WHAT IT DOES

What gas_z_factor does on pyResToolbox MCP Server

AI agents call gas_z_factor to retrieve information from pyResToolbox MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why gas_z_factor is rated Low

Based on the tool name and server context (petroleum engineering calculations, PVT analysis), this tool likely computes the gas Z-factor (compressibility factor) from input parameters. This is a read/calculate operation with no side effects. Empty description lowers confidence slightly, but the naming convention and server context are consistent with a pure calculation tool.

From the tool's definition Tool name 'gas_z_factor' suggests a calculation/lookup of the gas compressibility (Z) factor, a standard PVT property. Description is empty.

RECOMMENDED RULE

The rule that runs gas_z_factor safely

PolicyLayer is an MCP gateway: it sits between your AI agents and pyResToolbox MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For gas_z_factor, this is the rule to start with:

gas_z_factor Allowed

gas_z_factor is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "gas_z_factor": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect pyResToolbox MCP Server, apply this rule, and every gas_z_factor call is checked against it from then on.

How do I enforce a policy on gas_z_factor? +

Register the pyResToolbox MCP Server MCP server in PolicyLayer and add a rule for gas_z_factor: 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 pyResToolbox MCP Server. Nothing to install.

What risk level is gas_z_factor? +

gas_z_factor is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit gas_z_factor? +

Yes. Add a rate_limit block to the gas_z_factor 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.

How do I block gas_z_factor completely? +

Set action: deny in the PolicyLayer policy for gas_z_factor. 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.

What MCP server provides gas_z_factor? +

gas_z_factor is provided by the pyResToolbox MCP Server MCP server (gabrielserrao/pyrestoolbox-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
