Getting Started

Quick Launch (Docker)

Run the server in Docker:

docker run -d --name litmus-mcp-server -p 8000:8000 ghcr.io/litmusautomation/litmus-mcp-server:latest

Cursor IDE Setup

Example mcp.json configuration:

{
  "mcpServers": {
    "litmus-mcp-server": {
      "url": "http://<MCP_SERVER_IP>:8000/sse",
      "headers": {
        "EDGE_URL": "https://<LITMUSEDGE_IP>",
        "EDGE_API_CLIENT_ID": "<oauth2_client_id>",
        "EDGE_API_CLIENT_SECRET": "<oauth2_client_secret>",

        "NATS_SOURCE": "<LITMUSEDGE_IP>",
        "NATS_PORT": "4222",
        "NATS_USER": "<access_token_username>",
        "NATS_PASSWORD": "<access_token_from_litmusedge>",

        "INFLUX_HOST": "<LITMUSEDGE_IP>",
        "INFLUX_PORT": "8086",
        "INFLUX_DB_NAME": "tsdata",
        "INFLUX_USERNAME": "<datahub_username>",
        "INFLUX_PASSWORD": "<datahub_password>"
      }
    }
  }
}

Header Configuration Guide:

• EDGE_URL: Litmus Edge base URL (include https://)
• EDGE_API_CLIENT_ID / EDGE_API_CLIENT_SECRET: OAuth2 credentials from Litmus Edge
• NATS_SOURCE: Litmus Edge IP (no http/https)
• NATS_USER / NATS_PASSWORD: Access token credentials from System → Access Control → Tokens
• INFLUX_HOST: Litmus Edge IP (no http/https)
• INFLUX_USERNAME / INFLUX_PASSWORD: DataHub user credentials

See the Cursor docs for more info.

Configuration Notes

* NATS Topic Tools Requirements: To use get_current_value_from_topic and get_multiple_values_from_topic, you must configure access control on Litmus Edge:

1. Navigate to: Litmus Edge → System → Access Control → Tokens
2. Create or configure an access token with appropriate permissions
3. Provide the token in your MCP client configuration headers

** InfluxDB Tools Requirements: To use get_historical_data_from_influxdb, you must allow InfluxDB port access:

1. Navigate to: Litmus Edge → System → Network → Firewall
2. Add a firewall rule to allow port 8086 on TCP
3. Ensure InfluxDB is accessible from the MCP server host
