Nothing serious here today

Today is the operative word: we check Cerebro 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 1

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

estimate

estimate_project_cost

Break a software project description into modules and return a real dollar cost estimate per module: the cheapest model that clears a complexity-scaled quality bar for each one, plus the whole-project cost under every candidate model for comparison. architecture_template must be one of minimalista, clasica, state_of_the_art, hiperescalable, or left blank to auto-suggest one from the description. Requires x402 payment ($0.25 USDC on Base).

Cerebro — questions

Answers built from our own checks of this server.

What can Cerebro do?

It exposes 1 tools, read directly from the server on our last check. Among them: estimate_project_cost. 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 Cerebro working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 77 of 77 checks got a reply (100.0%), average response time 353 ms. The bar chart above shows every period we have measured.

How do I connect Cerebro?

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 Cerebro need an API key?

No. Cerebro completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Cerebro?

It answers our handshake in 353 ms on average, which is faster than 44% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
