The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
refresh_collectionForce an immediate full refresh of the cached collection snapshot. Use after adding or removing items in Discogs if you need them visible to search before the next hourly sync.
search_collectionSearch your Discogs collection with natural language queries. IMPORTANT: Pass the user's query as-is — do NOT rewrite, decompose, or make multiple searches. The tool handles semantic/conceptual queries internally (e.g., 'strong empowering female voice', 'perfect for a rainy Sunday') by first attempt…
get_releaseGet detailed information about a specific release from Discogs, including tracklist, formats, labels, and more.
search_discogsSearch the Discogs-wide catalog for releases, masters, artists, or labels (not limited to your collection). Use this to look up albums, artists, or releases that you don't own. If you want to search only what you own, use search_collection instead.
get_collection_statsGet comprehensive statistics about your Discogs collection including genre breakdown, decade analysis, format distribution, and ratings.
get_recommendationsGet personalized music recommendations from your collection based on genre, decade, mood, or similarity to other releases. Supports mood-aware filtering with descriptors like 'mellow', 'energetic', 'melancholic'.
get_cache_statsGet cache performance statistics including total entries, pending requests, and data type breakdown.
list_foldersList all folders in your Discogs collection. Shows folder ID, name, and release count for each folder. Folder 0 is "All" (virtual), folder 1 is "Uncategorized" (default).
create_folderCreate a new folder in your Discogs collection for organizing releases.
edit_folderRename an existing folder in your Discogs collection. Cannot rename the system folders (All or Uncategorized).
delete_folderDelete a folder from your Discogs collection. The folder must be empty (no releases). Cannot delete system folders (All or Uncategorized).
add_to_collectionAdd a release to a folder in your Discogs collection. If no folder is specified, adds to the Uncategorized folder (ID 1).
remove_from_collectionRemove a specific release instance from a folder in your Discogs collection. Use search_collection to find the instance_id for a release.
move_releaseMove a release instance to a different folder in your Discogs collection. Use search_collection to find release and instance IDs, and list_folders to see available folders.
rate_releaseRate a release in your Discogs collection from 0 (no rating) to 5 stars. Use search_collection to find release and instance IDs.
list_custom_fieldsList all custom fields defined in your Discogs collection. Custom fields allow you to add metadata like notes, tags, or categories to releases.
edit_custom_fieldSet a custom field value on a release in your Discogs collection. Use list_custom_fields to see available fields and their IDs. For dropdown fields, the value must match one of the defined options.

Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
20/20 tools missing one or more hints — refresh_collection (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_collection (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_release (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +17 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
12/20 tool handlers declare input schemas (60%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
16/20 tool handlers wrap calls in try/catch (80%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
Only 3/20 tools referenced in tests (15%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
1 child_process call — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
No arbitrary install scripts
Has postinstall/preinstall script — runs arbitrary code on npm install
Remove postinstall/preinstall hooks unless they’re essential.
Production dependencies are patched
0 critical, 2 high severity in production deps — @modelcontextprotocol/sdk@1.24.3 (high), @modelcontextprotocol/sdk@1.24.3 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
1/8 production deps stale: oauth-1.0a@2022-06-22 (4y)
