Get whether a step is active in the step sequencer.
AI agents call fl_get_grid_bit to retrieve information from FL Studio MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query of the step sequencer state. It retrieves data about whether a specific step is active, with no side effects, no execution of external code, and no modifications to the FL Studio project. The sibling tools show this server includes destructive operations (fl_delete_notes, fl_clear_piano_roll) and write operations (fl_arm_track), but this particular tool is purely informational.
From the tool's definition Tool name 'fl_get_grid_bit' and description 'Get whether a step is active in the step sequencer' indicate a query operation that retrieves state information without modifying, executing, or destroying anything.

PolicyLayer is an MCP gateway — it sits between your AI agents and FL Studio MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for fl_get_grid_bit:
{
"version": "1",
"default": "deny",
"tools": {
"fl_get_grid_bit": {}
}
}fl_get_grid_bit is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get whether a step is active in the step sequencer. It is categorised as a Read tool in the FL Studio MCP Server MCP Server, which means it retrieves data without modifying state.
Register the FL Studio MCP Server MCP server in PolicyLayer and add a rule for fl_get_grid_bit: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches FL Studio MCP Server. Nothing to install.
fl_get_grid_bit is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the fl_get_grid_bit rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for fl_get_grid_bit. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
fl_get_grid_bit is provided by the FL Studio MCP Server MCP server (karl-andres/fl-studio-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from FL Studio MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
