Get forward links (outgoing) and backlinks (incoming) for a document. Supports [[wikilinks]] and [markdown](links).
AI agents call doc_links 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 retrieves hyperlink and wikilink information from documents to support knowledge base navigation and relationship mapping. It has no side effects, does not modify data, execute code, or access external resources. The blast radius of misuse is minimal—an agent could only discover document relationships already encoded in the source material.
From the tool's definition Tool description states 'Get forward links (outgoing) and backlinks (incoming)' — a retrieval operation that queries existing link metadata without modification. The verb 'Get' indicates a read-only operation.
Documented attack patterns abuse exactly the kind of access doc_links gives an agent:
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_links:
{
"version": "1",
"default": "deny",
"tools": {
"doc_links": {}
}
}doc_links is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get forward links (outgoing) and backlinks (incoming) for a document. Supports [[wikilinks]] and [markdown](links). 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_links: 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_links 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_links 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_links. 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_links 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.
