osc-bridge MCP Server

Find which devices are connected to the user's machine through a relay: sends the MIDI Identity Request (F0 7E 7F 06 01 F7, changes nothing on the device) to every output and matches the answers — manufacturer, model, firmware version — against the drivers' identity blocks. With maker_requests, also sends the makers' own identity requests the drivers name (they change nothing either, but the relay asks the user to accept them, once per output: tell the user first), which recognise devices that ignore the universal one. Returns the best driver ids (recognised_by and firmware when an identity block recognised the device) and identity_hex to pass to report_result. A device that does not answer is found by its knobs with listen_ms (by_controls), or by what people confirmed of its port name (learned); when several remain, ask names the control to have the user turn next (expect: what each candidate would send), then call again with listen_ms.

Listen to what the user's hardware sends through a relay for a few seconds: notes, CC, NRPN, SysEx, decoded. With a device, each CC or NRPN that moved is matched to the driver's OSC addresses — ask the user to move one control on the device while listening to learn which address it is, or to check that the driver's map is right (then record what you saw with report_mapping, so the catalogue learns it).

Play or set something on the user's hardware through a relay: give a driver (id or slug) and one of its OSC addresses from list_routes with its arguments (e.g. address '/filter/cutoff', args [64]; '/note/on', args [60, 100]) — the server turns it into the right CC, NRPN, note or SysEx message. Or give raw MIDI bytes as hex. Values are the device's own numbers, clamped to the parameter's range. Any SysEx but the Identity Request (patch dumps, stores, settings, preset restores) may overwrite the device's memory: the relay asks the user to accept it first and this call waits for the answer (up to 2 minutes), so tell the user what you are about to send.

Check a relay: the user opened https://synthhub.roomi-fields.com/connect/ (or ran osc-bridge connect) and gave you its pairing code. Returns the MIDI output and input ports of their machine, and devices: the driver the user confirmed for each port on the page (use it directly, no detection needed). Nothing is sent to the hardware.

One shared preset in full: its content (SysEx hex, settings by driver address, MIDI file), description and playing tips, versions with their change notes, what it was derived from and its derivatives (remixes), comments, preview URLs, author, licence and attribution line, trust and counts. Load it with load_preset; credit it as the attribution line says when you publish something made from it.

Collections of shared presets, public, made by one account (e.g. 'Dark basses for minilogue'). action: create (name, description), rename (collection, name, description), add or remove (collection, id), delete (collection), get (collection: its presets), list (this account's collections, or author: someone's).

Publish a new version of a preset this account shared: new content (hex, file, settings or midi_file) makes a new version, kept with a change note — earlier versions stay available; the description fields alone change it in place. Someone else's preset: share yours with derived_from instead.

Teach the catalogue which MIDI message a control really sends: after the user moved one control on the device (see relay_listen), give the driver address it is (from list_routes) — or, for a control the driver lacks, its panel label — and the CC, NRPN or note it sent, with the firmware and the device's Identity Reply when you have them. When several accounts observe the same thing on one firmware the mapping is learned; get_trust shows learned mappings and where they differ from the driver.

Tell SynthHub how a shared preset behaved once loaded on a real device: 'works' (it loaded and sounds as described), 'fails' (refused, wrong sound), or 'factory' (it is a factory preset or someone else's sound: presets that several users flag are hidden until reviewed). Give the firmware.

Tell the catalogue how a driver behaved on a real device, after testing it: 'works', 'fails' or 'partial', for the whole driver or one OSC address (from list_routes). Give the firmware version, and the device's reply to the MIDI Identity Request (F0 7E 7F 06 01 F7) as identity_hex when you can: trust is counted per firmware, so a failure on another firmware does not count against the driver, and a report of unknown firmware cannot be placed. Several accounts that agree on one firmware mark the driver usage-verified there; a report that several others contradict is rolled back and puts its account under review. Report only what was actually tested.

Contribute a driver for a device the catalogue lacks (or a better one): the full driver file as a JSON object, in the osc-bridge device schema (device.name, device.vendor, device.osc_prefix, and cc_params / params / commands / triggers — see https://synthhub.roomi-fields.com/DEVICE_JSON_SCHEMA/). It is checked, then merged into the SynthHub catalogue by the merge job if it parses, lints and passes the tests, as its own file of source 'agent-contributed'. Say where the data comes from (manual page, tested on the device).

Contribute a corrected variant of a driver from what the catalogue learned: where learned mappings (get_trust → mappings, differs: true) disagree with the driver on one firmware, builds a copy of the driver with the learned CC / NRPN numbers, as a new file for that firmware, and queues it for the merge job.

Claim presets SynthHub imported from another site (their page says 'imported', with the author's name and page there) when the user is that author: give the id of one of them; the server answers with a code for the user to add to their author page at that site (profile or bio). Once it is there, call again with verify: true: every preset imported from that author becomes the user's, to edit or withdraw.

Comment on a shared preset — how it sounds, how you used it, what you changed — optionally attaching your remix (a preset you shared with derived_from). Comments are public at once. Also: remove one of this account's comments (remove), or flag someone else's as abusive or off-topic (flag); comments several accounts flag are hidden until reviewed.

