## 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 2026-09-29.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 67/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 762 tokens (~190/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 20/100
  - Stability observed for 6 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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (4)

### `screen_text` (~148 tokens)

Screen a draft before measuring it

Check whether a draft is ready before spending anything on it. Returns a 0 to 100 readiness reading, the suggested work type and up to six objective questions about what is still missing. Runs on a single cheap model and needs no API key, so it is the right first call when a user asks if a paper, case report, thesis chapter or teaching material is good enough yet. For the score that counts, with three reference models and eligibility for a citable record, call evaluate_text afterwards. Gatilho em português: "meu texto já está bom o suficiente".

Input parameters:

- `text` (string, required): Draft to screen, in the original language. Long texts are trimmed, never refused.

### `evaluate_text` (~275 tokens)

Evaluate a text against Crivum's criteria

Score a text against published academic criteria. Use when a user wants to know how strong a paper, case report, thesis chapter or teaching material is, or wants a reviewable score before submitting it somewhere. Returns a 0 to 100 score, a per criterion breakdown, the divergence between three reference models and whether the work qualifies for a citable DOI record. Does not accept recipes, operational legal documents, workout plans or other how to instructions. This is not peer review and the score is not an accreditation. Crivum reads any language and answers in the language of the text, and the criteria were calibrated in Portuguese and English, so comparing results across languages is a reading nobody has measured yet. Requires an API key. Gatilho em português: "quero saber a nota do meu texto antes de submeter".

Input parameters:

- `academic_level` (string): Academic level (T, G, E, M, D, P) or 'auto' to let Crivum infer it.
- `evaluation_id` (string): Caller-chosen id for idempotent re-calls. A new one is generated when omitted.
- `text` (string, required): Full text to score, in the original language.
- `title` (string, required): Work title.
- `work_type` (string, required): Work type key from get_criteria.

### `get_criteria` (~90 tokens)

Read Crivum's public scoring criteria

Return Crivum's public rubric by work type, the tier ladder, the thresholds, the minimum score for a citable record and what Crivum accepts and refuses, each with a version number. No API key required. Use before calling evaluate_text, or to show a user what a score decomposes into. Gatilho em português: "quais são os critérios da Crivum".

### `verify_record` (~180 tokens)

Verify a Crivum public record

List Crivum's published, citable records (title, authors, DOI when registered, tier and score). Pass exactly one of slug, doi or codigo to check one specific record, or omit all three to browse recent registrations. Rejects calls that pass more than one identifier at once, instead of matching either. No API key required. Gatilho em português: "esse trabalho já tem registro na Crivum".

Input parameters:

- `codigo` (string): Compact code shown on the record, e.g. 'Crivum MB74'.
- `cursor` (string): Opaque pagination cursor from a previous call.
- `doi` (string): Registered Crossref DOI.
- `limit` (integer): Page size when browsing (default 20).
- `slug` (string): Publication slug, e.g. from a crivum.org/p/ URL.
