Bluecolumn Memory tools (14)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • audio_ingest

    NEW (Audio Intelligence): Ingest audio (calls, voice notes, podcasts, music) and extract semantic memory using the audio-intelligence layer. Requires BLUECOLUMN_API_URL to point at the BlueColumn API.

  • audio_recall

    NEW (Audio Intelligence): Search audio memories and get audio-backed citations.

  • call_complete

    NEW (Audio Intelligence): Store what changed after a call ends.

  • call_prepare

    NEW (Audio Intelligence): Get memory context before a voice call starts.

  • music_analyze

    NEW (Audio Intelligence): Extract tempo, structure, instrumentation, mood from music.

  • music_recall

    NEW (Music Memory): Search stored musical content with musical filters. Returns AI-synthesized answers with citations. Filter by instrument, techniques, or style — e.g. 'show me every take with barre chord issues' or 'what did we practice in E minor last month'.

  • music_remember

    NEW (Music Memory): Store a musical recording, practice session, or lesson with rich musical context — instrument, key, tempo, technique tags, chord progression, and free-form notes — into BlueColumn. Audio is transcribed; the structured context is embedded alongside so a coach/teacher agent can recall it with full musical understanding. Works today via the core memory API; dedicated music endpoin

  • namespace

    Get the BlueColumn namespace this MCP server is configured to write/read (default: nl).

  • note

    Store a lightweight agent observation as a searchable vector. Use when the agent wants to save a quick preference, decision, or observation without needing full document processing. Faster than remember for short notes.

  • recall

    Query BlueColumn memory using natural language. Returns an AI-synthesized answer with source citations. Use when the agent needs to retrieve past information, answer questions about stored content, or get context from previous sessions.

  • remember

    Store text, a document URL, or audio URL into BlueColumn persistent memory. Returns a summary, action items, and key topics automatically extracted by AI. Use when the user or agent wants to save information for future recall.

  • sound_analyze

    NEW (Audio Intelligence): Detect and index non-speech audio events.

  • streaming_audio_ingest

    Ingest an edge-device audio chunk (car, doorbell, wearable) into per-device streaming memory. Whisper large-v3 transcription, entity + intent extraction, idempotent retries.

  • streaming_audio_recall

    Recall over streamed device-audio memory for a specific device. Returns transcribed segments and session summaries ranked by relevance.

Install Bluecolumn Memory in Claude Code, Cursor or VS Code

Runs npx -y bluecolumn-mcp on your machine. Read the scan report first; the gateway never runs local packages.

Music Memory example

Store a practice session:

music_remember {
  "audio_url": "https://example.com/take3.mp3",
  "title": "Week 3 practice — barre chords, Sep 7",
  "instrument": "guitar",
  "musical_key": "E minor",
  "tempo_bpm": 92,
  "technique_tags": ["barre-chords", "hammer-on"],
  "style_tags": ["blues"],
  "chord_progression": ["Em", "Am", "B7"],
  "notes": "F-shape barre still buzzy on the B string; Fmaj7 subst worked well"
}

Then recall it musically:

music_recall { "q": "which takes had barre chord issues?", "instrument": "guitar" }
