AI agents invoke sstv_encode_text to trigger actions in Sensory. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool actively processes input text and generates audio output (base64-encoded WAV file), triggering an encoding/signal-generation operation. It goes beyond simply reading or writing stored data — it executes an audio synthesis pipeline. Misuse could involve encoding malicious or covert signals into audio streams for transmission over off-grid radio networks, hence medium severity.
From the tool's definition Encode text to SSTV audio (Robot36/Martin/Scottie). Returns base64 WAV.
Attacks that exploit this kind of access
Encode text to SSTV audio (Robot36/Martin/Scottie). Returns base64 WAV. Multi-modal bridge for small LLMs!. It is categorised as a Execute tool in the Sensory MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Sensory MCP server in PolicyLayer and add a rule for sstv_encode_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 Sensory. Nothing to install.
sstv_encode_text is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the sstv_encode_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 sstv_encode_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.
sstv_encode_text is provided by the Sensory MCP server (jaspertvdm/mcp-server-sensory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
sstv_encode_text is one line of Sensory's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
