Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Schema & documentation Rootly MCP Server +27

New Relic MCP Server 51

Tool input schemas are only visible through an authenticated session; the tool reference names 40 tools with one-line descriptions, so partial credit for a contract that exists but isn't public (10). docs.newrelic.com publishes llms.txt, updated 3 November 2026, and a Markdown twin of every page (10). Each tool's line says what it does, tags say which group it belongs to, and the reference says which tools need OAuth and which are preview; nothing says when not to use a tool (12). No parameters, types or enums are published; the setup examples show only the include-tags header (4). Example natural-language queries per group, a troubleshooting page for OAuth, API key, permission and connection errors, and no error code list (7). A dated what's-new feed and a 0.1.0 registry version, but no MCP changelog or server version in the docs (8). 10 + 10 + 12 + 4 + 7 + 8 = 51.

Rootly MCP Server 78

Read from the source at v2.3.21. Curated tools declare typed pydantic inputs and the rest are generated from Rootly's OpenAPI 3.0.1 description, 565 operations in the bundled copy, which the API docs also link for download (25). rootly.com/llms.txt and Markdown twins of the docs pages (10). Curated tools such as list_incidents say when to use them and when to prefer search_incidents. Generated tools carry the API's short summaries, for example "List alerts" (11). Sort orders use enums and generated tools keep the API's include enums, but severity, status and ID lists are free strings, with IDs passed comma-separated (9). The README and docs give worked calls for five tools and a troubleshooting section. The error types the server returns aren't documented (8). Semantic versioning with a dated Keep a Changelog file. The docs page still names two tools in camelCase and links the old Rootly-AI-Labs repository (15).

Agent ergonomics Rootly MCP Server +18

New Relic MCP Server 59

40 tools in the default list, above the 30-tool line (5), with the include-tags header to load only named groups (add 10, so 15). Time windows on most tools, convert_time_period_to_epoch_ms, filters on incidents, errors and logs, and NRQL's own LIMIT and FACET; no documented page size (14). The troubleshooting page covers setup errors with fixes, and the docs say nothing about tool-level error bodies (8). Every tool is a read (query, list, fetch, analyse) and the gap tool reads files the client sends, so a retry is safe; no readOnlyHint or destructiveHint was confirmed because tools/list wasn't read (12). Natural-language prompts need no parameters from the user, and the API behind the server has official NerdGraph clients; nothing agent-specific beyond skills (10). 15 + 14 + 8 + 12 + 10 = 59.

Rootly MCP Server 77

The default endpoint lists about 218 tools per the README, which the checklist scores at 5. A slim profile (77 names in the source, about 70 per the README), a Code Mode endpoint with five meta-tools and an exact allowlist for servers the owner runs add back 10 (15). List tools page with bounded sizes, strip alert and incident lists to summary fields and clamp out-of-range counts, reporting each change under argument_adjustments (18). Tool errors return error_type and a message, with hints for plan-gated 404s, the pagination cap and replaced alert routing tools (16). Every tool sets readOnlyHint, destructiveHint and openWorldHint since 2.3.19, and writes set idempotentHint. create_incident has no idempotency key (15). Curated tools have no required parameters beyond record references and accept common aliases such as limit. Rootly lists REST SDKs for Go, Python and other languages (13).

Reliability New Relic MCP Server +12

New Relic MCP Server 60

Scored as a hosted MCP server. status.newrelic.com is an Atlassian Statuspage with 115 components across the US, EU and JP regions and no MCP component (20). history.rss holds seven incidents in the 90 days to 3 November 2026, among them delayed queries and alerts in the US for 49 minutes on 2 November, synthetics ping delays the same day, the JP entity platform unavailable for 67 minutes on 28 October, delayed US data and alerts from 19:24 to 22:04 UTC on 25 September, intermittent UI errors for two and a half hours the same night, a Salesforce support outage on 16 September and a 10-minute EU metric issue. Two regional incidents over an hour on the query and alert paths the server depends on, so one major (10). Published numbers, 2,000 tool calls an hour per user on the MCP server and 25 concurrent NerdGraph requests per user (15). NerdGraph answers 429 on concurrency with guidance to batch or pool, but no Retry-After is documented and nothing covers retries of MCP calls; the tools are reads, so idempotency doesn't arise (8). The pricing page lists support response SLAs, and the paid terms promise commercially reasonable efforts, so no availability SLA (0). Public preview on 4 November 2025, available to all accounts on 3 November 2026 with preview tools marked separately, but no dated GA notice was found (7). 20 + 10 + 15 + 8 + 0 + 7 = 60.

