WHAT IT DOES

What show_electrostatic_surface does on ChimeraX MCP Server

AI agents invoke show_electrostatic_surface to trigger actions in ChimeraX MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why show_electrostatic_surface needs a policy

This tool performs a computation (calculates electrostatic potential) and then renders/displays the result, which triggers an external operation in ChimeraX. It doesn't merely read data or write/modify stored data reversibly — it executes a computational analysis and visualization pipeline within the ChimeraX application.

Verdict

show_electrostatic_surface Rate-limited

show_electrostatic_surface stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches ChimeraX MCP Server, so you can run agents against it safely.

FAQ

Questions about show_electrostatic_surface

What does the show_electrostatic_surface tool do? +

Calculate and display Coulombic electrostatic potential on the surface. It is categorised as a Execute tool in the ChimeraX MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on show_electrostatic_surface? +

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

What risk level is show_electrostatic_surface? +

show_electrostatic_surface is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit show_electrostatic_surface? +

Yes. Add a rate_limit block to the show_electrostatic_surface 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 show_electrostatic_surface completely? +

Set action: deny in the PolicyLayer policy for show_electrostatic_surface. 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 show_electrostatic_surface? +

show_electrostatic_surface is provided by the ChimeraX MCP Server MCP server (mahynotch/chimerax-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
