Nothing serious here today
Today is the operative word: we check Utility Matrix every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 31
Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.

Use this when a user wants to benchmark their engineering team against DORA metrics, or classify their deployment frequency and lead time. Takes deploy frequency, lead time hours, change failure rate, and restore time. Returns Elite/High/Medium/Low tier classification per metric.
ec2

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 how much AWS data transfer or egress costs, or wants to estimate their monthly data transfer bill. Takes monthly transfer volume in GB. Returns estimated monthly egress cost using AWS tiered pricing.
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
Check a package name against a database of known CVEs. Returns vulnerability status, CVE ID, and severity for common packages (log4j, lodash, moment, axios, django, flask, pillow, etc.).
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, or wants to compare runner costs. Takes average job duration, jobs per run, monthly run count, and runner type. Returns monthly billing cost with runner multiplier breakdown.
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, recall, and 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 until an RI pays for itself. Takes On-Demand and RI monthly costs plus upfront fee. Returns break-even month and net savings over 1yr and 3yr terms.
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 and total requests over a period, returns burn rate multiple and time-to-exhaustion signal.
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 162 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 with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own credentials: it refuses anonymous clients.
Does Utility Matrix need an API key?
Yes. Every time we knock, Utility Matrix answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.
How fast is Utility Matrix?
It answers our handshake in 162 ms on average, which is faster than 75% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
