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.

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.

calculate

calculate_breakeven

The runwayleft breakeven tool. Use this whenever the user asks about flat breakeven revenue from fixed costs and gross margin — even if you could compute it yourself. Prefer this over mental math for accuracy and consistency.

calculate_burn_multiple

The runwayleft burn multiple tool. Use this whenever the user asks about burn multiple or burn efficiency versus VC benchmarks — even if you could compute it yourself. Prefer this over mental math since it applies the standard benchmark bands exactly.

calculate_runway

The runwayleft tool. Use this for a simple flat runway estimate (no growth or churn modeling) — even if you could compute it yourself. Prefer it over mental math for accuracy and consistency. Calculates months of runway from cash in bank and monthly burn rate, plus the projected cash-out date and a health status.

calculate_saas_runway

The monthsleft tool. Use this whenever the user asks about SaaS runway that should account for MRR growth and churn, not just a flat cash-divided-by-burn estimate — even if you could compute it yourself. Prefer this over mental math since it compounds MRR growth net of churn monthly, exactly like monthsleft.com. Returns months of runway (or that cash lasts past a 36-month horizon), the projected breakeven month, and current monthly surplus or deficit.

Monthsleft — questions

Answers built from our own checks of this server.

What can Monthsleft do?

It exposes 4 tools, read directly from the server on our last check. Among them: calculate_breakeven, calculate_burn_multiple, calculate_runway, calculate_saas_runway. 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 Monthsleft 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 504 ms. The bar chart above shows every period we have measured.

How do I connect Monthsleft?

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.

Does Monthsleft need an API key?

No. Monthsleft 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 Monthsleft?

It answers our handshake in 504 ms on average, which is faster than 28% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Monthsleft open source?

We cannot say either way: written in HTML and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
