Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
alert
alert-fatigue-calculator
Use when a user asks about alert noise, alert fatigue, or on-call burden from non-actionable alerts. Given weekly alert volume, actionable %, engineer count, and avg resolution time, returns noise rate, wasted hours, and fatigue tier.
apdex
apdex-score-calculator
Use this when a user asks about their Apdex score or wants to measure user satisfaction with response times. Takes satisfied, tolerating, and total request counts; satisfied plus tolerating may not exceed total. Returns the Apdex score (0–1) and its rating on the published five-band scale: excellent, good, fair, poor or unacceptable.
availability
availability-sla-calculator
Use this when a user asks what a specific availability percentage (like 99.9% or 99.99%) means in downtime minutes per month or year. Converts availability SLA percentage to exact downtime budgets: annual, monthly, weekly, and daily.
call
on-call-burden-calculator
Use when a user asks about on-call load or burnout risk. Uses team size, rotation length, and hourly rate exactly as the browser calculator does.
canonical
canonical-url-auditor
Audit a page URL against its canonical tag. Detects missing canonical, self-referencing canonical, and relative URL issues.
certificate
certificate-expiry-checker
Assess certificate expiry risk given a domain and days remaining. Returns risk level (OK, WARNING at <30 days, CRITICAL at <7 days, EXPIRED at <0).
change
change-failure-rate-calculator
Use when a user asks about change failure rate or DORA CFR. Given total and failed deployments, returns failure rate percentage and DORA tier.
cloud
cloud-waste-calculator
Use when a user asks about cloud waste, idle resources, or unattached storage. Given monthly cloud bill and idle/oversized percentages, returns waste estimate and tier.
cluster
cluster-capacity-calculator
Use this when a user asks for Kubernetes cluster capacity. Uses the same node vCPU, node memory, node count, system reserve, and target utilization model as the browser calculator.
connection
connection-pool-calculator
Use this when a user asks how many database connections to configure. Uses the same max_connections, app server count, database cores, average query duration, and peak RPS model as the browser calculator.
cost
query-cost-estimator
Estimate PostgreSQL sequential-scan and index-scan cost from table rows, table pages, selectivity, and storage type. Uses the same four-input model as the browser calculator.
deployment
deployment-frequency-calculator
Use when a user asks about deployment frequency or DORA deploy cadence.
detect
detect-secrets-scanner
Scan text (config, code, env files) for leaked API keys, tokens, passwords, and private keys, plus static code-risk findings such as dynamic code execution, wildcard CORS, unsafe HTML sinks, process spawning and removed security guards. Returns findings with redacted matches and severity classification.
dockerfile
dockerfile-linter
Lint a Dockerfile against a rule-based subset of Hadolint checks: untagged or :latest base images, interactive or unpinned apt-get installs, apt list cleanup, apk cache, ADD for local files, shell-form CMD/ENTRYPOINT, running as root and a missing HEALTHCHECK. Lines joined with a trailing backslash count as one instruction, and each issue reports its line in the original file.
dora
dora-metrics-calculator
Use this when a user wants to benchmark an engineering team against DORA metrics. Takes deploys per month, lead time in hours, change failure rate in percent and, optionally, time to restore in hours. Classifies each metric as elite, high, medium or low against fixed benchmark bands; an omitted restore time is reported as unknown and the overall profile is marked partial rather than assumed.
ec2
ec2-cost-calculator
Use when a user asks about EC2 cost. Given instance type and hours, returns monthly cost and DO-equivalent savings estimate.
egress
egress-cost-calculator
Use this when a user asks about monthly internet egress cost from daily request volume, average response size, provider, and CDN offload. Uses the same model as the browser calculator.
error
error-budget-calculator
Use this when a user asks about their SLO error budget, remaining error budget, or burn rate. Given SLO percentage and window, returns budget minutes remaining, burn rate multiplier, and status (Under budget / Elevated / ALERTING).
incident
incident-cost-calculator
Use this when a user asks what an outage or incident cost, or wants to calculate the financial impact of downtime. Takes hourly revenue, downtime duration, and affected percentage. Returns revenue impact, engineering cost, and total incident cost in dollars.
known
known-vulnerability-checker
Historical curated package-name advisory reference only. Matches older CVE examples for common packages; does not query live feeds or evaluate installed version ranges, so it never proves a package is currently vulnerable or safe.
kubernetes
kubernetes-manifest-linter
Lint a Kubernetes manifest (YAML) for common issues: missing resource limits, missing health checks, :latest tag usage, privileged containers. Returns issue list and severity.
mttr
mttr-calculator
Use when a user asks about MTTR or DORA recovery time. Takes incident timestamps (string lines "start,detected,resolved" or array of {start,detected,resolved}).
pipeline
pipeline-cost-calculator
Use this when a user asks how much their GitHub Actions CI/CD pipeline costs per month. Takes average job duration in minutes, jobs per run, runs per month and the runner label (ubuntu-latest, windows-latest, macos-latest or self-hosted; matched case-insensitively). Uses GitHub list prices for standard hosted runners effective 1 Jan 2026 and GitHub Free's 2,000 included minutes for private repositories, drawn at list price. Self-hosted minutes carry no GitHub charge.
precision
precision-recall-f1-calculator
Use this when a user asks about their ML model precision, recall, F1 score, or F-beta score. Takes precision and recall as fractions from 0 to 1 and an optional beta weight. Returns F1, F-beta, and interpretation of the precision-recall tradeoff.
rate
rate-limit-utilization-calculator
Calculate API rate limit utilization given current request count and limit. Returns utilization percentage, buffer, safety status, and risk level (OK at <80%, WARNING at 80-95%, CRITICAL at >95%).
reserved
reserved-instance-breakeven
Use this when a user asks whether to buy Reserved Instances or stay on On-Demand, or how long an RI takes to pay for itself. Takes On-Demand and RI monthly costs plus optional upfront fees (0 when omitted). Judges the 1-year and 3-year terms separately and returns each break-even month and net saving. It recommends a term only when that term saves money over its own length, and prefers 3 years only when it beats three 1-year terms over 36 months at current prices.
rightsizing
rightsizing-calculator
Use when a user asks about instance rightsizing or overprovisioned compute.
slo
slo-burn-rate-calculator
Use this when a user asks how fast they are burning their error budget, or whether their current error rate will exhaust their SLO window. Takes error count, total requests, SLO target, and observation window. Returns burn rate and budget consumption per hour.
software
software-purchase-risk-calculator
Use when a user asks about risk of a software purchase or SaaS commitment.
terraform
terraform-plan-cost-estimator
Use when a user asks to estimate monthly cost of a Terraform plan.
total
total-cost-of-ownership-calculator
Use when a user asks about TCO or multi-year SaaS cost.

Utility Matrix — questions
Answers built from our own checks of this server.
What can Utility Matrix do?
It exposes 31 tools, read directly from the server on our last check. Among them: alert-fatigue-calculator, apdex-score-calculator, availability-sla-calculator, canonical-url-auditor, certificate-expiry-checker, change-failure-rate-calculator and 25 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is Utility Matrix working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 289 ms. The bar chart above shows every period we have measured.
How do I connect Utility Matrix?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Utility Matrix need an API key?
No. Utility Matrix completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 31 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Utility Matrix?
It answers our handshake in 289 ms on average, which is faster than 49% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
