dawmcp AGENTS.md

Project instructions for dawmcp, a Rust workspace that lets an AI client control a running digital audio workstation (DAW) such as REAPER or Audacity.

In plain words
What is it for?
Use it when developing, debugging, or extending dawmcp and its DAW adapters.
Why use it?
It gives an agent the project’s purpose, architecture, current status, and important files so work can continue with the right context.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dawmcp AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AGENTS.md

Project brief for picking up work on dawmcp in a new conversation.

What this is

An MCP server (Rust, Cargo workspace) that lets an LLM client drive a live, running DAW instance in real time: transport control, tracks, FX, and rendering, through a DAW-agnostic tool surface with a per-DAW adapter behind it. REAPER is the first adapter, with tool parity for transport, tracks, FX, MIDI, media items, markers, view/zoom, rendering, project state, native UI action control, compose_and_render, and a run_reascript escape hatch. Audacity is the second adapter, with transport/track/render parity (see "Current status" for what's still unsupported there). dawmcp-server selects which adapter to serve tools over via --daw=reaper|audacity (default reaper); .mcp.json registers both as separate MCP server entries so Claude can connect to either. See README.md for user-facing setup/usage and docs/ARCHITECTURE.md for the full design writeup (the latter still describes the REAPER bridge protocol specifically; it predates the multi-DAW trait split and hasn't been fully updated for it yet).

Current status

Rust rewrite complete for REAPER: full tool parity with the original Python implementation, verified against a real running REAPER instance (live --install-bridge run, live tool round-trip over stdio). The Python implementation (reaper-mcp) has been removed from the repo; git log has its history if needed.

dawmcp-audacity implements DawBackend over mod-script-pipe, with every command name and parameter key verified against Audacity's own source (audacity/audacity on GitHub - see dawmcp-audacity/src/backend.rs's doc comment for exact file/line references), not assumed from memory. Working: transport (play/stop/pause/record), track add/remove/rename/list, per-track volume/pan/mute/solo, and render/export (Export2). Deliberately Unsupported because the underlying concept doesn't map cleanly (not because it's unverified): transport_seek/transport_set_tempo/ transport_get_state (no verified playhead/tempo query), fx_* (Audacity has no persistent per-track FX chain like REAPER's), track_set_color (Audacity's colour is a small preset enum, not arbitrary RGB). discovery.rs finds Audacity installs/processes on Windows/macOS/Linux, same shape as the REAPER adapter's discovery, verified live on this machine.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
