List all available PyPSA component types with descriptions.
AI agents call list_component_types to retrieve information from PyPSA MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about available component types in PyPSA without modifying, creating, deleting, or executing any operations on the energy model. It is a pure read operation that has minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'list_component_types' and description 'List all available PyPSA component types with descriptions' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_component_types gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and PyPSA MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for list_component_types:
{
"version": "1",
"default": "deny",
"tools": {
"list_component_types": {}
}
}list_component_types is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all available PyPSA component types with descriptions. It is categorised as a Read tool in the PyPSA MCP MCP Server, which means it retrieves data without modifying state.
Register the PyPSA MCP server in PolicyLayer and add a rule for list_component_types: 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 PyPSA MCP. Nothing to install.
list_component_types 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 list_component_types 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 list_component_types. 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.
list_component_types is provided by the PyPSA MCP server (open-energy-transition/pypsa-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
