Trust breakdown (7 categories)
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (manage_owned_item). See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability87
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 6682 tokens (~39/item across 170 items; 12 tools + 158 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management33
- Stability observed for 10 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage94
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 79% of tool parameters carry a description.Partial
- Structured output schemas are declared (92% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 12 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 13 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities47
- Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28. See how to fix → Fail
- Supports UI / widget rendering.Pass
Install
How do I install the OffStereo MCP server?
OffStereo is a hosted endpoint at https://www.offstereo.com/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Tool
Tokens
create_playlist Create a playlist ~403
Create one playlist from a natural-language idea or explicit track list. Call exactly once per listener turn: do not inspect the result and make a corrective second call or stack another playlist card in the same response. previewOnly=true returns one authoritative playlist that can be heard before saving and needs no music-service connection. After explicit approval, previewOnly=false with the approved tracks and the same concise editorial name creates one private playlist in the listener's active music service. Pass service only when the listener explicitly names Spotify or Apple Music. requiredArtists carries every artist the listener named as required. allowSecondPlaylist is true only for an explicit request for a separate additional playlist. Sign-in recovery preserves the exact request and pendingActionId for a safe retry.
| Name | Type | Req | Description |
|---|---|---|---|
| allowSecondPlaylist | boolean | – | True only when the listener explicitly requests another separate playlist. Omit or pass false otherwise; this does not authorize a second create_playlist call in the same response. |
| count | number | – | Target song count for prompt-generated playlists (1-50, default 20). |
| name | string | – | A concise editorial playlist title. Omit it when the listener did not supply a title; OffStereo derives one from the prompt. |
| pendingActionId | string | – | Retry token returned by a prior auth_required result. |
| previewOnly | boolean | – | Resolve one unified playlist preview without saving or requiring a music-service connection. True when the listener asks to hear, inspect, or approve the songs before saving. |
| prompt | string | – | A conceptual playlist request, e.g. 'connect A Tribe Called Quest to Steely Dan'. |
| requiredArtists | array | – | Every artist the user explicitly requires, especially endpoints in a request such as 'from Minnie Riperton to Solange'. OffStereo validates these before creating anything. |
| service | string | – | Destination service. Pass only when the listener explicitly names one; otherwise OffStereo uses the active service on their account. |

discover Discover music ~328
Discover genre-aware new releases, strong public-archive matches, or popular OffStereo shows. Call exactly once per listener request: put every positive genre into the same genres array, use [] when none were requested, and avoid one call or card per genre. query carries the listener's full wording, exclusions, counts, and no-padding constraint. Results remain relevant rather than padding a requested genre or archive search with unrelated rows. Dated music-history requests use music_today and are not a discover mode. playableOnly limits results to music that plays in ChatGPT. allowBuild and allowSave preserve a read-only request. The result card already includes song playback; a separate one-song card is for an explicit request for a dedicated song card.
| Name | Type | Req | Description |
|---|---|---|---|
| allowBuild | boolean | – | False preserves an explicit request not to create or build a story. |
| allowSave | boolean | – | False preserves an explicit request not to create or save anything. |
| genres | array | yes | Every positively requested genre; [] when the request is not genre-filtered. Results do not pad with unrelated genres. |
| limit | number | – | Maximum total results (1-20). |
| perGenreLimit | number | – | Maximum results from each named genre for a balanced new-release request. |
| playableOnly | boolean | – | True limits results to music with audio that plays inside ChatGPT. |
| query | string | – | Archive query, or the listener's release-discovery wording when it contains genres, balance, count, or no-padding constraints. |
| type | string | yes | Discovery mode. search aliases archive; dated music-history requests use music_today. |

