Usage

Prerequisites

Before using this MCP server, you need to generate a personal access token from your esa.io team:

1. Go to https://<TEAM_NAME>.esa.io/user/applications
2. Create a new personal access token
3. Copy the token for configuration

Configuration

You can run the server either via npx or Docker.

Using npx

Add the following configuration to your MCP client:

{
  "mcpServers": {
    "esa": {
      "command": "npx",
      "args": [
        "-y",
        "@koki-develop/esa-mcp-server@latest"
      ],
      "env": {
        "ESA_TEAM": "<your-team-name>",
        "ESA_ACCESS_TOKEN": "<your-personal-access-token>"
      }
    }
  }
}

Replace <your-team-name> and <your-personal-access-token> with your team name and personal access token.

Using Docker

If you prefer Docker, use the following configuration:

{
  "mcpServers": {
    "esa": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "ESA_TEAM",
        "-e",
        "ESA_ACCESS_TOKEN",
        "ghcr.io/koki-develop/esa-mcp-server:latest"
      ],
      "env": {
        "ESA_TEAM": "<your-team-name>",
        "ESA_ACCESS_TOKEN": "<your-personal-access-token>"
      }
    }
  }
}

Read-only Mode

To enable read-only mode that only allows read operations, add the --readonly flag.

Using npx:

{
  "mcpServers": {
    "esa": {
      "command": "npx",
      "args": [
        "-y",
        "@koki-develop/esa-mcp-server@latest",
        "--readonly"
      ],
      "env": {
        "ESA_TEAM": "<your-team-name>",
        "ESA_ACCESS_TOKEN": "<your-personal-access-token>"
      }
    }
  }
}

Using Docker:

{
  "mcpServers": {
    "esa": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "ESA_TEAM",
        "-e",
        "ESA_ACCESS_TOKEN",
        "ghcr.io/koki-develop/esa-mcp-server:latest",
        "--readonly"
      ],
      "env": {
        "ESA_TEAM": "<your-team-name>",
        "ESA_ACCESS_TOKEN": "<your-personal-access-token>"
      }
    }
  }
}
