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 0 of 91 checks got a reply (0.0%), average response time 353 ms. The bar chart above shows every period we have measured.

The registry lists Cerebro as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

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 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 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.
