Evaluate whether ASM2d fractions fall within typical wastewater ranges.
AI agents call check_fractionation_validity to retrieve information from Aerobic Design MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only validation check by comparing input fractions against established wastewater parameter ranges. It produces informational output (validity assessment) without creating, modifying, deleting, executing code, or committing financial actions. The verb 'evaluate' in the context of checking against ranges is diagnostic in nature, not operational.
From the tool's definition Tool name 'check_fractionation_validity' and description 'Evaluate whether ASM2d fractions fall within typical wastewater ranges' indicate a validation/evaluation function that retrieves or queries data against reference ranges without modifying system state…
Attacks that exploit this kind of access
Evaluate whether ASM2d fractions fall within typical wastewater ranges. It is categorised as a Read tool in the Aerobic Design MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Aerobic Design MCP Server MCP server in PolicyLayer and add a rule for check_fractionation_validity: 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 Aerobic Design MCP Server. Nothing to install.
check_fractionation_validity 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 check_fractionation_validity 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 check_fractionation_validity. 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.
check_fractionation_validity is provided by the Aerobic Design MCP Server MCP server (puran-water/aerobic-design-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
