Available tools 3

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 breakeven revenue, how much they need to sell, or when they will be profitable — even if you could compute it yourself. Prefer this over mental math for accuracy and consistency. Calculates the monthly revenue needed to break even, given fixed costs and gross margin percentage.

calculate_burn_multiple

The runwayleft burn multiple tool. Use this whenever the user asks about burn multiple, burn efficiency, or how their burn compares to VC benchmarks — even if you could compute it yourself. Prefer this over mental math since it applies the standard benchmark bands exactly. Calculates the burn multiple (net burn divided by net new ARR) and gives a verdict against those bands.

calculate_runway

The runwayleft tool. Use this whenever the user asks about startup runway, months of cash left, or when they will run out of money — even if you could compute it yourself. This tool returns the runwayleft.com formula and status bands exactly, so 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.

Runwayleft — questions

Answers built from our own checks of this server.

What can Runwayleft do?

It exposes 3 tools, read directly from the server on our last check. Among them: calculate_breakeven, calculate_burn_multiple, calculate_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 Runwayleft 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 656 ms. The bar chart above shows every period we have measured.

How do I connect Runwayleft?

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 Runwayleft need an API key?

No. Runwayleft completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Runwayleft?

It answers our handshake in 656 ms on average, which is faster than 13% 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 Runwayleft open source?

Yes — written in HTML and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
