Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 4

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

meter
get_meter_balance
Get the current prepaid credit balance of a meter, in SGD.
get_meter_usage
Get up to 7 days of usage for an NUS meter, with spending analysis, month-to-date spending, and how long the balance may last. Amounts are in SGD. Dates are as EVS reports them, with no time zone, and recent days may be missing. Not available for SUTD meters.
recent
get_recent_topups
Get up to 10 recent top-ups for a meter. To confirm a payment, look for a top-up with the same amount dated after the createdAt of its link, and with no status showing it failed. Earlier top-ups can have the same amount, so always check the date. Dates have no time zone and appear to be Singapore time (UTC+8), while createdAt is ISO 8601. If nothing matches, the payment may not be recorded yet or may have failed: check again later, and have the user check their card statement before paying again.
topup
get_topup_link
Create a link to the secure top-up page, for the user to open and pay by card themselves. Creating the link charges nothing. Refuses a meter EVS doesn't recognise. If EVS can't be reached, meterVerified is false, so ask the user to check the meter on the page. NUS allows $6-$50 and SUTD allows $10-$50.

EVS Meter Tools — questions

Answers built from our own checks of this server.

What can EVS Meter Tools do?
It exposes 4 tools, read directly from the server on our last check. Among them: get_meter_balance, get_meter_usage, get_recent_topups, get_topup_link. 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 EVS Meter Tools 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 543 ms. The bar chart above shows every period we have measured.
How do I connect EVS Meter Tools?
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 EVS Meter Tools need an API key?
No. EVS Meter Tools completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is EVS Meter Tools?
It answers our handshake in 543 ms on average, which is faster than 20% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is EVS Meter Tools open source?
The code is open source: it is published under the MIT licence, written in JavaScript and 2 stars on GitHub. The licence covers the code in the repository, not the hosted service at nusaircon-production.up.railway.app, which runs on its operator's own terms.
