AniList MCP Server

Get recommendations for a title

get_recommendations_for_media
Read-only

Fetches anime/manga recommendations similar to a given AniList title, ranked by rating, and can exclude titles already on your own list.

Instructions

List anime/manga AniList users recommend as similar to a given title, ranked by rating (highest first). Use search_media first to resolve the title to its AniList ID. Each result's mediaRecommendation.mediaListEntry (requires login) shows whether it's already on your own list — set excludeInList: true to drop those from the fetched page instead of checking each one yourself (a local post-fetch filter: AniList's own onList filter applies to the source title, not the recommended one).

Input Schema

NameRequiredDescriptionDefault
pageNoPage number for pagination. AniList's paginated connections (search results, a title's characters/staff/reviews, activity feeds, forum comments) reject a page whose page × perPage exceeds ~5000 entries with an upstream error, so paging that deep fails rather than returning more results.
mediaIdYesAniList ID of the anime/manga to get recommendations for.
perPageNoResults per page (max 25, AniList's own ceiling — it silently clamps anything higher).
excludeInListNo[Requires login] Omit recommendations already on your own list. Filtered after fetching this page, so a page can come back with fewer than `perPage` results — not an error, just fewer new ones on that page. Errors if not logged in, since there's no list to check against.

Output Schema

TDQS

A4.5/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond the readOnlyHint and openWorldHint annotations, the description discloses ranking order, login requirements for mediaListEntry, and that excludeInList is a local post-fetch filter rather than AniList's own onList filter. It also notes the consequence that a page may return fewer than perPage results, which is useful behavioral context not covered by the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is three tight sentences with no filler, and the core purpose and ID-resolution prerequisite are front-loaded. The parenthetical about onList is dense but earns its place by preventing a concrete filtering mistake.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only listing tool with an output schema and full annotations, the description covers everything an agent needs: what is returned, ranking order, prerequisite ID resolution, login-dependent fields, and excludeInList gotchas. Pagination and numeric limits are already handled by the schema descriptions.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3, but the description adds meaningful semantics beyond the schema by explaining that excludeInList filters after fetching and that AniList's native onList filter applies to the source title, not the recommended one. It also clarifies mediaId's role by directing the agent to search_media for resolution.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: list recommendations for a given anime/manga title, ranked by rating. It clearly separates this from search_media by instructing the agent to use search_media first for ID resolution, and the scoped wording distinguishes it from the singular get_recommendation sibling.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives clear usage context by telling the agent to use search_media first to resolve a title to an AniList ID, and it explains when to set excludeInList. It does not explicitly name when not to use this tool or compare it against get_recommendation, so it falls short of full when/when-not guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
