dawmcp CLAUDE.md

Project instructions for dawmcp, a Rust server that connects coding agents to REAPER, a music-production application. They describe the build and test process and note that some checks require a running REAPER instance.

In plain words
What is it for?
Use them when building or testing dawmcp, checking its status, reviewing CI, or working with the REAPER bridge.
Why use it?
They explain the expected server behavior and the limits of automated testing, reducing misleading diagnoses.

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 CLAUDE.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.

See AGENTS.md for the full project brief (architecture, key files, setup/test loop, past decisions, conventions, and open next steps). Read that file first when picking up work here in a new conversation.

Claude Code specific notes

  • CI runs cargo build --workspace and cargo test --workspace on push/PR to main via .github/workflows/ci.yml (windows-latest, matching the project's primary target). Check gh pr checks before merging if CI has had time to run; cargo test --workspace locally is still the faster loop while iterating.
  • The MCP server itself (dawmcp, cargo run -p dawmcp-server) is stdio-based and blocks waiting for a client - that's expected behavior, not a hang, when run directly rather than through a client like Claude Code/Desktop.
  • Live end-to-end testing requires a real running REAPER instance with lua/reaper_bridge.lua loaded via REAPER's Actions list; this can't be verified from an automated test run alone. dawmcp --status is the fastest way to check reachability without needing an MCP client.
  • The project was originally a Python implementation (reaper-mcp, REAPER-only); it was rewritten in Rust and generalized to multiple DAWs (dawmcp) - see AGENTS.md's "Decisions worth knowing" for why.
Changes

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.
