List documents that link to the specified document.
AI agents call refmd-list-backlinks to retrieve information from RefMD MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a retrieval operation that queries for backlinks to a document. It has no side effects, does not create, modify, or delete data, and does not execute code or trigger external operations. The blast radius of misuse is minimal—it only exposes read access to document link metadata that is likely already accessible through normal document browsing. This is a straightforward Read category tool.
From the tool's definition Tool name 'refmd-list-backlinks' and description 'List documents that link to the specified document' indicate a read-only query operation that retrieves metadata about document relationships without modifying any data.

refmd-list-backlinks 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 refmd-list-backlinks 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.
