Datadog MCP Server vs Grafana MCP Server
Grafana MCP Server scores 74.5 (BB) on agent readiness against Datadog MCP Server's 56.6 (C), and leads in 5 of 7 scored categories. Datadog MCP Server leads on security & auth. Both do observability metrics.
Which one, for what
Good for Agents that triage production issues across metrics, logs, traces and monitors in a Datadog org. sentry-mcp is narrower and deeper on errors, pagerduty-mcp covers on-call.
Ahead on
- Security & auth, 76 against 65
Also in its favour
- A hosted endpoint, with nothing to install
Watch for
Tools and parameters are removed the day they're announced, with no notice period
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 53
- Schema & documentation, 81 against 60
- Payments & pricing, 60 against 20
- Maintenance & community, 95 against 68

Verdicts
Datadog MCP Server
OAuth read-only grants, mcp_read and mcp_write permissions and an organisation-level block on MCP writes. Tools and parameters are removed the day they're announced, with no notice period.
Grafana MCP Server
Every tool carries typed inputs and read-only, destructive and idempotent annotations, and --disable-write cuts the default 79 tools to 62. Writes and a general grafana_api_request tool are on by default, the default tool list is about 107 KB, and usage statistics have been sent to Grafana Labs by default since 2.0.0.
Before you call either
Datadog MCP Server
- Use https://mcp.datadoghq.com/v1/mcp. The /api/unstable/ path in older configs is no longer the documented one
- Set
toolsetsto the two or three you need, for example core plus logs, and read thetoolsetsresource first - Pass
limitandcustom_attributeson span searches, and page withcursor.start_atis gone - Expect a permission error when the org blocks MCP writes or the OAuth grant is read-only. That's the boundary working
- Budget calls. The org shares 100,000 a month and 50 per 10 seconds
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
