Plan: Tag Grafana Dashboards with app_code Tags

Phase 0: Documentation & API Confirmation

Findings:

• mcp__grafana__update_dashboard supports patching $.tags via JSONPath
• Append: {"op": "add", "path": "$.tags/- ", "value": "app_code=fxa"}
• Replace: {"op": "replace", "path": "$.tags", "value": ["app_code=fxa", ...]}
• Folders cannot be tagged — only dashboards
• Must read existing tags first, then replace with merged array to avoid clobbering

Anti-patterns:

• Don't blindly append if $.tags is null/missing
• No filter expressions in JSONPath — only numeric indices
• Don't attempt to tag folders

Phase 1: List Dashboards per Folder and Read Existing Tags

For each folder in the mapping, search for all dashboards, then read current tags via get_dashboard_property(uid, "$.tags").

33 folder-to-app_code mappings across 26 tenants:

Confidence	Count	App Codes
High	25 folders	0din, amo, autograph, autopush, balrog, bugbug, bugzilla, classify-client, cinder, common-voice (x2), crlite, ctms, dap, fakespot, fxa, merino, monitor, pontoon, relay, remote-settings, sumo, sync (x2), taskcluster, vpn
Medium	5 folders	ads, basket, bedrock, vpn (Guardian), socorro

Phase 2: Apply Tags (High Confidence Folders)

For each dashboard in high-confidence folders:

1. Read existing tags
2. Skip if app_code=<tenant> already present
3. Build merged tag array: existing + ["app_code=<tenant>"]
4. Apply via update_dashboard replace operation

Process in order of 90-day activity:

1. fxa (743 views, 25 dashboards)
2. merino (429 views, 5 dashboards)
3. taskcluster (294 views, 8 dashboards)
4. sync (225 views, 15 dashboards, 2 folders)
5. bugzilla (178 views)
6. autopush, autograph, relay, monitor
7. Remaining high-confidence folders

Verification: Search by tag app_code=<tenant> after each folder.

Phase 3: Apply Tags (Medium Confidence Folders)

Same process for:

• ads-engineering → app_code=ads
• Basket → app_code=basket
• Bedrock / www.mozilla.org → app_code=bedrock
• Guardian → app_code=vpn
• crash-ingestion → app_code=socorro

Extra caution: Shared folders (svcops) may contain multi-tenant dashboards — only tag where slug/title clearly matches.

Phase 4: Tag Orphan Dashboards

Dashboards in shared folders matched to tenants by the 90-day activity cross-reference:

Dashboard	UID	Tag
AMO	CsSDyxTZ1	app_code=amo
Autograph	gohbKM0WZ	app_code=autograph
Bouncer - v2	eesc80sgxn30ge	app_code=bouncer

Phase 5: Verification & Report

1. Search Grafana for app_code=<tenant> per tenant
2. Compare counts against cross-reference
3. Update the Confluence report with tagging results
