## 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 2026-11-05.

- **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**: 72/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 930 tokens (~132/item across 7 items; 7 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% 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 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (7)

### `search_evidence_library` (~120 tokens)

Search the CliniAtlas evidence library

Find published CliniAtlas evidence answers matching a clinical question.

        Call this first for a clinical question: it is instant and has no daily limit.
        Returns question, summary and link for each match. The library
        is a set of worked answers to common questions; when one matches, use
        get_evidence_answer for the full answer. locale (for example de, fr, hr) returns
        translated answers where they exist.

Input parameters:

- `limit` (integer)
- `locale`
- `query` (string, required)

### `get_evidence_answer` (~69 tokens)

Get a CliniAtlas evidence answer

Full published answer: cited paragraphs, limitations and graded sources.

        Use a slug from search_evidence_library. Citation markers like [1] refer to the
        numbered sources. Show the sources and intended_use with the answer.

Input parameters:

- `locale`
- `slug` (string, required)

### `lookup_pubmed` (~53 tokens)

Look up a PubMed record

Citation metadata for a PubMed ID: title, journal, year, authors, DOI and design.

        Abstracts are not returned; follow pubmed_url to read them.

Input parameters:

- `pmid` (string, required)

### `lookup_eu_medicine` (~84 tokens)

Find an EU medicine and its SmPC

Centrally authorised EU medicines by brand name or active substance.

        Returns the EMA summary, authorisation status and ema_url, the EMA page whose
        Product information section holds the SmPC. Nationally authorised medicines are not
        in this register; check the national agency for those.

Input parameters:

- `limit` (integer)
- `name` (string, required)

### `search_medical_evidence` (~130 tokens)

Search medical evidence

Live search of PubMed, Europe PMC and clinical guidelines.

        Returns up to eight sources for a clinical or research question, each with its study
        type, evidence level and link, usually in about 20 seconds. It does not write an
        answer: cite the sources by number, or use ask_cliniatlas for a full cited answer.
        For an EU medicine's label or SmPC, use lookup_eu_medicine. Do not include patient
        identifiers. Searches are limited per user per day.

Input parameters:

- `locale`
- `question` (string, required)

### `ask_cliniatlas` (~167 tokens)

Ask CliniAtlas

Full CliniAtlas answer to a clinical or research question, with numbered citations.

        Searches the literature, guidelines and EMA documents and writes a cited answer, the
        same answer cliniatlas.com gives. Uncited parts are reported through grounding.
        Read-only: it changes nothing for the user. Full answers are rate limited per user
        per day (see free_answers_remaining_today), so check search_evidence_library first
        and use a published answer when one matches. Usually takes 35 to 50 seconds: if status is
        "running", call get_cliniatlas_answer with job_id. Do not include patient
        identifiers. For literature research and education, not individual care decisions.

Input parameters:

- `locale`
- `question` (string, required)

### `get_cliniatlas_answer` (~65 tokens)

Get a CliniAtlas answer

Collect the answer for a job_id returned by ask_cliniatlas.

        Waits up to about 40 seconds for the result. If status is still "running", call it
        again with the same job_id.

Input parameters:

- `job_id` (string, required)

## Common questions

### What is the CliniAtlas Evidence MCP server?

CliniAtlas Evidence is an MCP server listed in the public MCP registry as com.cliniatlas/evidence. Free medical evidence tools: graded CliniAtlas answers, PubMed metadata and EU SmPC links. This page covers its hosted endpoint (https://ydjbww4h7sfqc3sf2wcf26mfbq0bwvfu.lambda-url.eu-central-1.on.aws/public/mcp).

### Is the CliniAtlas Evidence MCP server safe to use?

CliniAtlas Evidence scores 82 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 CliniAtlas Evidence MCP server expose?

CliniAtlas Evidence exposes 7 tools: search_evidence_library, get_evidence_answer, lookup_pubmed, lookup_eu_medicine, search_medical_evidence, and 2 more. Their descriptions and schemas cost roughly 688 tokens of context every time the server is loaded.

### Does the CliniAtlas Evidence MCP server require authentication?

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

### Is the CliniAtlas Evidence MCP server still maintained?

CliniAtlas Evidence is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
