 ## Usage
 
 1. Create a service account in Grafana with enough permissions to use the tools you want to use,
-generate a service account token, and copy it to the clipboard for use in the configuration file.
-Follow the [Grafana documentation][service-account] for details.
-
-2. Add the server configuration to your client configuration file. For example, for Claude Desktop:
-
-```json
-{
-  "mcpServers": {
-    "grafana": {
-      "command": "uvx",
-      "args": [
-        "mcp-grafana"
-      ],
-      "env": {
-        "GRAFANA_URL": "http://localhost:3000",
-        "GRAFANA_API_KEY": "<your service account token>"

-> Note: if you see `Error: spawn uvx ENOENT` in Claude Desktop, you need to specify the full path to `uvx` (see [discussion](https://github.com/orgs/modelcontextprotocol/discussions/20))
+2. Download the latest release of `mcp-grafana` from the [releases page](https://github.com/grafana/mcp-grafana/releases) and place it in your `$PATH`.
 
-To disable a category of tools, set the environment variable `GRAFANA_TOOLS__<CATEGORY>__ENABLED` to `"false"`.
-For example, to disable the search tools, set `"GRAFANA_TOOLS__SEARCH__ENABLED": "false"`.
+   If you have a Go toolchain installed you can also build and install it from source, using the `GOBIN` environment variable
+   to specify the directory where the binary should be installed. This should also be in your `PATH`.
 
-## Development

 ### Testing
 
-TL;DR: start a Grafana instance with `docker-compose up`, run `uv run ruff check .` for lints, and `uv run pytest tests --integration` to run unit and integration tests.

 To run unit tests, run:

 More comprehensive integration tests will require a Grafana instance to be running locally on port 3000; you can start one with Docker Compose:
