How do I use query-layer?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@query-layer ping the query layer to check if it's responsive" 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.

Python

MCP Server for Query Layer API

An MCP (Model Context Protocol) server that exposes a metrics query-layer API to AI assistants. Built with the official Python MCP SDK v2.

Quick Start

# Prerequisites: Python 3.10+, uv
uv sync
uv run mcp dev src/server.py

Open the MCP Inspector at the URL printed to the console. You'll see the ping tool available.

Related MCP server: prometheus-mcp

Cursor Integration

The .cursor/mcp.json file is pre-configured. Restart Cursor and the query-layer MCP server will be available to the AI assistant.

Local Tracing with Phoenix (Optional)

# Terminal 1: start Phoenix
uv run phoenix serve

# Terminal 2: run the server pointing at Phoenix
export PHOENIX_COLLECTOR_ENDPOINT=http://localhost:6006
uv run mcp dev src/server.py

View traces at http://localhost:6006 — Phoenix natively renders MCP tool calls, prompts, and GenAI spans.
