## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-18.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 78/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 92 tokens (~46/item across 2 items; 2 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 13/100
  - Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 40/100
  - Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28.

## Install

### How do I install the Cerebrum MCP server?

Cerebrum is a hosted endpoint at https://askcerebrum.org/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

```bash
claude mcp add --transport http org-askcerebrum-cerebrum 'https://askcerebrum.org/mcp'
```

{
  "mcpServers": {
    "org-askcerebrum-cerebrum": {
      "url": "https://askcerebrum.org/mcp"
    }
  }
}
```

### VS Code

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-10-17 (score 71, +1)

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-10-15 (score 70, +1)

- [functional improvement] Stability: unverified → 0.03

### 2026-10-14 (score 69)

First indexed and scored.

## Common questions

### What is the Cerebrum MCP server?

Cerebrum is an MCP server listed in the public MCP registry as org.askcerebrum/cerebrum. Search the scientific literature and get a cited answer, plus the Trending in Science edition. This page covers its hosted endpoint (https://askcerebrum.org/mcp).

### Is the Cerebrum MCP server safe to use?

Cerebrum scores 71 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Cerebrum MCP server expose?

Cerebrum exposes 2 tools: search_literature, get_trending. Their descriptions and schemas cost roughly 92 tokens of context every time the server is loaded.

### Does the Cerebrum MCP server require authentication?

No. We connected to Cerebrum without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Cerebrum MCP server still maintained?

Cerebrum is still listed as active in the MCP registry. We last reached this channel on 18 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
