Amazon Managed Prometheus MCP Server
An MCP (Model Context Protocol) server that provides access to Amazon Managed Prometheus workspaces using the FastMCP SDK and uv for fast Python package management.
Features
- List Amazon Managed Prometheus workspaces
- Get workspace details and configuration
- Query metrics from Prometheus workspaces
- Execute PromQL queries
- Get workspace status and metadata
- Fast dependency management with
uv
Prerequisites
- Install uv (if not already installed):
# On macOS and Linux
curl -LsSf https://astral.sh/uv/install.sh | sh
# On Windows
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"
# Or with pip
pip install uv
- AWS Credentials: Configure AWS credentials (one of the following):
- AWS CLI:
aws configure - Environment variables:
AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_REGION - IAM roles (if running on EC2)
Installation
Quick Start with uv
# Clone or navigate to the project directory
cd prometheus-mcp-server
# Create virtual environment and install dependencies
uv sync
# Activate the virtual environment
source .venv/bin/activate # On Unix/macOS
# or
.venv\Scripts\activate # On Windows
# Run the server
uv run prometheus-mcp-server
Development Installation
# Install with development dependencies
uv sync --extra dev
# Install with test dependencies
uv sync --extra test
# Install all optional dependencies
uv sync --all-extras
Alternative Installation Methods
# Install in editable mode
uv pip install -e .
# Install from PyPI (when published)
uv pip install prometheus-mcp-server
# Install specific version
uv pip install prometheus-mcp-server==0.1.0
Usage
Running the MCP Server
# Using uv run (recommended)
uv run prometheus-mcp-server
# Or after activating virtual environment
prometheus-mcp-server
# Run with specific region
AWS_REGION=us-west-2 uv run prometheus-mcp-server
Testing the Server
# Run all tests
uv run pytest
# Run tests with coverage
uv run pytest --cov=prometheus_mcp_server
# Run integration tests
uv run python test_demo.py
# Run simple server test
uv run python src/prometheus_mcp_server/simple_server.py
Development Commands
# Format code
uv run black src/ tests/
uv run isort src/ tests/
# Lint code
uv run ruff check src/ tests/
# Type checking
uv run mypy src/
# Run all quality checks
uv run black --check src/ tests/
uv run isort --check-only src/ tests/
uv run ruff check src/ tests/
uv run mypy src/
uv run pytest
Required AWS Permissions
The server requires the following AWS permissions:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"aps:ListWorkspaces",
"aps:DescribeWorkspace",
"aps:QueryMetrics"
],
"Resource": "*"
}
]
}
list_workspaces: List all Amazon Managed Prometheus workspacesget_workspace: Get detailed information about a specific workspacequery_metrics: Execute PromQL queries against a workspaceget_workspace_status: Get the current status of a workspace
Configuration

Troubleshooting
Common Issues
- FastMCP not found:
# Install FastMCP from GitHub
uv add git+https://github.com/jlowin/fastmcp.git
- AWS Credentials Error:
# Configure AWS credentials
aws configure
# or set environment variables
export AWS_ACCESS_KEY_ID=your_key
export AWS_SECRET_ACCESS_KEY=your_secret
- Permission Denied:
- Ensure IAM user/role has required AMP permissions
- Check AWS region configuration
Debug Mode
# Enable verbose logging
LOG_LEVEL=DEBUG uv run prometheus-mcp-server
# Run with AWS debug
AWS_DEBUG=1 uv run prometheus-mcp-server
