Grafana version compatibility

Some datasource API paths exist only in newer Grafana releases. This article explains a common error on Grafana before 9.0.

What you’ll achieve

You can confirm whether an upgrade fixes datasource-related MCP errors.

Before you begin

• Access to upgrade or validate the Grafana version for your stack.

Recognize the error

If you see an error like this when using datasource-related tools:

Copy

get datasource by uid : [GET /datasources/uid/{uid}][400] getDataSourceByUidBadRequest {"message":"id is invalid"}

you are likely on Grafana before 9.0. The /datasources/uid/{uid} API was added in Grafana 9.0; datasource operations that rely on it fail on older versions.

Resolve the issue

Upgrade Grafana to 9.0 or later. The MCP server requires Grafana 9.0 or later for full functionality.
