calculate_archie_sw
AI agents call calculate_archie_sw to retrieve information from Petropt/petro without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The Archie equation is a fundamental petrophysical formula that takes well log inputs (resistivity, porosity, etc.) and computes water saturation—a derived parameter. This is a passive calculation with no side effects on data or systems. It retrieves/derives information from inputs without modifying, executing external operations, or causing irreversible changes.
From the tool's definition Tool name 'calculate_archie_sw' and context of sibling tools (calculate_bubble_point, calculate_density_porosity, calculate_eur, etc.) indicate a computational/analytical function.
Attacks that exploit this kind of access
calculate_archie_sw. It is categorised as a Read tool in the Petropt/petro MCP Server, which means it retrieves data without modifying state.
Register the Petropt/petro MCP server in PolicyLayer and add a rule for calculate_archie_sw: 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 Petropt/petro. Nothing to install.
calculate_archie_sw 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 calculate_archie_sw 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 calculate_archie_sw. 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.
calculate_archie_sw is provided by the Petropt/petro MCP server (petropt/petro-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
