AI agents call load_plan to retrieve information from Context Engine MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and reads an existing plan without causing side effects. It is a straightforward data retrieval operation, making it a Read category tool with low severity. An AI agent misusing this tool could at worst retrieve unintended plans, but cannot modify or delete them.
From the tool's definition Tool name 'load_plan' and description 'Load a previously saved plan by ID or name' indicate a retrieval operation. No modification, execution, deletion, or financial action is described.
Documented attack patterns abuse exactly the kind of access load_plan gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Context Engine MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for load_plan:
{
"version": "1",
"default": "deny",
"tools": {
"load_plan": {}
}
}load_plan is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Load a previously saved plan by ID or name. It is categorised as a Read tool in the Context Engine MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Context Engine MCP Server MCP server in PolicyLayer and add a rule for load_plan: 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 Context Engine MCP Server. Nothing to install.
load_plan 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 load_plan 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 load_plan. 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.
load_plan is provided by the Context Engine MCP Server MCP server (kirachon/context-engine). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Context Engine MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
