Prometheus MCP Server (Go)
A Model Context Protocol (MCP) server for Prometheus integration. Native Go binary with built-in Kubernetes connectivity via client-go.
Installation
npx
npx -y mcp-prometheus@latest
MCP Client Configuration
Add to your MCP client configuration (VS Code, Cursor, Windsurf, etc.):
{
"mcpServers": {
"prometheus": {
"command": "npx",
"args": ["-y", "mcp-prometheus@latest"],
"env": {
"PROMETHEUS_URL": "http://localhost:9090"
}
}
}
}
VS Code
code --add-mcp '{"name":"prometheus","command":"npx","args":["-y","mcp-prometheus@latest"],"env":{"PROMETHEUS_URL":"http://localhost:9090"}}'
Kubernetes Auto-Connect
Automatically connects to Prometheus running in OpenShift/Kubernetes via the K8S API service proxy. Uses native kubeconfig/in-cluster config via client-go. No kubectl or port-forwarding required.
Default: openshift-monitoring/prometheus-operated:9090
{
"mcpServers": {
"prometheus": {
"command": "npx",
"args": ["-y", "mcp-prometheus@latest"]
}
}
}
Binary
Download from GitHub Releases or build from source:
make build
./mcp-prometheus
