MCP Server

SRE Portal includes built-in Model Context Protocol (MCP) servers that let AI assistants query DNS records and alerts.

Endpoints

Several MCP servers are mounted on the same port as the web UI (8090 by default). All use Streamable HTTP transport.

Once connected to the DNS server, you can ask:

“List all available portals”
“Search for FQDNs containing api”
“Get details for api.example.com”
“Show all external-dns entries in the production portal”
“What DNS records are in the monitoring group?”

With the alerts server:

“List active alerts for the main portal”
“Show firing alerts”
“List alerts containing ‘disk’”

With the metrics server:

“Show me all SRE Portal metrics”
“What’s the current reconciliation rate?”

With the releases server:

“List today’s releases”
“Add a deployment release for v2.1.0 from CI/CD”
“Show releases for 2026-03-19”

With the image inventory server:

“List all container images in the main portal”
“Which workloads use images tagged latest?”
“Show images from ghcr.io”
“List images with semver tags”
