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
