What health_signal does on Alderpost
AI agents call health_signal to retrieve information from Alderpost without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why health_signal is rated Low
This tool aggregates and queries health data from NIH RxNorm and FDA sources. It returns scored intelligence responses without modifying any underlying data, executing code, or triggering irreversible actions. While the MCP server charges per call, the tool itself only reads and reports data. The primary function is informational lookup, which is characteristic of Read category tools.
From the tool's definition Tool performs health intelligence queries including 'drug labels, adverse events, recalls, nutrition, drug-to-drug interactions' — all retrieval/lookup operations. No modification, deletion, or execution of external systems.
Attacks that exploit this kind of access
The rule that runs health_signal safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Alderpost, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For health_signal, this is the rule to start with:
health_signal is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Alderpost, apply this rule, and every health_signal call is checked against it from then on.
