AI agents call get_boot_progress to retrieve information from SiYuan 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 the boot/startup progress of the SiYuan application. It is a read-only operation that queries current state and returns information with no side effects. There is no data creation, modification, deletion, or external execution involved. The low severity reflects minimal security risk from an AI misusing this information-retrieval tool.
From the tool's definition Tool name 'get_boot_progress' and description '获取启动进度' (get startup progress) indicate a query operation that retrieves status information without modifying state.
Documented attack patterns abuse exactly the kind of access get_boot_progress gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SiYuan MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_boot_progress:
{
"version": "1",
"default": "deny",
"tools": {
"get_boot_progress": {}
}
}get_boot_progress is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

获取启动进度. It is categorised as a Read tool in the SiYuan MCP Server MCP Server, which means it retrieves data without modifying state.
Register the SiYuan MCP Server MCP server in PolicyLayer and add a rule for get_boot_progress: 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 SiYuan MCP Server. Nothing to install.
get_boot_progress 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 get_boot_progress 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 get_boot_progress. 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.
get_boot_progress is provided by the SiYuan MCP Server MCP server (xgq18237/siyuan_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
