## Which one, for what

### Datadog MCP Server (C)

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:
- Reliability, 53 against 48
- Security & auth, 76 against 65

Watch for: Tools and parameters are removed the day they're announced, with no notice period

### Rootly MCP Server (C)

Good for: Incident and on-call agents in teams that already run Rootly.

Ahead on:
- Schema & documentation, 78 against 60
- Maintenance & community, 81 against 68
- Transparency & trust, 80 against 67

Also in its favour:
- Open source

Watch for: Hosted connections expose write tools by default, and the docs describe the read-only switch only for servers the owner runs

## 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.

**Rootly MCP Server.** The server is open source under Apache-2.0, ships a dated release about every two weeks, and has a slim profile and a Code Mode endpoint that cut the 218-tool list. Hosted connections expose write tools by default, and the 2.3.21 changelog records telemetry changes that broke tool calls for clients with cached schemas in late September 2026.

## Before you call either

### Datadog MCP Server

1. Use https://mcp.datadoghq.com/v1/mcp. The /api/unstable/ path in older configs is no longer the documented one
2. Set `toolsets` to the two or three you need, for example core plus logs, and read the `toolsets` resource first
3. Pass `limit` and `custom_attributes` on span searches, and page with `cursor`. `start_at` is gone
4. Expect a permission error when the org blocks MCP writes or the OAuth grant is read-only. That's the boundary working
5. Budget calls. The org shares 100,000 a month and 50 per 10 seconds

### Rootly MCP Server

1. Connect to `https://mcp.rootly.com/mcp-codemode` or add `?tool_profile=slim` to `/mcp`. The default endpoint loads about 218 tool definitions
2. Connect Code Mode in place of the classic endpoint, not beside it. The docs say models skip `execute` when both are present
3. Use a Global API key for `get_oncall_handoff_summary` and `get_oncall_shift_metrics`. Team and personal keys return partial results
4. Refetch the tool list after a server release. Curated tools reject undeclared arguments, which failed calls from cached schemas in September 2026
5. Treat a 404 from a generated tool as a possible plan limit or missing parent record, and read the hint in the response
