| Name | Type | Credentials | License | Clients | Verdict |
|---|---|---|---|---|---|
| Datadog MCP Server Datadog | MCP server | Required | MIT | 11 | Pick it to investigate production issues from the agent using your Datadog account; OAuth keeps access within your existing RBAC. |
| Next.js DevTools MCP Vercel | MCP server | None | MIT (stated in README; GitHub detects no LICENSE file) | 9 | Pick it to let the agent read live errors, routes and logs from a running Next.js 16+ dev server; it needs `npm run dev` running. |
| Chrome DevTools MCP Chrome DevTools (Google) | MCP server | None | Apache-2.0 | 3 | Pick it for performance traces, network and console debugging; it exposes browser content to the client. |
| Elasticsearch MCP Server (deprecated) Elastic | MCP server | Required | Apache-2.0 | 3 | Avoid for new setups: the official README marks it deprecated; use it only on existing installs. |
| Grafana MCP Grafana Labs | MCP server | Required | Apache-2.0 | 3 | Pick it to query dashboards, Prometheus and Loki from the agent; needs a Grafana service account token. |
| Sentry MCP Sentry | MCP server | Required | NOASSERTION | 2 | Pick it to debug production errors from Sentry inside the agent; needs Sentry OAuth or a user token. |
| Cloudflare MCP servers Cloudflare | MCP server | Required | Apache-2.0 | 1 | Pick it for Workers, observability and Cloudflare docs; each remote server uses its own OAuth scopes. |
