api record

The PICA directory: search songs and their rights. Every listed song was put there by the people who own it, with writers, publishers, identifiers (ISWC, ISRC, IPI), how confirmed each credit is, and a way to ask the owner about licensing. No account or sign-in is needed.

  • directory_list_people open 1h ago

    Use when the user asks: 'list creators in PICA', 'people starting with B', 'browse the people directory'. Browse and filter creators in the PICA public directory. Filter by free-text (q), ISNI, IPI, or starting letter (A–Z, or '#' for numeric). Returns paginated results. Each result carries global_creator_id, the ID directory_lookup_person takes. → then: directory_lookup_person (identifiers, roles, listed-work count and collaborators for one creator)

  • directory_list_works open 1h ago

    Use when the user asks: 'list works in PICA', 'works starting with B', 'find works by publisher X', 'browse the catalog', 'a song about love', 'songs about X'. For a theme or subject, search its plain word in q ('love', 'home', 'summer'): titles carry the theme. Start here before any mood or sound search, which only narrows. Browse and filter musical works their owners have listed in the PICA public directory. Filter by free-text (q), ISWC, ISRC, publisher, label, or starting letter (A–Z, or '#' for numeric). Sort by title (default) or recent. Returns paginated results. Each work carries ai_origin: whether the OWNER declared it human-made, AI-assisted or AI-generated (or 'not stated' — never assume human-made), with ACRCloud's AI detection beside it. Set human_made_only to keep only works the owner declared human-made that ACRCloud does not call likely AI. → then: directory_lookup_work (full details with credits and audio)

  • directory_lookup_work unknown never probed

    Use when the user asks: 'what's the ISWC for X?', 'who wrote X?', 'tell me about song X', 'is this song registered?'. Get the details of a single listed work by ISWC or work UUID. Returns the credits, one per person with each role marked confirmed or not confirmed by that person, and the person's IPI; each writer's share of the work, only when the owner chose to show shares AND that writer confirmed it themselves (with how many writers have); the recordings' ISRCs, audio analysis (BPM, key, energy) when the audio has been analysed, streaming links (Spotify, Apple Music, YouTube), AI origin (what the owner declared, with ACRCloud's detection beside it), the work's PICA score, and whether the owner is taking licensing enquiries, as a markdown summary. Fields with no data are omitted. → then: directory_lookup_person (a credited writer, by the credit's global_creator_id or IPI), directory_search_recordings (find similar tracks by audio)

  • directory_lookup_person unknown never probed

    Use when the user asks: 'lookup IPI 12345', 'lookup ISNI X', 'find creator by MusicBrainz ID'. Also use it for the profile of a creator already found with directory_list_people or directory_search. Looks up ONE creator in the PICA public directory by an identifier: global_creator_id (UUID, from directory_list_people or directory_search), ISNI, IPI number, or MusicBrainz ID. It does not accept a name: to find a creator by name, or to choose between several people with the same name, use directory_list_people (q) or directory_search first. Returns the creator's name, identifiers (IPI, ISNI, MusicBrainz), roles, the number of their works listed in the directory, their PICA profile grade, and up to five collaborators on those listed works. It does not list the works themselves: use directory_list_works or directory_search with the creator's name for those. An unknown identifier returns not found. → then: directory_list_works (their listed works, by name)

  • directory_search unknown never probed

    Use when the user asks: 'find me X', 'who or what is X?', 'find any record of X', 'a song about X'. Use when the entity type is not yet known. Convenience fan-out across works and creators — runs list_works and list_people with the same query and returns the union. No cross-type ranking; prefer list_works or list_people when the entity type is known. → then: directory_lookup_work (work details), directory_lookup_person (creator details, by the result's global_creator_id)

