Compute magnetic flux through a surface using Φ = B · A · cos(θ)
AI agents call magnetic_flux to retrieve information from Magnetics SME MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only calculation tool that performs mathematical physics computations. It retrieves or computes derived quantities from input values without side effects, state changes, or external operations. The worst case misuse would be an agent requesting incorrect flux calculations, which has no real-world impact beyond wrong advice — a low-severity outcome.
From the tool's definition Tool description states 'Compute magnetic flux through a surface using Φ = B · A · cos(θ)' — a pure calculation/query operation that takes input parameters (magnetic field B, area A, angle θ) and returns a computed result.
Attacks that exploit this kind of access
Compute magnetic flux through a surface using Φ = B · A · cos(θ). It is categorised as a Read tool in the Magnetics SME MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Magnetics SME MCP Server MCP server in PolicyLayer and add a rule for magnetic_flux: 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 Magnetics SME MCP Server. Nothing to install.
magnetic_flux 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 magnetic_flux 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 magnetic_flux. 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.
magnetic_flux is provided by the Magnetics SME MCP Server MCP server (jkearney126/maxwell_bot). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