Rootly MCP Server 48

Scored as a hosted MCP server, the path the docs recommend. status.rootly.com is linked from the site and llms.txt. On 9 October it answered our reader with a bot check, so its components (15) and incident history (5) were unread. Rootly's Terms of Use bar crawling or scraping the Services, and this run pauses such hosts pending a ruling, so the 9 October readings are kept. The REST API behind the tools allows 3,000 read calls and 3,000 write calls a minute per API key, and 50 alert creations a minute. No separate limit for mcp.rootly.com was found (12). A 429 returns a JSON error with X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Used and X-RateLimit-Reset headers. No Retry-After, backoff guidance or idempotency keys were found (8). The pricing table lists "99.99 % Reliability" for on-call, and no SLA document was found (0). The hosted /mcp and /mcp-codemode endpoints carry no beta label. The README calls Code Mode experimental while the docs recommend it (8).

Security & auth New Relic MCP Server +11

New Relic MCP Server 76

OAuth 2.0 with the scopes observability:read, offline and offline_access, access tokens that expire after 5 minutes, refresh for 24 hours, revocation by deleting the user or turning off the organisation toggle, and the token acting as the user with no more than their roles; the alternative is a user API key in a header (28). A read scope, organisation toggles that default the API key, preview, Atlassian and AWS routes to off, an organisation-scoped role requirement, and no write tools in the list (16). Logs, error messages and trace attributes are untrusted text and no injection guidance was found (2). NrAuditEvent records sign-ins with IP addresses and NrdbQuery labels queries sent through the server, both queryable by the operator (13). security.txt pointing to a HackerOne programme, a published security policy citing SOC 2 Type 2 and ISO 27001 audits of its facilities and its own penetration testing, and an ISO 42001 certification announced on 29 September 2026; the trust centre itself renders through a script and was unread (17). 28 + 16 + 2 + 13 + 17 = 76.

Rootly MCP Server 65

OAuth 2 with dynamic client registration, PKCE with S256, one-hour access tokens, rotating refresh tokens, a revocation endpoint and :read and :write scopes per resource. The MCP server's resource metadata advertises a single all scope since 2.3.13, so MCP logins aren't narrowed by scope. API keys are global with a chosen role, team or personal, sent in the Authorization header (26). Delete operations are off by default and API key, user, role and webhook endpoints are excluded. Write tools are on by default for hosted connections, the documented read-only switch applies to servers the owner runs, and no confirmation step was found (11). Incident text, alert payloads and meeting transcripts are untrusted content, and no injection guidance was found (3). list_audits reads Rootly's audit log, which the pricing page lists under Enterprise (9). security.txt valid to 1 September 2027, a disclosure policy with safe harbour and response times, no paid bounty, SOC 2 Type II stated with the report on request, and dependency advisories recorded in the changelog. The server's own fixes in 2.3.22 and 2.4.0 carry no advisory, and OSV holds none for the package (16).

Payments & pricing New Relic MCP Server +10

New Relic MCP Server 30

No x402, MPP or L402 (0). The pricing page is public for the free tier and data ingest ($0.40 per GB beyond 100 GB), but MCP tools are metered as compute units with no per-call rate, and user and edition prices are quoted on request (10). The free tier includes MCP, 100 GB a month and one full platform user with no card (20). A person signs up in a browser and completes the OAuth flow (0). 0 + 10 + 20 + 0 = 30.

Rootly MCP Server 20

No x402, MPP or L402 (0). Plan prices are public. Essentials is $20 per product per user a month, with MCP and API access included, and Enterprise is by quote. No per-call price (10). No free tier. Self-serve sign-up starts a trial of about two weeks per the pricing page. The sign-up page answered with a bot check, so whether a card is needed wasn't established, and the line takes half marks (10). A person signs up in a browser and either logs in through OAuth or creates an API key (0). The package is free to run but needs a Rootly account, so the self-hosted rule doesn't apply.

Verdicts

New Relic MCP Server

OAuth with a read scope, 5-minute access tokens, role-bound calls and a queryable audit trail make this a safe read surface over an account's data, and the free tier includes it. 40 tools need tag filtering, the schemas aren't public, there is no per-call price, and no dated GA notice was found.

Rootly MCP Server

The server is open source under Apache-2.0, ships dated releases every few weeks, and has a slim profile and a Code Mode endpoint that cut the list of about 218 tools. Hosted connections expose write tools by default. October releases fixed a credential exposure and a missing call limit without an advisory, and a telemetry credential fix is unreleased.

Before you call either

New Relic MCP Server

  1. Connect with OAuth; an api-key header reaches only the core tools and the docs say the API key route works only where stated
  2. Send include-tags with the groups the task needs (for example discovery,data-access) to keep the tool list under 30
  3. Call list_available_new_relic_accounts first and pass the account id to every query; convert_time_period_to_epoch_ms turns phrases such as last 30 minutes into the epoch bounds the other tools take
  4. Stay under 2,000 tool calls an hour per user and 25 concurrent NerdGraph requests; a 429 clears as in-flight requests finish
  5. Ask the organisation administrator to turn on the Preview Tools, API Keys, Atlassian or AWS toggles in feature control manager before relying on those tools; they are off by default

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
  6. Move off https://mcp.rootly.com/sse before 20 November 2026, when Rootly removes the SSE transport