  • directory_search_recordings unknown never probed

    Use when the user asks: 'find upbeat tracks around 120 BPM', 'find instrumental tracks in C minor', 'find energetic music for sync', 'tracks at X BPM in [key]'. AUDIO-FEATURE search only — for name- or title-shaped queries use directory_lookup_work, directory_lookup_isrc, or directory_list_people, NOT this tool. Not for a theme or subject ('a song about love'): search that in directory_list_works q first, then narrow here. Few recordings carry a mood yet, so an empty mood search does not mean the directory has no such song. Find tracks by BPM, key, energy, danceability, duration, mood, and more. The measured filters (BPM, key, energy, …) match analysed audio only; a mood search also returns works whose owner set the mood, marked mood_note "mood set by the owner, not analysed" — say so when you present them. Only returns recordings of works listed on the directory by their owner or a confirmed writer. → then: directory_lookup_work (credits and licensing details for a matched track)

Any other word is refused. A mood matches analysed recordings, and also listed songs whose owner set that mood on audio that is not analysed: those carry mood_note \"mood set by the owner, not analysed\" and no measured values.

  • directory_skill_list unknown never probed

Returns the full methodology body for one directory skill — markdown with step-by-step instructions and tool chains. Call directory_skill_list first to see available skill names, then directory_skill_get to load one. Read once at the start of the workflow; do not re-fetch on every step. → then: directory_search (run the loaded methodology against the catalogue)

NOT for catalogue content searches (use directory_search / directory_list_works / directory_chain for those). Returns { package, current_version, releases: [{ version, date, sections, markdown }], resource_uri }.

  • directory_send_licensing_enquiry unknown never probed

    Use when the user asks: 'ask the owner if I can license this', 'send a licensing enquiry for X', 'contact the rights holder about using this song'. Side effect: this SENDS AN EMAIL. It records a licensing enquiry for a work listed in the public directory and emails it to the work's owner, who can reply to the user by email (the user's address is shared with them); a confirmation email to the user is usually sent but not guaranteed. Nothing is agreed or priced: it only opens the conversation. This is the ONLY way to reach a listed work's owner: PICA never shares the owner's email address, so never draft the enquiry as an email for the user to send, and never guess an address. Sending through this tool is also what records the enquiry for the owner. ONLY call after the user has explicitly asked to send it and has given their own name, email and a description of the project. Never invent these, and never send on their behalf without asking. Get work_id from directory_lookup_work, directory_list_works or directory_chain. A 403 means the owner is not taking enquiries; a 404 means the work is not publicly listed; an unknown outcome means it may already have been sent, so never resend without asking. MORE WORKS FROM THE SAME OWNER: before sending, you may call directory_similar_from_owner and offer the user the owner's similar works. Put a work in also_work_ids ONLY if the user explicitly said yes to adding that work; never add works on your own judgement. All works go to the one owner in one enquiry (at most 10 in all); a work from another owner is refused. NOT FOR: looking up who owns a work (use directory_lookup_work). → first: directory_similar_from_owner (optional, to offer more of the owner's works) → then: directory_lookup_work (the work page and credits, to share with the user)

  • directory_chain unknown 1h ago

    Use when the user asks: 'show me the rights chain for X', 'give me everything on this song', 'what's the full picture for X?', 'trace the chain from this writer to that work'. Graph lookup — resolves a query, ISWC, or ISRC to its full rights chain in one call. Each result bundles the work, its writers and publishers (names + roles, no IPIs or splits), the linked recording (ISRC, DSP presence, duration), and audio characteristics (BPM, key, energy). Prefer over stitching list_works + lookup_work + lookup_person when you want the whole graph around a track in a single round-trip. Supports audio-only queries (min_bpm, key, mood, etc.) when you don't have a text query. Work results carry programmable_since (every owner confirmed a locked split) and ready_to_license (composition and a master confirmed, with audio, ISRC and ISWC); filter to either with programmable_only / ready_to_license. → then: directory_lookup_work (deeper work detail), directory_list_people (research a named writer by name)

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 2a4aa743597f34a4.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/2a4aa743597f34a4/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
