feat(coroot): give agents read-only MCP access with a Viewer service account - #5881
The maintainer wants the agents to use the platform's own services through the agentic-engineering plugin. Coroot has a built-in MCP endpoint, but agents can't reach it today: the whole Coroot host sits behind oauth2-proxy's browser SSO, which an agent can't complete.
What
Viewer service account. The Coroot resource gets an agentic-engineer service account with the Viewer role. The operator generates its API key into the coroot-mcp-agent Secret when that Secret is missing, so no key is committed. A Viewer can read topology, alerts, incidents, traces, metrics and logs, but cannot resolve alerts.
Direct /mcp route. The Coroot HTTPRoute sends exactly /mcp from the Gateway to the coroot-coroot Service. Every other path still goes through oauth2-proxy.
Gateway policy. A new CiliumNetworkPolicy, allow-gateway-to-coroot-mcp, admits Gateway traffic on port 8080 to the Coroot app pod only, not to the rest of observability.
Why bypassing the proxy for /mcp is safe
Coroot runs with authAnonymousRole: Admin because oauth2-proxy guards the UI. The MCP endpoint never uses that role. Coroot's handler (api/mcp.go, v1.28.1) answers 401 unless the request carries a bearer token, either an OAuth token or a service-account API key. Every tool call is then checked against that identity's role. So the direct route exposes only what a valid key's role allows.
Coroot's OAuth discovery and consent pages stay behind SSO, so only a signed-in person can obtain an OAuth token.
Validation
ksail workload validate and ksail --config ksail.prod.yaml workload validate pass: 772 files, including controllers/coroot and infrastructure/coroot.
The pinned naming gate passes.
Every scripts/tests/test-coroot-*.sh, route and network-policy test passes, except test-coroot-dns-resolution.sh, which needs Docker locally.
Operator chart 0.10.6 ships coroot-operator 1.10.6, whose serviceAccounts[].apiKeys[].keySecret creates the Secret. Coroot v1.28.1 reads auth.serviceAccounts and accepts API keys on /mcp.
After deployment, I'll verify that /mcp answers 401 without a key, that it lists tools with the Viewer key, and that resolve_alerts is refused.
…account
Coroot's /mcp endpoint authenticates every request itself: a bearer OAuth
token or a service-account API key, never the anonymous role the UI uses
behind oauth2-proxy, and every tool call is checked against that
identity's role. Agents cannot complete browser SSO, so they could not
reach it.
Add an agentic-engineer service account with the Viewer role, whose API
key the operator generates into the coroot-mcp-agent Secret, so the key
is never committed. A Viewer can read topology, alerts, incidents,
traces, metrics and logs but cannot resolve alerts. Route exactly /mcp
from the Gateway to Coroot, keeping every other path behind oauth2-proxy,
and admit Gateway traffic to the Coroot app pod only.

Walkthrough
The changes add a Coroot Viewer account for MCP access. They route exact /mcp requests to the Coroot service on port 8080 and add a Cilium network policy that permits ingress-entity traffic to that port. Other paths continue to use the existing oauth2-proxy backend.
Possibly related issues
Issue 1881 — The /mcp route overlaps with its objective of routing traffic directly to Coroot, but this change does not implement native ExternalAuth for other traffic.
Merge Risk: Low · previous review 51e3e
Agent MCP access could keep using a stale key after the Secret is deleted and recreated or rotated externally, until Coroot restarts. Adding the Secret to the reload annotation is a small fix. Otherwise the change is mergeable.

- Around line 92-93: Update the existing secret reload annotation in the Coroot
configuration to include the coroot-mcp-agent Secret alongside the current
entries, so changes to the Secret referenced by keySecret trigger a Coroot
restart.

The operator hands the coroot-mcp-agent key to Coroot through an env var,
which is read only at start, so a rotated key would stay unusable until a
restart. Add the Secret to the existing Reloader annotation.

Every other path still goes through oauth2-proxy.allow-gateway-to-coroot-mcp, admits Gateway traffic on port 8080 to the Coroot app pod only, not to the rest ofobservability.Why bypassing the proxy for

Coroot's handler (api/mcp.go, v1.28.1) answers401unless the request carries a bearer token, either an OAuth token or a service-account API key. Every tool call is then checked against that identity's role.
