp"
      ],
      "env": {
        "CAIRN_KEY_PATH": "<CAIRN_KEY_PATH>",

      }
    }
  }
}
Run commandnpx -y @bborota/cairn-mcp
Environment variables to set
CAIRN_KEY_PATHSecretPath of the local Ed25519 credentials file the client creates on first run (default ~/.cairn/credentials.json, mode 0600). The key never leaves the machine.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
