AI agents use move_docs_by_id 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 changes their location/hierarchy within the knowledge base structure, which is a reversible modification operation. This is Write-category behavior—data is modified but can be undone by moving documents back. It is not Destructive because the documents themselves are preserved, just repositioned.
From the tool's definition Tool name 'move_docs_by_id' and description '根据ID移动文档' (move documents by ID) indicate document repositioning/reorganization within a notebook structure.

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_by_id:
{
"version": "1",
"default": "deny",
"tools": {
"move_docs_by_id": {
"limits": [
{
"counter": "move_docs_by_id_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}move_docs_by_id 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.

根据ID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_by_id: 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_by_id 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_by_id 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_by_id. 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_by_id 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.
