Provides read-only access to Prometheus instant queries, active alerts, and target health with bounded query lengths and response sizes.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@Prometheus Safe MCPCheck the current CPU usage across all nodes."
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Prometheus Safe MCP
A focused, read-only MCP server for bounded Prometheus instant queries, active alerts, and target health. Alpha: tests use synthetic HTTP responses; compatibility with a live Prometheus release is not certified.
Install and run
Requires Python 3.11+ and uv.
uv sync --extra test
export PROMETHEUS_SAFE_URL=https://prometheus.example.invalid
uv run prometheus-safe-mcpThe process speaks MCP over stdio. It does not load .env; .env.example is documentation only. Configure the URL of a read-only, network-restricted Prometheus endpoint.

Safety
All tools use HTTP GET. Query length, HTTP duration/bytes, and returned target count are bounded. Configuration rejects URL credentials, queries, fragments, and non-HTTP schemes. Audit records contain operation categories rather than PromQL text or response bodies. This does not replace upstream authentication, authorization, or egress policy. See security design.
