AI agents call configure_mcp_plan to retrieve information from 1mcpserver without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool description says it only 'returns a plan', which implies it is reading/generating advisory output without side effects. However, the description is vague and the broader server context involves configuring MCP servers, which could mean the plan output triggers downstream configuration actions. Classified as Read due to the passive 'returns' language, but confidence is moderate given the sparse description.
From the tool's definition Returns a plan for the next steps to do.
Documented attack patterns abuse exactly the kind of access configure_mcp_plan gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and 1mcpserver, and nothing reaches the server without passing your rules. This is the rule we recommend for configure_mcp_plan:
{
"version": "1",
"default": "deny",
"tools": {
"configure_mcp_plan": {}
}
}configure_mcp_plan is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Returns a plan for the next steps to do. It is categorised as a Read tool in the 1mcpserver MCP Server, which means it retrieves data without modifying state.
Register the 1mcpserver MCP server in PolicyLayer and add a rule for configure_mcp_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 1mcpserver. Nothing to install.
configure_mcp_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 configure_mcp_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 configure_mcp_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.
configure_mcp_plan is provided by the 1mcpserver MCP server (particlefuture/1mcpserver). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
