Read document content at specific addresses. Addresses are strings like
AI agents call doc_read to retrieve information from MinerU Document Explorer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only document retrieval operations. It retrieves content from documents without creating, modifying, deleting, or executing any operations. The description confirms it reads at specific addresses without side effects, fitting the Read category definition of query/fetch operations.
From the tool's definition Tool name 'doc_read' and description 'Read document content at specific addresses' explicitly indicates retrieval of document data with no modification capability.

PolicyLayer is an MCP gateway — it sits between your AI agents and MinerU Document Explorer, and nothing reaches the server without passing your rules. This is the rule we recommend for doc_read:
{
"version": "1",
"default": "deny",
"tools": {
"doc_read": {}
}
}doc_read is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Read document content at specific addresses. Addresses are strings like. It is categorised as a Read tool in the MinerU Document Explorer MCP Server, which means it retrieves data without modifying state.
Register the MinerU Document Explorer MCP server in PolicyLayer and add a rule for doc_read: 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 MinerU Document Explorer. Nothing to install.
doc_read 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 doc_read 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 doc_read. 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.
doc_read is provided by the MinerU Document Explorer MCP server (opendatalab/mineru-document-explorer). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
