Feature Request: True Simultaneous Multi-Organization Support

[shikiroot]

The README file mentions multi-organization support. However, the current implementation only allows specifying a single target organization at a time. This is more of an "organization-selectable" feature rather than true, simultaneous "multi-organization" support. And for teams that manage multiple Grafana organizations, the only workaround is to run and manage a separate instance of mcp-grafana for each organization.

The configuration could look something like this:

{
  "mcpServers": {
    "grafana": {
      "command": "mcp-grafana",
      "organizations": [
        {
          "name": "org1",
          "env": {
            "GRAFANA_URL": "",
            "GRAFANA_SERVICE_ACCOUNT_TOKEN": "token_for_org1",
            "GRAFANA_ORG_ID": "1"
          }
        },
        {
          "name": "org2",
          "env": {
            "GRAFANA_URL": "",
            "GRAFANA_SERVICE_ACCOUNT_TOKEN": "token_for_org2",
            "GRAFANA_ORG_ID": "2"
          }
        },
        {
          "name": "org3",
          "env": {
            "GRAFANA_URL": "",
            "GRAFANA_SERVICE_ACCOUNT_TOKEN": "token_for_org3",
            "GRAFANA_ORG_ID": "3"
          }
        }
      ]
    }
  }
}

A key part of this feature would be the ability to specify a Service Account Token for each configured organization.
