@cyanheads/tvmaze-mcp-server
Search TVmaze shows, next episodes in your timezone, episode guides, daily TV schedules, and cast via MCP. STDIO or Streamable HTTP.
7 Tools
Overview
Television data from TVmaze โ a community-maintained database of series, episodes, air times, and credits, served by a keyless public API. Find a show by title or by its IMDb, TheTVDB, or TVRage id, then read its profile, season episode guides, and cast, or ask when the next episode airs in a viewer's timezone. A whole date works as the starting point too: what a country's networks broadcast that day, what the global streaming services released, or both merged. Runs as a stdio process or a local Streamable HTTP server.
| Tool | Description |
|---|
tvmaze_search_shows | Fuzzy title search returning up to 10 shows with channel, status, genres, rating, and external catalog ids |
tvmaze_get_show | Full profile for one TVmaze id โ weekly slot, season list, and the previous and next episode |
tvmaze_lookup_show | Resolve a show from its IMDb, TheTVDB, or TVRage id into the matching TVmaze profile |
tvmaze_get_next_episode | When a show's next episode airs, by TVmaze id or title, converted to a viewer timezone |
tvmaze_get_episodes | Episode guide for one season or the whole run, with air times, runtimes, and synopses |
tvmaze_get_schedule | Episodes airing on a date โ broadcast and cable networks in one country, streaming services, or both |
tvmaze_get_cast | A show's credited cast and the characters they play, optionally crew; or one episode's guest cast |
Capability reference
- Fuzzy match on
query against every show title, so minor misspellings still resolve
- Hard-capped at 10 rows by the source with no pagination; enrichment echoes the query and reports
shown / cap, and the notice routes a saturated or empty result to a narrower title or to tvmaze_lookup_show
- Rows carry the shared show summary plus
match_score, which is comparable only within one result set
show_id from tvmaze_search_shows, tvmaze_lookup_show, or a schedule row; optional IANA timezone for the rendered episode times
- Returns the full profile โ
schedule_days / schedule_time, official_site, externals โ with every season and the next_episode / previous_episode the source has
- A
Running show with nothing announced comes back with a notice pointing at previous_episode rather than a silently empty field
- An unknown
show_id fails as a typed show_not_found
- One
source of three โ imdb (a tt id), thetvdb, or tvrage (defunct, present only in older records) โ paired with external_id
- A show absent from TVmaze is a result, not an error:
found: false plus guidance routing to tvmaze_search_shows
- Echoes
source and external_id; a hit returns the same show summary the search tool does
by: "id" takes a TVmaze id; by: "title" resolves a title through a stricter single-match search than tvmaze_search_shows uses
- Air times render in the requested IANA
timezone; time_known: false means the source announced no clock time, so only the date is reliable
- Typed
miss_reason โ show_not_found on the title arm, no_scheduled_episode for a series between seasons, the latter still carrying previous_episode
- A
show_id that resolves to nothing throws show_not_found_by_id; an unresolvable title is a miss
season lists one season (the cheaper path); omit it to walk the whole run
include_specials defaults to false; a season listing reports how many specials it filtered out
limit 1โ250 (default 50) with cursor / next_cursor pagination and has_more; enrichment carries the pre-page totalCount
- A
season_not_found failure names the seasons that do exist
scope picks the feed: linear is one country's broadcast and cable networks plus its own streaming services, streaming is global services when country is omitted and that country's local ones when it is given, all merges both across three upstream requests
date defaults to today in the requested timezone; country is ISO 3166-1 alpha-2 (the United Kingdom is GB) and falls back to the configured default for linear and all
- Entries carry
feed (linear / streaming) alongside the episode and its show; a merged query dedupes and sorts by airstamp
applied_feeds names exactly which upstream feeds answered, e.g. ["linear:GB","web:GB","web:global"]; one feed failing degrades to a notice instead of failing the call
limit 1โ250 (default 50) with cursor pagination โ a country day runs to roughly 50 broadcast entries, the global streaming feed to over 120
scope: "show" returns the main cast with character names, plus crew when include_crew is set; scope: "episode" returns that episode's guest cast
- Cast credits carry
as_self and voice_only; crew credits carry credit_type and no character
- TVmaze records no recurring-versus-guest distinction on a show's cast list, so absence from it is not evidence a performer never appeared โ check an episode's guest cast
- Missing credits arrive as a notice, not an error; community coverage thins on smaller titles
Features
Built on @cyanheads/mcp-ts-core: stdio and Streamable HTTP transports, pluggable auth (none / jwt / oauth), swappable storage (in-memory, filesystem, Supabase, Cloudflare KV/R2/D1), structured logging with optional OpenTelemetry tracing.
TVmaze-specific:
- Keyless โ no account, no API key, and every tool works on a fresh install with nothing configured
- Upstream requests are paced under the documented per-IP budget with bounded concurrency and a 429 cooldown that honors
Retry-After, in front of an in-process response cache shared across tenants
- Air times are computed from
airstamp alone; the airdate / airtime pair is the broadcaster's programming-day convention and diverges by a full day on overnight slots
- Community-authored HTML summaries are stripped to plain text, never rewritten or spell-corrected
Agent-friendly output:
- No fabricated clock times โ a record with no announced broadcast time reports
time_known: false and a date only, and absent upstream fields render as Not available rather than 0 or ""
- Typed error contracts on every tool โ a
reason plus a recovery hint that reaches both structuredContent and the text surface
- Resolution misses are results, not failures:
tvmaze_lookup_show and the title arm of tvmaze_get_next_episode return found: false with guidance for the next call
- Enrichment states what a call actually covered โ the echoed query,
applied_feeds, pre-page totals, and truncation against the source's own caps
Data and licensing
Data comes from TVmaze and is licensed CC BY-SA. Credit TVmaze as the source and keep the url field that every show, episode, and person record carries โ linking back is what satisfies attribution. Under ShareAlike, an adaptation of this data must be shared under the same licence.
TVmaze rate-limits to at least 20 calls every 10 seconds per IP address and answers a burst past that with HTTP 429; the server paces itself under that budget and backs off when one arrives. Upstream caches its output for 60 minutes, so a schedule change or a newly announced episode can take up to an hour to appear; the local response cache (TVMAZE_CACHE_TTL_S, default 300 s) sits well inside that window.

Running the server
Local development
-
Build and run:
bun run rebuild
bun run start:stdio
bun run start:http
-
Run checks and tests:
bun run devcheck
bun run test
bun run lint:mcp
Docker
docker build -t tvmaze-mcp-server .
docker run --rm -p 3010:3010 tvmaze-mcp-server
The Dockerfile defaults to HTTP transport, stateless session mode, and logs to /var/log/tvmaze-mcp-server. OpenTelemetry peer dependencies are installed by default โ build with --build-arg OTEL_ENABLED=false to omit them.

docs/ | Design document and the generated project tree. |
Development guide
See CLAUDE.md/AGENTS.md for development guidelines and architectural rules. The short version:
- Handlers throw, framework catches โ no
try/catch in tool logic
- Use
ctx.log for request-scoped logging; every upstream call goes through TvmazeService, never fetch from a handler
- Register new tools in the
createApp() arrays in src/index.ts
- Keep the upstream boundary in the service: validate raw โ normalize to the domain type โ return the output schema, and never fabricate a missing field โ an absent air time stays absent
