Convert speech to text using microphone recording or existing audio file
AI agents call speech_to_text to retrieve information from A-Modular-Kingdom without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Speech-to-text transcription is a read operation that captures or processes audio input and outputs text. It does not create, modify, delete, or execute external operations; it merely transforms one data format into another. The most severe concurrent tool on the server (code_execute, delete_memory) does not elevate this tool's classification. Confidence is high because the description is clear and unambiguous.
From the tool's definition Tool name and description indicate it 'Convert[s] speech to text' from 'microphone recording or existing audio file' — a data retrieval/transcription operation with no side effects on system state.
Documented attack patterns abuse exactly the kind of access speech_to_text gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and A-Modular-Kingdom, and nothing reaches the server without passing your rules. This is the rule we recommend for speech_to_text:
{
"version": "1",
"default": "deny",
"tools": {
"speech_to_text": {}
}
}speech_to_text is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Convert speech to text using microphone recording or existing audio file. It is categorised as a Read tool in the A-Modular-Kingdom MCP Server, which means it retrieves data without modifying state.
Register the A-Modular-Kingdom MCP server in PolicyLayer and add a rule for speech_to_text: 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 A-Modular-Kingdom. Nothing to install.
speech_to_text 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 speech_to_text 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 speech_to_text. 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.
speech_to_text is provided by the A-Modular-Kingdom MCP server (masihmoafi/a-modular-kingdom). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from A-Modular-Kingdom, 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.
