AI agents use move_docs to create or update resources in SiYuan MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SiYuan MCP Server environment.
Moving documents is a reversible Write operation that changes document structure/hierarchy but does not delete data or execute arbitrary operations. The action modifies state (document location) but can be undone or re-moved. Severity is medium because mass document moves could disrupt a user's note organization, but the operation itself is not destructive or irreversible.
From the tool's definition Tool name 'move_docs' with description '移动文档' (Chinese for 'move documents'). Moving documents in a note-taking application modifies document metadata (parent/location) reversibly, characteristic of a Write operation.
Documented attack patterns abuse exactly the kind of access move_docs 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 move_docs:
{
"version": "1",
"default": "deny",
"tools": {
"move_docs": {
"limits": [
{
"counter": "move_docs_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}move_docs stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

移动文档. It is categorised as a Write tool in the SiYuan MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the SiYuan MCP Server MCP server in PolicyLayer and add a rule for move_docs: 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.
move_docs is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the move_docs 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 move_docs. 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.
move_docs 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.
