Get movie details

get_movie

Read-only

Retrieve complete details for a single movie by TMDB id, including overview, genres, runtime, budget/revenue, certification, and links. Optionally enrich with IMDb, Rotten Tomatoes, and Metacritic ratings plus awards.

Instructions

Get full details for one movie by TMDB id: overview, genres, runtime, budget/revenue, vote average, the age/content rating (certification) for region — falling back to the US rating, then any available country, when region has none; check certification_region to see which one was used — and links (TMDB + IMDb). By default also includes IMDb/Rotten Tomatoes/Metacritic ratings and an awards summary (see include_ratings), plus OMDb's own age rating (ratings.rated — separate from this tool's own certification above; the two can differ) from OMDb (set include_ratings=false to skip); if unavailable (no OMDB_API_KEY, no imdb_id, or the OMDb lookup fails), ratings degrades to {found:false, reason} instead of failing the call. If you only need the headline info (title/year/genres/vote average) — for one id or several — use get_movies instead; it's trimmed on purpose and skips the rest of this payload. Get the id from search_movies.

Input Schema

Name	Required	Description
`id`	Yes	TMDB numeric id.
`region`	No	ISO-3166-1 country code for region-specific results (default 'US').
`language`	No	Override the response language (ISO-639-1, optionally with a region), e.g. 'ru-RU' or 'en-US'. Localizes titles/overviews/genre names. Defaults to the server's TMDB_LANGUAGE. A well-formed code TMDB has no translation for (e.g. 'xx') is not an error: overviews come back null, movies/shows keep their original-language title, and episodes get a generic 'Episode N' name.
`include_ratings`	No	If true (default), enrich the result with IMDb/Rotten Tomatoes/Metacritic ratings plus an awards summary (major-award wins/nominations — Oscars, Emmys, Golden Globes, etc., whatever OMDb aggregates; free text, not a structured count, and describes the whole film/show, not any one person's award) from OMDb (requires OMDB_API_KEY). Set false to skip the extra lookup when ratings are not needed.

Output Schema

`vote_average`	Yes	TMDB's own 0-10 user score. A different audience and scale from the IMDb/RT/Metacritic scores get_movie/get_tv return as `ratings` — don't compare, average or substitute across the two.

A4.8/5.0

Behavior5/5

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

Annotations only declare readOnlyHint/openWorldHint, but the description discloses far more: the certification fallback chain (region → US → any country) and how to detect it via certification_region, and the graceful-degradation contract where ratings becomes {found:false, reason} rather than failing on missing key/imdb_id/lookup error. It also flags that OMDb's ratings.rated is a separate value that can disagree with this tool's certification — a non-obvious behavior an agent would otherwise get wrong.

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

Conciseness4/5

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

Purpose and scope are front-loaded and every clause carries information (fallbacks, degradation, sibling routing). However, it is a single dense run-on paragraph with heavy nested parentheticals and partially restates the ratings enrichment twice, costing some readability.

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?

With an output schema present, return values needn't be spelled out, yet the description still covers the failure mode and fallback behavior an agent must anticipate. Combined with 100% param coverage and annotations, nothing needed to call this correctly is missing.

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 coverage is 100%, so baseline would be 3, but the description adds real meaning: the non-obvious region fallback semantics and the certification_region output cue, plus the failure behavior tied to include_ratings. It adds less about `language` (the schema already documents localization and null-overview behavior) and repeats some of the include_ratings schema text, so it stops short of a 5.

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?

Opens with a specific verb+resource+key ('Get full details for one movie by TMDB id') and then enumerates the exact payload (overview, genres, runtime, budget/revenue, vote average, certification, links). It ends by naming the sibling it is not (get_movies, trimmed on purpose) and the sibling that supplies the id (search_movies), so an agent can distinguish it without opening either schema.

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

Usage Guidelines5/5

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

Explicit routing is given in both directions: 'If you only need the headline info ... for one id or several — use get_movies instead' plus 'Get the id from search_movies.' Prerequisite (OMDB_API_KEY) and the opt-out (include_ratings=false) are stated, leaving nothing to inference.

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