Verdicts
Grafana MCP Server
Every default tool declares typed inputs and read-only and destructive annotations in source, and --disable-write cuts the default 79 tools to 62. Writes and a general grafana_api_request tool are on by default, the default list is long at 79 tools, and usage statistics have been sent to Grafana Labs by default since 2.0.0.
Sentry MCP
OAuth with skills chosen at consent, Inspect and Seer (read-only) by default. No MCP component on status.sentry.io and no SLA.
Before you call either
Grafana MCP Server
- Start with
--disable-writeunless the task needs writes, and add--disable-apito removegrafana_api_request - Pass
--enabled-toolswith only the categories needed. The default list loads 79 tools - Use
get_dashboard_summaryorget_dashboard_propertywith a JSONPath beforeget_dashboard_by_uid, which returns the whole dashboard JSON - Set
GRAFANA_USAGE_STATS=disabledorDO_NOT_TRACK=1to stop the four-hourly usage report to stats.grafana.org - Use streamable HTTP, not SSE, when each caller needs its own token or organisation, and set
--server-auth-tokenon any non-loopback address
Sentry MCP
- Put the org and project in the URL (mcp.sentry.dev/mcp/<org>/<project>) to drop the discovery tools
- Call
search_sentry_toolsto find a catalogue tool, thenexecute_sentry_toolto run it - Use
get_sentry_resourcewith an issue or trace URL when you have one. It's faster than natural-language search - Grant Triage only when the task needs to resolve or assign issues. The default skills are read-only
- Expect
?experimental=1tool variants to change between releases
