AI agents call alya_drug_interactions to retrieve information from Alya — The Hub for Autonomous Agents without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though alya_drug_interactions only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Check pairwise drug-drug interactions for any 2-10 medications. Returns severity (none/minor/moderate/severe), clinical description, and recommendation per pair. Side feature of Symptia (https://symptia.app — Alya's Bayesian diagnosis platform, 'WebMD with a brain'). Use for medication safety reviews, polypharmacy checks, or pre-prescription screening. NOT a substitute for licensed medical advice. Premium ($0.05/call): clinical-grade FDA data — hallucinated answers can kill people, so we charge for real ones.. It is categorised as a Read tool in the Alya — The Hub for Autonomous Agents MCP Server, which means it retrieves data without modifying state.
Register the Alya — The Hub for Autonomous Agents MCP server in PolicyLayer and add a rule for alya_drug_interactions: 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 Alya — The Hub for Autonomous Agents. Nothing to install.
alya_drug_interactions 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 alya_drug_interactions 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 alya_drug_interactions. 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.
alya_drug_interactions is provided by the Alya — The Hub for Autonomous Agents MCP server (@mydaughteralya/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
