v0.7.0

Distribution update (2026-10-31, updated 2026-11-03): the Python wheel and MCP bundle have been withdrawn because they included a private MIDI corpus. The MIDI corpus is not part of the public distribution. Extension and MIDI Remote Script downloads remain available. A Python wheel and MCP bundle without the corpus are available in the v0.8.1-rc1 pre-release.

# Release Notes

v0.7.0

v0.7.0 publishes the expanded 97-tool Ableton MCP Server surface. It introduces
plan_user_journey, an updated retrieval seed v3 with per-collection SD3 and General MIDI
articulation maps, a high-speed UDP realtime control channel, and deterministic
polyrhythm transformations.

Highlights

  • 97 catalogued MCP tools: 75 TCP, 3 WebSocket, 5 composed, and 14 local or
    headless routes.
  • New plan_user_journey tool providing structured four-stage planning (discover,
    await confirmation, apply, verify).
  • Dedicated UDP realtime control channel on port 9890 (contracts.REALTIME_UDP_PORT)
    with guarded message draining.
  • Regenerated retrieval seed v3 with 4,000 curated grooves across 266 collections,
    Superior Drummer 3 and General MIDI articulation mappings, 85.8% genre coverage,
    and tempo/bpm indexing.
  • Polyrhythm transformation axis support for deterministic groove generation.
  • Loopback-only TCP (127.0.0.1:9888) and WebSocket (127.0.0.1:9889) bridges.
  • Version-aware release artifacts with SHA-256 checksums and source-commit provenance.

Artifacts

  • ableton_mcp_server-0.7.0-py3-none-any.whl
  • AbletonMCPServer_RemoteScript-0.7.0.zip
  • AbletonMCPServer-Extension-0.7.0.ablx
  • SHA256SUMS
  • ableton-mcp-server-0.7.0.mcpb

Installation

Install the wheel, extract the Remote Script into Ableton's User Library, and
install the .ablx Extension. Restart Ableton Live, select
AbletonMCPServer as a Control Surface, then run:

.\.venv-win\Scripts\ableton-mcp.exe install-status --json
.\.venv-win\Scripts\ableton-mcp.exe doctor --json

MCP Bundle

The MCPB package installs the stdio server in clients supporting MCPB 0.4 and
the UV runtime on Windows. In Claude Desktop, use Settings > Extensions >
Advanced settings > Install Extension and select the .mcpb file. The client
manages Python and locked dependencies. Installation and read-only Live
connectivity were verified on Windows with Live 12 Beta.

The Remote Script and Extension still require installation in Ableton Live for
the 83 tools that may use Live. The 14 local/headless tools work without Live.

Checksums and provenance

The wheel and Remote Script ZIP were rebuilt from the existing v0.7.0 tag
(fb14fea1d71d3c45630b89a5e841a85d8b9718b0) on 2026-10-11. The original wheel and ZIP listed in the
repository's releases/v0.7.0/SHA256SUMS were not preserved; rebuilt files have
new checksums. The ABLX is the original v0.7.0 build.

The MCPB was packaged from commit d7ecfdf93bf734533752358dc09d9a8bd329c693. Its server source is
identical to v0.7.0; packaging adds the MCPB manifest, launcher and dependency
lock. Use the SHA256SUMS attached to this release for the downloadable assets.
