What is mixx-dj-mcp AGENTS.md?

A project instruction file for mixx-dj-mcp, a server that lets coding agents control the Mixxx DJ application through OSC, a message protocol for sending control data. It records ports, commands, important files, and development recipes.

Use it to start the server and web app, configure Mixxx, run tests and linting, build the native package, or locate deck, library, and effects controls.

It gives agents the connection details and code map needed to run, test, and change the DJ-control system correctly.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01048	$0.01048
Opus 5.5	$0.00419	$0.00419
Sonnet 5.5	$0.00210	$0.00210
Haiku 4.5	$0.00105	$0.00105

Security

Grade A, and why

mixx-dj-mcp 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 2mo ago.

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.

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.
