[Deprecated] Run optimization. Use run_simulation(mode='optimize') instead.
AI agents invoke run_optimization to trigger actions in PyPSA MCP. 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.
This tool executes an optimization algorithm on an energy system model. While not destructive (optimization doesn't irreversibly delete data) and not financial (doesn't move money), it fits Execute because it: (1) runs computational operations whose outcomes depend on input arguments and model state, (2) triggers external algorithmic operations that modify model results/outputs, and (3) could consume significant…
From the tool's definition Tool performs 'Run optimization' on energy system models, which executes computational operations with effects that depend on model configuration and arguments.
Documented attack patterns abuse exactly the kind of access run_optimization 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 run_optimization:
{
"version": "1",
"default": "deny",
"tools": {
"run_optimization": {
"limits": [
{
"counter": "run_optimization_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}run_optimization 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.

[Deprecated] Run optimization. Use run_simulation(mode='optimize') instead. It is categorised as a Execute tool in the PyPSA MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the PyPSA MCP server in PolicyLayer and add a rule for run_optimization: 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.
run_optimization is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the run_optimization 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 run_optimization. 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.
run_optimization 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.
