Calculate porosity from bulk density log.
AI agents call calculate_density_porosity 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.
This tool reads well log data (bulk density values) and performs a mathematical calculation to derive porosity, returning computed results. It has no side effects, does not modify data, and does not execute arbitrary code or external operations. The input is read-only analysis of petroleum engineering data, making it a Read category tool with low severity risk.
From the tool's definition Tool name 'calculate_density_porosity' and description 'Calculate porosity from bulk density log' indicate a computation performed on existing log data without modification, creation, or deletion of records.
Attacks that exploit this kind of access
Calculate porosity from bulk density log. 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_density_porosity: 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_density_porosity 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_density_porosity 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_density_porosity. 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_density_porosity 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.
