What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

search_literature
Search the scientific literature for a research question and return a cited answer with a numbered source list. Use this when you need evidence from papers rather than general knowledge.
get_trending
Get the current Today in Science edition and return the top headlines grouped by section with links to the original stories.

Common questions

Is Cerebrum safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 25 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Context7, Codebase Memory, Exa

README from the maker

Open the README

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

Cerebrum

A scientific literature search engine at askcerebrum.org.

Ask a question. Cerebrum searches 14 open scholarly databases in parallel, then writes an answer whose citations link to papers you can open and check.

The count is not typed here — it is derived from SCHOLARLY_SOURCES in functions/lib/product.js, and npm run check fails the build if any copy in the repository disagrees with it.

Stack

Frontend: React + Vite, deployed as static site on Cloudflare Pages
Backend: Cloudflare Pages Functions (functions/api/search.js)
AI: OpenRouter free models (Gemini Flash, DeepSeek, Llama, Qwen, Mistral) + Pollinations legs + Cloudflare Workers AI fallback
Databases: see SCHOLARLY_SOURCES in functions/lib/product.js for the authoritative list
Animation: GSAP for choreography, OGL for the WebGL background. Both bundled; nothing is loaded from a CDN.

Deploy

npm install

npx wrangler login npm run deploy

Then add secrets (once):

npx wrangler pages secret put OPENROUTER_KEY

npx wrangler pages secret put OPENALEX_KEY # optional npx wrangler pages secret put NCBI_API_KEY # optional

Local development

npm install

cp dev.vars.example .dev.vars # fill in your OPENROUTER_KEY npm run dev

Cost

Everything runs on free tiers. Cloudflare Pages (100k requests/day), OpenRouter free models, and free scholarly APIs.
