classify_sleep_cause
AI agents call classify_sleep_cause to retrieve information from Decoder 3am without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to perform symptom analysis and classification against a fixed framework (The Longevity Vault's 5-cause framework). This is a Read operation: it processes input, queries or matches against internal classifications, and returns information.

classify_sleep_cause. It is categorised as a Read tool in the Decoder 3am MCP Server, which means it retrieves data without modifying state.
Register the Decoder 3am MCP server in PolicyLayer and add a rule for classify_sleep_cause: 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 Decoder 3am. Nothing to install.
classify_sleep_cause 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 classify_sleep_cause 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 classify_sleep_cause. 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.
classify_sleep_cause is provided by the Decoder 3am MCP server (thelongevityvault/decoder-3am-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
classify_sleep_cause is one line of Decoder 3am's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