explore_lineage Explore sample lineage ~95

| Name | Type | Req | Description |
|---|---|---|---|

get_story_audio get story audio ~206
Get a finished OffStereo story as ONE downloadable MP3 — the narrated story, without the records. Use this on any surface where a player card cannot render: send it as a WhatsApp or Telegram voice note, attach it to an email, play it over a phone or speaker, or hand it to someone as a file. The URL is public and needs no OffStereo account, so it can be forwarded to anyone. It is narration only, which is why it is freely shareable — say so rather than promising the songs; the songs are at webUrl. Prefer this over reading a summary aloud in your own synthetic voice: this is the produced story, already voiced. Only finished shows have audio — poll get_show until status is ready.
| Name | Type | Req | Description |
|---|---|---|---|
| showId | string | – | The show id, from find_shows, make_playable or get_show. |
| slug | string | – | The show's slug, as find_shows returns it. Use either this or showId. |
No output schema declared.
No examples provided.
make_playable Play music or a story ~697
Create one playable OffStereo card for a direct standalone-song or narrated-story request. Discovery and Music Today already play their songs, so keep those results in their original card unless the listener asks for dedicated controls. experience=single_track returns exactly one recording with no narration or library save; pass artist plus track. experience=story progressively creates a sourced story; mode=fresh starts a new build. Pass artist plus album for an exact record and trackCount for an exact requested length. Spotify, Apple Music, and SoundCloud URLs are story seeds unless the listener requests only the recording. Playlist requests use create_playlist. existingSessionId opens a selected library story; get_session is reserved for card polling. The mounted card owns live progress and playback. Assistant prose should avoid restating transient stages such as building, recording, or still working because they become stale as the card updates, and should wait for Ready before stating final counts. A tool call opens the card without starting playback.
| Name | Type | Req | Description |
|---|---|---|---|
| album | string | – | Exact album or EP title, paired with artist when the listener names or shows a specific record. |
| artist | string | – | Exact artist, paired with track for a one-song card or with album for an album-focused story. |
| existingSessionId | string | – | The chosen library story id for opening through the canonical player contract; get_session remains application polling. |
| experience | string | – | single_track means one immediate song card with no narration or story creation; story means the full progressive narrated experience. |
| length | string | – | short fits an explicitly quick, brief, or concise narrated story and targets three narration-and-record chapters; standard keeps the full editorial arc. |
| mode | string | – | fresh starts an explicitly new story; auto may reuse an exact strong match. |
| personalization | string | – | library uses connected-listener taste as retrieval seeds; none is the default. |
| prompt | string | – | What the listening experience should explain. |
| resumeShowId | string | – | Rebuild an unfinished show in place, keeping its id and URL, instead of creating a second one. Pass the id of a show whose `retryable` is true. Rejected for a show that already finished or that belon… |
| sourceText | string | – | Source text or conversation context to adapt. |
| sourceUrl | string | – | An http(s) article or source URL to adapt. |
| title | string | – | Short canonical artist, track, album, or subject title for the card, especially useful for an identified image or a prompt that also contains workflow instructions. |
| track | string | – | Exact song title, paired with artist for reliable single_track matching. |
| trackCount | number | – | Exact number of songs requested for a narrated story (2-12). Use 1 with experience=single_track. |
| tracks | array | – | Optional: exact records the story should always include as playable tracks — e.g. every song a paired video names. They are pinned into the show in this order and curation fills the remaining slots u… |

manage_owned_item Manage my library ~157
Manage the signed-in listener's own OffStereo stories or service playlists. Removing an OffStereo story is a recoverable archive operation, and restore brings it back. Removing an owned Spotify playlist means remove from library because Spotify does not permanently delete playlists; the operation follows an explicit confirmation turn. Apple Music's public API does not expose playlist deletion, so that case returns an honest unsupported handoff. confirm=true records explicit confirmation of the named item and operation.
| Name | Type | Req | Description |
|---|---|---|---|
| action | string | yes | – |
| confirm | boolean | – | Records the listener's explicit confirmation of the named destructive operation. |
| id | string | yes | OffStereo session id or saved playlist id. |

music_today Music today ~285
Call exactly once for a 'today in music' or dated music-history request. One response already combines album anniversaries, artist birthdays and memorials, current releases, current US song-chart context, and related playable OffStereo stories; use that one combined call rather than separate history, releases, charts, or shows calls. dateMode=today uses the listener's current day and omits date; dateMode=explicit pairs with a named YYYY-MM-DD date. limit is the maximum total across the combined response, playableOnly limits rows to music that plays in ChatGPT, and allowBuild=false plus allowSave=false preserves a read-only request. This is the only dated-music tool in the current schema.
| Name | Type | Req | Description |
|---|---|---|---|
| allowBuild | boolean | – | False preserves an explicit request not to create or build a story. |
| allowSave | boolean | – | False preserves an explicit request not to create or save anything. |
| date | string | – | ISO date YYYY-MM-DD for dateMode=explicit; absent for dateMode=today. |
| dateMode | string | yes | today represents the listener's current day; explicit represents one named calendar date. |
| limit | number | – | Maximum total results across the already-combined response (1-20, default 8). Honor an explicit result count. |

prepare_episode Prepare a Spotify episode ~132
Prepare one finished OffStereo story to become a private Spotify episode after the listener explicitly asks. OffStereo packages its completed intro, ordered narration, sign-off, branded title, show notes, OffStereo cover, chapters, and song timeline, then returns an honest handoff: the episode is not in Spotify until the listener finishes with Spotify's Save to Spotify helper on their own computer. Use the active or selected story's sessionId. This is for a narrated story, not a playlist or an unfinished build.

save_session Save the story playlist ~98
Explicitly save the matched music from one listening session as a private playlist in the listener's active music service. Pass service only when the listener explicitly names Spotify or Apple Music. Unmatched songs are excluded and reported. If sign-in is needed, OffStereo preserves the request for one safe retry.

steer_session Steer the listening session ~306
Control and contextual follow-ups for the active player: pause, resume, skip, play the next song, append one exact next song, adjust the music level, explain why a song is present, open an explicitly requested documented sample lineage, or return to the story. The result updates the mounted card in place. For an AI-DJ transition to a newly chosen record, pass queueTrack with exact artist and title; OffStereo resolves it and appends it to this same widget so the current song can finish and auto-advance. Keeping the transition in this queue avoids a second make_playable call. Use instruction='Queue this as the next song without interrupting the current song' to queue ahead, or 'Play this next now' to append and immediately advance. A why-this-song question preserves the queue. sessionId identifies the active session, and activeItemId plus positionMs preserve exact continuity when the card supplies them.
