## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `check_catalogue`

- 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
Catalogue registration check (batch ISRC lookup): checks up to 50 recordings at once against The MLC's bulk data (US mechanical royalties), and a larger catalogue in several calls. Returns each recording's verdict (registered, partial, nobody, conflict, unknown) with its confidence, MLC song code and any unclaimed share, plus a summary counting each verdict, the next step for each verdict found, and the as_of date of the MLC snapshot. Each row also lists the ISWCs and writers of the works MusicBrainz links to the recording. Invalid ISRCs are listed and skipped. It finds recordings whose music royalties may be unmatched or unclaimed. Findings from registration data, not legal advice or a statement of song ownership.
```

### `request_full_report`

- The name "request_full_report" says "request": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Ask for a full music royalties and registration review of a catalogue. Records the request (contact name, email, optional organisation, the catalogue's ISRCs and/or a description) so a person at TrackForge can follow up by email. It does not generate or send a report. Call it only when the user has asked for a follow-up and agreed to be contacted: consent_to_contact must be true.
```

## Only reads (2)

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

### `lookup_recording`

- The name "lookup_recording" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
ISRC lookup and music royalties registration check for one recording, with the song's rights data. Give exactly one of: an ISRC, a Spotify track link, a song title (optionally with the artist), or a YouTube link. Returns candidate recordings and MLC works, how each was matched and how confidently, and a verdict per recording: registered, partial (a share is unclaimed), nobody (no MLC work is linked), conflict, or unknown. Each verdict carries dated evidence (as_of, from The MLC's bulk data snapshot) and a factual next step. Also returns what MusicBrainz records for the recording: the linked works with their ISWCs, the writers and publishers with their IPI and ISNI numbers, the earliest release's album, date, label and catalogue number, and the MusicBrainz page. With full_record true it adds every release (label, catalogue number, country and date), performer and producer credits and related recordings; that answer is many times larger. When several matches are equally likely, ambiguous is true and all are returned. Findings from registration data, not legal advice or a statement of song ownership.
```

### `validate_cwr`

- The name "validate_cwr" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
CWR validation: checks the text of a CWR 2.1 (Common Works Registration) file used to register songs with music royalties societies such as The MLC, PRS for Music / ICE, SACEM or CMRRA. Returns whether the file is valid, error and warning counts, and each issue with its line, rule, plain-language explanation and how to fix it. Pass the file content as ASCII text, up to 256 KB; larger files can be uploaded at https://trackforge.studio/cwr-tool. Validation does not guarantee acceptance by a society. The file is not stored.
```