Where a contribution stands: pending (waiting for the merge job), merged (with its pull request), rejected (with the reason), or held (its account is under review).

Fetch the markdown companion documentation for one device, if present. The slug is the device's OSC prefix without the leading slash (e.g. 'ableton' for /ableton).

Find device drivers in the catalogue of synths, drum machines, controllers and DAWs. Without arguments it lists them all; `query` keeps drivers whose vendor, name or slug contain every word (e.g. 'korg minilogue'). Returns name, vendor, OSC prefix (slug), kind, source tier and firmware version when the source states one. Pass the slug to list_routes for the full CC/NRPN/SysEx map.

Write one driver in a format other tools read: 'oscquery' gives its OSC namespace as OSCQuery JSON (every route with type tags, ranges and access, for OSC controllers and browsers); 'midnam' gives its MIDI names as a MIDI Name Document (controllers incl. NRPN/RPN, named values, drum notes per channel, for DAWs such as Ardour or Logic). Both carry the credit and licence of the driver's sources. The document is the text content; an OSCQuery namespace is large (every address, each CC 0-127 included).

Follow an author of shared presets (by pseudonym), or stop (on: false); with author alone and on omitted, shows their page: profile, presets, followers. Without author, lists the newest presets of the authors this account follows.

Link this account to the user's SynthHub account on the site: returns a one-time address (valid 15 minutes) for the user to open and sign in (passkey, e-mail, Google or Discord). Afterwards what this account shared appears under their profile, and they manage it — and their stars, collections, comments — from the site. Offer it when the user wants to see or manage what you shared for them.

Load a shared preset (find_presets, get_preset) into the user's device through a relay: its settings are sent through the driver, its patch data as SysEx — which replaces the sound the device holds, so the relay asks the user to accept it and this call waits for the answer (up to 2 minutes): tell the user first. Afterwards, tell SynthHub how it went with report_preset.

Search what SynthHub users shared (CC BY-SA 4.0): sounds, sequences, kits, projects, banks, MIDI clips. Filter by device, kind, category, genre, tag, author (pseudonym) or words; sort by newest, most stars, most loaded into a device or most trusted (confirmed on real devices). Returns, per preset, its id, name, kind, device, description, author, version, whether it has device data, settings, a MIDI file or an audio preview (URL), and its counts. Get one with get_preset.

Set the public profile shown on this account's author page and with its shared presets and comments, instead of its pseudonym alone: display name, link (https), a few words, the presets put first, where they are, more links, their instruments and a README. A field left out stays as it is; an empty one is cleared. Ask the user what they want shown; all of it is public.

Return the OSC routes a device exposes: declarative commands (OSC paths it accepts), cc/nrpn params, sysex params, named note triggers (drum sounds), and reply patterns. Use this to discover what a device can do.

Share something the user made on a device with every SynthHub user, under CC BY-SA 4.0: a sound, a sequence or pattern, a kit, a project, a bank of their own sounds, or a MIDI clip any device can play. Its content: the device's own data (SysEx, e.g. from backup_presets), settings by driver address (from list_routes, e.g. {'/filter/cutoff': [90]}, which also works for devices without dumps), and/or a standard MIDI file. Only what the user made: never factory presets, nor sounds or sequences bought or downloaded from others — set own_sound only after asking the user. Made from someone else's shared preset? Pass derived_from: it credits them, as the licence requires. Describe it well (category, genres, tags, tempo, key, tips): that is how people find it. The same content shared twice returns the existing id; the author publishes new versions with update_preset and can withdraw it (withdraw_preset). Through a relay, the device data can be captured from the device itself: pass code and start the dump from the device's menu during the call, or give request_hex (the device's dump-request message, which the user accepts at the relay). An audio preview is added by its author with PUT /u/<account>/v1/presets/<id>/audio (MP3, Ogg, M4A or WebM, 1 MB at most).

Star a shared preset for this account, as on GitHub (on: false takes the star back). Without id, lists the presets this account starred.

Take the sound the user's synth is playing — or one of its stored programs — straight from the synth through a relay, with its name. The synth is found among those SynthHub's librarian can talk to (the KnobKraft Orm adaptations, about 90 synths) by the identity and detect messages, then asked for its sound. The person accepts each step at the relay (finding the synth, asking it): tell them first. To share it: ask the user whether they made this sound themselves (never a factory preset, nor one bought or downloaded), then call share_preset with the device, name, hex, librarian and firmware returned here, and own_sound: true. When several synths answer, or none did, call again with port.

How far a driver has been confirmed by people who used it, per firmware: status (unreported, unconfirmed, usage-verified, firmware-dependent, failing, disputed), how many users report it works / fails / partly works, each firmware's own status, the device identities seen for each firmware, and the same per OSC address. needs_firmware: true means reports disagree and some have no firmware — identify the device before reporting (see learn). Check it before relying on a driver, together with its source_tier.

Withdraw a preset this account shared: it is no longer listed nor served. Copies others already made stay under CC BY-SA.
