AI agents call search_spls to retrieve information from DailyMed MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries drug label information from the FDA DailyMed database. It has no side effects—it does not create, modify, delete, or execute any operations. The search functionality with pagination is characteristic of a read-only information retrieval operation.
From the tool's definition Tool performs search and retrieval operations: 'Search for Structured Product Labels (SPLs)', 'searches for drugs then finds related SPLs', 'queries DailyMed SPLs API directly'. Returns paginated results with no modification of underlying data.
Attacks that exploit this kind of access
Search for Structured Product Labels (SPLs) using either simple drug name search or advanced DailyMed API parameters. When using simple query, searches for drugs first then finds related SPLs. When using advanced parameters, queries DailyMed SPLs API directly. Supports pagination for large result sets. It is categorised as a Read tool in the DailyMed MCP Server MCP Server, which means it retrieves data without modifying state.
Register the DailyMed MCP Server MCP server in PolicyLayer and add a rule for search_spls: 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 DailyMed MCP Server. Nothing to install.
search_spls 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 search_spls 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 search_spls. 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.
search_spls is provided by the DailyMed MCP Server MCP server (rowanerasmus/dailymed-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
