## Which one, for what

### Grafana MCP Server (BB)

Good for: Teams on Grafana, self-managed or Cloud, that want an agent to read dashboards and query Prometheus, Loki, Tempo and Pyroscope, and to work with alert rules, incidents and OnCall.

Ahead on:
- Reliability, 91 against 46
- Payments & pricing, 60 against 40
- Maintenance & community, 95 against 90

Also in its favour:
- Open source

Watch for: The default set is 79 tools, and 119 with every category on, counted from the registration code in source

### Sentry MCP (BB)

Good for: Coding agents that triage and fix production errors from Sentry. datadog-mcp covers wider observability data, pagerduty-mcp on-call and incidents.

Ahead on:
- Schema & documentation, 87 against 81
- Agent ergonomics, 85 against 74
- Security & auth, 75 against 65

Also in its favour:
- A hosted endpoint, with nothing to install
- No incidents deducted, where Grafana MCP Server loses 3 points for them

Watch for: No MCP component on status.sentry.io and no SLA

## 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

1. Start with `--disable-write` unless the task needs writes, and add `--disable-api` to remove `grafana_api_request`
2. Pass `--enabled-tools` with only the categories needed. The default list loads 79 tools
3. Use `get_dashboard_summary` or `get_dashboard_property` with a JSONPath before `get_dashboard_by_uid`, which returns the whole dashboard JSON
4. Set `GRAFANA_USAGE_STATS=disabled` or `DO_NOT_TRACK=1` to stop the four-hourly usage report to stats.grafana.org
5. Use streamable HTTP, not SSE, when each caller needs its own token or organisation, and set `--server-auth-token` on any non-loopback address

### Sentry MCP

1. Put the org and project in the URL (mcp.sentry.dev/mcp/<org>/<project>) to drop the discovery tools
2. Call `search_sentry_tools` to find a catalogue tool, then `execute_sentry_tool` to run it
3. Use `get_sentry_resource` with an issue or trace URL when you have one. It's faster than natural-language search
4. Grant Triage only when the task needs to resolve or assign issues. The default skills are read-only
5. Expect `?experimental=1` tool variants to change between releases
