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 | $0.04648 | $0.04648 |
| Opus 5 | $0.02324 | $0.02324 |
| Sonnet 5 | $0.00930 | $0.00930 |
| Haiku 4.5 | $0.00465 | $0.00465 |
Grade A, and why
fl-studio-mcp 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 9d 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.

FL Studio Direct Integration - Documentation
Platform Support
⚠️ macOS Primary, Windows Secondary - This project primarily supports macOS with full auto-trigger functionality. Windows support is partially implemented but may require additional configuration.
Overview
This system allows Claude to interact with FL Studio's piano roll through direct file-based communication. It provides seamless integration between Claude's AI capabilities and FL Studio's music production environment with built-in timing delays to ensure reliable operation.
Installation and Setup
1. Install MCP Server for Claude
./install_mcp_for_claude.sh
This registers the MCP server with Claude Code. The server is named fl-studio-mcp.
2. Usage Workflow
For each session:
- Open FL Studio and open a piano roll
- Run ComposeWithLLM once (Tools → Scripting → ComposeWithLLM) to initialize
- Start Claude - the trigger mechanism is built into the MCP server
- No need to run separate scripts - everything is handled automatically!
Note: Claude Code needs Accessibility permissions (System Settings → Privacy & Security → Accessibility) to send keystrokes to FL Studio.
Getting Started (For AI Assistants)
If you're an LLM helping the user with this system, here's what you need to know:
1. Check Available Tools
First, verify you have access to these MCP tools (they'll have the mcp__fl_studio_mcp__ prefix):
mcp__fl_studio_mcp__get_piano_roll_state- Read the piano rollmcp__fl_studio_mcp__send_notes- Add or replace notes (including chords)mcp__fl_studio_mcp__delete_notes- Remove specific notesmcp__fl_studio_mcp__clear_piano_roll- Clear all notesmcp__fl_studio_mcp__clear_queue- Clear pending requests
If these aren't available, the MCP server needs to be started or reconnected. The server is registered as fl-studio-mcp in Claude Code.
2. Auto-Trigger System
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.

fl-studio-mcp CLAUDE.md is an instructions file published in the GitHub repository calvinw/fl-studio-mcp (37 stars, last pushed 8mo ago), licensed MIT. It adds 4,648 tokens to every session, about $0.0232 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
