## Findings

No check matched anything in these tool definitions.


## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `changes_since`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Certifications created, updated, deactivated, reactivated or removed since a date (history starts at the first ingestion run). Filter by change type, register or NSF code. Example (FR): « Quelles fiches informatique (NSF 326) ont changé depuis le 1er juillet ? »
```

### `check_habilitation`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Is a given SIRET (or SIREN) habilitated for a certification, and for which role: 'former' (train), 'evaluer' (organise assessment) or both? Also detects when the SIRET is the certifier itself. Habilitation is effective only if the certification is active AND the partner state is 'Actif'. Example (FR): « Le SIRET 80875076400025 est-il habilité sur le RNCP 35419 ? »
```

### `check_validity`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Is this certification currently registered (active) and until when? Returns status, expiry date, remaining days, delivery deadline, replacement certification(s) and an estimated CPF eligibility (a registered active certification is eligible in principle; the training organism must still be habilitated and referenced). Example (FR): « Le RNCP 35419 est-il encore actif ? Jusqu'à quand ? »
```

## Only reads (6)

Looks things up and changes nothing. Claude Code: allow.

### `compare_certifications`

- The name "compare_certifications" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Side-by-side comparison of two certifications: level, status, certifiers, NSF/ROME overlap, number of blocs and lexical overlap of blocs (Jaccard on skill terms) and, for each bloc of A, the closest bloc of B (overlap coefficient). Example (FR): « Compare le RNCP 36490 et le RNCP 37873. »
```

### `get_certification`

- The name "get_certification" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Full structured sheet of one RNCP or RS certification: title, level, status and expiry, certifier(s), activities, attested skills, NSF/ROME/Formacode codes, access routes, legal texts, replacements, statistics, official URL. Long texts are truncated to 4000 chars unless full=true. Example (FR): « Donne-moi la fiche RNCP 35419 et ses compétences attestées. »
```

### `get_data_status`

- The name "get_data_status" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Source dataset date, ingestion run, counts (total/active/RNCP/RS/blocs/partners) and age of the data in days. Call this to tell the user how fresh the answers are. Example (FR): « De quand datent les données RNCP ? »
```

### `list_blocs`

- The name "list_blocs" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Blocs de compétences of an RNCP certification (code RNCPxxxxxBCyy, title, skills, assessment methods), in the order and wording expected by EDOF / Mon Compte Formation forms. RS certifications have no blocs. Example (FR): « Liste les blocs de compétences du RNCP 37674 à renseigner dans EDOF. »
```

### `list_partenaires`

- The name "list_partenaires" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Training organisms habilitated on a certification (name, SIRET, role former/evaluer/both, state, dates). Paginated; filter by SIRET/SIREN prefix. Example (FR): « Quels organismes sont habilités sur le RNCP 37674 ? »
```

### `search_certifications`

- The name "search_certifications" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Full-text search (BM25 + French synonyms) over the French national registers of professional certifications: RNCP (diplomas, titles, CQP) and RS (specific register: skills certificates, habilitations). Filter by register, level (3-8), NSF or ROME code. Returns ranked matches with status and expiry date; use get_certification for details. Example (FR): « Quelles certifications de niveau 6 en cybersécurité sont actives ? »
```
